Lap pools are typically about 40 feet long, but they can reach up to 75 feet. Their width ranges from six to 10 ft. Experts recommend a minimum depth of 3-1/2 feet so swimmers don’t scrape their hands or feet on the bottom. If you do flip turns at the end of each lap like the Olympic swimmers, you need a pool that’s at least four feet deep.

Lap pools typically measure 40 feet long and fall anywhere from 6 to 10 feet wide. Pool builders recommend a depth of 3 ½ feet, and certainly not less than 4 feet if you do flips. This is, so swimmers do not scrape their hands and knees on the bottom while swimming.
