I have spoken with several pool companies which claim that a free form pool's dimensions are calculated as the longest length by the widest width. This seems like a very inaccurate way to calculate the total square footage of a pool. Does anyone have any knowledge of what the industry standard is for calculating the total square footage of a pool? Is it really that simplistic which means that a PB can claim a 700 sf pool and actually only deliver something like a 575 sf pool if one gets creative.
