Tile Calculator
PopularEstimate tile count, boxes, square footage, waste factor, and flooring material cost for bathroom, kitchen, or any room renovation.
Planning a bathroom or kitchen renovation? Enter room dimensions, tile size, waste factor (10–20%), and price per square foot — get tile count, box quantity, total area, and material cost. One of the highest-intent home improvement searches before every remodel.
Diagonal layouts and complex patterns need 15–20% waste; straight lay uses 10%. The calculator rounds up to whole tiles and boxes so you do not run short mid-installation — nothing worse than a discontinued tile color halfway through a shower.
Works in feet/inches or meters/centimeters. Also useful for estimating laminate, vinyl plank, or any square-foot-priced flooring sold by the box or pallet.
Standard 12×12 in tiles: a 5×8 ft bathroom floor (40 sq ft) needs roughly 44 tiles at 10% waste. Larger format tiles (24×24) cover more area per piece but require more cuts on small rooms.
Buy one extra box for future repairs — store it in a dry place in case tiles are discontinued. Grout and thinset are separate; budget 10–15% of tile cost for setting materials.
Tile quantity, boxes, and flooring cost for your renovation.
Formula
Area = length × width · Tiles needed = (area ÷ tile area) × (1 + waste%) · Boxes = ceil(tiles ÷ tiles per box)
