## Measure the Pool Length

If you want to know how to measure pool size, one of the most important aspects is measuring the length of the pool accurately. Itโs not as difficult as it sounds, and there are several ways to do so.

### Using a Measuring Tape

The first method for measuring the pool length is by using a measuring tape. This method works well for rectangular or square-shaped pools but can also be used for free-form or curved pools. Follow these steps:

- Begin at one end of the pool, placing the beginning end of the measuring tape on the edge of the waterline.
- Unroll the measuring tape across the width of the pool until the other side of the pool is reached.
- Record the measurement that corresponds exactly with the opposite edge of the waterline.
- Repeat this process once more to double-check your measurements.

Be sure to hold the measuring tape straight and avoid any kinks or curves in the tape when making your measurement as this will affect the accuracy of your calculations. Once you have measured both sides of the pool twice, you can average out the total length measurements to achieve an accurate pool length measurement.

### Using a Surveyor’s Wheel

A surveyor’s wheel may be especially helpful if you’re trying to measure a very large pool length quickly. The methodology is fairly simple should you choose to use this tool:

- Start at one end of the pool where the water meets its wall. Stand inside the pool close enough to the wall to ensure that your hand can hold the wheel steady against it without hitting the bottom of the pool.
- Roll the wheel along the length of the pool until you reach the other side and have marked where it overlaps with the starting point. Try your best to keep the wheel upright and straight so that your measurement is accurate.
- Record the distance measured, moving back any obstacles or chairs which might get in between for a precise survey.

A Surveyor’s Wheel can be easily operated by one person and provides quick measurements without requiring multiple people like measuring tape does. It also helps obtain more precise measurements than using human estimates or visual assessments would let you do as several factors can cause errors while using them.

“A good rule of thumb: The longer the pool, the more effort will be required to measure its size properly.” -Bob Stark, Pool Contractor

Itโs essential to check the accuracy of your measurements when learning how to measure pool size. If every measure taken seems accurate, we suggest checking center points/opposite edges again before accepting the final measurement because overlooking these small details creates significant differences in measurable values.

If you’re worried about matching two parallel lines and making sure they are perfectly straight, looking onto both sides with a friend might provide assistance and double-checks the readings. Never perform calculations based upon assumptions on a non-standardized structure like pools. While easier but risky if left uncorrected, assumptions may become hard-to-correct mistakes later on.

### The Final Word

Knowing how to measure pool size is important whether you’re building an entirely new pool or simply remodeling. So utilize either of the mentioned methods above, make spot-on decisions, place orders for necessary hardware materials accordingly, and enjoy the blue clear waters of your luxuriantly-sized swimming pool!

## Measure the Pool Width

### Using a Measuring Tape

If you want to measure the pool width, using a measuring tape is one of the easiest and most reliable ways. However, make sure that your measuring tape is at least 50 feet long since it may not be possible to get accurate measurements with shorter tapes.

To start, hold one end of the measuring tape on the far left side of the pool wall. Stretch the tape until it reaches the opposite side of the pool wall where it meets the coping. Record this measurement as you will need it later.

Next, turn the tape around and measure the distance between the two points again to ensure accuracy. Jot down the second measurement and compare it with the first one to make sure they match. In case they don’t, measure once more to confirm the correct measurement.

The average pool width ranges from 10-12 feet for rectangular pools, while those shaped in irregular forms range from 14-16 feet. Some oval-shaped pools can have lengths ranging from 16-20 feet.

### Using a Surveyor’s Wheel

A surveyorโs wheel (also known as a land-measuring wheel) is another excellent tool for measuring pool width accurately. It resembles a bicycle tire but has an odometer attached that measures distance traveled.

To use a surveyor’s wheel, roll it along the length of the swimming pool wall, i.e., starting from one side and moving towards the other end. You’ll need to note the reading when the wheel makes a complete circle and returns to its initial point. This reading represents the exact measurement of the pool width.

Besides pool width, a surveyorโs wheel also calculates area, perimeter, and curve measurements in other applications, making it a versatile tool for contractors and landscapers.

