How to Use the Tile Calculator
- 1 Enter tile dimensions in inches (e.g. 12" × 12", 24" × 24", 12" × 24").
- 2 Select your grout joint width (e.g. 1/8" standard).
- 3 Enter your room dimensions or total square footage, and click the green "Calculate Tiles ▶️" button.
Tile Calculator — Frequently Asked Questions
Q1 How do you calculate total tile square footage for a room or wall? ▾
Multiply length by width in feet to find total square footage. If using inches, calculate (Length in inches × Width in inches) / 144.
Q2 Why should you order 10% to 15% extra tile for waste? ▾
Extra tiles account for perimeter edge cuts, diagonal trimming, breakage during installation, and future replacement tiles from the same dye lot.
Q3 How does tile layout pattern affect tile wastage? ▾
Straight grid layouts require 10% waste, while diagonal (45-degree), herringbone, and chevron patterns require 15% to 20% waste due to corner diagonal cuts.
Q4 How do you calculate the number of individual tiles required? ▾
Divide total room square inches by the area of a single tile in square inches, then add your chosen waste percentage.
