Door types in floor plans
Every door type in a residential floor plan — what it is, where it came from, the standard sizes, the materials, the hardware, the cost, when it's the right call, and how Room Sketch 3D represents it. The definitive reference.
A door does three things at once: it controls who and what passes between two spaces, it controls light and sound, and it occupies floor area — either as a swing arc, a slide path, or a parking zone. Every door type in residential construction trades these three concerns differently, and the right choice for any given opening comes down to which trade-off you can live with.
Doors have been engineered for at least five thousand years. The hinged door — a panel pivoting on a vertical axis at one side — predates writing; the earliest evidence of pivot hinges (the predecessor of modern butt hinges) comes from Mesopotamian temples. Sliding doors appear in classical Greek and Roman houses. Pocket doors became fashionable in mid-19th-century America (the Victorian era), driven by the need to subdivide parlors that doubled as ballrooms. Barn doors are a 21st-century revival of a medieval European mechanism — track-mounted sliding doors used on outbuildings — repurposed as an interior design feature when modern construction made traditional pocket doors expensive to retrofit. None of these designs are recent inventions; the most modern door technology in your house is probably the hardware (soft-close, magnetic, smart-lock), not the panel itself.
This page is the master index. It covers eleven door types — the six that ship in Room Sketch 3D's Build Panel, plus five additional types you may encounter in floor plans (Dutch, bifold, accordion, pivot, automatic) that we represent as variants of the supported six. Each type gets a short summary here, with a deep-dive page linked. If you only read three sections, read the hinged-door section (it covers the majority of doors in any home), the comparison matrix at the bottom, and the section on how Room Sketch 3D actually models each type.

Hinged (swing) door — the default everywhere
Mechanism. A rigid rectangular panel attached to a frame by two or three hinges along one vertical edge. The panel pivots about that edge through a quarter-circle (90°) or, with offset hinges, slightly more. The opposite edge carries the latch and handle. When closed, the panel seals against the door stop on three sides (top, latch-side, hinge-side) and the threshold or floor on the fourth. Why it dominates. A hinged door is the simplest mechanism that satisfies the three primary requirements — separation, light/sound control, and human passage — using one moving part, no track, and no power. It scales from 18-inch closet doors to 12-foot vault doors using the same physics. The hardware is universal and cheap. Every other door type either solves an edge case the hinged door can't (no room for the swing, opening too wide for one leaf, exterior weather demands) or trades cost for a different aesthetic. Standard residential widths. - Bedroom and bathroom interior: 30–32 inches. - Walk-in closet, pantry: 28–32 inches. - Linen closet: 24–28 inches. - Main entry, master bedroom: 36 inches. - Accessible doorway (US ADA-equivalent): 36 inches minimum (32-inch clear opening when door is at 90°). - Commercial main entries: 36–42 inches. Standard heights. Interior: 80 inches (6'8") in nearly all post-1950 US construction. Exterior: 80 inches standard; 84 (7') in higher-end homes; 96 (8') in luxury / contemporary. Older homes (pre-1950) sometimes have 78-inch interior doors — confirm before specifying. Door thickness. Interior 1⅜″ (35 mm); exterior 1¾″ (44 mm). Solid-core interior doors share the exterior thickness because the extra mass dampens sound. Materials. Interior: hollow-core particleboard or honeycomb (cheapest, ~$30–60 retail); solid-core composite or MDF (sound dampening, $80–200); solid wood ($150–600+); steel or aluminum (commercial, fire-rated). Exterior: solid wood, fiberglass with foam core, insulated steel. Hardware. Two or three hinges (butt, ball-bearing, concealed European). Latchset: passage (no lock), privacy (push-button bedroom/bathroom), keyed entry, deadbolt. Pulls: lever or knob, increasingly smart locks. Cost (US, installed, 2024 prices). Hollow-core interior: $150–300. Solid-core: $300–600. Solid wood interior: $400–1,200. Front entry door (insulated steel/fiberglass): $800–3,000. Custom mahogany or sculpted: $3,000–15,000+. Floor area reserved. A quarter-circle swing arc with radius equal to the door width. A 32-inch door reserves ~7 sq ft of floor. When to choose. Almost every interior opening. If the opening fits 30-36 inches and has arc clearance, the hinged door is the right answer 80% of the time. In Room Sketch 3D. Build Panel → Doors → Door tile. Inspector exposes width, hinge side (left/right), swing direction (inward/outward), show-arc toggle, color. See hinged swing doors for the full deep-dive.

