Accurate tile estimation prevents the headache of running short mid-project or overspending on excess material. This calculator accounts for the waste that inevitably occurs from cuts along walls, around fixtures, and from breakage during installation. Always buy all your tile at once from the same lot to ensure consistent color matching.
Plan for 10% extra for standard straight-lay installations and 15-20% for diagonal or complex patterns. Unusually shaped rooms, large-format tiles, and patterned tiles may require even more waste allowance. Always round up when purchasing.
Measure the wall height and width in feet and use those as your room dimensions. Subtract the area of any windows or doors that won't be tiled. Add 10-15% waste for cuts around edges and fixtures.
Popular floor tile sizes include 12x12, 12x24, 18x18, and 24x24 inches. Common wall tile sizes are 3x6 (subway), 4x4, 4x12, and 6x6 inches. Mosaic tiles are typically 1x1 or 2x2 inches, sold in sheets.
