Pool Water Volume calculator.
Estimate water for a specified rectangular, round or elliptical pool with linear depth variation.
Your inputs
Use measurements from your plan and properties from your chosen product. Any prefilled values are illustrative.
A clear estimate starts here.
Enter your dimensions and product details to see the quantity and purchase breakdown.
Formula and assumptions
How this calculation works.
The average-depth method assumes depth varies linearly across the plan area. Enter equal depths for a flat bottom. Steps, benches and other displacements are supplied separately.

Before you purchase
Use dimensions from your plan and properties from your chosen product. Any design spacing, section or fixing pattern must already be specified.
Nonlinear floors and complex free-form shapes need a separate geometric model. No chemicals or pool structure are specified.
