How to Determine the Size Underlayment You Should Buy:

1.) Determine the total sq ft of your pond liner: Example 20'x30' = 600 sq ft

2.) Divide the total sq ft of your liner by 15 (this is the width of the rolls they come on): Example 600 sq ft / 15 = 40 

Example: You would need to purchase a 15'x40' underlayment

The underlayment is impressive

So I bought the pond liner because they recommended it- didn't know if it would be worth it or not but wasn't a terrible amount of money. Boy it was an impressive product. It felt almost as thick as craft store felt, but made from some type of polypropylene or similar. I first tried to cut it with a brand new utility knife and couldn't get the blade in (yay, though it led to a brief panic), oddly cut perfectly fine with scissors.

Worked Perfectly

The underlayment I had ordered was exactly what I needed. This underlayment was so tough I had a hard time cutting it with a new razor blade. I know it will protect my liner.
