I've purchased a couple of map, tile and token packs from the Roll20 and I'm a little confused on how I'm supposed to now the appropriate size for an image given the standard 1 unit grid on Roll20, mostly because I'm not sure it's consistent between different artists. For example, I've purchased the Nature Pack from Brass Badger. The images all include sizes in the name, but I'm not sure which measurement they are exactly referencing. For example, there are forest floor tiles that come size they are 150x150. Is that supposed to be 150 feet in-game feet, given the standard 1 unit = 5 feet? That's what seems logical to me, but when you drag them in from the art library, they come in much smaller at 10 feet by 10 feet.
