Choosing between 15’x30′ liners can seem a bit daunting at first. With multiple liner styles, wall height specifications, and vinyl thickness options available, it’s easy to feel unsure about which one will fit your pool properly especially if this is your first liner replacement. Fortunately, the process is simpler than it appears. Most pool owners only need to focus on four main factors: liner type, wall height, liner thickness, and the pattern or design.

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 Liner thickness is one of the trickier things to compare when shopping for a pool liner, mostly because the industry uses two different units: Gauge and MIL, that sound interchangeable but aren’t.
MIL is a straightforward measurement: one MIL equals one-thousandth of an inch. Gauge, on the other hand, is a looser term whose actual thickness varies from one manufacturer to the next, which makes side-by-side comparisons between brands unreliable.
Pureline liners come in two thickness options. Their Standard Gauge liner measures 0.32 mm thick, while their Heavy Gauge liner steps up to 0.50 mm; a meaningful difference in durability, puncture resistance, and how well the liner holds up over time.
What liner type do I have: overlap, beaded, or unibead?
Above ground pool liners come in four common types: Overlap, Beaded, J-Hook, and Unibead. Each installs differently, so it’s important to match the liner type to your pool’s wall design before buying.
- Overlap: Drapes over the top of the pool wall and is held in place with coping strips. This is the most traditional and widely used installation method. Best suited for pools with wall heights between 48″ and 52″.
- Beaded: Snaps into a dedicated bead receiver track along the top of the pool wall. Because the liner locks into the track, replacement is straightforward; no pool disassembly required. The track also helps keep the liner evenly aligned during and after installation. Best suited for pools with wall heights between 48″ and 52″.
- J-Hook: Hooks directly over the top of the pool wall without needing a bead receiver track. Like the Beaded liner, no disassembly is required for replacement, and the hooked design helps maintain proper alignment. Best suited for pools with wall heights between 48″ and 52″.
- Unibead: The most versatile option; a Unibead liner ships with a removable bead strip that lets it function as either a Beaded or J-Hook liner depending on your pool’s setup. One liner, two installation options. Best suited for pools with wall heights between 48″ and 52″.