French door — paired hinged leaves for wide openings
Mechanism. Two hinged leaves, one hinged on each side of a single wide opening, meeting at the center (sometimes flush, sometimes against a vertical mullion called an 'astragal'). Both leaves swing — typically both inward — and one is often the 'active' leaf (used daily) while the other is the 'inactive' leaf (held closed by floor and head bolts unless needed for moving furniture). Etymology. The name 'French' is misleading: the design originated during the Renaissance and spread from Italy through France in the 16th and 17th centuries. The defining feature historically was the use of multiple small glass panes ('lites') divided by muntins — the door was a window-wall section that opened. The form became associated with French Baroque architecture and exported widely. Today, 'French door' refers to the pair-of-hinged-leaves form regardless of glazing. Standard widths. - Interior pair: 48–72 inches total. Each leaf 24–36 inches. - Common interior standard: two 30-inch leaves = 60 inches total. - Exterior pair: 60–72 inches total. - Multi-panel (4 or 6 leaves): 96–144 inches. Heights. 80 inches (6'8") standard interior; 84 (7') exterior and formal; 96 (8') grand. Panel styles. - Full-glass ("true-divided lites" or single-pane): Maximum daylight transfer. The classic French look. Used most often interior-to-exterior or between formally-lit rooms. - Partial glass (over wood/solid): Glass in the upper section, solid panel below. A compromise that gives daylight and privacy in adjacent zones (e.g. patio access from a dining room — glass at eye level, solid below table height). - Solid wood (panel doors): No glass. Reads more 'double door' than 'French door' but uses the same hardware. Common for pantry and closet wide openings. - Metal grill over glass: Decorative metal lattice — Mediterranean, Spanish Colonial, traditional regional styles. Hardware specifics. Standard pair has two hinges per leaf (so four hinges total), a passive leaf bolt at floor and head, and the active leaf carries the latch. Exterior French doors add weatherstripping along the meeting edge and a center sealing astragal. Material and cost (installed, US 2024). Interior pair, paint-grade: $700–1,500. Interior solid wood: $1,500–4,000. Exterior weather-rated: $2,500–8,000+. Floor area reserved. Two quarter-circle arcs, each with radius equal to one leaf's width. A 60-inch French door (two 30-inch leaves) reserves two ~5 sq ft arcs on the swing side. When to choose. Wide interior transitions (master bedroom suite entry, formal living to dining); exterior to patio when you want full-width opening, formal hardware, and daylight; any opening 48–96 inches wide where a single hinged door is impossible and you don't want the contemporary look of a slider. Common variant: "double doors." Many residential builders use 'double door' to mean exactly what's described here — a French door without glass. Functionally identical; the term differs by region. In Room Sketch 3D. Build Panel → Doors → French Door tile. Inspector exposes total width, panel count (2/4/6), panel style (glass / wood / metal-grill), color, swing direction. See french doors for the full deep-dive and french vs sliding glass doors for the patio-door comparison.

