The Timeless Classic
Subway tile is one of the most iconic, timeless, and cost-effective finishes in interior design. Originally created in 1904 for the subterranean walls of the New York City subway system, these simple, glossy white rectangles revolutionized public hygiene because they were incredibly easy to clean and reflected light beautifully.
Today, subway tile is the absolute standard for kitchen backsplashes and master bathroom shower surrounds.
While the tiles themselves are very cheap (often less than $1.00 per square foot), installing them is highly labor-intensive. Because they are small, a standard shower requires hundreds of individual tiles, and the classic "staggered" layout requires dozens of complex cuts.
The Running Bond (Staggered) Pattern
The defining characteristic of subway tile is not the tile itself, but the layout.
Subway tiles are traditionally laid in a Running Bond Pattern (often called a brick pattern or 50% offset). Instead of the vertical grout lines lining up perfectly from ceiling to floor (a grid pattern), every row is shifted sideways by exactly half the length of a tile.
The center of the tile above sits perfectly over the vertical grout joint of the two tiles below it.
Why Staggered Patterns Create Waste
When you reach the end of a wall in a standard grid pattern, you simply cut the tile to fit. However, in a staggered Running Bond pattern, every other row starts with a "half-tile." This means you must manually cut a tile exactly in half to begin the row.
If your wall has electrical outlets, plumbing valves, or windows, you will have to make dozens of complex "L-shaped" cuts to fit the small tiles around them. Because subway tiles are fragile ceramic, many of these delicate cuts will shatter the tile, rendering it useless.
How to Calculate Subway Tile
Calculating the number of subway tiles required requires finding the total square footage of the wall, finding the square footage of a single tile, and applying a heavy waste factor specifically for the staggered pattern.
The Formula
- Measure the total Length and Height of the wall in feet to find the Total Square Footage.
- Determine the physical dimensions of the tile in inches (The classic subway tile is 3 inches by 6 inches).
- Multiply the Tile Length × Tile Width to find the tile's area in square inches (e.g., 3 × 6 = 18 square inches).
- Divide that number by 144 to convert the tile's area into square feet (e.g., 18 ÷ 144 = 0.125 square feet per tile).
- Divide the Total Wall Square Footage by the tile's square footage to find the raw number of tiles needed.
- Add a 15% to 20% Waste Factor. (Because of the 50% offset pattern, subway tile requires drastically more cutting than large floor tiles).
Total Tiles = (Wall SqFt ÷ ((Tile Length × Width) ÷ 144)) × 1.15
Example Calculation
You are tiling a kitchen backsplash that is 10 feet long and 2 feet high. You are using standard 3" x 6" subway tiles.
- Wall Area:
10 × 2 = 20 square feet - Tile Area in SqFt:
(3 × 6) ÷ 144 = 0.125 sq ft per tile - Raw Tiles Needed:
20 ÷ 0.125 = 160 tiles - Add 15% Waste for the staggered cuts:
160 × 1.15 = 184 tiles
You should order 184 individual subway tiles. (These are usually sold in boxes of 80 to 100 tiles, so you would order 2 full boxes).
