In the world of Dungeons & Dragons, your digital tabletop is just as important as the dice you roll. For many Dungeon Masters and players using Virtual Tabletops (VTTs) like Roll20 or Foundry VTT, the resolution is a specific, "golden ratio" for high-definition battle maps.

Big resolutions can lead to big file sizes, which causes "map lag" for players with slower internet. 🖼️ Use WebP instead of PNG or JPEG.

Most modern monitors use a 1920x1080 (16:9) aspect ratio. However, VTT interfaces often take up vertical space with toolbars, chat boxes, and menus.
