How to Calculate Pool Volume
What is Pool Volume?
A pool volume calculator computes the water capacity of a swimming pool in litres, gallons, or cubic metres. This is essential for dosing chemicals correctly — the right amount of chlorine depends entirely on water volume.
Step-by-Step Guide
- 1Rectangular pool: Length × Width × Average depth × 1,000 = litres
- 2Oval pool: Length × Width × π/4 × Average depth × 1,000
- 3Average depth = (shallow end depth + deep end depth) / 2
- 4For curved or irregular pools, break into rectangles or use the pool's own measurement
Worked Examples
Input
Pool 8m × 4m · avg depth 1.5m
Result
48,000 litres (48 m³)
8×4×1.5×1000 = 48,000 L
