Required Furniture Clearances
Use these standard US clearances when sketching a layout. Skip them and even technically-fitting furniture will feel cramped.
| Situation | Clearance | Why |
|---|---|---|
| Primary walkway | 36 in (90 cm) | Two people can pass |
| Secondary walkway | 24 in (60 cm) | One person, no pets |
| Coffee table to sofa | 14-18 in (35-45 cm) | Reach drinks, leg room |
| Dining chair pulled out | 36 in (90 cm) | Stand up, walk behind |
| Bed side clearance | 24 in (60 cm) | Make the bed, walk around |
| Desk chair pull-back | 36 in (90 cm) | Roll back to stand |
| TV to seating | 7-8 ft per 50 in | Comfortable viewing |
Essential Measurements
Measure room length, width, and ceiling height. Note every window (width, height, sill height from floor). Measure every doorway with swing direction. Capture fireplaces, columns, radiators. Critically, measure the entire delivery path from the front door to the destination room.
Measuring with AI Photo Tools
No tape measure? AI tools estimate room dimensions from a corner photo. Include a doorway in frame so the AI can use the standard 80 in (203 cm) door height as a reference. Accuracy is within 5-10%, fine for first-pass planning. Confirm with a tape before clicking Buy.
Easy-to-Forget Details
Outlet locations decide TV and lamp placement. Baseboards push furniture 0.5-1 in away from the wall. Closet and room doors must still swing open. Radiators and heating vents need clearance for airflow.
Make a Quick Floor Plan
Sketch the room on graph paper, one square per foot. Mark door arcs, windows, outlets. Cut paper rectangles to scale for the furniture you are considering and move them around. Ten minutes here prevents a $1,000 mistake. Free apps like Magicplan or RoomScan do the same digitally.

Can I measure a room with my iPhone?+
Yes. The built-in iPhone Measure app uses the LiDAR sensor on Pro models for accurate room scans. Magicplan and Scale to Grams Measure Room work on any phone using AI photo estimation.
How tall are standard ceilings in the US?+
Standard US ceilings are 8 feet (244 cm). Newer homes often have 9 ft (274 cm) ceilings on the main floor. Vaulted ceilings can run 10-12 ft or higher.
How much clearance do I need around a queen bed?+
A queen bed (60x80 in / 152x203 cm) needs at least 24 inches (60 cm) of clearance on each side and 36 inches (90 cm) at the foot. So a queen needs roughly an 11x11 ft room minimum to feel comfortable.
