An above-ground swimming pool is an investment you’ll enjoy for years to come, but there are many shapes and sizes to choose from, so it’s important to do your research before making your selection. This guide will explore how above-ground pool sizes vary and why your choice is so essential.
What are the different above-ground pool sizes?
Professional companies like Intex, Wilbar, and Lake Effect manufacture above-ground pools in a wide variety of sizes. Here’s a look at the most popular dimensions:
Round above-ground pool sizes
Structurally efficient and cost-effective, round above-ground pools are generally available in the following diameters:
-
12 feet
-

-
18 feet
-
21 feet
-
24 feet
-
27 feet

-
12 feet x 24 feet
-
15 feet x 24 feet
-
15 feet x 30 feet
-

Rectangular pool sizes

-
9 feet x 18 feet
-
12 feet x 24 feet
-
16 feet x 32 feet
-
18 feet x 36 feet
Pool depth options
Whether large or small, the actual water depth in any pool is typically 4 inches to 6 inches below the wall height, to allow for the skimmer opening. On average, most above-ground pools feature walls spanning from 48 inches to 54 inches, though some specialty options may be deeper or shallower. Keep in mind that these models typically only have one depth.
Types of above-ground pools
From inflatable and soft-sided pools to steel-framed spas, there are many
What parts does an above-ground pool consist of?
No matter what size or shape you select for your above-ground pool, you can expect it to include the same basic components as other models:
-
Base: Prepared foundation that provides stability.
-
Pool wall: Supported by a base track, vertical uprights, and a protective top rail.
-
Waterproof liner: A membrane that holds in the water.
-
Pump: Circulates water through the filtration system.
-
Filter: Removes dirt and debris from water.
-
Return jet: Sends clean water from the filter back into the pool.
-
Ladder or steps: Provides a safe entry and exit point.
Above-ground pool materials
Plastic inflatable pools usually don’t last beyond a few swimming seasons, but a well-made above-ground pool can provide summer fun for 20 years or more. Resin and metal frame pools are durable and cost-effective. Aluminum won’t rust like steel, making it a better choice for the humid Florida climate.
Above-ground pool liners
Above-ground pools of all shapes and sizes generally include a flexible vinyl liner. Depending on the thickness, climate, and routine maintenance, it may last five to 12 years.
Fiberglass is a popular alternative to vinyl liners, but it’s sold as a solid shell, much like an in-ground pool. In fact, many people who purchase fiberglass molds build a deck around the structure, so it functions more like a pool that’s flush with the ground.
What to consider before installation
Even if your above-ground pool doesn’t require a construction permit, extensive ground preparation, or a permanent foundation, it’s still a big investment. Don’t just settle for the clearance unit with the lowest sale price. Instead, take time to consider your goals, assess your landscape, and design the ultimate backyard oasis. Here are a few more factors to keep in mind:
Size and shape of the site
The size of your above-ground pool will be determined in part by your yard’s dimensions. Measure the available space, then subtract 3 feet to 6 feet around the perimeter for adequate clearance. Don’t forget how you’ll use the space when you’re not swimming. You and your family may also want space to grill out, plant a garden, or kick a ball around.
Of course, pool shape also plays an important role in overall functionality. Here’s a quick guide to consider as you browse for the perfect pool:
-
Round pools: Ideal for square yards and open spaces.
-
Oval pools: Great for narrow or rectangular lots.
-
Rectangular pools: Maximize swim length and suit modern landscaping designs.
Sunlight, trees, and obstructions
Before buying an above-ground pool, ensure you understand every single feature of your space. Nearby trees can shed leaves, pollen, and seeds that drastically increase your maintenance checklist. Meanwhile, buried gas lines, septic tanks, and tree roots can present major problems during and after installation.
Budget and materials
The materials you choose for your above-ground pool directly impact your upfront costs, long-term maintenance expenses, and your pool’s overall lifespan.
