Pool Volume Calculator
Enter pool measurements in feet to estimate total water volume.
Enter the longest pool length.
Enter the widest pool width.
Enter water depth, not wall height.
For a flat bottom, enter the same depth twice.
Estimated Pool Volume
0
U.S. gallons
Formula: Length × Width × Average Depth × 7.48
Accuracy note: Kidney-shaped and irregular pools are estimates. For complex designs, divide the pool into smaller sections and add the section volumes together.
