How to Use This Calculator
- Enter the pool length and width in feet (interior pool dimensions).
- Select pool shape: 1 = rectangular, 2 = oval, 3 = freeform/kidney.
- Choose cover type: 1 = solar/bubble, 2 = mesh safety, 3 = solid safety, 4 = automatic retractable.
- Set the edge overlap in inches — 12 inches is the standard overhang on each side.
- Review Cover Area (sq ft) and Estimated Cost to budget for cover purchase.
- Note Deck Anchors and Monthly Water Saved to plan installation and understand evaporation savings.

How this is calculated
Worked example, using the default values
- Identify Input Parameters4 parametersPool length (ft) = 30, Pool width (ft) = 15, Pool shape (1=rect, 2=oval, 3=free) = 1, Cover type (1=solar, 2=mesh, 3=solid, 4=auto) = 2 = 5 input(s) provided
- Calculate Cover areaCover area = grossAreaSqFt * shapeFactor544 = 544
- Calculate Cover lengthCover length = poolLengthFt + 2 * overlapFt32 = 32
- Calculate Cover widthCover width = poolWidthFt + 2 * overlapFt17 = 17
