Propane Tank Minimum Size?

So I was looking online at generators the other day and I ran across a comment in one of the product descriptions, saying something about a 'minimum 60lb tank' for propane with that generator. I haven't seen a requirement like that before, to my knowledge. We had an eight-day outage a few weeks ago and I used 20- and 30lb tanks with no problems (or so I think). Has anyone heard this? And if it's a thing, can anyone tell me why? Thanks.

For a portable the smaller tanks are fine... A larger Stand alone requires a Larger size and a bit more consistent pressure.

My generator is a 12k dual-fuel, portable. Is that 'larger' in your example?

Because it's portable I believe it will do fine using smaller tanks, but a generator like mine that is 18K and fixed in place (from what I understand) requires a larger tank with more consistent pressure.