### Using a Laser Distance Measurer

If you want to measure the pool width quickly, using a laser distance measurer can be an excellent option. It’s compact, precise, fast and doesn’t require any physical input like measuring tapes and surveyor’s wheels.

To use this device, point its laser pointer at one end of the pool wall and click it. Then, move it across the length of the wall while taking readings as it moves along. Finally, match up all of your measurements, then add them together, and get the final measurement you need.

You’ll be surprised at how accurate the results are with this method. However if pools have poor lighting conditions outdoors, some models may lack proper accuracy and result in errors.

“Good tools take time to acquire, but the investment is well worth it.” -Unknown

Henceforth, these three ways can help you determine how to measure pool size(width). Each one has its advantages depending on your preference, purpose, and budget. Choose according to what suits your needs best. Good luck!

## Determine the Pool Depth

### Using a Depth Finder

If you want to get precise measurements of your pool’s depth, using a depth finder is the best approach. This device uses sound waves to calculate how far away objects are from it, and it can give you an accurate measurement of the depth of your swimming pool.

To use a depth finder accurately, you need to have someone helping you or be able to place it at one end of the pool. Position the device in the water and wait for it to give you a reading. If it has not already been calibrated with the water temperature, do that before taking readings. Once the device gives you a reading, record it and move on to take measurements at other spots around the pool. Repeat this process until you have readings from several areas within the pool. Doing so will ensure that you can determine average depth easily and account for any unevenness along the bottom of your pool.

“When calibrating a depth finder, always keep in mind the recommended method suggested by the manufacturer.” -Shawn Collins

### Using a Long Pole

Another way to measure the depth of your pool is by using a long pole. This technique works well for pools up to about six feet deep but can still be used for deeper pools if modifications like using longer poles are made.

All you need to do is attach a tape measure into a ring at the base of the long pole (make sure there is no slack in the tape when measuring!). Then, put the pole vertically down into the water while keeping the marked area on top level with the surface of the water. As soon as the pole hits the bottom, note the figure where the water level meets the tape. Do this several times from various locations in your swimming pool to get an average measurement.

Note: if you are using a pole that is not long enough, tilt the pool surface slightly towards the plant (opposite direction of the shallow end) for right measurements. Also important to note is that this method isn’t as accurate as using a depth finder; however, it will give you a good estimate of your pool’s maximum and minimum depths.

“Although people have been using measuring tools like these poles for years with great success, I would recommend checking in regularly or when having renovations to double-check their condition.” -Matthew Peterson

## Calculate the Pool Volume

Having a swimming pool in your backyard can be very rewarding during hot summers. However, maintaining it requires some effort and knowledge. Knowing the size of your pool is crucial when it comes to buying chemicals, choosing proper filtration systems, or adding water. But how do you measure a pool? This article will explain four different ways to calculate the pool volume.

### Using the Formula for Rectangular Pools

If your pool has a rectangular shape, calculating its volume is easy. Follow these simple steps:

- Measure the width of your pool at its widest point, usually one end.
- Measure the length of your pool from the same side where you measured the width.
- Determine the average depth by measuring the depth at the shallow end and deep end, then add them together and divide by two.
- Multiply the measurements you have made: Length x Width x Average Depth = Total volume.

“The formula works because it calculates the volume of a three-dimensional rectangular solid. In this case, the sides represent the width and length measurements, while the height represents the average depth.” -Swim University

### Using the Formula for Circular Pools

For circular pools, calculating their volume is slightly more complicated but still manageable. Follow these steps:

- Measure the diameter of your pool, which is the distance across the widest part, through the center.
- Determine the average depth as previously mentioned.
- Multiply ฯ (pi) by the radius squared by the average depth to arrive at its volume.

The radius of your pool is half the diameter. ฯ is a mathematical constant with an approximate value of 3.14.