Sliding glass door — patio standard, also called a 'patio door'
Mechanism. Two or more large glazed panels in a single frame. At least one panel slides horizontally on a top-and-bottom track system, passing in front of (or behind) the other panel(s). Roller assemblies at the bottom carry the panel weight; nylon guides at the top keep it vertical. The fixed panel(s) are weather-sealed in place. Configuration nomenclature. Letters describe each panel: O = fixed (operable's opposite); X = sliding. Read left-to-right facing the door from outside. - OX: Fixed left, slider right. - XO: Slider left, fixed right. - OXO: Fixed-slider-fixed (3-panel). - OXXO: Two sliders meeting in the center, fixed on each end (4-panel). - Multi-slide / pocket-slide: All panels slide; some retract into a wall cavity for full-opening configurations. History. Sliding glass doors as a residential type emerged in the late 1940s with the post-war ranch-house boom in California, where mild climate and indoor-outdoor living drove demand. Aluminum extrusion made wide-panel frames affordable; tempered safety glass (mandatory in residential sliders since the early 1970s) made them safer. The genre was sometimes called a 'California door' in the 1950s. Standard sizes. - Two-panel: 60–96 inches wide × 80 inches tall. 72 and 96 are most common. - Three-panel: 96–144 inches × 80. - Four-panel: 120–192 × 80. - Multi-slide: 144–360+ inches. Effective opening. Critical to plan: a two-panel slider opens half its width. A 96-inch slider gives a 48-inch effective opening; the other 48 is fixed. Three- and four-panel sliders give different ratios — OXO gives 33% (the middle panel slides over one end); OXXO gives 50% (both sliders meeting in the center). Glass. Almost always tempered safety glass (shatters into small pebbles instead of large shards). Often dual-pane (insulated glass unit, IGU) with argon fill and low-emissivity (low-e) coating. Triple-pane in cold climates. Frame materials. Aluminum (cheapest, conducts heat — thermally broken aluminum is better); vinyl/uPVC (good thermal performance, lower cost); fiberglass (high performance, premium); wood-clad (interior wood face, exterior aluminum or fiberglass — heritage look, premium price). Cost (US, installed 2024). Two-panel aluminum: $1,500–3,500. Two-panel vinyl: $1,800–4,500. Two-panel fiberglass: $3,500–7,500. Multi-slide / pocket-slide: $8,000–30,000+ (significant structural and finish work). Maintenance. Sliding tracks collect dirt, pet hair, and debris — clean tracks monthly with a vacuum. Rollers wear over 15–25 years and may need replacement. Weatherstripping degrades; replace every 8–15 years. Floor area reserved. Zero swing arc. But the wall behind the sliding panel(s) must remain clear of tall furniture that would block the panel from sliding fully open. Plan furniture against the OPPOSITE wall in any room with a slider. When to choose. Patios, balconies, decks — anywhere indoor-outdoor connection is the design goal. Modern and contemporary architecture. Wide openings (8+ feet) where French door arcs would dominate the room. Tight rooms where any swing arc would block furniture. View walls where uninterrupted glass is the point. When NOT to choose. Traditional / Colonial / Craftsman houses (looks anachronistic). Formal interior transitions (looks utility, not formal). Bedrooms (privacy concerns, plus most areas restrict glazing area in sleeping rooms). Doors that must open fully wider than half the panel width (use French or multi-slide instead). In Room Sketch 3D. Build Panel → Doors → Sliding Glass tile. Inspector exposes width, panel count, color. See sliding glass doors for the full deep-dive.

Sliding wood door — the interior cousin
Mechanism. Same as sliding glass — horizontal track, panels passing each other — but with solid wood panels instead of glazed. Two configurations dominate: bypass (panels on parallel tracks, sliding past each other inside the door opening) and barn-style (single panel on a track mounted to the wall's outer face, sliding past the opening — covered separately as barn doors). Why a separate category from sliding glass. Wood sliding doors are interior fixtures with different aesthetics, different hardware (lighter rollers, simpler frame), different glass requirements (none), and different use cases (closets and storage instead of patios). Treating them as a distinct type matches the way real catalogs and builders specify them. Standard sizes. - Two-panel bypass closet: 48–96 inches wide × 80 inches tall. 60 and 72 are most common closet widths. - Three-panel bypass: 72–120 inches × 80. - Wider configurations are uncommon — past 120 inches, bifold or accordion doors usually compete. Effective opening. A two-panel bypass opens half its width (same as a two-panel slider). A 60-inch bypass exposes 30 inches at a time. This limitation is why bifold and barn doors compete for closet duty when wider access matters. Materials. Hollow-core flush; solid-core flush; raised-panel; mirrored (glass mirror laminated onto wood panel, common for closets so the panel doubles as a dressing mirror); louvered (for closets needing ventilation). Cost (US, installed 2024). Two-panel bypass kit: $200–800. Three-panel: $400–1,200. Floor area reserved. Zero swing arc. But both ends of the door opening must be accessible from the room — don't park furniture directly against the side the panel slides toward. When to choose. Wide closets (48–96 inches). Laundry alcoves. Pantries where the door is rarely open and full-width access isn't needed. As an aesthetic alternative to bifold doors (cleaner panels, less hinge mechanism). When NOT to choose. Closets where full-width access matters (use bifold or barn instead). Anywhere a single 30-inch hinged door would be enough (sliding is overkill below 48 inches). In Room Sketch 3D. Build Panel → Doors → Sliding Wood tile. Inspector exposes width and panel count. See sliding wood doors.

