How to Use the Tile Calculator
Using our tile square footage calculator is quick and easy. Just grab your tape measure and input your project details below to generate a complete custom material list:
Price Per Sq Ft ($): (Optional) Enter the cost of the tile per square foot to use this tool as a tile installation cost calculator.
Area Length (Feet): Enter the total length of the floor or wall space you plan to tile.
Area Width (Feet): Enter the total width (or height, if doing a wall/backsplash) of the space.
Tile Length (Inches): Input the length of a single tile you are using.
Tile Width (Inches): Input the width of a single tile you are using.
Introduction
Taking on a new tiling project can completely transform your kitchen, bathroom, or living space, but miscalculating your materials is a guaranteed way to ruin the weekend. Running out of tiles halfway through a backsplash means halting your progress, and guessing your grout or thinset needs usually results in unnecessary extra trips to the hardware store.
Our free tile calculator takes the stress and complex math out of your renovation. Whether you are using it as a floor tile estimator or planning a custom shower wall, this tool determines your exact square footage, automatically factors in the industry-standard 10% waste overage, and provides estimates for the thinset and grout you will need to get the job done right.
How Much Tile Do I Need?
If you want the general rule of thumb for figuring out your material needs without a tool, here is the basic formula every pro uses:
- Complex Patterns: If you are laying tile in a diagonal or herringbone pattern, bump that waste overage up to 15% (multiply your square footage by 1.15).
- Calculate the Square Footage: Multiply the length of the room by the width of the room (in feet). For example, a 10 ft by 12 ft room requires 120 square feet of tile.
- The 10% Rule: Always multiply your total square footage by 1.10. This adds a 10% overage to account for cuts, breaks, and awkward corners.
Frequently Asked Questions
Q. How do I calculate square feet for tile?
A. To calculate square feet for tile, simply measure the length and width of your installation area in feet, and multiply those two numbers together. Then, add 10% extra for waste. Our calculator handles this automatically.
Q. Can I use this as a shower tile calculator?
A. Absolutely! While it is highly popular as a floor tile estimator, the math works exactly the same for vertical spaces. Just measure the total width of your shower walls and the total height you want to tile, and enter them as your Area Length and Width.
Q. Does this tool work as a grout calculator?
A. Yes! Along with giving you your exact tile count, this tool estimates the bags of thinset mortar and grout you will need based on standard coverage rates for average-sized grout lines (usually 1/8″ to 1/4″).
