To my knowledge, imperial cabinets as well as mammoth plates don't have precise dimensions. Imperials are at least twice the size of a standard cabinet, but could be larger than that. Mammoth plates are as the name suggests very large mounted photos, but there are so many different sizes that there is no standard. I would say Leon's Beaneaters photo was closer to mammoth plate, or at least a very large imperial. It kind of straddled the line.
