Tile calculator
Turn floor or wall size into tiles, boxes, adhesive and grout, with a waste allowance.
Your measurements
How it's worked out
Tiles = area × (1 + waste) ÷ tile area. Adhesive is about 2.5–5.5 kg/m² depending on notch size. Grout kg/m² = (L + W) ÷ (L × W) × thickness × joint × 1.6.
Estimates only. Check sizes, coverage and quantities with your supplier, engineer or certifier before ordering. Standards references are a guide, not compliance advice.
