Calculate subway tiles needed for backsplashes and walls. Enter area and tile size to get exact piece count, box quantity, and cost estimate.
Subway tiles are rectangular tiles traditionally sized 3”×6”, inspired by the tiles used in New York City subway stations in the early 1900s. Today, subway tiles are among the most popular choices for kitchen backsplashes, bathroom walls, and shower surrounds thanks to their timeless, clean look.
This subway tile calculator determines how many individual tiles you need based on the wall area and tile dimensions. Modern subway tiles come in many sizes beyond the classic 3”×6”, including 2”×4”, 4”×8”, 4”×12”, and 4”×16”. The staggered brick-pattern layout adds cutting waste at the edges, which this calculator accounts for.
Because subway tiles are small, you'll need many pieces per square foot. The calculator converts the total count to the number of boxes to purchase, making your shopping list straightforward.
Understanding this metric in quantitative terms allows construction professionals to compare design alternatives, evaluate cost-effectiveness, and select the optimal approach for each project.
Subway tiles are small, so even a modest 30 sq ft backsplash can require 240+ tiles. Counting individual tiles is error-prone. This calculator handles the math instantly and adds waste for the staggered layout cuts. Regular use of this calculation supports compliance with building codes and inspection requirements, helping projects proceed smoothly through the permitting and approval process.
Tile Area = (Width × Length) / 144 Tiles = ⌈(Area × (1 + Waste%/100)) / Tile Area⌉ Boxes = ⌈Tiles / Tiles per Box⌉
Result: 264 tiles (4 boxes)
Each 3”×6” tile covers 0.125 sq ft. With 10% waste: 30 × 1.10 = 33 sq ft. Tiles = ⌈33 / 0.125⌉ = 264 tiles. At 80 tiles per box: ⌈264 / 80⌉ = 4 boxes.
Subway tiles have been a design staple for over 100 years. Their simple rectangular shape and clean lines complement virtually any decor style, from traditional to contemporary. White subway tile remains the #1 choice for kitchen backsplashes in the United States.
Traditional: 3”×6”. Modern: 4”×8” or 4”×12”. Small format: 2”×4” or 2”×6” for detailed designs. Large: 4”×16” for a contemporary elongated look. The 2:1 length-to-width ratio is the defining characteristic.
Running bond (brick offset) is the classic. Stack bond creates a modern grid. Herringbone (V-pattern) is dramatic. Vertical stack bond makes ceilings look taller. Cross hatch alternates horizontal and vertical rows.
Ceramic is the most affordable and available. Glass subway tiles catch and reflect light beautifully. Natural stone (marble) subway tiles add luxury. Metal (stainless or copper) subway tiles create industrial accents. Porcelain subway tiles are denser and more water-resistant.
Each 3”×6” tile covers 0.125 sq ft (18 sq in). You need 8 tiles per square foot, not counting grout lines. With 1/16” grout joints, it's closer to 7.8 tiles per sq ft.
The classic 3”×6” remains the most popular. The 4”×8” size has gained popularity in recent years for a more modern, slightly larger look with fewer grout lines.
Running bond (brick pattern with 50% offset) is the classic. Stack bond (no offset) is modern. Herringbone is dramatic. One-third offset is a popular variation. Running bond is easiest to install.
Most subway tile looks best with 1/16” to 1/8” grout lines. Smaller grout lines give a cleaner, more modern look. Larger 3/16” joints create a more traditional appearance.
Basic white ceramic subway tile costs $0.15–$0.50 per tile ($1–$4/sq ft). Glass subway tile runs $5–$15/sq ft. Handmade or artisan subway tile can cost $15–$30/sq ft.
It's not ideal for floors. Most subway tiles are wall-rated (less durable). The small size creates many grout lines. For floors, use 12”×24” plank tiles that mimic the subway aesthetic.
