So i recently exported a map thats 70dpi which is what Roll20 wants for the grid, (Or so it says in the map settings, in the guides it says 72) my map was 100x80 hexes big and i set the roll20 map to 100x80, I figured it would fit, right. It doesnt, why? Because after exporting the map in all kinds of resolutions, (The resolutions that Roll20 map setting said with the dpi it said) I just couldnt get it to align. And after a long time i wanted to try the aligning your map tutorial, so I wanted to check where the middle of the map where so could locate it.. and i found out Roll20 hadnt made my map 100x80, it had only made it 90x70, so its no wonder I for the life of me couldnt get it to align. Apparently Roll20 doesnt add the amount of Hexes the map setting says. When I upped the setting to 110x90, my 100x80 70 DPI map fit like a glove.. I have no idea if this is intended or just a mistake, but it would have been nice to know before spending two hours trying to align the map XD
