Andrew said: @SkyCaptain This is likely to end up in a Marketplace Module, and they like the map to be at 140px per grid. So halving the grid sizes means doubling the map size... and hence doubling the map dimensions/quadrupling the area and or file-size. The 140px grid guideline is so that when people zoom in, the map still looks good. That guideline is also based off of using a 1 unit sized grid which is 70px square. When you adjust the grid to half units (0.5), all you're doing is adding extra lines on the map. Nothing else changes. Token and maps do not resize when you change the grid size. It just provides better control on snapping to grid for drawings, tokens, and maps. You would not need to adjust the size of an map dimensions or file size.
