How to check furniture fit
Compare the item footprint with the usable floor space.
Measure the room
Measure at the widest points and note doors, radiators and skirting boards that reduce usable space.
Measure the item
Use the widest dimensions including handles, legs and any reclining mechanism.
Set a clearance
Reserve 24–36 inches for walking, then check the doorway route before ordering.
What does this tool do?
Fitting furniture is a rectangle check with a comfort margin: the item has to clear the walls, and you still need space to walk and open doors. This calculator compares the item footprint with the room after subtracting a clearance band.
The Formula
Usable room = room dimensions − clearance; fits when item length ≤ usable length and item width ≤ usable widthFrequently Asked Questions
How much walking clearance do I need?
About 30 to 36 inches for main walkways and 24 inches for secondary paths. Leave more in front of wardrobes, drawers or appliances that open.
Does the diagonal check prove it will fit?
No. It is only an indicator for turning the item in the room. You still need to check door widths, stair turns, ceiling height and whether the item can be tipped on its side.
