Formula and method
Volume = length × width × (shallow depth + deep depth)/2. Multiply cubic meters by 1,000 for liters.
Worked example
An 8 m by 4 m pool sloping evenly from 1 m to 2 m deep contains approximately 48 m³ or 48,000 L.

Rectangular plan with a uniformly sloping bottom. Steps, shelves, curved walls and nonuniform depth changes alter volume. This tool does not calculate chemical doses.
How this was calculated
Average depth = (shallow depth + deep depth)/2.
Volume = length × width × average depth; multiply m³ by 1,000 for liters.
Frequently asked questions
Does it include steps and shelves?
No. Those features displace water and nonuniform slopes need separate sections. Use measured water volume when precision matters.
