How To Choose the Right Pool Size
The Best Pool Size for You

Are you looking for the ideal pool size for your family, apartment, or institute? Below are some factors you should consider to construct the perfect pool.

1. Number of People

The higher the number of people, the more gallons of water you need; hence the larger the pool. When building recreational pools for families, professionals recommend 18 ft by 36 ft for a family of six and 16 ft by 32 ft for a family of below six.

Once you decide on the family pool size, you should also ensure that the construction includes a shallow and deep end for children’s safety. This will allow you and your loved ones to have an immersive experience!

2. Affordability

The cost of building a pool should match your budget as you don’t want to strain or leave the construction halfway. Depending on the type and size of pool you build, you can spend between $28,000 to $55,000 or even above, depending on the design and accessories you will be using.

Typically, an in-ground pool is more expensive than an above-ground pool. Reason? Inground pools require many construction activities like excavation, unlike above-ground, which are often ready-made and only require installation services.

Larger pools also demand more resources and labor, making them expensive. For instance, an Olympic-size swimming pool is the largest, measuring 25 meters by 50 meters (1250 meters squared). Such a pool will require a lot of construction materials compared to standard 25-yard pools.

As a result, you must evaluate whether you can afford to build an Olympic swimming pool or a smaller one before starting the construction process.

3. Pool Type

Whether you prefer traditional or infinity pools, the right pool size should meet your needs. You can match the popular size in the market with the purpose of your pool. For example, if you are setting up a residential swimming pool, you will need plenty of space to accommodate many people.

However, private swimming pools require less space as they are meant to hold only a few people. These pool types are less expensive and take a short time to construct.

4. Maintenance Pool Service

Swimming pools have recurrent costs due to maintenance services. For instance, the chlorinated water in public pools should be monitored and regulated consistently. Hence, you should build a pool size that is easy to maintain to ensure it functions efficiently.

Suppose you calculate the maintenance cost of an Olympic pool and realize it’s way above your budget; you can always go for an affordable option like a 20 x 40-foot pool. This will eliminate financial strain and serve the purpose.

5. Pool Design

The ideal pool size should accommodate different design options, including oval, True-L, rectangular, and Kidney pool designs. In addition, it should allow for easy customization of the private pools. Some of the best above-ground swimming pools that provide this option include Vinyl pools and fiberglass.

Some pool designs enhance your luxurious space including infinity pools and ocean pools. While expensive, they offer exclusive features and an exhilarating experience as you plunge your body into the cool or heated pool!

6. State Regulations and Requirements

The right pool size for you should not cause issues such as overflowing or splashing, leading to conflicts with the neighbors. Hence, you may be required to leave around 4 to 5 ft from your property line.

Your pool size should also follow all the requirements, including assessing the underground utilities so as not to tamper with them. You can consult the government officials for guidance on the same, especially if you prefer underground pools.

6. Backyard Space

How big or small is your backyard space?

Your backyard size determines the pool size you will set up or construct. If your backyard space is small, professionals recommend you construct a swimming pool measuring 14 ft by 25 ft. This will allow you and your loved ones to chill, although it’s not large enough to accommodate more people.

If your garden space is larger, you can choose from the following dimensions;

  • 14 ft x 28 ft
    4.3 m x 8.6 m
  • 16 ft x 32 ft
    4.9 m x 9.8 m
  • 18 ft x 36 ft
    5.5 m x 11.0 m
  • 20 ft x 40 ft
    6.1 m x 12.2 m
  • 22 ft x 44 ft
    6.7 m x 13.4 m
