Calculate number of tiles needed with waste factor
How Tile Calculation Works
Formula
Tiles = (Area ÷ Tile Size) × 1.10 (waste factor)
- 1Enter the area dimensions (length and width in feet).
- 2Enter the tile dimensions (width and height in inches).
- 3The calculator converts tile size to square feet.
- 4Floor area is divided by tile area to get the exact tile count.
- 510% waste factor is added for cuts, breakage, and future replacements.

Frequently Asked Questions
Why add 10% for waste?
Tiles need to be cut at edges and around obstacles. Some will break during cutting or installation. The 10% buffer ensures you don't run short — which could mean mismatched tiles from different dye lots.
What size tile should I use?
12×12 inch tiles are the most popular for floors. Large format tiles (24×24) make rooms look bigger but require very flat surfaces. Small tiles (4×4) are common for backsplashes.
Should I order extra tiles?
Yes, beyond the 10% waste factor, keep a few extra tiles stored for future repairs. Tile lots vary in shade, so matching later can be difficult.
