Measure the length and width of your pool at water level. If you have any step areas, then measure the step area separately as illustrated, so we can manufacture the pool blanket in one piece.

If the pool is not square, then you may have to form a rectangle around the pool with a length of string (rope, cord or even your garden hose) to give you your maximum water level length and width. We supply oversize to allow for an upturn and shrinkage, so the exact water level measurement is all that is required.
