THE MATH, EXPLAINED
How we calculate
(Length × width − excluded area) × (1 + waste allowance ÷ 100) ÷ coverage per box. Round up.
Before you buy
This is an area estimate, not a tile-by-tile layout. Large tiles, diagonal patterns, niches, and irregular surfaces may need a different allowance. Adhesive, grout, and leveling materials are not included.
