Formula Used
  1. Rectangular floor area = Length × Width per row.
  2. Rectangular wall area = Length × Height per row.
  3. Perimeter wall area = Perimeter × Height per row.
  4. Curb top area = Curb Length × Top Width (if covered).
  5. Curb faces area = Curb Length × Height for front/back (if covered).
  6. Curb end caps = Top Width × Height × number of ends.
  7. Openings (doors, windows, niches) = Width × Height and subtracted.
  8. Module dimensions = (Tile Length + Grout) × (Tile Width + Grout).
  9. Module area = Module Length × Module Width (converted to area units).
  10. Raw tiles = Net Area ÷ Module Area.
  11. Total buffer % = Waste Allowance + Pattern Extra.
  12. Tiles incl. waste = ceil(Raw tiles × (1 + Buffer/100)).
  13. Boxes = ceil(Tiles incl. waste ÷ Tiles per Box).
  14. Curb trim edges = Sum selected edges; inside top edge reduced by drain length.
  15. Trim pieces = ceil(Edges × (1 + Trim Waste/100) ÷ Piece Length).

Notes: Linear drain typically runs along the inside edge of the curb; adjust drain length accordingly. Confirm site details for glass returns or specialty profiles.

How to Use
  1. Select Area Unit System and Tile/Joint Units.
  2. Add Areas (floor or wall mode), Openings, and optional Perimeter Walls.
  3. Set the Curb dimensions, covered faces, ends, and drain options.
  4. Enter tile size, grout, pattern, waste, and tiles per box.
  5. Use Edge Trim plus the curb edges to count pieces.
  6. Press Calculate, then export with Download CSV or Download PDF.

FAQs

Joints slightly reduce tiles needed because each module occupies more area. This tool approximates by adding the joint width to both tile dimensions.

Common projects use 5–10%. Complex layouts, diagonal patterns, or brittle materials may need 10–15%. You can also add a pattern extra from the dropdown.

Enter total wall perimeter and height for an enclosure. It multiplies perimeter by height, then subtracts openings like doors or windows if added separately.

Set curb length, height, and top width. Choose covered faces and edges to trim. If the drain runs inside the curb, subtract its length from the inside top trim.

Sum all edge lengths and apply trim waste. Divide by the length of a single trim piece and round up. Auto-from-areas assumes simple rectangles—confirm for complex layouts.

If a supplier quotes per square area, use the Net Area and apply your chosen buffer to order enough coverage.
