Tile Calculator
Count tiles and boxes for floors, walls, and backsplashes. Box coverage from the label is used when you have it; otherwise tile size does the math.
Measurement system
Tile & waste assumptions
Tile size
Box details (optional)
Box coverage from the product label is the most accurate — when set, it overrides tile-size math for the box count.
For layout planning only — grout lines don't materially change how many tiles you need.
Waste allowance
%
10% suits straight layouts. Use 15%+ for diagonal or herringbone patterns and natural stone. Extra tiles also cover cuts, breakage, dye-lot matching, and future repairs — returns are harder than reorders.
Works for floors and walls — enter the two sides of the surface.
