Be sure to measure out from the depth of your water, not the pinnacle of the wall or the depth of the pool. You desire to know how much water is in your pool, and it's probably not filled upwardly to the top.

Notation: The calculator rounds up decimal points, which makes it easier to calculate chemical dosing. But the rounding isn't plenty to throw off your h2o chemical science calculations.

If you have a more complicated shaped puddle, y'all'll need to run a few other calculations. We embrace how to calculate the book of an irregular-shaped pool at the end of this guide.

Note: These are estimates. You'll ever get more authentic results if yous measure your pool yourself. And ever measure out the depth of your water, not the height of your wall.

By the way, if you lot're struggling with knowing which puddle chemicals to add together and when, be certain to bank check out our Pool Intendance Video Course. It'due south an easy-to-follow guide to help you keep your puddle clean and clear.

How to Calculate Pool Volume Step-By-Step

If you need to calculate the volume of an irregular-shaped puddle or you're notwithstanding feeling confused, bank check out our video that walks y'all through how to calculate the volume of water in your pool. Or go on reading for a complete walk-through on these calculations.

Pool Volume Calculation Basics

To become your pool's volume, you need to calculate your pool's surface area and average depth. And to exercise that, y'all'll need a few bones metrics:

Length (L)
Width (W)
Depth (D) or Height (H)
Diameter (d) (for round pools)
Radius (r) (for circular pools)
Pi (3.14 constant)

Multiply the length and width to get the surface expanse of a rectangular puddle. So throw in your puddle'due south depth and yous'll go bones volume calculation.

Another key role of your equation: one cubic human foot of water contains 7.five gallons. So in gild to figure out how many gallons your puddle holds, you lot'll multiply your terminal cubic foot measurement past seven.5 to discover the volume of your pool.

Let'southward see what this looks like with unlike pool shapes.

Rectangular Pool Book

How yous summate your book will depend on how the bottom of your pool is laid out.

Constant Depth

The formula for finding the book of a rectangular pool with one depth (no shallow or deep end) is 50 × W × D × 7.5 = V (in gallons).

For case, if your pond puddle is 32 feet long, sixteen anxiety wide, and iv feet deep:

32 × 16 × four × 7.5 = xv,360 gallons

Variable Depths with a Gradual Slope

If your rectangular pool has more than one depth (shallow terminate, deep end), you'll need to practise a fiddling more math. First, make up one's mind the pool's average depth. Add the shallow cease depth to the deep stop depth, and divide past 2.

Pool Calculator Rectangle

For instance, if your puddle's shallow end is 3 feet, and the deep cease is nine feet, the average depth is 6 anxiety.

Side by side, multiply your pool's length and width and so multiply that number by the average depth. Finally, multiply that effigy by 7.5 to calculate the volume of the pool in gallons.

For instance, if your pool is 32 feet long, sixteen anxiety broad, and has an boilerplate depth of 6 feet:

32 × 16 × vi × 7.5 = 23,040 gallons

Variable Depths with a Drib-Off

If your pool has a definitive drib between the shallow and deep ends, the average depth will exist different, fifty-fifty if the shallow end and deep end are still, for case, 3 feet and 9 feet, respectively.

Treat the shallow and deep ends as separate pools. This will permit you to employ the volume of each section using the constant depth formula.

In one case you lot take the volumes of both parts, simply add them together to determine the book for the whole pool.

Circular or Circular Pool Volume

The formula for finding the volume in gallons of a round pool is three.14 × r2 × D × vii.5 = Five (in gallons)

Start by measuring your puddle'south diameter, which is measured at its widest signal across (i.e. your pool'south length). And then divide the diameter by two to get the radius.

Pool Calculator Radius

Your radius squared is the radius multiplied by the radius. Finally, mensurate the pool'southward depth.

For example, if your pool's diameter is 18 feet, your radius is 9 feet, and your depth is 4 feet:

3.14 × (9 x 9) × four ten vii.v = 7630.2 gallons

I rregular-Shaped Pool Volume

If you accept an oval, kidney shape, or other irregular-shaped pool, y'all can still summate the volume. You'll merely have to do even more math.

The easiest way to summate an oddly shaped pool is to imagine it broken down into 2 or iii smaller, regularly shaped parts. Try to see smaller, individual squares, rectangles, or circles inside the larger, irregular shape.

Once you lot've mapped them out, measure each part. Then use the same formulae above to calculate the volume in each smaller section. Finally, add together all the volume figures together, and you'll have a pretty close approximation of the pool's total book.

When To Enquire a Professional to Measure Your Pool

If the swimming pool volume calculator or calculations don't work properly for you because yous have an unusual pool shape, or yous but want everything to be more accurate, inquire a pool professional to have the measurements and figure out the volume for y'all.

Retrieve, before you add whatsoever chemicals to your puddle h2o, y'all demand to know how many gallons of water are in your puddle. Knowing your pool volume is not only critical for adding the right corporeality of chemicals, it's absolutely necessary if y'all're installing a new pool pump, pool filter, or pool heater. And keep these calculations handy for time to come reference. You'll need them ofttimes as a puddle owner!
