I am wanting to create a nice design in Photoshop and print it on a mug. The printing will be done by a printing company, but I am gonna need to provide the design.

The question is: What are the standard dimensions in pixels for a mug design? If I'm totally misinterpreting the requirements, then what would be the best way to create a mug design in Photoshop?
