Pool Waterline Tile and Coping Perimeter Takeoff
Waterline tile and coping around a pool perimeter.
Example
You enter
- Pool length (ft) 32
- Pool width (ft) 16
- Waterline tile length (in) 6
- Waterline tile courses 1
- Coping unit length (in) 12
- Waste allowance (%) 10
You get
- Pool perimeter 96 ft
- Waterline tiles 212
- Coping units 106
Details, formula, and sources
perimeter = 2 x (length + width); tiles = ceil(perimeter / tile length x courses x (1 + waste)); coping = ceil(perimeter / coping length x (1 + waste)). A 16 x 32 ft pool has a 96 ft perimeter, so one course of 6 in tile is 212 tiles (192 neat) and 12 in coping is 106 units (96 neat) at 10% waste; a second tile course doubles the tile to 423 while the coping holds. The perimeter is the rectangular case; a freeform pool is measured on the tape. Distinct from the water-volume pool-volume.
perimeter_ft = 2 x (length_ft + width_ft); waterline_tiles = ceil(perimeter_ft / (tile_length_in/12) x courses x (1 + waste_pct/100)); coping_units = ceil(perimeter_ft / (coping_length_in/12) x (1 + waste_pct/100)).
Pool perimeter-takeoff identity by name (perimeter from the rectangle; tile and coping counts over their unit lengths with waste); first-principles arithmetic.
The perimeter arithmetic is public first-principles; the tile size, course count, and coping unit come from the layout.
