Flooring & Tile calculators

Flooring, tile and underlay quantity and cost calculators.

Tile and Grout Calculator with Spacer Width UKEnter the tiled area in metres, tile dimensions and spacer width in millimetres, tile allowance, and the grout coverage printed for that exact tile and joint. Tiles and grout are rounded as separate purchases.
Flooring CalculatorEnter your room dimensions in metres to get the square metres of flooring to buy, the number of packs, and an editable cost estimate, with a wastage allowance for cuts and spares.

How these flooring & tile calculators work

Each calculator starts from site measurements in metres and millimetres, converts them with a tested formula, shows the exact quantity and your waste allowance as separate lines, then rounds up to the package or order unit you actually buy. Prices are optional and always entered by you, so the estimate reflects your supplier rather than a national average.
