How Deep Are Above Ground Pools & How to Build Them?

I know you’re thinking about to building above ground pool in your backyard. But how deep are they, and how do you build them? In this blog post, I will help you to understand the depths of the above ground pool and how you can build it by yourself. So without doing delay let’s start with this informative article.

How deep are above ground pools?

Generally, the depth of the above ground pool is between 3 and 8 feet, but it can be deeper. You may ask yourself, how deep your pool should be, think about what you’ll be using it for. If you just want to be cool in summer, will definitely be worth it. But if you’re looking to play games, a deeper pool will give you more space to move inside the pool.

Do you know? The depth of your above ground pool also depends on the height of the wall. The height of your pool taller means it is deeper. As I already mentioned, the average depth should be 3 to 8 feet. If you’re not sure about how what should be the depth of your pool, you can ask a professional for help. They will guide you about what depth is best for your needs and how to build.

Factors that can affect the depth

The depth of above ground pool depends on the shape, size, and wall height. It can differ as per your preference and the depth you want. The first factor that affects the depth of your pool is the shape. The round pool has a more gradual slope, so it will be shallower at the edges and deeper in the middle. Oval or rectangular pools may have a more consistent depth throughout.

The size of the pool can also impact its depth. Larger pools may be able to accommodate a greater range of depths, while smaller pools may have a more limited range. The height of the walls also affects the overall depth of the pool. Higher walls mean a deeper pool and vice versa.

How to measure the depth of an above-ground pool

Accurately measuring the depth of your above ground pool is important for safety reasons, I mentioned some tips for accurately measuring the depth of a pool. Before getting started, you should have a leveler handy so you can set up your measuring tools properly. You can use a laser leveler or a chalk line along the side of the pool to make sure that it’s perfectly vertical.

If you don’t have access to a laser leveler, then use a tape measure and yardstick instead. Place one end of the tape measure on one side of the pool and pull it all the way around until it reaches the opposite side. Hold down the second end with your hand as you measure so that it doesn’t move around too much while you’re trying to get an accurate reading on your yardstick.

Measure from multiple points if possible. It’s always better if you can measure from different points along each wall since this will give you an idea of how even they are throughout their entire length which is important when figuring out how much water each section contains.

The range of depths available

Most of you guys think that 8 ft is the best depth of your above-ground pool for swimming but it can be dangerous. In the USA, pools are generally 6 feet tall and I also recommend the same height. Pool depth for children or those who just want to cool off on a hot day should be 3-4 feet deep. I reached out to a pool maintenance expert and curate some data that can help you to understand what should be the measurement as per your requirement. So, here’s the recommended size, shape, and wall height for your above ground pools.

Please note that this table is a general guide and actual depth may vary based on personal preference and intended use of the pool. It is always important to prioritize safety, especially for young children or non-swimmers.

Factors to consider when choosing the depth

There are many factors to choosing the depth of a pool. The first factor is the climate. If you live in an area with a hot climate, you will want to choose a shallower depth so that the pool does not get too hot. The second factor is the size of the pool. A larger pool will require a deeper depth to accommodate more people. The third factor is the type of pool. An above ground pool can be round, rectangular, or oval in shape. Rectangular pools are typically deeper than oval pools because they have a higher capacity for water. The fourth factor is your budget. Above ground pools can range in price from a few hundred dollars to several thousand dollars depending on the size and features.

How to build above ground pool

Assuming you have already purchased your above-ground pool, the next step is to build it. Here is a detailed guide on how to do so:

  • Begin by leveling the area where the pool will be built. This can be done with a shovel or rented leveling equipment. The goal is to have a level surface for your pool so it doesn’t tip over.
  • Once the area is level, lay down a tarp to protect the bottom of the pool from sharp objects or debris.
  • Next, set up the pool’s frame according to the manufacturer’s instructions. Be sure to use all provided hardware and brackets for added stability.
  • Now it’s time to inflate the vinyl liner that will make up the walls and floor of your pool. Inflate it using an air compressor or pump until it is tight against the pool’s frame.
  • Fill the pool with water according to the manufacturer’s instructions, being careful not to overfill it as this could cause damage to the liner or frame.
  • Finally, add any desired accessories such as ladders, steps, diving boards, etc., and enjoy your new above-ground pool!


An above-ground pool is a great way to enjoy the summer with friends and family. Now that you know how deep they should be, as well as have a basic idea of the steps involved in installing pools. Hopefully, you feel more confident about taking on this project yourself. With careful planning and consideration for safety protocols, your above ground pool can provide years of fun and relaxation!
