For your pool measurements we only need the longest length (not including any step that sticks out from the perimeter of the pool) and the widest width for most shapes (basic and non-standard).

For True-L pools, we need the longest length and widest width (main part of the pool) and then the width and length of just the extension. Mark extension sizes in the length and width fields with the text: "ext:" - for example-
Pool Width: 12'5" ext: 12'5" / Pool Length: 25'3" ext: 10'5"

With a Lazy-L we need the widths at both ends of the pool (sometimes they are different) and the lengths of all 4 straight walls. You will need to complete our measurements form for these measurements (linked below).

For round pools we only need the diameter of the pool filled out in the "Pool Width" field.

Please note: You can download and fill out our measurements form (linked below) to provide detailed measurements of your pool.
