We are here to help you answer the question, “how big is a kiddie pool?”. We will help you find the right size for endless summer fun.

Types of Kiddie Pools

The two main types of kiddie pools are plastic and inflatable. Both are great options for introducing children to water play and swimming. Before you decide which size of pool you need, it is best to decide on the type.

Plastic Kiddie Pools

These are typically circular in shape and can come in varied sizes. The harder, more sturdy versions are always smaller for toddlers and babies. You can also get snapset pools which are slightly more flexible and larger in size. 

The smaller plastic tubs do not require any assembly and the snapset pools are easy to set up. These pools are affordable and not as fragile as the inflatable versions. Some do consider the plastic to be too hard.

Inflatable Kiddie Pools

These will have inflatable walls and come in varied shapes and sizes. These also come in bright colors and can have slides as well as other play accessories. 

The PVC construction is durable but lightweight, and these can be easily folded up for storage when deflated. The one drawback is that you have to blow them up which can be time consuming. 

It is advised to get a pump for the larger options. You also have to be careful that you do not pop the walls. Most will come with patch kits, but the walls are fragile.

How Big Is A Plastic Kiddie Pool

Typically, a plastic kiddie pool will be a minimum of 2 ½ feet in diameter for toddlers and babies. These small pools are designed to hold one child, maybe two, if they are both small.

There is not much wiggle room in these pools, but they are designed to get babies used to the water only. Grade-schoolers will want a medium size pool and once you get to larger pools at 8 feet in diameter, the adults can join in too. 

Depending on the age of your kids and how many people you want in the pool, there are different sizes of plastic kiddie pools available.

The information in the table below can help you decide what size may best accommodate your needs. The data provided are based on average pools within those size categories, to help you narrow your search. We also have a few top recommendations for you to start with.

How Many Gallons In A Kiddie Pool

Of the variety of kiddie pools available, there is a range in terms of capacity. Kiddie pools can be small through large and can accommodate one child or an entire family.

The larger you go, the more gallons you will have. If you are wondering how many gallons your kiddie pool holds, there is a simple calculation you can do to figure this out. To figure out the gallon capacity, you need to consider both the size and weight capacity of the pool.

Kiddie pools can hold between 30 and 300 gallons of water, depending on their size. Kiddie pools range in size, construction, and capacity, and most will hold anywhere between 100 and 250 gallons. There about 7.5 gallons of water per cubic foot.

The formula to calculate gallons will be:

Diameter x Diameter x Average Depth x 5.9 = Gallons

There are smaller pools available, but the average family typically goes with medium sized pools. If choosing a smaller kiddie pool, the calculation above will help you determine the gallon capacity.

The table below shows average pool dimensions of rectangular inflatable pools and the gallons they will hold.

Helpful Tips To Know How Big A Kiddie Pool Is

The size of the pool you get will depend on several factors. After choosing whether you want an inflatable or plastic kiddie pool, there are a few additional tips that can help you find the right size pool for your family.

  • Family Dynamics: You want to get a pool that matches the size of your family and the ages of your children. If you have younger children or toddlers, you want to get a smaller and more shallow pool until they know how to swim. If you have multiple children, you want to opt for a larger size so they can all play at the same time.
  • Details: Look at what the pool requires before you buy. Does it need a pump? Does it come with a repair kit? Can it be easily stored? Are there any accessories or attachments? Does it have good reviews?
  • Test First: When you first get the pool home, always perform a test. Inflatable pools can be damaged during packaging and transit. Plastic pools can get cracked. Make sure you check for any defects and fill with water to find any leaks before letting anyone play.
