About the Furniture Fit Calculator
Check whether your furniture fits before you buy or move. Enter the room size and a list of pieces with their width, depth and height, and see how much floor they cover, how much space is left, whether each piece fits the room, and whether it can pass through your narrowest doorway.
It uses one unit for everything: centimetres, inches, metres or feet.
The calculation runs in your browser, so the numbers you enter are not uploaded or stored.

Floor coverage is the total of width × depth for all pieces divided by the room area. A piece fits if it fits in the room in either orientation. It passes a doorway if its smallest side is narrower than the opening.

Furniture Fit Calculator FAQ
How does the furniture fit calculator work?
Floor coverage is the total of width × depth for all pieces divided by the room area. A piece fits if it fits in the room in either orientation. It passes a doorway if its smallest side is narrower than the opening.
How much floor should stay free?
A common rule of thumb is to keep roughly 30–40% of the floor clear so people can move around comfortably. Treat it as a guide, since layout matters as much as total area.
Does the doorway check allow tilting?
It is a simple check using the smallest side. Tight corners, stairs and door frames can make a real delivery harder, and legs or doors can sometimes be removed.
Is this furniture fit calculator free and private?
Yes. It is free with no sign-up, and the calculation happens on your device, so your numbers are never sent to a server.
