First I want to explain how to make your map fit with the roll20 grid. I'm new here so it took me a while to figure this out. Secondly I need a little help with some map issues. Let's say you have a 34x22 square grid map. Click on the page toolbar and create a new page. On the page toolbar click on the page settings for your new page. In the boxes for page size type in 34 and 22. Optional: choose a color for the grid. Dark lines show up better on light maps and vice versa. Click OK . Select the new map from the page toolbar. Make sure you are on the Map and Background overlay. Add the image for your map. Right click on the map. Under Advanced select Set Dimensions . From the drop down menu select Units . In the boxes type in 34 and 22. Click Set . Click and drag the map so the corners line up with the edge of the page. Here is where I need a little help. Sometimes the maps that I use have a border around them. It messes up the spacing and I can't get the grids to match up. Short of hacking up the map in photo shop, is there a way to get the grids to line up. Also I haven't tried this with a Hex grid so I'm not sure how well it will work.
