Getting ready to order a new pool liner and not sure what size I should order for the wall. Last time I ordered a 54 and had a lot of excess so I thought it was a 48 but apparently that’s very rare to have a 33 x 48 so now I’m thinking my floor may have been too high. Also it was a GLI liner so it may not have been true to size. From the pictures what size do you think it is?
