Personal dashboard

Hi I was wondering if someone could be nice enough and tell me the minim dimensions to use for the banner space near your avatar, it would be very much appreciated.
I know its a frivolous thing but, I would just like to know.
Thanks. ☺️

Please. ☺️

960 x 160. Hover your mouse in the middle of the banner space and a box will appear telling you what all to do.

Awesome thanks! ☺️
