Flooring Calculator
Flooring — flooring Calculator divides the floor area by the area of one tile, applies the waste % you enter, and rounds up to whole tiles. This page runs that same calculation on your numbers, in your browser: no signup, no uploads, nothing stored.
Give Flooring Calculator your floor area, tile length, tile width and waste % and it returns the number of tiles straight away. Built to estimate tiles for a floor, it runs entirely on your device.
Estimate only — not engineering or contractor advice. Quantities depend on the area, the product size and the waste % you enter, plus cuts, layout and openings, so confirm sizes with your supplier.
About this calculator
Flooring Calculator divides the floor area by the area of one tile, applies the waste % you enter, and rounds up to whole tiles. It matters before you buy: a clean volume estimate plus a waste allowance beats a guess every time. Here is the calculation on real numbers: A 5 m × 4 m room is 20 m². Adding 8% for cuts means ordering about 21.6 m² of flooring. For your own figures, use the calculator above — same method, your inputs, computed on-device.

FAQ
How is the waste allowance applied?
The number of tiles for the bare area is multiplied by one plus the waste percentage, then rounded up.
Does the Flooring Calculator keep my entries private?
Yes. The Flooring Calculator runs in your browser, so nothing you enter leaves your device.
How is a tile converted to square feet?
Tile length times tile width in inches is divided by 144 to get the area of one tile in square feet.
Why round the tile count up?
You cannot buy part of a tile, so the count is rounded up to cover the whole floor.
