Changing font size in sidebar of finder windows?

I have one user account with small (say 9pt) Sidebar items in the custom list of Folders/Places. That user was migrated from Leopard but I do not recall if it came over like that or I set it up. In another user on same MBP the Sidebar items are significantly larger (say 13pt) and I would like to change them to be about 9pt like my other user account.

There are many threads on communitties which say this cannot be done but obviously it's possbily just out of the respondants knowledge set, so please do not answer it cannot be done :-)
