It's fine if they don't exist or if you want to keep the size variable or it simply doesn't matter. My request is more for those situations where artists creating these do have a recommended grid size. For instance I just purchased a pack on Roll20 from a well-known battlemap vendor but there's no suggested size (unless I want to go count the squares on the gridded versions -- which I've certainly done). But on the same artist's patreon page, the dimensions are listed there. It would helpful and appreciated to have them in both places. Cheers
