Pool Liner Thickness: What You Need to Know
When it comes to above ground pools, the thickness of the pool liner plays a significant role in its durability and longevity. In this article, we will address some key questions surrounding above ground pool liner thickness including why it’s important, how to measure it, and what thickness your liner should be. Let’s dive in.
Why does pool liner thickness matter?
The thickness of your pool liner directly affects how well it holds up to regular use, UV exposure, chemicals, and harsh weather conditions. A thicker pool liner offers enhanced resistance to punctures, tears, and fading, so your liner lasts longer.
That said, a thicker liner usually also means a higher price tag. By understanding pool liner thickness, you can choose an above ground pool liner that strikes the right balance between cost and durability.
How do you measure pool liner thickness?
When shopping for pool liners, you will generally see two common measurements in product descriptions: mil and gauge. Let’s look at these measurements so you can understand and better compare pool liner quality and prices when shopping.
Mil provides a precise indication of liner thickness — one-thousandth of an inch. For instance, a 20 mil liner is 0.020 inches thick, while a 30 mil liner is 0.030 inches thick.
Keep in mind that a mil is not equal to a millimeter, as many new pool owners think. One millimeter is actually about 39 mils.
Gauge is an alternative unit of measurement for pool liner thickness. Gauge varies based on industry.
Multiple industries and products use gauge as a form of measurement including gun barrels, wire, needles, and film. In some cases, a smaller gauge means larger or thicker. However, for the pool industry, a higher gauge means thicker material.
Comparing Gauge vs. Mil
Gauge and mil can’t necessarily be compared apples to apples. To help with conversions and understanding, a 25 gauge pool liner is approximately 20 mil.
How thick should an above ground pool liner be?
For most residential above ground pools, a pool liner thickness of 20 mil/25 gauge is recommended. It can stand up to moderate usage.
Please note that optimal pool liner thickness depends on usage, location, and personal preference. If you live in a harsher climate or use your pool more than an average homeowner might, discuss with a pool liner specialist to make sure the liner is durable enough to meet your specific needs.
