Measure before ordering
Start with the measuring form that most closely matches your pool shape. Good measurements are what let us build the liner to your actual walls, floor, hopper, and shape details.
Video help
The written forms below are the source of truth, but these videos are useful before you start taking dimensions.
Common pool shapes
These are the most common starting points for custom inground liner measurements.
L-shape, dogleg, and boomerang pools
If your pool turns or angles, pick the form with the closest layout. The form will guide which dimensions to collect.
Specialty shapes
Hexagon and octagon forms open as PDFs. We can help review measurements if the layout is unusual.
Before you order
Since more homeowners are installing their own swimming pool liners, we keep the measuring process straightforward. The form helps you capture the dimensions needed to make a custom liner instead of guessing from a stock pattern.
Read the measuring tips and installation guide before you start. Good measurements can save time during installation and help the finished liner sit cleaner in the pool.
After you identify the shape and collect measurements, continue into the quote flow to choose pattern, thickness, and options.
