Questions
Frequently asked questions
How much tile waste should I plan for?
For most projects, we recommend 15% waste factor. Use 10% for simple straight layouts with minimal cuts, and 20% for diagonal patterns, herringbone, or rooms with many corners and obstacles.
How do I calculate tile for walls?
Measure the width and height of each wall section you want to tile. Subtract any areas you won't tile (like windows or fixtures). Our calculator works for both floor and wall applications.
Should I buy extra tiles?
Yes! Always buy 10-20% extra for cuts, breakage, and future repairs. Tile dye lots can vary, so having matching tiles for repairs is important. Our calculator includes this waste factor.
How much grout do I need?
Grout coverage depends on tile size and joint width. Our calculator estimates approximately 25 lbs of grout per 200 sq ft for standard 1/8" joints. Larger joints or smaller tiles require more grout.
What is thinset and how much do I need?
Thinset is the adhesive mortar used to bond tiles to the substrate. Coverage is approximately 50 lbs per 100 sq ft using a 1/4" x 1/4" trowel. Larger tiles may require more thinset.

Guide
How to calculate tile for your project
Calculating the right amount of tile for your bathroom, kitchen, or flooring project is essential for avoiding costly mistakes. Order too little, and you risk delays and mismatched dye lots. Order too much, and you waste money on materials you don't need.
The Basic Tile Calculation Formula
The formula for calculating tile quantity is straightforward:
- Measure the area: Length × Width = Square footage
- Add waste factor: Square footage × (1 + waste percentage)
- Calculate tiles needed: Total area ÷ Area per tile
- Determine boxes needed: Total tiles ÷ Tiles per box (round up)
Don't Forget Additional Materials
Beyond the tiles themselves, you'll need grout, thinset mortar, and potentially backer board. Our calculator estimates these materials based on your square footage to help you budget for the complete project.
