Tile Calculator

Estimate whole tiles or boxes for one area, several areas, or a known total—with extra material shown separately.

What are you tiling?

How is your surface measured?

Measurement system

How will you buy the tile?

Actual tile or sheet length
Actual tile or sheet width

Use the actual manufacturer dimensions for the tile or mounted mosaic sheet. Box-coverage mode can work without dimensions.

The 10% starting allowance is editable. It can cover cuts, breakage, pattern matching, and spare tiles; complex layouts may need a different value.

Use the coverage printed by the manufacturer for the exact product and box. No universal box size is assumed.

Grout-joint width is not used in this estimate. Tile dimensions alone do not model a real layout, edge cuts, or joint distribution.

How it works

How your project area becomes a tile order.

We total the project surface, apply your extra-material allowance, then round up only the final tile or box purchase.

Rectangular surface

Measured area = length × width × quantity

Multiple-area mode adds the exact area of every row.

Extra material

Order area = measured area × (1 + allowance %)

The allowance is applied before any tile or box rounding.

Tile count

Tile equivalent = order area ÷ actual tile area

Count results appear only when tile or sheet dimensions are known.

Box count

Boxes = round up(order need ÷ box capacity)

Capacity can be entered as tiles per box or manufacturer coverage per box.

Before you buy

What this estimate assumes

  • Every entered project surface is rectangular, flat, and non-overlapping.
  • The allowance is a planning input—not a guaranteed loss rate. Adjust it for the layout, tile variation, cuts, pattern matching, breakage, and desired spares.
  • Actual manufacturer tile or mounted-sheet dimensions and box coverage are used; nominal sizes and package formats are not assumed.
  • Grout-joint width, layout direction, borders, mixed formats, and grout quantity are outside this MVP estimate.

Confirm the exact product label

Nominal tile sizes and box contents vary. Before purchasing, confirm the manufacturer’s actual tile or sheet dimensions, pieces per box, coverage per box, and installation guidance.

The 10% allowance is an editable planning default, not a product guarantee or a substitute for an installer’s layout and manufacturer instructions.
