The best thickness for a vinyl pool liner is typically 20 to 30 mils (0.020 to 0.030 inches). A 27 or 28 mil liner offers a good balance of durability and flexibility, making it a popular choice for most residential pools. Thicker liners (30 mil) are more resistant to punctures and tears, but may be less flexible and harder to install.
