# How do you measure square footage of a swimming pool?

Length x Width X Average Depth (Average depth is you take the deepest end say at 8 ft, Add it to the shallowest end say 3 feet. That gives you 11 feet cut in half 5.5 ft) So say length is 60 ft X width is 22 ft= 1320 ft x average depth at 5.5 ft =7260. Square footage 7250 sq ft The above answer is wrong. This is the answer to the question "What is the volume in cubic feet of a pool?" Which then can be used to determine the volume of water in the pool by taking this number and multiplying it by 7.48 to get the number of gallons in the pool. This assumes a rectangle pool. The correct formula is approx since pools most likely have many round corners and steps, but should work for determining the amount paint or tiles needed to finish a pool. (L x W) + (L x Avg Depth x 2) + (W x shallow depth) + (W x deep depth) = Total square footage of surface of all the pool sides and bottom. (60x22) = 1320 (60x5.5x2) = 660 (22x3) = 66 (22x8) = 176 1320 bottom + 660 (the two long sides) + 66 (small side) + 176 (deep side) = 2222 SF. Stated in different terms, you need the SF of the bottom, the SF of the two long sides, the SF of the shallow side, the SF of the deep side.
