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. Room Sketch 3D 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.

3. 3

   3. 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.

4. 4

   4. 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).

5. 5

   5. Ceiling heights

   8 feet by default. If your home has 9 or 10 foot ceilings, change it. If you have sloped or vaulted ceilings, use the per-vertex ceiling height editor.

6. 6

   6. Stairs (if any)

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

7. 7

   7. Smart Flow Check passes

   If Smart Flow Check shows red warnings, address them. At least understand them — sometimes warnings are intentional (e.g., narrow but acceptable walkway in a small room).

8. 8

   8. 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.

9. 9

   9. Room labels are reasonable

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

10. 10

    10. 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 Profile → Drawing Defaults.
