Flooring Calculator
Flooring Calculator is a browser-based calculator tool on CalcToolsBase. Free, browser-based Flooring Calculator. Enter your values for an instant, clearly-labelled result - no signup, no uploads. To use it, enter your values and view the result directly in your browser — no signup and nothing to install.
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.

Technical notes
Flooring Calculator divides the floor area by the area of one tile, applies the waste % you enter, and rounds up to whole tiles.
Includes the waste % you enter; confirm coverage rates and material sizes with your supplier before ordering.
Nothing you type is uploaded — the calculation happens entirely on your device.
Worked example
A 5 m × 4 m room is 20 m². Adding 8% for cuts means ordering about 21.6 m² of flooring.
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.
