In stimulate to figure out the proper doses of chemistry for her pool, you require to identify how plenty of gallons the water the holds. To do that, you need to use a leader to measure up your swimming pool to discover out this four different numbers; Length, Width, average depth and also a multiplier that determines gallons.

You are watching: How many gallons in a 15 x 36 pool

So right here are the recipe to number out exactly how much water is in her swimming pool:These formulas hold true for both Inground pools as well as above ground pools.

Rectangular, Square or Free kind Pools:

Length x broad x median 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 mean 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 median Depth x 5.9 = total gallons

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

How to determine the median Depth the a swimming Pool where the bottom slopes:

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

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

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

3′ + 8′ = 11′

11′ split by 2 = 5.5.

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