What it calculates
Estimate tile area, pieces and waste.
Estimate tile pieces from project area, tile size and waste.
Planning and estimating aid only. Verify project requirements, manufacturer instructions, adopted codes, permits, and field conditions before performing regulated work.
Use the field units shown below, then compare your result with the worked example. Round pieces to full packages only after checking pieces per box.
Estimate tile area, pieces and waste.
Project area plus waste is divided by the face area of one tile, then rounded up to whole pieces.
Layout, cuts, pattern matching and breakage may justify a larger waste allowance.
A 12 × 12-inch tile has 144 square inches, or 1 square foot, of nominal face area. A 100-square-foot surface with 10% waste needs 110 square feet of tile area, giving 110 pieces in this simple model.
Contractor tip: Round pieces to full packages only after checking pieces per box. Keep the same product batch where appearance matters, and plan separately for trim pieces and unusual cuts.
Tile length and width are inches, but project area is square feet. The tool uses nominal tile face area; it does not model grout joints, individual cuts, border patterns or box packaging.
Good practice: Compare the calculated quantity with plans, specifications, product packaging and current field conditions before purchasing material.
