Same for all Linuxes, it's a current limitation of the Linux kernel. There's an open issue about it, essentially working out how to use the TPM to sign the memory dump so that secureboot will accept the signature and load it from disk.
You can get away with less if you don't hibernate while using a ton of memory. For example, I have 32gb RAM and 16gb swap. If I tried to hibernate while rendering a video, then something would go wrong (IDK what tho. Maybe it would just say 'no'?). But in most circumstances I'm just using like 8gb and hibernation works just fine.
Haven't used Mint in a while, but I think it's mostly a function of the kernel. IIRC, there's a nice GUI for selecting what kernel you want on Mint. Would probably only make a difference if you have new hardware and need a newer kernel.

On Debian, you need to have secure boot disabled in order to hibernate. I'm guessing it works similarly on mint

Which means hibernating is currently insecure on Linux as anyone can extract your disk and read the contents of your memory.
Google got around this with ChromeOS, something about user / kernel mode, but I forget how.

Gather a lot of mint, put it in your cave in a pile, and lay down on it before going to sleep for the winter.

You can't. Mint is a natural stimulant.

It’s sometime spicy for me

Someone can correct me if I'm wrong (I'm only half remembering), but don't you also need as much swap as you do RAM to hibernate?

I still follow the old twice-your-ram rule; 128GiB swap for meeeeeeee

Since you have no details, i'll just send you to a wiki.
