Measurement Tips
Because oval pools are not circular, your measurements must be accurate:
-
Length: Measure from the inside wall at the longest point
-
Width: Measure across the center from inside wall to inside wall
-
Wall Height: From bottom track up to top rail
A mis-measurement can lead to wrinkles, improper fit, or installation issues — so double-check these before selecting your liner.
