Tile Calculator – How Much Tile Do You Need?
How to Calculate How Much Tile You Need
Before starting a tile installation project, it is important to calculate the correct amount of tile needed for your space. Whether you are installing kitchen backsplash tiles, bathroom wall tiles, shower tiles, or floor tiles, measuring the area accurately helps ensure you order enough material for the project.
At Tile & Mosaic Depot, we recommend calculating the total square footage of the installation area and ordering additional tile to account for cuts, waste, and future repairs.
Our product pages include a tile calculator tool, but understanding the basic calculation method can help you estimate tile quantities quickly.
Step 1: Measure the Area
Start by measuring the length and width of the area where tile will be installed.
For example:
Length: 10 feet
Width: 8 feet
Multiply the two measurements to calculate the square footage.
10 × 8 = 80 square feet
This means the area requires 80 square feet of tile coverage.
Step 2: Add Extra Tile for Waste
Professional installers recommend ordering 10–15% additional tile to account for:
• Tile cuts around edges and corners
• Breakage during installation
• Layout adjustments
• Future repairs or replacements
Example:
80 sq ft + 15% extra = 92 sq ft total tile needed
Ordering extra material ensures your project can be completed without running short of tile.
Step 3: Consider Tile Size and Packaging
Tiles are often sold in boxes or sheets, each covering a specific square footage.
For example:
• A porcelain tile box may cover 16 square feet
• Mosaic sheets often cover approximately 1 square foot per sheet
If your project requires 92 square feet, you would need approximately 6 boxes of tile if each box covers 16 square feet.
Always check the product page for exact coverage information.
Tile Calculation for Different Projects
Kitchen Backsplash Tile
Kitchen backsplashes usually require smaller amounts of tile compared to flooring projects. Measure the length and height of each backsplash section and calculate the total square footage.
Mosaic tiles are commonly used for backsplashes because they create decorative patterns and are easy to install on walls.

Bathroom Tile Projects
Bathrooms often require tile for both floors and walls. Shower walls and floors may require additional tile due to cuts around plumbing fixtures and drains.
It is especially important to order extra tile when installing natural stone tiles, since natural materials can vary in pattern and color.

Floor Tile Installations
For floor installations, measure the full length and width of the room and calculate the square footage. Larger rooms typically require more waste allowance due to layout adjustments and tile cutting.
Porcelain tiles are a popular choice for flooring because they are durable and resistant to moisture.
