Whether you're dreaming about having a brand-new, pristine pool installed in your backyard or yous already have your oasis in place, being able to measure out the size of your pool is bones knowledge every pool owner needs to know. The size of your pool dictates the size and type of many unlike support systems vital to maintaining a sparkling, well-functioning puddle, and how much information technology volition price to get a pool cleaning service.

In this post, nosotros'll cover several aspects of pool measurements and then you'll always have the perfect set of dimensions to brand sure your pool'south equipment and accessories are the right size for the job.

Measuring Pool Size 101

Knowing your swimming pool'southward size is really two different measurements. One is the physical dimensions of the puddle while the other is how many gallons of water the pool tin can agree.

With these measurements in hand, yous'll exist able to become the correct size pool pump, heater, filter, and other accessories like a cover. Without accurate measurements, yous can be left getting something either too big or too small to practise the job correct.

How to Measure Puddle Size by Expanse

You'll need to take measurements of the length and width of your puddle in order to find its area. If your puddle is a standard shape like a rectangle, this is straightforward. As an instance, an olympic-size swimming pool has a standard size with a length of fifty meters and a width of 25 meters. Multiplying the length times the width, or 50m x 25m, yields a full surface surface area of 1,250 foursquare meters.

A great many pools, nonetheless, have steps, curves, or other irregular shapes that really extend past the main body of the pool. For any of these sections, you'll need a slightly modified approach to finding the total overall area called the AB measurement.

Using the AB Measurement Method to Go Pool Size

This measurement requires two points, A and B. Mark on the deck of the pool at to the lowest degree 4' out from the border with a line straight between these points.
Looking directly at your pool, you'll desire to make sure bespeak A is to the left of signal B. The line between these points should non extend across the pool itself. This puts the AB line at somewhere effectually 66% of the length.
At the midway point betwixt A and B, measure how far the altitude is to the pool's edge to form a triangle.
From the triangle's point, you'll want to move clockwise and make a second point around 3 feet away and continue doing so every 3 feet.
From each of these new points, you'll need to take a measurement back to both points A and B, respectively. If you number your points, your measurements might look something similar "A1 = 5.five feet", significant from point A to the tip of the first triangle signal yous fabricated, "i", is a distance of five.5 feet.
Y'all'll demand to continue this measurement all the way effectually the pool for both A and B points.
Finally, accept at least four measurements diagonally from a few of these numbered tips.

All of these measurements are important in getting a custom pool cover created. Information technology's also a expert idea to accept pictures and even draw a scaled sketch of how you took your measurements so that the comprehend'southward manufacturer can go it right for purposes of an initial crude gauge.

How to Measure Pool Size in Gallons

Calculating how much h2o your puddle holds is vital for knowing what size maintenance systems are needed. At that place are several basic formulas our pool pros utilize to calculate how much water a pool tin can hold, depending on the shape of the pool.

Rectangle Pools

For a rectangular-shaped pool, utilize the formula length x width x boilerplate depth ten vii.48. Length times width provides surface area, and multiplying that past an average depth provides volume in cubic feet. With seven.48 gallons equaling 1 cubic foot, you use that as your multiplier to find out how many gallons of water your puddle holds. For example, if you have a 15' x 30' pool, with an boilerplate depth of 5', your calculation would be 15 ten 30 x five 10 7.48 = 16,830 gallons of water.

Circular Pools

If you lot take a round-shaped pool, the equation starts with π r 2 . Consider a 4'-deep pool with 10' bore and a radius of 5'. Your figure would expect like three.14 x 5 2 = 78.5 of surface area ten iv' = 314 sq ft. x 7.48 = 2,349 gallons of water.

Oval-Shaped Pools

Oval pools follow the formula of length 10 width x average depth x 5.9. For a 15' x 30' puddle with an boilerplate depth of five', your equation would be - 15 x thirty x 5 x v.nine = 13,275 gallons of water.

How to Measure out Puddle Size for Cover

When y'all accept a regular shape like our olympic pool in the example above, getting a encompass to lucifer is fairly straightforward. Simply plug in your length and width and yous should exist able to notice a standard size puddle embrace. When your pool is an irregular shape, you'll demand to follow the steps we outlined to get the AB measurement for puddle size. This method will provide the measurements needed to get a custom puddle cover for your pool'southward unique shape.

What Size Pool Pump Do I Demand?

The size of the pump needed for your puddle is based on several factors, some of which follow government standards for safety and hygiene. The size of your pool's pipes, how many right-angle bends are in the pipe, vertical lift, and even the altitude from the pump to the pool are all variables that need to be accounted for. These variables help to produce a figure known as caput loss. Your pump will need to produce a minimum flow charge per unit in guild to come across sanitation requirements.

To get this figure, y'all'll need to look up the building code in your expanse as the requirements can differ. For example, Florida Building Code R4101.20 dictates that "the unabridged design of matched components must have pregnant chapters to provide a consummate turnover of pool water inside 12 hours or less".

To get the minimum flow charge per unit, you'd accept your volume in gallons and divide it by the specified turnover charge per unit in minutes. If your pool holds 16,830 gallons of water and we use 12 hours to go 720 minutes, your formula would be 16,830 ÷ 720 minutes = 23.375 gallons per infinitesimal is the minimum menstruum rate required for your pool pump.

Pro Tip: If your pool requires a pump with at least 23.375 GPM of period rate, it's mostly best to get with a slightly bigger pump in order to recoup when components similar the filter go muddied and the flow rate is impeded.

How to Size Pool Heaters Like a Pro

Solar heaters, electrical pool heaters, gas—oh my? Every bit with most things when it comes to pools, y'all'll take a pick of a diversity of puddle heaters and the size of the heater depends on the type you choose. Each has its own advantages and disadvantages just all rely on how apace they can rut your pool as indicated by their British Thermal Unit (BTU) rating.

A general rule is to accept at least fifty,000 BTUs per 10,000 gallons of water. So with a 30,000-gallon pool, you'd want 150,000 BTUs.

How to Size Pool Filters for Any Size Pool

In that location are several different types of pool filters available that all offering unique advantages. There'south generally not a all-time filter for every application but there are certainly pros and cons. Like your dwelling house's air conditioning unit filter, pool filters differ in their level of operation.

Some filters will remove smaller particles, others are easier to clean or install, some are more expensive, etc. The virtually important thing to call back is to at least get the minimum requirement met based on the flow rate and filtration rate. The max filtration rate is set based on the filter media blazon such as sand filters or cartridge filters.

Every bit a full general example, if you want a rapid sand filter with a max filtration charge per unit of 3 and you lot have a 90 GPM puddle pump, yous'd split 90 by 3 to get 30 square feet as the minimum size filter to do the job. As with pumps, information technology's always a practiced idea to default to a size up in order to keep your pool its cleanest.