“Calculating volume using this formula works because it calculates the volume of a three-dimensional sphere or cylinder.” -WikiHow

### Using the Formula for Freeform Pools

Freeform pools are those that have an irregular shape, such as kidney-shaped, L-shaped, or others. Calculating their volume can be challenging; however, there are two options:

- The first method involves dividing the pool into smaller sections and calculating them separately. Measure each section’s length, width, and depth, add up the volumes, and you’ll get the total pool volume.
- The second method requires taking multiple measurements at different points in the pool to estimate its average depth. Afterward, calculate the pool’s surface area by multiplying the length and width at various intervals (every meter, for instance) and averaging the results. Lastly, multiply the average depth measurement by the surface area result to obtain the pool volume.

“For freeform pools, precision is essential. It would help if you took extra care when making your calculations, so make sure all measurements are accurate before starting any math.” – Pool Calculator

### Using an Online Calculator

Estimating pool volume manually can be time-consuming and prone to human error. Alternatively, you can use one of many online tools available. The process usually entails selecting the shape of your pool, entering some dimensions, and voila! You will receive your pool volume calculation almost instantly.

“Online calculators significantly reduce the chance of errors in manual calculations and offer instant results. However, they may require an active internet connection, which could be problematic in remote locations.” -Blue Wave Products

To conclude, having a swimming pool in your backyard provides you with ample opportunities for entertainment and relaxation. However, maintaining it comes with the responsibility of knowing its dimensions. While we have provided various methods to measure pool size, please remember that precise measurements are crucial when making calculations for maintenance or renovation purposes.

## Consider the Shape of the Pool

If you’re planning to build a pool, or you simply want a better understanding of how large your existing pool is, it’s essential that you know how to measure its size accurately. One key factor in measuring the size of a pool is determining its shape. Pools come in all shapes and sizes, with some being more complicated than others.

### Calculating the Volume of a Kidney-Shaped Pool

Kidney-shaped pools are popular among homeowners, but their curvy shape can make them a bit trickier to measure than standard rectangular pools. To calculate the volume of a kidney-shaped pool, one should first break down the pool into two parts: a rectangle and a half-oval. By calculating the volume of each section separately, you can determine the overall volume of the entire pool.

A general rule for estimating pool water capacity is multiplying your poolโs length by its width, then by its average depth. Multiplying that result by 7.5 will give you the number of gallons your pool holds at 100% full.โ -Blue Science

To get started, measure the longest points of the oval within the pool—this may be marked on the pool itself if there is visible surrounding coping. Record this measurement as โLโ (in feet). Next, repeat for the shorter dimension running perpendicular to the longer one. This will give you โWโ (also measured in feet). Then, find the average depth of the pool from shallow floor area to deep end โ weโll call this โDโ. Finally, measure the length of the straight sides of the pool along the inner edge, record this as well.

Multiply the length by the width then multiply it again by D times 0.45, that gives you the rectangular volume. To calculate the half of an oval, multiply D x ((short diameter + long diameter)/4)^2 x 0.45.

Add this to the rectangular value and that’s your total pool capacity!

### Calculating the Volume of a L-Shaped Pool

L-shaped pools are another example of a more complex shape for measuring their size accurately. An L-shaped pool will require more complex calculations, as it is made up of multiple sections consisting of rectangles and triangles. It can be a headache to determine its size and may need the assistance of professionals.

“When calculating pool volume of these non-standard shapes (like kidney or L), consider bringing in a professional to assist. Calculations become much more complicated when there additional areas.” -R&R Pools

The best approach in calculating the volume of an L-shaped pool is to break down each portion into smaller regular shaped parts like squares, circles, or rectangles. These shapes have an easy formula to determine water capacity. For instance, take a rectangle section first, mark the length (L) and width (W) before marking the depth (D). Measure again from one of its adjacent sides of each triangle attached to the L shape โ marking this along with the length or base of the triangle (T).

Now, split those two triangles equaling the full side by taking T multiplied by W/2 and dividing by 2. Then add that number on both ends of the L-shapeโs total square footage. Finally, work out the math based on average depth. Follow similar steps if the other side is different.

**In conclusion,** no matter what type of pool shape you have, measuring its dimensions accurately is essential for maintenance purposes, installation of accurate cleaning equipment and properly dosing chemicals for its size. By taking the time to break down your pool into smaller shapes, it’s possible to measure its volume accurately and make sure that you have all the information necessary for proper maintenance.
