Alright so this is a little hard to describe, but basically I want to make custom maps for my future campaign. As an artist I'd like to draw them myself and import them in as opposed to assembling them piece by piece. Although getting the grid size to match up is a little tricky. You'd think a grid of squares would match up with another grid of squares, but no of course not. Anyway, my actual question was: What scale and grid sizes should I keep in mind in my drawing program while I'm drawing? And what's an easy way to make the grid squares in the image match up with the grid squares on the roll 20 map page?
