Yep, my bad. Sorry to both of you!
Liner thickness?

I KNOW I'M ALL HEART
If you’re going to confuse me with anyone, @Mmathis is a gerfext choice!
so I have the frame built and the hole dug. The reason I didnt know the exact dimensions is because the depth of the hole ranges a bit because I am going to be angling it so koi poop gathers in one crevice where it can be cleaned. (the angling will be done once the frame is in place)
All that needs to be done is set the frame in the hole and then attach the liner (along with my netting, shade, and weed barrier I bought)
I worded it as if I was just beginning my build because the actual building part for me is going to be adding the koi, designing my filtration process, and adding a waterfall to it. This is just the very beginning for me even though the actual construction for the frame is already complete.
After doing some research I did decide to go with the 15x20 45-millimeter EDPM vevor liner as it seems to be the cheapest option for this type of liner. I know having a few extra feet is good but what I am going to do is angle the bottom of the pond so fish poop builds up at the bottom, where I can clean it. This will also reduce the size of the liner needed so it should give me the extra few feet I need.
heres a picture of one of the side frames and the hole by the way! (the side frame is going to be a lot more reinforced than you see here because this is just one of the sides, and the longer 12 foot side includes 4x4s for extra support, and the inside is going to be 1 1/8 plywood, along with 4x4 posts on the ends) This construction may not last as long as a concrete pond and I am aware of that, however I have seen a lot of this exact design online and it seems to be able to support this size of pond, especially because I dont plan on filling it up all the way. So the water will only be going above ground about a foot and a half or so.

I’m definitely NOT a pro but I wouldn’t go any less than 45 mil.
.45 mil is standard for epdm there is also 60 much heavier more puncture resistant but more in it seals around what ever pokes through. Like any rubber it's flexible and epdm is very much so though 60 is harder to work with but still easier than hdre unless your just doing a gradual sloped farm pond.
I’m well sick bought epdm 45 mill liner it’s leaked from beginning all striped out trying to find leak is concrete a better option my pond is 18 x26 8 feet deep with french drain with 35 feet head waterfall but it’s the leak doin my head in advise please

How do you know it’s leaking?

Please learn from my mistake. We have had a pond now for 15 years. A year ago a tree fell in our pond and put a hole in our liner. We quickly replaced it using what was available at a nearby store - I forgot about thickness being important and just used something that was a “pond liner.” It started a slow leak within 2 months. I decided it had been defective and bought another one. It has now started to leak again and we will have to redo the whole thing again. This time I reread my “Ponder’s Bible,” and realized our mistake. Unfortunately we have now stressed our fish and will need to stress them yet again! Buy the thicker liner (like we did the first time and it lasted many years!)
While we love lessons learned. Your post is going to be confusing for those who do not know better.
Thickness. while it does of corse have its merits. The type of material that is used is even more important in my eyes.
For instance I believe pvc liner which is commonly used for both above ground and liner swimming pools for half a century or more is thicker than Epdm.
But I would never choose pvc over Epdm. Epdm does come standard in two thicknesses one being .045 and the other .060 . Now I have used both over the years and while .060 is tougher it is also heavier and does not bend as nicely as does it's counterpart .045. The most popular for garden ponds is the .045 or better known as 45 mil Epdm. I have this in my pond with up to 5000 pound boulders sitting on the liner. The key being that the rock sits on a piece of geotextile fabric. So no sharp edges of the rock can cut the liner.
When the liner is sandwiched properly with fabric, sand or even a thick layer of gravel. Your liner will last for decades if not half a century .
EPDM has a average of a 40 year warrenty when left out in the sun on a roof and the sun is Epdms enemy.
Hdpe or ldpe are two other materials that are used but more for a big farm pond. Instead of using clay or benetonite.
