I wonder if that is why they provide the "edit theme" functionality. Modified the font size and that seemed to do the trick.

Ah, good. I guess my edit was for nothing then. :)

Thanks. I'll look at this again later tonight. I believe it was the font size setting on the theme. 1.1em vs. small.

When things are smaller than you expect, a good assumption would be that some kind of percentage/proportional sizing is happening recursively, i.e. that you've got

.foo {width: 80%;}

somewhere and that has been applied twice or more, meaning that your width ends up at 80% of 80% of 80%.
