These are stock catalog sizes as of our last update. If your exact dimensions fall between listed sizes, order the next size up — you can trim excess liner, but you can't add material once it's installed. For ponds over roughly 25' in any dimension, or irregular/multi-level shapes, call us at 888-825-6214 and we'll help you get the cut right.
