The calculation

Pieces = ceil(net area × allowance factor ÷ piece-and-joint module area). Packages round up separately.

  • Area estimate for a repeating size. Edge cuts and mixed-size patterns need a layout check.

    Measure with a little context

    How to use this tile calculator

    Enter one repeated tile size and the number of tiles per box. For mixed patterns, use the manufacturer’s area coverage instead.

    Diagonal layouts, niches and edge cuts affect waste. Adhesive, grout and waterproofing quantities are separate calculations.

    Pieces = ceil(net area × allowance factor ÷ piece-and-joint module area). Packages round up separately.

    A worked example

    With the example values shown below, the calculated result is 104 pieces. These are demonstration inputs, not installation specifications.

    View the example measurements
    • Length / circle diameter: 12 ft
    • Width: 8 ft
    • Piece length: 12 in
    • Piece width: 12 in
    • Joint width: 0.125 in
    • Pieces per package: 10
    • Extra allowance: 10 %

    From estimate to order

    Whole packages and pieces round up; measured lengths, areas and volumes keep full precision during calculation. Match the product dimensions and units to your quote, and check cuts, minimum orders and delivery before purchasing.

    Tile planning questions

    Can I calculate shower tiles with square footage?

    Measure each tiled surface and add those areas, excluding untiled openings once. This tool can count one repeated tile size for the combined area. Use separate estimates for walls, floors or accents with different sizes, and consider niches and edge cuts in the layout.

    Does the tile estimate include grout or adhesive?

    No. Grout depends on joint width, depth and product coverage; adhesive depends on the substrate, tile and application method. This result counts tiles and boxes, not waterproofing, installation labor or a complete tile system.
