How many subway tiles for a 10 ft backsplash?
About 132 subway tiles (3×6 inch)
The short answer
A 10 ft long backsplash that is 18 inches tall covers 15 ft². Adding 10% for cuts gives 16.5 ft². A 3 × 6 inch subway tile covers 18 in², or 8 tiles per ft², so you need about 132 tiles. Take away any window or large gap in the run before you buy.
How it is worked out
- Area: 120 in × 18 in = 2,160 in² (15 ft²)
- Add 10% spare: 2,376 in²
- Divide by 18 in² per tile: 132 tiles
Other sizes and options
| Tile size (inches) | Tiles needed, 10% spare |
|---|---|
| 3×6 subway | 132 |
| 4×12 | 50 |
| 4×4 | 149 |
| 12×24 | 9 |
What can change the amount?
Grout joints make the real count slightly lower, which leaves you a little extra. Outlets and the range hood area usually still need cut tiles, so keep the 10% spare even when the wall has gaps.
