Accurate floor plan checklist

In this guide

1. 1

   1. Walls closed

   Every room should be enclosed by walls forming a complete polygon. No gaps where two walls don't meet. RoomSketch3D auto-detects rooms — if a room isn't detected, the walls aren't closed.

2. 2

   2. Wall lengths match reality

   Spot-check at least three wall lengths against your physical measurements. Pay attention to walls with alcoves, columns, or chimney breasts. To fix one, tap the wall on the plan and type its length (see Set an exact wall length).

3. 3

   3. Corners are square

   Open Layers in the toolbar above the plan and turn on Show corner angles. Every corner of the outline shows its angle, measured where the walls meet on the inside: square corners read 90° in green. The inside corner of an L-shaped plan reads 270°, which is correct. A corner like 88° or 92° usually means one wall length was typed or traced slightly wrong; retype the lengths, or use All 90° in Plan Settings → Layout → Outline Editor if every corner should be square.

4. 4

   4. Doors in the right place

   Each door should be on a real wall in the right position. Check swing direction and hinge side — left vs right hand matters.

5. 5

   5. Window positions

   Each window on the wall it's actually on, sized to the real window, positioned where the real window is (not centered if it's actually off-center).

6. 6

   6. Ceiling heights

   Set when you create the design (8 feet unless you picked another). If your home has 9 or 10 foot ceilings, change it in Plan Settings → Ceiling. For sloped or vaulted ceilings, add a Vaulted Ceiling from the Structural tools.

7. 7

   7. Stairs (if any)

   Rise matches floor-to-floor height. Shape (straight/L/U) matches the real staircase. Direction (up/down) correct.

8. 8

   8. Smart Flow Check passes

   If Smart Flow Check shows red warnings, address them. At least understand them — sometimes warnings are intentional (e.g., a rug you meant to put under the sofa).

9. 9

   9. Furniture fits in 3D walkthrough

   Switch to 3D and walk through the room. If anything feels wrong — head clearance, doorway angles, sightlines — it probably is.

10. 10

    10. Room labels are reasonable

    Auto-detected room names should match the use you intend. Rename if needed.

11. 11

    11. Units are correct

    If you're sharing with someone in the US, make sure the plan is in feet/inches. With someone in Europe — meters/centimeters. Check Settings → Measurements (from your account menu at the top right).
