How to Use This Calculator

Select your pool shape: 1 = rectangular, 2 = oval, or 3 = round/circular.
Enter the length and width in feet (or diameter for round pools).
Enter the average depth in feet — for variable-depth pools, average the shallow and deep ends.
Review Volume in Gallons and Volume in Cubic Feet as inputs for chemical dosing and heater sizing.
Use Fill Time to estimate how long to fill with a garden hose (typically 5–10 GPM flow).

How the result changes with Length

Pool Shape: 1 = Rectangle, 2 = Round, 3 = Oval.
Length: Length of the pool (or long axis for oval pools).
Width: Width of the pool (or short axis for oval pools).
Average Depth: Average depth = (shallow end + deep end) / 2.
Diameter (round pools): Diameter for round pools (ignored for rectangle/oval).
