Tile area and tile size

Measure the surface being tiled. For multiple walls or sections, calculate each separately or enter the combined length/width equivalent if you know it.

Buying and sizing notes

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

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.
