Hi! This is my first post, and I tried to find the most relevant thread to post this on, and this general one seemed the best.

Anyway, I like to make maps primarily for D&D, and I was wondering, what's a good way to try and keep believable distances in your maps? For instance, I can say that Town X is 3 days travel from Town Y, but what's the easiest way to keep that distance consistent within the scale of the map? I've always had scaling issues. Thanks!
