Whenever you get pool supplies, the instructions say x ounces per 1,000 gallons or something similar. So how many gallons of water does my swimming pool hold?

There are a lot of sites on the internet that tell you how to work out your pool volume. These easy to use pool volume calculators from the Pool Wizard make life so much easier.

You just put in the measurements and it spits out the answer. I tested it out and it consistently gives ‘clean’ results to the nearest 100 gallons. I found this very nifty, after all, who wants a result like 11,489 gallons. It seems unwieldy and unnecessary to have such an accurate result as opposed to 11,500 gallons, which is just as good when it comes to swimming pool volume and chemical dosing.

The Pool Wizard site have also made provision for those who use metric values. You put in the measurements in meters and it gives metric pool volume results (in cubic meters) as well as the conversion into gallons.

I think the volumes are given in US gallons, though they do not say. Perhaps I’ll send them a note and get them to confirm (or deny) this.

    Thanks for pointing this oversight out to me Larry. The pool water volumes are all given in US gallons and I have had the pages updated to reflect this information.

    I write the capacity on the inside of the control box with a black permanent marker. This is good for people like me that seem to forget things easily.
    What were we talking about?

    A simple pool volume measurement tool we have used is length x width x average depth x 7.5. This will give you your pool volume.

    Excellent website, swimming pool calculations are not always as simple as we’d like to think. Variation in depths and bespoke requests can have an effect on swimming pool volume water.
