Calculating Pool Size
When chemicals or water are added to the pool, it is useful to know how many gallons the pool can hold. Since pool chemicals are added depending on how much water is in the pool, it's especially helpful to know the size.
Knowing the number of gallons a pool can hold isn't sufficient to start a chemical treatment plan for the pool, but it's a beginning. There are many other variables involved, such as the amount of sun the pool receives and how many contaminants are introduced by swimmers, blowing debris, etc. The quality of the water should also be considered and the type of material used to create the pool: i.e., concrete, vinyl-lined, or fiberglass.
Determining pool size
However, before chemicals are put into the pool, discovering the number of gallons the pool can hold is an excellent place to start. Many chemicals are added based on the number of gallons in the pool, which means it's necessary to know how many gallons the pool holds before knowing how much chemical to add.
Calculations by configuration
To determine the number of gallons in the pool, the only tool you need is a measuring tape. It also wouldn't hurt to get a helper to hold the free end of the measuring tape. What follows is a list of familiar pool shapes and the mathematical formulas to estimate the number of gallons in the pool. These formulas are for pools that have straight sides.
Round
If the pool is round, multiply the number of feet across by itself, then multiply the resulting number by the depth of the pool, then multiply by 5.9.
Rectangle
Multiply the length by the width using feet, then multiply that number by the average depth (also using feet). Multiply the answer by 7.5.
Oval
Multiply the longest length by the longest width, then multiply the answer by the average depth. Lastly, multiply by 5.9.
Unusual shapes should be calculated by determining smaller sections resembling the shapes listed above and then adding the totals together. As an example, if you have an L-shaped pool, it is calculated as two rectangles.
Hiring a pool company
Whether you choose to hire a professional instead of maintaining your pool yourself, these calculations are critical information for both keeping an eye on the maintenance and water usage. You can also get an idea of the pool's size if you choose to resurface or remodel the pool.
