If you're struggling to align your image's grid with Roll20's, our align to grid tool can assist you.
Sometimes you might want to use a pre-made battlemap that already has a gridded surface. Set the size, and never worry about resizing when you drop an image again. In addition to smart sizing, you can now set your own grid dimensions for uploaded images. Smart sizing works on personal uploads, not Marketplace purchases.The feature works better with gridless map images.
Smart Sizing does not work if the map is smaller than the current size of the map.This feature only works when a map is being placed on a blank map layer.Press the button “Don’t show me again” and continue with your dungeon-making! You can always choose to fit the map to the page yourself, or use our align to grid feature. If you add an image to an empty map layer, you will be prompted to resize the page to fit the map.
The Smart Sizing feature allows you to change the page size to match your map when you place it on the map layer.
