Kitchen Backsplash Calculator
Calculate the tile area needed for your kitchen backsplash.
Enter counter length and backsplash height to get exact material requirements.
Tile Area Needed
Backsplash tile area is the wall space between the countertop and the upper cabinets (or desired height).
Formula:
Tile Area = Total Length × Backsplash Height
Then subtract cutouts for windows, outlets, etc., and add waste.
Standard backsplash heights:
- Standard: 4 inches (10 cm) — just protects the wall
- Half backsplash: 9–12 inches (23–30 cm)
- Full backsplash: 18 inches (46 cm) — counter to upper cabinets
- Full wall: 36–48 inches (91–122 cm) — counter to ceiling
Tile waste allowance:
- Standard layout (brick/straight): Add 10%
- Diagonal layout: Add 15%
- Mosaic/complex pattern: Add 10–15%
Tile cost ranges (per sq ft):
- Ceramic: $1–15
- Porcelain: $3–20
- Glass: $5–30
- Natural stone: $7–40
- Mosaic sheets: $5–25
