Tile Calculator

Area to cover divided by the area of a single tile, with a waste allowance for cuts.

Layout pattern changes waste

A straight grid layout wastes the least tile; diagonal layouts, herringbone, and other patterns require more cuts and typically need a higher waste factor (15-20% instead of 10%).

Order extra for future repairs

Tile runs and dye lots change over time — buying a few extra tiles beyond your waste allowance means you'll have a matching replacement on hand if one ever cracks years down the road.

Diagonal layouts and intricate patterns need a higher waste factor to account for extra cuts.

What you entered

Area to cover (sq ft): 100Tile width (in): 12Tile height (in): 12Waste factor (%): 10

1
Area of one tile
(12 × 12) ÷ 144= 1 sq ft
2
Area to cover with 10% waste
100 × 1.10= 110 sq ft
3
Number of tiles
110 ÷ 1= 111 tiles

Result

Tiles needed: 111

Covering 100 sq ft with 12×12 in tiles needs about 111 tiles.
