How to use it
A few inputs, one explainable answer.
- Measure the item at its widest fixed points.
- Measure clear doorway width and height, including stops and hardware.
- Check the approach path and pivot space even when the dimensions pass.
Method
How the estimate works
The item’s two smallest dimensions are compared with the clear door width and height in both orientations. A diagonal check indicates possible—but not guaranteed—pivot clearance.
Worked example
A 34 × 38 × 82 in sofa cannot pass upright through a 32 × 80 in opening, but may fit when rotated if the surrounding hall allows the pivot.
Assumptions & limits
What can change the result
- Use clear opening dimensions with the door fully open, not nominal door size.
- The calculator cannot model hallway turns, ceiling height, railings, or flexible cushions.
- Remove legs, doors, shelves, and packaging only when safely designed to do so.
Questions
Frequently asked questions
Should I use the door’s advertised size?
No. Measure the actual clear opening with the door open. Stops, hinges, handles, closers, and trim can reduce usable space.
What does possible with rotation mean?
The item’s cross-section may clear diagonally, but the room must also provide enough space to tilt and pivot it through the opening.
Can removing the door help?
It may add useful clearance, but only remove hinges or hardware if you can do so safely and reinstall them correctly.
