How It Works
Kitchen backsplashes typically span from countertop to upper cabinets (about 18 inches). Subtract outlet and window cutouts for an accurate tile count.
The Formula
Net Area = (Length x Height) - Outlet Cutouts - Window Area
Variables
- Length — Total linear run of backsplash in feet
- Height — Distance from counter to cabinets (usually 18")
- Outlets — Each outlet/switch plate subtracts ~0.33 sq ft
Example
A 10 ft backsplash, 18" high with 3 outlets: 15 sq ft - 1 sq ft = 14 sq ft. With 3x6 subway tiles = ~112 tiles + 15% waste = 129 tiles.
Tips
- Subway tile (3x6) is the most popular backsplash choice for good reason — it is timeless.
- Order 15% extra for backsplashes due to many edge cuts.
- Use a tile leveling system for consistent grout lines.
- Peel-and-stick tiles are a budget alternative but do not last as long.
- Consider bringing the tile all the way to the ceiling behind the range for a dramatic look.
