Flooring Calculator

Flooring is sold by the box but laid by the tile, and cuts eat into both. Enter the room size and tile size to get the honest shopping list: tiles for the area, a wastage allowance for cuts and breakage, whole boxes to buy, and the tile budget.

How it works

Room area = length × width. One tile covers (tile length × tile width) ÷ 144 square feet when tile sizes are in inches. Tiles = room area ÷ tile area, rounded up, then increased by your wastage percentage — 10% suits straight layouts; diagonal patterns need 15% or more. Boxes = tiles ÷ tiles per box, rounded up, because shops sell whole boxes. Labour, skirting and adhesive/grout are extra.
