Fits very well and is a decent thickness. There is a little extra on the diameter to cut to fit if you want. We didn't bother.I have used these for our smaller pools with great results. Several seasons with no bubble shedding. The plastic eventually softens and tears after several seasons, but I didn't have a problem with it breaking down before that like the Chinese made ones.This one is made in Canada.
