Quick answer
What does the Pool volume calculate?
How much water does a rectangular or average-depth pool hold? This calculator uses pool length, pool width, shallow depth, and deep depth to estimate pool water volume immediately in your browser.
With the values currently entered, the result is 64.9 yd³ — estimated pool volume. It also shows water volume, and average depth.
How to use the Pool volume
- Replace the example values with your own numbers.
- Review the result and supporting figures as they update automatically.
- Check the formula and assumptions before using the estimate for a decision.
Inputs used
- Pool length — entered in m
- Pool width — entered in m
- Shallow depth — entered in m
- Deep depth — entered in m
Pool volume formula
Length × width × average of shallow and deep depth
Assumptions
- The pool is approximately rectangular.
- Steps, slopes, and curved walls are not modeled.
Practical guide
Pool volume example and edge cases
How much water does a rectangular or average-depth pool hold? Let's use a concrete example, then look at the assumptions that can move the answer.
Example: A practical pool volume scenario
For this example, use pool length of 8 m, pool width of 4 m, shallow depth of 1.1 m, and deep depth of 2 m. These are starting values, so replace them with numbers that match your situation.
- Pool length
- 8 m
- Pool width
- 4 m
- Shallow depth
- 1.1 m
- Deep depth
- 2 m
Calculated result64.9 yd³estimated pool volume
Start with estimated pool volume. Then check water volume, and average depth to understand what sits behind the main result.
Example results use the default display profile. The calculator above follows your selected country and units.
How to read the result
- Read the main result first. The supporting figures for water volume, and average depth explain how the estimate is built.
- The method is Length × width × average of shallow and deep depth. Keep the units consistent and use values from the same time period.
Edge cases worth checking
When pool length is unusual
The pool is approximately rectangular. Double-check this input before relying on the result.
When deep depth is uncertain
Steps, slopes, and curved walls are not modeled. Run a lower and higher value to see a useful range.
What changes the result most
Pool length
Measure pool length with the same unit shown beside the input. Convert first if your source uses another unit.
Pool width
Measure pool width with the same unit shown beside the input. Convert first if your source uses another unit.
Shallow depth
Measure shallow depth with the same unit shown beside the input. Convert first if your source uses another unit.

Common mistakes
Check pool length
The pool is approximately rectangular. Make sure this matches the number you enter.
Keep deep depth consistent
Steps, slopes, and curved walls are not modeled. Use the same units and time period throughout the calculation.
Do not rely on one pool volume scenario
Run a cautious case and an optimistic case. The range is often more useful than one exact-looking number.
