Overlap vs Beaded Pool Liners: Which Liner Is Right for Your Pool?

If you're replacing your pool liner or buying a new above ground pool, you're going to run into one big question fast: Should you choose an overlap or beaded pool liner? They both keep water in and protect your pool walls, but the way they install, and how they look. It can make a big difference depending on your setup.

This guide breaks down everything you need to know about overlap and beaded liners so you can make the right choice for your above ground pool without second-guessing it later.

What Is an Overlap Pool Liner?

An overlap pool liner is exactly what it sounds like. The liner material overlaps the top of your pool wall and is held in place by plastic coping strips. You trim any excess after it’s secured. It’s a simple system that’s been around for a long time, especially for round and oval above ground pools.

Key Features:

• Fits over the top of the pool wall
• Secured with coping strips (plastic pieces that clip over the edge)
• Commonly used for round and oval pools
• Less expensive than beaded liners
• Requires some trimming during installation

What Is a Beaded Pool Liner?

A beaded pool liner has a thick bead along the top edge that snaps into a track (called a liner receiver) installed along the inside of your pool wall. It creates a clean, uniform finish without overlapping or trimming.

Key Features:

• Snaps into a track along the top of the wall
• Gives a smooth, professional look
• Faster and easier to install (once the track is in place)
• Comes in multiple bead types (standard, J-hook, unibead)
• No trimming required

What About Unibead Liners?

Unibead liners are a hybrid option. They work with either a beaded track or can be hung like a J-hook liner. They're more flexible and give you options if you're not sure what setup you'll want later on. If you think you might switch liner types down the line, unibead is a good way to keep things simple.

When to Choose an Overlap Pool Liner

Go with an overlap liner if:

• You have a standard round or oval above ground pool
• You want to save money
• You’re comfortable doing a bit more manual work during installation
• You don’t care as much about having a perfectly clean liner edge

When to Choose a Beaded Pool Liner

Choose a beaded liner if:

• You want a cleaner, more finished look
• You already have or plan to install a liner track
• You want to make future liner replacements easier
• Your pool came with a beaded setup

How to Tell What Type of Liner Your Pool Has

If you're replacing an existing liner and not sure what you have, check under the top rail of your pool. If you see a plastic track running along the inside of the wall, it's likely set up for a beaded liner. If there's no track and your liner folds over the wall, it's an overlap liner.

Which Liner Lasts Longer?

Liner lifespan depends more on thickness, UV protection, and water chemistry than whether it's overlap or beaded. A high-quality 25 mil liner will last longer than a thin 20 mil liner, regardless of style. Keep your water balanced and cover your pool when not in use to get the most life out of any liner.

When it comes to overlap vs beaded pool liners, there’s no one-size-fits-all answer. If you're going for a budget-friendly option and don’t mind a little trimming, overlap liners are a solid choice. If you want a cleaner finish and easier liner swaps in the future, beaded liners make life easier.