Pocket door — disappears into the wall
Mechanism. A single door panel hangs from a horizontal top-track inside a hollow cavity built between two parallel wall studs. The cavity is wider than a normal stud bay (two studs spaced ~6 inches apart instead of 16 on-center) and extends roughly twice the door's width along the wall. When the door slides open, it disappears entirely into this cavity. When closed, only the panel is visible — flush with both wall faces, indistinguishable from a hinged door at first glance except for the recessed pull (a standard knob would catch on the wall as the door retracts). History. Pocket doors achieved their peak popularity in the United States between 1850 and 1910 — the Victorian and Edwardian eras. Period parlors were designed to serve double duty: closed off for formal entertaining, opened wide for dancing or large gatherings. Sliding pocket doors between parlor and dining room (often a wide pair meeting in the center, both pocketing into opposite walls) were standard in middle-class urban housing of the period. The form fell out of fashion in the early-to-mid 20th century as house plans simplified and ranch-style open floors became common, then revived in the 1990s as space efficiency in smaller homes and apartments became valued again. Standard sizes. - Width: 28–42 inches. 32 inches is the most common interior width. - 36 inches for accessible openings. - Height: 80 inches (6'8") standard. - Wall cavity: roughly 2× the door width. A 32-inch door needs ~64 inches of clear adjacent wall for the cavity. Hardware. Top-hung roller system (most common modern design) with two ball-bearing trolleys riding a steel track at the top of the cavity. The bottom of the door has only a guide (no weight-bearing roller) to prevent it from swinging. Pulls: recessed (flush) pulls on both faces of the door so it can disappear fully. Edge pulls for the leading edge. Construction. New construction: framed during rough framing using a 'pocket door kit' (Johnson Hardware and Eclisse are the dominant manufacturers). The kit comes pre-assembled — track, split studs, header — and is installed in place of a normal stud bay. The drywall covers both sides of the cavity; the door slides into the void. Retrofit. Possible but invasive. Existing wall must be opened to the studs on one side, the kit installed, and the wall closed back up — typically requires removing drywall, electrical relocations if outlets/switches were in the cavity area, and finishing both sides. Cost typically $3,000–8,000 per retrofitted door. Cost (US, installed 2024). New construction: $1,500–3,500. Retrofit: $3,000–8,000. Wall constraints (when pocket doors don't work). - Wall too short (under 2× door width) — no cavity space. - Plumbing in the cavity wall — water lines and drains cannot share the void. - Major electrical runs through the wall — limited; minor lines can route around the cavity. - Structural members crossing the wall — beams, posts, headers, or load-bearing studs. - Heat ducts in the wall — typical HVAC chases preempt the cavity. Limitations. - Cavity wall is hollow — can't hang heavy art, shelves, or a wall-mount TV on it. - Hardware fails over time — rollers wear, doors begin to bind. Repair requires opening the wall. - Sound transmission slightly worse than a hinged door (the panel sits ~⅛ inch off the jamb). When to choose. Tight spaces where a hinged door's swing would block walkways or furniture. Powder rooms, small en-suites, study nooks, butler's pantry entries. Wide openings between rooms (a single 48-inch pocket door instead of two 30-inch French doors, when you can engineer the cavity). In Room Sketch 3D. Build Panel → Doors → Pocket Door tile. Inspector exposes width and a track-length override for walls shorter than the default 2× cavity. See pocket doors and pocket vs barn door for the comparison with the cheaper retrofit alternative.

