CSS font sizes in em and relative
How about setting font-sizes in em and relative sizes?
1em for main text and in percents for others.
(I mean as default config of redmine)

I found out the most notable hindering comes from the fact that textareas and input fields don't scale because they don't inherit from body. See the attached patch for a possible solution.
Otherwise it's a pretty simple search and replace for font-size elements.
