How to find the right Pool Liners AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Pool Liners
- Exact measurements
- For above-ground pools, measure the diameter or length and width, plus the wall height. For in-ground pools, provide a full measurement form with depths, the slope and the position of the break. A liner that is the wrong size wrinkles, stretches or will not seat.
- Bead type
- Match the attachment type: overlap, beaded, J-hook/uni-bead, or standard bead for in-ground track. The bead must fit the existing track or wall top, or the liner will not stay in place.
- Thickness
- Compare liners in mil (thousandths of an inch); be wary of liners listed only by gauge, which is not standardized. Sellers quote gauge numbers that sound thicker than the actual mil thickness.
- Wall height and depth
- Match the wall height (common above-ground heights are 48, 52 and 54 inches); expandable liners are needed for a dug-out deep center. A standard liner in an excavated deep-end pool will stretch and tear.
Brands that matter
- Smartline: Common maker of above-ground replacement liners in many sizes and bead types.
- Latham: Large in-ground pool and liner manufacturer.
What to avoid
- Liners listed by gauge with no mil figure
- Ordering an in-ground liner without a full measurement form
- Installing in cold weather, when vinyl is stiff and hard to fit
Questions
Gauge vs mil — which matters?
Mil is the real measure of thickness. Gauge has no consistent definition for pool liners, so compare liners by mil.