Barn door — track on the wall's outer face
Mechanism. A single panel hangs from rollers gripping a horizontal track mounted to the outside of the wall, above the door opening. The panel slides past the opening (not into the wall) on the rollers. A floor guide at the bottom keeps the panel from swinging outward. When closed, the panel overlaps the opening by 1–3 inches on each side, sealing reasonably well against the wall. When open, the panel parks against the wall on one side of the opening. Etymology. The name comes from the literal source: the track-and-roller system used on traditional agricultural barn doors for at least 200 years. The medieval/early-modern version used wooden tracks and iron rollers; modern barn doors use steel tracks and ball-bearing rollers. The translation from utility to interior design feature became fashionable around 2010–2012 in American residential renovation, popularized by HGTV-style renovation shows and Pinterest. By the late 2010s, barn doors had moved from trendy to a standard interior-design vocabulary item, especially in modern farmhouse, industrial, and modernist styles. Standard sizes. - Single panel: 28–60 inches wide × 80 inches tall. 36 inches is most common. - Double barn-style (two panels meeting in the center): 56–96 inches total. - Track length: door width + 6–12 inches of overlap on the parking side. A 36-inch door needs 42–48 inches of track. Hardware. Steel track (1.5–2 inch diameter rail typically) bolted to studs above the opening. Two roller hangers grip the track and carry the door panel. Floor guide at the bottom. The hardware is visible — and the visibility is part of the design appeal. Door panel styles. - K-style/Z-style/X-style: Cross-bracing on the face — heritage barn look. Common in farmhouse and rustic interiors. - Plank: Vertical or horizontal solid wood planks. Modern farmhouse. - Frame-and-panel: Traditional wood door styles adapted to barn-track hardware. Reads transitional. - Glass-paneled: Modern industrial — steel-framed glass panel slid as a barn door. - Mirror-faced: Closet barn doors with a full-length mirror. Cost (US, installed 2024). Hardware kit alone: $80–500. Hardware + plain wood door: $300–800. Hardware + custom door: $800–2,500. Premium designer hardware (e.g., soft-close, smart): $1,500–4,000. Limitations. - Sound and light leak around all four edges (the door sits 1–2 inches off the wall for roller clearance). Not suitable for bedrooms or offices needing privacy. - The wall the door parks against cannot have anything mounted on it — no shelves, no thermostats, no switches. - The track and hardware are always visible. If the design language doesn't include the hardware, it looks bolted-on. - Door swings slightly at the bottom edge during slide — the floor guide controls this but can squeak or wear. Floor area reserved. Zero swing arc. The parking side of the wall must be clear for the door to open fully. When to choose. Retrofit applications where opening the wall for a pocket door isn't feasible. Aesthetic statement piece in modern farmhouse, industrial, or modernist interiors. Master closet entries, bathroom entries (where modest privacy is acceptable), pantries, laundry alcoves. When NOT to choose. Bedrooms (sound/light privacy). Home offices (same). Spaces where the visible hardware would clash with the design language (formal classical interiors, traditional Federal-style). In Room Sketch 3D. Build Panel → Doors → Barn Door tile. Inspector exposes width, track length, and which side of the wall the track mounts on. See barn doors and pocket vs barn door.

Opening — no door at all
Mechanism. None. An opening is a doorway with no door panel — a finished gap in a wall that separates rooms without a closable barrier. Subdivided into two finish types: cased (trim around the opening, like a hinged door's frame minus the door) and uncased (drywall returned into the opening with no trim). When to choose. Open-plan transitions between rooms where privacy, sound, or smell separation aren't needed — kitchen to dining, living to hallway, entry to living. Wide architectural moves (6–10+ feet) where any door would feel inappropriate. Pass-throughs and half-wall openings between kitchens and dining rooms. Standard widths. - Narrow passage: 30–36 inches. - Standard interior opening: 36–60 inches. - Wide architectural opening: 60–96 inches. - Full wall opening: 96+ inches. Header height. A 7-foot opening with a header that drops 12 inches below an 8-foot ceiling reads formal — like a deliberate threshold. A full-ceiling opening (no header below the ceiling) reads open — like the wall just stops. Both are intentional design choices. Cost. Almost nothing — just framing the rough opening, casing trim if cased, and drywall finishing. $100–500 for the opening itself. In Room Sketch 3D. Build Panel → Doors → Opening tile. Inspector exposes width and (in future) header height. See openings and passageways and cased vs uncased openings.

