The font size of menus inside the LiveEditor pages can be edited by going to Layout Settings > Header & Navigation > and then select the relevant menu that you are using from:

If you want to change the font size of menus inside your OptimizePress blog (if you're using the OptimizePress Theme) go to Blog Settings > Layout Structure > Header & Navigation Preferences > and select

- Blog Primary Navigation
or
- Blog Top Navigation

You can then use the options there to customize the font size and colours of the menus inside your blog

If you are using a different blog theme, you would need to check with the theme provider for their options on how to change font sizes for your menus
