How to Measure a Doorway for Furniture

Doorways are the #1 reason furniture gets sent back. The single biggest mistake is measuring the door slab width (the moving panel) instead of the clear opening (what you can actually fit through). They differ by 4-5 cm.

Perché misurare

• Sofa, bed, fridge clearance
• Door swing direction matters (some open inward, some outward)
• Narrow hallway corners may need the diagonal
• Removing the door from hinges gains 5 cm

Cosa ti serve

• iPhone with Ruler AR
• Length mode

Passo dopo passo

1. Clear opening width. Open the door 90°. From inside-of-door to opposite jamb. This is the ACTUAL passage width.
2. Clear opening height. Floor to top of frame opening. Watch for thresholds that reduce clearance.
3. Corridor / approach clearance. On either side of the doorway, measure the corridor width. Furniture has to turn at each corner.
4. Diagonal (if narrow). For tight L-shaped corridors: corridor width + corner depth = the max diagonal a piece can navigate. Use Material Calculator → Area to compute.

Consigli

• Remove the door from its hinges to gain another 4-5 cm
• Remove door handles too, they add 4 cm to the door thickness

Errori comuni

• Measuring door slab width instead of clear opening (4-5 cm difference)
• Forgetting the corridor, sofa enters door but won't turn
