Buying an above ground pool is an exciting decision, but choosing the right size can feel overwhelming. You’ll want a pool that fits your outdoor space, meets your needs, and fits your budget. This guide will walk you through everything you need to consider when deciding on the size of your above ground pool.
The first step in choosing the right pool size is knowing how much space you have to work with. Use a tape measure to determine the exact dimensions of your backyard or the area where the pool will be installed.
Things to Consider:
The size of your pool should also depend on who will use it and how they plan to enjoy it.
Different activities require different pool sizes:
Pool size has a big impact on cost—not just the upfront price but also ongoing expenses. Larger above ground pools require more water, chemicals, and energy for maintenance.
Budget Tips:
Before buying your pool, make sure to research local zoning laws and HOA regulations. Some communities have restrictions on pool size, placement, or fencing requirements.
Above ground pools come in different shapes and sizes, and some require more space for installation and storage than others.

When choosing the size of your above ground pool, balance your available space, intended use, and budget. A pool that’s too small can feel cramped, while one that’s too large may overwhelm your yard and wallet. Take your time to measure, research, and plan, and you’ll find a pool size that’s just right for you.
You’ll need enough space for the pool itself plus 2-3 feet around it for maintenance and safety. Make sure to measure carefully and account for any obstacles in your yard.
The most popular sizes are 18-foot and 24-foot round pools, as they provide a good balance of space and affordability for most families.
