How to measure a room by counting floor tiles

No tape measure? The floor has one built in. Count the whole tiles, then say how much of the cut one is left.

The planner’s measuring screen: whole tiles counted along a wall, and the cut tile at each end.

Most homes in Nigeria have tiled floors, and a tile is a ruler you are standing on. A 60 × 60 cm tile — the commonest size — with its grout line is very close to 600 mm from one joint to the next. Count them and you have a length.

Count the whole tiles first

Stand at one wall and count the whole tiles in a straight line to the other. Do it along the wall with the front door, then along a side wall. Two counts give you the room's width and depth.

Then the cut tiles — this is the step that matters

Almost every room ends in a cut tile against the wall. Counting that cut piece as a whole tile is the single most common mistake, and it moves a wall by half a tile or more. So Urcrib asks, for each end: is the tile against the wall cut, and how much of it is left — a quarter, a half, three quarters, or you are not sure.

How sure is a tile count?

A tile count is good to about ±5%. That is less certain than a tape measure (±30 mm), and more certain than pacing it out in steps (±10%). The plan records which you used, and every size on it says how sure it is — so when a wardrobe is close to the edge, you are told to check with a tape before you buy.

Your tile size

Measure one tile's edge, including one grout line. If your tiles are not 60 × 60, choose the size on the measuring screen — 50, 45, 40 and 30 cm are all there.
