Is this the year for replacing your vinyl pool liner?  Are you wondering whether you should spend the extra money to purchase a thicker liner?  The thickness of pool liners is measured in mil or gauge units.  A mil is exactly equal to .001 inch and can be measured using a micrometer.  A 20 mil liner, then, will measure .020 of an inch thick.  A gauge is not an exact measurement, and the same number may vary in thickness depending on manufacturer, but it is roughly the same size as a mil.

Spending the extra money for a thicker pool liner depends on how your pool is used.  If your pool is enjoyed heavily over the course of a season and tends to take much abuse by the swimmers who use it, choosing a pool liner that measures 28 mil thick, or close to it, may be worth the extra cost.  Thicker pool liners offer better UV protection, too.

No matter how thick your vinyl pool liner, make sure the one you choose fits your pool properly.  Also, be sure to maintain proper chemical balance in your pool’s water.  Proper fit and chemical balance are two of the most important factors that can affect how long your vinyl pool liner will last.
