In stimulate to number out the suitable doses of chemistry for your pool, you require to identify how countless gallons the water the holds. To carry out that, you should use a ruler to measure your swimming pool to uncover out this four various numbers; Length, Width, typical depth and a multiplier the determines gallons.

You are watching: How many gallons in above ground pool

*

So here are the formulas to figure out exactly how much water is in your swimming pool:These formulas hold true for both Inground pools too as over ground pools.

Rectangular, Square or Free kind Pools:

Length x broad x average Depth x 7.5 = full gallons

For example: 16′ x 32′ x 4.5′ x 7.5 = 17,280 Gallons

Circular Pools:

Diameter x Diameter x typical Depth x 5.9 = complete gallons

For example: 18′ x 18′ x 4′ x 5.9 = 7,646 Gallons

Oval Pools:

Length x width x average Depth x 5.9 = total gallons

For example: 15′ x 30′ x 4′ x 5.9 = 10,620 Gallons

How to identify the mean Depth the a swimming Pool whereby the bottom slopes:

Below is a side-shot that the “typical” inground swimming pool that has actually a shallow end (see “D”), then a slope that leads right into the deep finish (see “C”).

*

First measure up the depth that “D”, the shallow end (usually all over from 3′ come 5′), and then measure up the depth that “C”, the deep end (usually anywhere between 6′ and 12′) . Then, add them together and also divide through 2. This is the mean depth of your pool.

For example, if your shallow end “D” is 3′, and your deep end “C” is 8′, this would be her formula because that the average Depth:

3′ + 8′ = 11′

11′ divided by 2 = 5.5.

Therefore, in this example, your average depth would certainly be 5 1/2 feet.
