TileMath - Tile Calculator

Built for tile jobs: feet-inch fraction keypad, instant tile & box counts, grout and thinset estimates, pattern previews, and shareable results.

Stop converting feet and inches into decimals just to figure out how many tiles you need. TileMath is a tile calculator built around the way measurements are actually written on a job site. Type 12' 3-1/2" directly with a purpose-built fraction keypad—no mental math, no decimal conversions, no mistakes. WHAT IT DOES • Tile count for any room — enter length and width, get the exact number of tiles • Multiple areas — add as many rooms or sections as the job needs • Boxes to buy — enter tiles per box and get whole-box quantities, rounded up • Cost estimate — set a price per tile or per box and see the total • Grout lines included — spacing is part of the math, not an afterthought • Waste allowance — 10% for straight lay, 15% for diagonal, 20% for herringbone, or set your own THE FRACTION KEYPAD Most calculators make you type 12.29 when the tape measure says 12' 3-1/2". TileMath doesn't. The keypad has feet, inches, and sixteenths right on it. Tap the fraction you see. Everything is displayed the same way you measured it. Prefer metric? Switch to meters, centimeters, and millimeters in Settings. The keypad changes with it. BUILT TO STAY OUT OF YOUR WAY • Fully offline — no internet connection required, ever • No ads • No account, no sign-up, no email • No data collection of any kind • History — past calculations are saved on your device so you can pull up a job you did last week FOR DIY renovators tiling a bathroom or kitchen. Tile setters and flooring contractors pricing a job. Anyone who has ever bought two boxes too few and had to drive back to the store. Measurements are shown in feet, inches and sixteenths, or in metric. Available in English, Chinese and Arabic.
