Finding the right replacement 24-foot round above ground pool liner can feel like an overwhelming task. The tons of options, specifications, and calculations can be overwhelming to pool owners unfamiliar with replacing theirpool liner. But, finding the right liner doesn’t have to be so hard; in fact, it can be broken down to four key factors: Liner Type, Wall Height, Liner Thickness, and Aesthetics.
And before we start, if you’re interested in installing the liner yourself, take a look at our guide: How To Install Above Ground Pool Liners
What liner type do I have: overlap, beaded, or unibead?
There are four common liner types used in standard above ground pools: Overlap, beaded, J-Hook, and Unibead.
- Overlap: Drapes over pool wall, secured with coping – The most common above ground pool liner installation. Perfect for pools with wall heights from 48″ – 52″
- Beaded: Snaps into a track – Beaded/Hung liners simplify liner replacement – No disassembly of pool required. Also great for assuring proper liner alignment. Perfect for pools with wall heights from 48″ – 52″
- Unibead / J-Hook: Works as either overlap or beaded – Beaded/Hung liners simplify liner replacement – No disassembly of pool required. Also great for assuring proper liner alignment. Perfect for pools with wall heights from 48″ – 52″

What thickness liner should I choose (20 mil vs 25 mil)?
Liner thickness is one of the more confusing aspects of picking a pool liner. You’ll commonly see liners measured by their ‘Gauge’ or their ‘MIL’. These terms are often used interchangeably, but are not like-for-like units of measurement.
- MIL = a True Thickness Measurement (1/1000 inch)
- Gauge = Based loosely on MIL, but the specific ‘gauge’ size varies by manufacturer
Pureline brand pool liners are listed with either a Standard Gauge or Heavy gauge; the respective MIL measurements are .32 mm and .50 mm.
What accessories are often purchased with replacement above ground pool liners?
When buying a replacement above ground pool liner, most pool owners also purchase a set of accessories that either protect the new liner, simplify installation, or extend its lifespan. These add-ons are often recommended because a liner install is the best time to upgrade or replace them.
- Liner Pad / Floor Padding – Creates a smooth, cushioned base and protects against rocks, roots, and debris
- Wall Foam Kits – Adds a soft barrier between the liner and pool wall, reducing punctures and improving feel
- Peel and Stick Wall Cove – Provides a uniform shape to the pool bottom edge and prevents the liner from getting pinched between the pool wall and floor.
