How to Use the Pool Volume Calculator
- Select your pool shape (rectangular, circular, or oval).
- Enter the dimensions of your pool in feet or meters.
- Input the average depth of your pool.
- Click “Calculate” to get your pool’s volume in gallons or liters.
Understanding Pool Volume Calculations
The formula for calculating pool volume varies depending on the shape:
- Rectangular pools: Length x Width x Average Depth x 7.5 (for gallons)
- Circular pools: π x Radius² x Average Depth x 7.5
- Oval pools: Length x Width x Average Depth x 5.9
Our calculator does the math for you, ensuring accurate results every time.
Why Pool Volume Matters
Knowing your pool’s volume is essential for:
- Chemical Treatment: Proper dosage of chlorine, pH balancers, and other chemicals.
- Filtration: Determining the right size and run time for your pool pump.
- Heating: Calculating energy costs and selecting the appropriate heater size.
- Water Bills: Estimating the cost of filling or refilling your pool.
Tips for Accurate Measurements
- Measure the length and width at the water’s surface.
- For average depth, measure the shallow end, deep end, and middle, then divide by 3.
- For irregularly shaped pools, break the area into sections and calculate each separately.
Common Pool Sizes and Their Volumes
Here’s a quick reference for standard pool sizes:
| Pool Size (ft) | Average Depth (ft) | Volume (gallons) |
|---|---|---|
| 12 x 24 | 5 | 10,800 |
| 16 x 32 | 5 | 19,200 |
| 20 x 40 | 6 | 36,000 |
