Inground pool sizes: main points

Inground pool sizes. Before making a decision on the installation of a swimming pool, you’re probably concentrate on the main factor – size. Eventually, how can you imagine how a new swimming pool will look in your side yard without thinking on how much space it will occupy?

Actually, a pool can be of any size you wish. However, specific inground pool sizes tend to prevail. If you are uncertain how large of a pool you want, you should take a look at the most popular models.

The majority of rectangular pools are almost twice as long on one side as on the other, with a mean depth of about 6 feet. The most common swimming pool sizes are 10 x 20, 15 x 30, and 20 x 40.

And now, forget about this information, since the actual dimensions and form of your pool must be based on how you’re going to use the pool and what resources you must work with. Below are three main questions to ask yourself when choosing the pool size.

How will you use your pool? 

Ask yourself how you’re going to use your new pool. If you’re just going to lay next to the pool and occasionally take a dip to cool down, you won’t need a big pool. However, if you’re going to spend much time in the pool, it is reasonable to have additional space for moving around.

If you need a pool for exercise, there are two possible methods. The first one is to get a more elongated form or purchase a lap pool. The second option is to buy a smaller pool or probably a swim spa. Anyway, your pool must be deep enough.

Do you want a springboard? Well, in this case, you will need a very deep wide pool. Actually, because of risks the springboards pose, the smallest size for a pool with a springboard may be required by local legislation or your homeowners’ insurance.

The main thing is to build a pool, whose size is sufficient for the activities you want to do. Avoid wasting money or space on a pool that’s too chic or large. Thus, big families need a larger pool, while a couple without kids may need a smaller one.

Users of the pool

If the pool is used only by the adult people, you should choose a bigger depth to increase the amount of bathing area. For children, you may require a shallower option where they can just have fun.

Moreover, take into account the mobility of the pool users, and whether they can climb in and out with the help of a ladder. In case of accessibility is a problem, choose a shallow pool with steps or maybe a beach entry. Remember that if there’s a slope where the pool slowly transforms from one depth to another, that usually requires a longer pool.

Also, consider how many people will use the swimming. If your family is large, you will definitely need a bigger pool where everybody can have fun and do what they want. Remember that you may have guests who will come to swim in the pool and have a good time with you!

Surely, many things can change with time. Some family members may have kids, while others can grow old and stop being interested in the pool. However, you should try to plan in advance, since your pool may be there for decades.

The pool of your dreams may not be something you can really afford. While you may want to install a huge pool in your side yard, that’s unreal for the majority of people. Below are some of the most significant restrictions that can hold you back:


Size is one of the biggest factors in inground pool cost – if not the biggest. Your budget may limit how large your pool can be, or force you to make a tradeoff between the size and the quality of the materials you use.


Your swimming pool must fit in your side yard, ideally with sufficient space left over for other types of activities you like. And don’t forget that you’ll require additional space around the pool for a deck. That’s particularly true in case you want to spend more time resting and having fun next to the pool rather than bathing in it.

Maintenance time.

Bigger pools take more time to maintain. If you’re going to employ a pool service anyway, this may not mean much. But if you’re planning to clean the pool and control its chemical balance on your own, the size of the pool really matters.

Prefabricated restrictions.

If you purchase a pool kit or construct a fiberglass pool, you’ll be restricted to the sizes and forms provided by the manufacturers. Moreover, there’s a certain maximum size for fiberglass pool shells since they must be delivered untouched over public highways.

One last comment about the inground pool sizes

While the benefits of buying a bigger pool are obvious, the case with smaller models is less apparent. Apart from being less expensive, they’re also simpler to maintain (and the heating bills are lower). In addition, even if you have enough room in your side yard for a bigger pool, a smaller one leaves space for other types of activities.

That may seem unimportant at the beginning, but your swimming pool will take all your spare time. Therefore, we recommend you to choose smaller pools.
