What Size Pond Liner?

I’m building a koi pond and I don’t know what size pond liner to get. It’s 9’ by 4’ and it’s gonna be 1ft deep in the shallow areas and 2ft deep in the deeper areas. Any suggestions for what size pond liner?

 

I would aI'm in excess of 14' x 8' and then trim it down. Its easier to remove liner than add some

Would a 13 x 10 ft pond liner work?

Should be enough IMO, but may be a little tight for the 9ft part

 

I have another question. How big is my pond? Dimensions are 9’ by 4’ and is 1 ft deep in the shallow area and 2’ deep in the deep end

I meant how many gallons not how big

Depends on the side of the shallow area. A basic design idea sketched out on paper will help give a close to perfect estimate.
