Tile Calculator - Tile Count, Area & Waste
Enter the length and width of the area being tiled, then enter the face size of one tile. This avoids needing to calculate the square footage first.

Buying and sizing notes
- Buy extra from the same lot when possible. Matching tile later can be difficult.
How to use this estimate
What this includes
- Area dimensions
- tile size
- waste allowance
- rounded-up tile count
What it does not include
- thinset
- grout
- waterproofing
- backer board

Quick questions
How much extra tile should I order?
A 10% waste allowance is a common planning start, but complex layouts, diagonal patterns, niches, and specialty tile can require more.
Does this include grout or thinset?
No. This estimates tile count only. Setting materials, waterproofing, substrate prep, and trim pieces need separate planning.
Tile project reality check
This estimates tile count. A real tile project may also need substrate prep, waterproofing, setting materials, trim, layout labor, and grout details.
- backer board
- waterproofing
- thinset
- grout
- trim pieces
- layout
- waste
- niches
- edge profiles
