Map sizes of the official scenarios?

Is there a way to quickly see what map sizes are used in the official scenarios (e.g. American Civil War, Viking Destiny, Paradise Found), for example by looking at certain text files or looking at certain reference page? This information would be useful for me to decide which scenario to play next, and I'm also planning to update this wiki to help other people make similar decision

As I recall, most of the scenarios are on a huge size map (or bigger than huge)

Depends on which scenarios

You can check out the sizes via World Build just look into the DLC folders for scenarios

Those that don't use a map script will be by default the same size. so go check that
