Setting wall and ceiling heights
Set the ceiling height for the whole floor, then give single walls their own height for half-walls and sloped ceilings — and see the result in 3D.
Wall height (which is also the ceiling height) defaults to 8 feet, the residential standard. Change it for the whole floor at once, or for one wall at a time. A ceiling that slopes one way comes from walls of different heights; a vaulted or cathedral ceiling has its own tool, Vaulted Ceiling.
Step by step
- 1
Set the ceiling height for the floor
Open Plan Settings and its Ceiling tab. Tap the height and type the new one (typically 8, 9 or 10 feet), then tap the check. It applies to the whole floor: every wall on this floor is set to that height. If you've already given some walls their own height, the app first asks Overwrite all wall heights?, because those heights are cleared too. So set the floor height first, then adjust single walls. You can undo it. Each floor of a multi-floor design has its own ceiling height.
Plan Settings → Ceiling: type the height for the whole floor. - 2
Per-wall height override
Select a specific wall. The Inspector shows its Height — 8 feet by default, with quick presets (9', 10', 11') or a custom value. Use this for half-walls, partial walls, or walls that step up/down.

Sloped and vaulted ceilings
There are no separate corner heights: where walls of different heights meet, the corner takes the lower one. So raising walls along one side gives a shed ceiling that slopes one way across the room (see ceiling heights and sloped roofs). For a vaulted, cathedral or pyramid ceiling with a ridge, use Build → Vaulted Ceiling and drag a rectangle over the area; set its Eave and Ridge heights in its settings (see vaulted ceilings).
Raising walls on one side makes the ceiling slope up to meet them: a shed ceiling, in 3D.
Tips
8 feet for standard residential
Old homes and tract houses. 9 feet for new construction first floor. 10+ for high-end or formal.
Common mistakes
Half-walls need a height, not a delete
For a pony or half wall, lower the wall's height (say to 42 in) — don't delete it. It stays in the plan as a real half-wall.
Dropping a wall below its openings
If a wall's height falls below the top of a door or window in it, the opening no longer fits and Flow Check flags it. Raise the wall or lower the opening.
Frequently asked questions
What's the standard residential ceiling height?
8 feet (most common). 9 feet for newer construction; 10+ for high-end.
Can I make a vaulted ceiling?
Yes, with Build → Vaulted Ceiling: drag a rectangle over the area, then set its Eave and Ridge heights (Cathedral, Angled or Pyramid). Different wall heights give only a one-way (shed) slope. See vaulted ceilings.
How do I make a half-wall?
Select the wall and lower its height — about 42 in for a pony wall. It stays in the plan as a real half-wall rather than being deleted.
Do wall heights show in 3D and elevation views?
Yes. The 3D view shows them, and the elevation views (the four outside faces of the building) show each wall at the height you set.
