Estimate tile for a room floor
Use the project size and tile size to get a first-pass count before ordering material.

Tile Calculator
Estimate project area, tile area, and tile count needed with a waste allowance.
Why this page exists
Tile planning gets much easier when project size, tile size, and waste are turned into one clear count estimate. This calculator helps visitors estimate how many tiles may be needed for a floor or wall project using straightforward area math.

Estimated tile count needed after comparing project area with tile area and adding the waste allowance entered.
Estimated tile count needed85
Project area154.0 sq ft
Tile area2.00 sq ft
Project area with waste169.4 sq ft
- A 14.0 ft by 11.0 ft project covers about 154.0 square feet.
- Each 12.0 in by 24.0 in tile covers about 2.00 square feet.
- After adding 10% for waste, the estimate comes to about 85 tiles needed.
This is a planning estimate. Real tile needs can vary with layout pattern, grout spacing, cuts, breakage, and whether edge pieces can be reused.

How it works
What the calculator is doing
Enter the project length and width to estimate the project area.
Enter the tile length and width so the calculator can estimate tile area.
Add a waste percentage to estimate how many tiles may be needed once cuts and breakage are considered.
Understanding your result
The tile count estimate is most useful as a planning guide because layout pattern, grout spacing, and breakage can all move the real count. The waste allowance helps make the estimate more realistic than area math alone.

Ways people use this tool
Example scenarios help turn a quick estimate into a more useful comparison or planning step.
Compare two tile sizes
Changing the tile dimensions can show how much the count changes with a different tile format.
Check a higher waste assumption
A more complex layout may justify a higher waste allowance, which can make a bigger difference than people expect.
FAQ
Common questions
How is tile count estimated here?
The calculator divides project area by tile area, then adds the waste percentage entered to estimate the number of tiles needed.
Why does waste matter so much?
Cuts, breakage, and layout changes can all raise the number of tiles needed above a simple square-foot match.
Does this include grout spacing?
No. This version focuses on a practical area-based estimate, so grout spacing and layout details are not modeled separately.
