To obtain the most accurate information, you may need to identify a few characteristics of the pool in order to determine its average size, and a trusted pool builder in Orange County can help.

It is important to note that there is no perfect swimming pool before delving into the dimensions and pool size of ordinary pools. This means that choosing the ideal swimming pool for your family is not a one-size-fits-all proposition.

Pool Builders in Orange County Answer – What is the Average Inground Pool Size?

American swimming pools are decreasing in size, and the average inground pool in California is 16 ft. x 32 ft. This is much smaller than the extravagant pool sizes of previous decades, primarily because budgets are tighter and backyard space is smaller.

Consumers today want a pool that makes the most of the available backyard space, with cost-effective maintenance over the long term. They’re willing to sacrifice size because smaller pools can meet their requirements—whether they want a spool, lap pool, diving pool, or free-form family pool.

Another important consideration in these times of climate change is the volume of water required to fill the pool. People are encouraged to reduce their water consumption as much as possible, and one way to do that is to have a smaller, shallower pool.

It takes 17,280 gallons of water to fill an average 16 ft. x 32 ft. rectangular pool with an average depth of 3.5 ft. That’s rather a lot, especially when you consider how often you’ll have to top it due to evaporation and exuberant swimming, splashing, and cannon balls.

Smaller volume pools are easier and cheaper to maintain than larger ones. They’re not as demanding on the filtration system—and they’re quicker and more efficient to heat. They’re also lighter on chemicals. As a result, their weekly and monthly maintenance costs are relatively low. The savings really add up when you look at the next five or ten years of regular use.

What is the Average Above-Ground Pool Size?

Above-ground pools are usually smaller than inground pools, but that doesn’t mean you don’t have to consider the same factors when installing the latter.

The average above-ground backyard pool is 15 ft. x 30 ft., and the depth is typically a uniform 4 ft. It’s very rare for above-ground pools to have a deep end because things get complicated as soon as you start excavating and leveling land—it all snowballs from there.

Average Size by Type of Pool

When you want a pool builder in Orange County to install an inground pool, the most important thing to consider is what you will use the pool for.

What is its purpose? Are you going to use it to cool off after a hard day and enjoy a sundowner before dinner? Are you going to use it for exercise? Will your whole family use it at the same time, playing games and generally being rowdy?

The types of pools play a critical role in working out costs.

Cocktail Pool

A cocktail pool only needs a little space, and its purpose is to entertain by plunging and not swimming. The average size is 7.5 ft. x 17.5 ft., while the average depth is 3ft. to 5 ft.

A luxury pool builder in Orange County can customize cocktail pool designs to suit your needs.


You could also get a spool, which is a spa and pool that allows you to cool off in summer and warm up in winter.

They’re great for people who want to avoid a pool dominating their backyard. Their average-sized pool is 20 ft. x 10 ft. Spools are very easy to maintain and cost comparatively little to maintain.

Lap Pool

A lap pool is perfect if you use your swimming pool for exercise. However, they need abundant backyard space, especially along the length but are much narrower than typical family pools or plunge pools.

It should be long enough to fulfill your exercise needs. At the least, you should get a lap pool that is 30 ft. x 8 ft. However, the average dimensions for a lap pool are a larger size at 10 ft. x 50 ft, with an average constant depth of 4 ft. to 5 ft.

If your backyard absolutely can’t accommodate that length, you might want to consider installing a jet or tether system that ensures you get a good workout.

Sports Pool

Alternatively, you can go for a sports pool, which is the same size as a family pool but is shallow at both ends and deep in the middle. This design is great for sports where players need to stand on opposite sides of the pool.

Diving Pool

A diving pool can be the average 16 ft. x 32 ft. pool but should be 9 ft deep. You could go up to 7.5 ft. at a pinch, but 9 ft. to 10 ft is ideal.

The extra pool depth is for safety because a dive off a diving board ends significantly deeper than a dive off the poolside. If a diving board doesn’t suit your style, you could ask your pool builder to install a jump rock or any other elevated position that gives you the height you need for a good dive.

Your Family and Your Pool

A typical size pool for an average family is 16 x 32 ft. Rectangle pools are perfect family pools. You can play games like pool volleyball, swim laps, and like back and relax on your swimming pool float.

You can have the traditional shallow and deep ends, with the shallow end being about 3 ft. and the deep end being 5 ft. or 5.5 ft.

Bigger families, or those that entertain a lot, should go for a bigger pool with an average size of 18 ft. x 36 ft to avoid feeling like they’re in a crowded pool.

Water slides are also quite a common feature on deep pools, but a custom pool builder can add a variety of features, including beach entry, that maximize your enjoyment around your swimming pool. 

Total Space Required for a Swimming Pool

When calculating the maximum space you have for a pool, don’t forget to include space for paving and decking. All pools need some paving around them. Paving can be made from various materials, but they should all be durable and slip-resistant. The paving around the pool should be at least 3 ft wide.

Pool decking is the outdoor space around the pool you use for throwing a pool party or lounging in the sun on a beautiful day. As a general rule, your pool deck should be at least big enough that all furniture is at least 30 inches from the edge of the pool, which is virtually the width of the paving.

Deck space can be as large or small as you want it. If you have a lot of outdoor parties, you need a lot of space. You need considerably less decking space if you just like to read on your lounger.