Other door types we don't ship as separate tiles
Five door types you'll encounter in floor plans that Room Sketch 3D models as variants of the six above, rather than as their own tiles: Dutch door. A hinged door split horizontally — the top half can open while the bottom stays closed. Common in nurseries, pantries that double as serving counters, and historic farmhouse exteriors. Model as a standard hinged door; note the split in the design name. Bifold door. Two narrow panels hinged to each other; one or two units across a wide opening. Common on closets (alternative to bypass sliders). The panels fold against each other when opened — they don't slide and don't swing. Model as a sliding wood door for closet duty; the floor-plan footprint is similar. Accordion door. Multi-panel folding door — more than two panels per side, hinged to each other. Maximum opening width per square foot of wall. Common in commercial spaces, room dividers, large closets. Model as a sliding wood door or French door depending on the appearance. Pivot door. A door panel that rotates about a vertical axis NOT at its edge but at an offset point on the top and bottom (typically 1/4 of the panel width from the leading edge). The panel rotates 90° but doesn't have hinges. Used for large, heavy, or signature entry doors — the visible mechanism is two small pivots, top and bottom, rather than three hinges on the side. The swing arc is more complex (an arc plus a partial back-swing). Model as a standard hinged door for floor-plan accuracy. Automatic / motorized door. Sliding or swing doors with electric operators. Common on commercial main entries. Mechanically identical to manual versions for floor-plan purposes — the operator and motion sensors are above the door, not in the floor plan.

Door type comparison matrix
Side-by-side comparison of the six door types Room Sketch 3D ships as tiles. Use this when you're choosing for a specific opening. | Type | Swing arc | Cost (installed) | Sound isolation | Light isolation | Retrofit ease | Architectural style | |---|---|---|---|---|---|---| | Hinged | Yes (door-width radius) | $150–$1,200 | Excellent | Excellent | Easy | Universal | | French | Yes (two arcs) | $700–$4,000+ | Good | Variable (depends on glazing) | Easy | Traditional, transitional | | Sliding glass | None | $1,500–$8,000+ | Good (modern) / Poor (older) | Very poor (mostly glass) | Hard (header + sill rough-in) | Modern, contemporary | | Sliding wood (bypass) | None | $200–$800 | Fair (gaps at track) | Good | Easy (replace existing closet doors) | Universal closet | | Pocket | None | $1,500–$8,000+ | Good | Good | Hard (open wall) | Universal, especially space-tight | | Barn | None | $300–$2,500 | Poor (gaps at edges) | Poor (light leaks edges) | Very easy | Farmhouse, modern, industrial | Notes on the matrix: - 'Sound isolation' refers to the door's ability to block speech and ambient sound, not full STC ratings. - 'Retrofit ease' is the difficulty of installing the door type in an existing wall. - 'Cost (installed)' includes door, hardware, framing if any, and labor. Premium designs can exceed these ranges.

Selection criteria — how to pick the right door type for an opening
A decision tree, in plain English: 1. Is the opening 36 inches wide or less? - Yes → Hinged door, unless there's no swing clearance. If no clearance: pocket door (new construction) or barn door (retrofit). - No → continue. 2. Is the opening 36–48 inches wide? - Yes → Single wide hinged door, or pocket door if no swing arc. - No → continue. 3. Is the opening 48–72 inches wide and interior? - Yes → French door (formal), or sliding wood / pocket / barn (casual/utility). Choose based on style. - No → continue. 4. Is the opening 60–96+ inches wide and exterior (patio, balcony)? - Yes → Sliding glass (default), or French (formal), or multi-slide (luxury/wide). 5. Is the opening over 8 feet wide? - Multi-panel sliding glass, multi-panel French, or pocket-slide. 6. Does the opening need NO closure (e.g. living-to-dining transition)? - Opening (no door). Other factors that override the above: - Architectural style of the rest of the house (Victorian → French + pocket; Mid-century modern → sliding; Modern farmhouse → barn doors). - Sound/light privacy required (bedroom → hinged or pocket; bathroom in a small home → pocket or barn; closets → bypass or hinged). - Floor space available for swing arc (tight rooms → sliders). - Construction phase — new construction allows pocket doors; retrofit usually pushes to barn or surface-mount sliders.

