How to measure for tile
- Floor: area = length × width. Walls: sum each wall area you’ll tile.
- Subtract large openings only if you need a tighter estimate.
- Increase waste for diagonal layouts, patterns, and small-format tiles.
Assumptions to double-check
- Coverage per box varies by tile size and packaging—use label coverage.
- Patterns and many cuts can push waste beyond 10–15%.
- Mosaics and feature borders often require separate estimating.
Buying tips
- Buy extra from the same lot/dye batch for color consistency.
- Round up your waste factor for complex layouts or many corners.
- Keep a few spare tiles after installation for future repairs.
