I have a dumb question.

The MM that is listed on LF lenses, how is it derived? Like, there's 4x5, 8x10, 20x24 ... Etc in between those etc, so how do you determine for one if the lens will Cover the surface area. And two what the view would be like when you imagine which lens focal legnth to use? Can you use this lens on all LF sizes or only some, and how do you figure that out?

There's a link with info comparing many large format lenses.

It gives the coverage circles for all potential formats for each lens also.

The MM is merely the focal length. 'Coverage' on the film plane is a separate spec.
Inspecting the charts at the above site will help 'get your head around it'.
