In bespeak to number out the suitable doses of chemistry for her pool, you require to determine how countless gallons the water it holds. To execute that, you must use a leader to measure your swimming pool to find out these four different numbers; Length, Width, average depth and also a multiplier the determines gallons.

You are watching: How many gallons is a 18 x 48 pool

So below are the formulas to number out exactly how much water is in your swimming pool:These formulas hold true because that both Inground pools too as above ground pools.

Rectangular, Square or Free type Pools:

Length x broad x average Depth x 7.5 = complete 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 = total 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 recognize the average Depth the a swimming Pool whereby the bottom slopes:

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

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

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

3′ + 8′ = 11′

11′ split by 2 = 5.5.

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