What are the specifics for avatar pictures (width/height)?

Hello,

I am planning on using a personalized avatar picture and thought of possibly drawing it myself using Photoshop. Thus I would very much like to know what are the maximum specifications possible (width/height, preferably in cm?)

Greetings,

Thank you. As you can see at my avatar it has worked.