How Room Sketch 3D represents each type
Every door type is added the same way: pick the type's tile in the Build Panel → Doors section, click the wall, set Inspector values, verify in 3D. The six tiles in the Build Panel: 1. Door — standard hinged. 2. French Door — paired hinged leaves with configurable panel count and style. 3. Sliding Glass — sliding patio door with configurable panel count. 4. Sliding Wood — interior sliding (closet bypass) with configurable panel count. 5. Pocket Door — slides into wall with optional track-length override. 6. Barn Door — surface-mount sliding with In Side / Out Side selection. A seventh tile, Opening, lives in the same section for door-less passages. Smart Flow Check enforces clearances automatically: - Hinged and French doors: quarter-circle swing arcs are flagged if furniture intrudes. - All sliding types: panels' parking side is checked for blockages. - Openings: no clearance is enforced beyond the standard 36-inch walkway. The 3D view renders each type accurately — hinged doors show the panel partway open by default (so you can see the swing); sliders render with glass and panels; pocket doors render invisible when 'open' (with the panel fully retracted into the wall); barn doors show the track and panel visible.
Tips
Default to hinged; reach for alternatives when forced
A hinged door is cheaper, more reliable, more familiar, and seals better than any alternative. Use it unless there's a real reason not to — no swing clearance, opening too wide for one leaf, aesthetic requirement, or new construction taking advantage of the pocket-door wall cavity.
Pick the door type before you specify the width
The width that 'looks right' depends on the type. A 36-inch hinged door looks generous; a 36-inch pocket door looks normal; a 36-inch sliding glass door looks comically small for a patio. Decide the type first, then the width.
Match the door's visibility to the design language
Hinged and French doors visually disappear when open (panel lies flat against wall). Pocket doors disappear completely. Sliding glass dominates a wall. Barn doors are always visible. Make the type's permanent visual weight part of the choice.
Plan for both sides of the door, not just the swing side
A door has TWO approach zones — one on each side. Both need 36 inches of clear walkway. A hinged door also needs latch-side clearance (18 inches) on the side where the handle is. Smart Flow Check enforces the swing arc; the approaches are on you.
Doors are the most-used hardware in any house
Front entry: 10+ operations per day. Bedroom: 5+. Bathroom: 8+. Cheap hardware costs less up front but fails first. Budget extra for hinges, latchsets, and pulls on the doors used most.
Common confusions
Modeling a 60-inch single hinged door
A single hinged door at 60 inches wide doesn't exist in residential construction. The leaf would be too heavy for standard hinges, would sag visibly within a year, and looks wrong proportionally. At 48+ inches the opening is a French door, a sliding door, or an opening. Pick the right type.
Pocket door on a wall already carrying systems
Plumbing, structural members, or main electrical runs in the receiving wall kill the pocket-door cavity. Always confirm what's in the adjacent wall before specifying a pocket door — moving plumbing to another wall costs more than the door.
Barn door on a bedroom
Barn doors leak sound and light through gaps along all four edges. Bedrooms need real privacy. Use hinged (with clearance) or pocket (cleaner, sealed) for bedrooms; reserve barn for closets, pantries, and non-private spaces.
Sliding glass door swung-direction confusion
Sliding doors don't swing. People still ask which way they 'swing' (the slider direction is what they usually mean). When specifying, give the panel direction (left-sliding or right-sliding) and the configuration (OX, XO, OXO).
Treating French doors as decorative-only
Both leaves of a French door must function. If the inactive leaf doesn't actually open, the door is decorative — and the hardware (floor bolts, head bolts) won't work right over time. Use double doors with a center mullion if you only need one leaf operational.
Frequently asked questions
What are the most common door types in a typical residential house?
Hinged (swing) doors are the overwhelming majority — typically 80–90% of doors in a house. The rest break down: sliding wood (bypass) for closets (5–10%), sliding glass for patio access (1 per house typically), and pocket or barn for tight spaces (0–3 per house). French doors are formal accents — 0–2 per house.
