About this calculator
16x32 is one of the most common in-ground pool sizes. This calculator defaults to that footprint with a 5-foot average depth and returns the total gallons of water needed to fill it, which is essential for sizing pumps, filters, and chemical dosing since almost every pool chemical is measured per thousand gallons.
Worked example
Using the values the calculator loads with:
Inputs
- Pool length: 32 ft
- Pool width: 16 ft
- Average depth: 5 ft
Results
- Total water volume: 19,149
- Total cubic feet: 2,560
What each field means
Inputs
- Pool length (ft)
- The pool length used in the calculation, measured in ft. Starts at 32 ft so you have a working example on load.
- Pool width (ft)
- The pool width used in the calculation, measured in ft. Starts at 16 ft so you have a working example on load.
- Average depth (ft)
- The average depth used in the calculation, measured in ft. Starts at 5 ft so you have a working example on load. Accepted range: 2–12 ft.
Results
- Total water volume
- Returned as a whole number and shown as the headline result. It recalculates instantly whenever you change an input, so you can compare scenarios without reloading.
- Total cubic feet
- Returned as a whole number. It recalculates instantly whenever you change an input, so you can compare scenarios without reloading.
FAQ
How many gallons is a 16x32 pool?
At a 5-foot average depth, about 19,148 gallons, which is the typical estimate used for chemical dosing on this popular in-ground pool size.
What if my pool has a deep end and shallow end?
Use the average of the two depths as the average depth input — for example a 3-foot shallow end and 7-foot deep end averages to 5 feet.
Why does gallon count matter for chemicals?
Chlorine, shock, and pH adjusters are all dosed per 10,000 gallons, so an inaccurate gallon figure leads directly to over- or under-treating the water.
Accuracy and limitations
- Estimates assume standard, average conditions — local rules, pricing, and materials vary.
- Results are rounded for readability; add a buffer before ordering, booking, or committing.
- Double-check anything with a real cost attached against a local quote.
