Pro Tip: How to Calculate Average Depth

Most pool owners get stuck on "Average Depth." Here is the simple formula:

(Shallow End Depth + Deep End Depth) ÷ 2 = Average Depth

Example: If your shallow end is 3 ft and your deep end is 8 ft, then (3 + 8) ÷ 2 = 5.5 ft.

*Please enter all dimensions in FEET for accurate results.
