This calculator is part of Calculate Wiki’s Construction Calculators collection.
What You’ll Need
- Area Length (ft)
- Area Width (ft)
- Tile Width (in)
- Tile Height (in)
- Waste Allowance (%)
Formula Used
Tile coverage (sq ft) = (Tile Width in × Tile Height in) ÷ 144
Tiles needed = (Area × (1 + Waste % ÷ 100)) ÷ Tile coverage
Example Calculation
Using example inputs — Area Length = 10 ft; Area Width = 10 ft; Tile Width = 12 in; Tile Height = 12 in; Waste Allowance = 10 % — the Tile Calculator returns:
| Value | Result |
|---|---|
| Area to cover | 100 sq ft |
| Coverage per tile | 1 sq ft |
| Tiles (with waste) | 111 |
111 tiles needed. Covers 100 sq ft using 12×12 in tiles.
