Measurements

Tile worksheet

Start with the surface you measured; tile and package specifications remain product-specific inputs.

Project areas

Each rectangle may use its own supported unit. Curves, slopes, overlaps, and cutouts are not inferred.

Selected tile

Tile dimensions and coverage are product-specific. The allowance is your choice; this tool does not prescribe a universal percentage.

Optional package / box

Use the packaging printed for the product you selected. Package coverage is an alternate purchasing input; no package size is assumed.

Optional price

Cost uses whole tiles for a per-tile price, or whole packages for a per-package price.

Starting takeoff is ready.

Packages to purchase

9 packages

Whole package quantity is rounded upward after your selected allowance.

Based on one measured 12 ft × 10 ft project area.

  1. Add each measured rectangular project area.

    11.15 m²= 11.15 m²

  2. Calculate the coverage of one tile from the dimensions you entered.

    0.1858 m² per tile= 0.19 m² per tile

  3. Apply the extra material allowance you selected.

    11.15 m² × (1 + 10 ÷ 100) = 12.26 m²= 12.26 m²

  4. Divide the adjusted required area by coverage from one tile.

    12.26 m² ÷ 0.1858 m² per tile = 66 tiles= 66 tiles

  5. Round upward to whole tiles for a tile-level purchase.

    round up 66 tiles = 66 tiles= 66 tiles

  6. Convert the calculated tile requirement using tiles per package and round upward to whole packages.

    round up 8.25 packages = 9 packages= 9 packages

Assumptions & warnings

  • Tile dimensions: 12 in × 24 in · allowance: 10%
  • info: Tile dimensions, coverage, and package details are product-specific inputs. This calculator does not assume a universal tile or package size.
  • info: Extra material allowance is your project choice. Tile layout, diagonal patterns, cuts, breakage, and matching lots can affect it, but no universal allowance is applied.
  • warning: Planning-only material takeoff. It does not provide substrate, waterproofing, structural, installation, grout, code-compliance, or manufacturer-warranty advice.
  • info: The package purchasing quantity is rounded upward to whole packages.

Method

The engine sums user-entered rectangular project areas, determines single-tile coverage from user-entered dimensions or coverage, applies the selected allowance, rounds required tiles upward, then optionally rounds selected product packages upward.

Worked example

The starting worksheet measures 120 ft². With the selected 10% allowance and 12 in × 24 in tile, it needs 66 calculated tiles, 66 whole tiles, and 9 packages of eight.

Planning considerations

Tile layout, diagonal patterns, complex cuts, grout-joint dimensions, breakage, matching lots, and installer practices can change the quantity you choose to purchase. Confirm product coverage and package details before ordering.

Scope

This is a planning-only material takeoff. It does not provide substrate, waterproofing, structural, installation, grout, code-compliance, or manufacturer-warranty advice.