What's the difference between a pocket door and a barn door?
Pocket doors slide INTO the wall through a hollow cavity built between the studs. When open, the door is invisible — flush with both wall faces. Barn doors slide ACROSS the wall on a surface-mounted track. When open, the door is parked visibly against the wall to one side of the opening. Pocket doors are cleaner architecturally; barn doors are dramatically cheaper to retrofit (no wall opening required) and serve as a visible design feature. See pocket vs barn door for the deep comparison.
How wide should an interior door be?
Standard interior bedroom and bathroom doors: 30–32 inches wide. 32 is the most common contemporary standard; 30 in tight walls or older construction. Walk-in closets and pantries: 28–32 inches. Linen closets: 24–28 inches. Main entry and master bedroom: 36 inches. Accessible openings: 36 inches minimum. For wider openings (48+ inches), use a French door or sliding door instead of a single oversized hinged door.
Which door types don't need a swing arc?
All sliding variants — sliding glass, sliding wood (bypass), pocket, and barn doors slide horizontally on tracks. None require swing-arc clearance. Openings (door-less passages) also need no swing arc. Use these types whenever floor space for a swing is tight or when furniture against a wall would conflict with a hinged door's quarter-circle.
What's the difference between a French door and a double door?
Functionally, none. Both refer to two hinged leaves meeting in the center of a wide opening, each hinged on the outer edge. By regional convention, 'French door' more often refers to the version with glass panels (the historical form), while 'double door' more often refers to all-wood versions used internally for pantries, mudrooms, or closets. Builders and catalogs use the terms interchangeably. Room Sketch 3D's French Door tile handles both — set the panel style (glass / wood / metal-grill) in the Inspector.
Can a sliding glass door open the full width of the opening?
No — a standard two-panel sliding glass door opens only half its width. The other half is a fixed panel. A 96-inch slider gives a 48-inch effective opening. For full-width opening at this scale, use a multi-slide (pocket-slide) door — where all panels slide and retract into a wall cavity, opening the entire opening — or a French door pair, which swings open at both leaves for a full-width opening. Multi-slide doors are significantly more expensive (5–10× a standard slider) due to structural and finish work.
Where do I add a door in Room Sketch 3D?
Build Panel → Doors. Six tiles cover every door type: Door (standard hinged), French Door (paired leaves with configurable panel style), Sliding Glass (patio slider with configurable panel count), Sliding Wood (interior bypass closet door), Pocket Door (with track-length override), Barn Door (with In Side / Out Side selection). An Opening tile in the same section handles door-less passages. Click the tile, then click the wall — the door lands at a default position, and the Inspector exposes width, hinge side, swing direction, and other type-specific options.
How are door swing arcs enforced in Room Sketch 3D?
Smart Flow Check is always on. When you set the hinge side and swing direction on a hinged or French door, the swing arc is calculated automatically and treated as a no-furniture zone. Any furniture piece that overlaps the arc generates a real-time warning ('Move it away from the door swing'). The warning vanishes the moment the piece is moved out of the arc. Sliding doors don't generate swing-arc warnings (they have no arc) but Flow Check still flags pieces blocking the slide path.
What's the difference between a pivot door and a hinged door?
Hinged doors rotate about the panel's edge (the hinge side). Pivot doors rotate about an offset point on the top and bottom of the panel (typically 1/4 of the panel width from the leading edge). The result: pivot doors swing differently — the leading edge moves further than a hinged door's leading edge for the same opening angle, and the trailing edge swings back partway. Pivot doors are used for large, heavy, or signature entry doors where the offset mechanism is more reliable than hinges and where the unusual swing pattern is part of the design. Room Sketch 3D models pivot doors as standard hinged doors in floor plan; the difference is visual only in 3D.
Can I make a Dutch door in Room Sketch 3D?
Currently, Dutch doors (hinged doors split horizontally so the top opens independently) are modeled as standard hinged doors. The split is a visual detail not represented in the 3D model. Note the split in the design name (e.g., 'Nursery — Dutch door') so the intent is preserved.
