Floors & tiling
Floor & tile calculators
Every floor starts with one number, the area, and ends with a shopping list: boxes of tiles with the right spare for your layout, bags of grout and adhesive, packs of laminate or vinyl, a length of carpet, bags of screed and lengths of skirting. These calculators turn one into the other.
Measure in metres or in feet and inches — every box takes any unit. Each calculator shows its formula and a worked example, so you can check the numbers. Not sure about a tile or a pattern yet? Lay it out in the 3D tile visualizer, or try it on a photo of your own room.
