.Answer the 2 questions below and click 'Calculate Liner Size' to find out!  After you know the size of pond liner you need, you can visit our Choosing a Liner page to choose a specific liner!

1) Choose Pond Style:

pond with vertical walls
OR
pond with gradual slope bottom
OR
pond with sloping walls and flat bottom

2) Pond Surface Dimensions (feet):

Len x Width x Depth


For the dimensions above, choose the widest and longest parts of your pond. If you have multiple depths in your pond, use the deepest area. If you have many different levels, you might end up with a little extra liner. However, a little extra liner is much better than too much liner!
