Above-Ground Pool Liner Size Calculator
Choosing the wrong liner size can lead to wrinkles, gaps, or premature wear. Enter your pool's shape and dimensions to get the recommended liner size and an estimated cost.
About this calculator
Determine the correct liner size for your above-ground pool based on shape, diameter or dimensions, and wall height, plus estimated liner material cost.
Frequently Asked Questions
Why do I need extra material beyond the exact measurements?
Liners need extra material for overlap, seams, and fitting around fittings like skimmers and returns, typically around 10% more than the exact calculated area.
Does wall height affect liner thickness needs?
Taller walls require more liner material for the sides but don't necessarily require a thicker liner; thickness (mil) is a separate durability consideration.
Can I use this for inground pools?
This calculator is designed for round and oval above-ground pools; inground pools have more complex shapes and typically need custom liner measurements.
