You can change the size of the menus in Remote Buddy's preferences with a slider in the "General" pane.

If you want to make a menu even bigger or smaller than the slider allows you to, you can - while Remote Buddy is not running - change the scaling factor by entering this line in Terminal.app:

defaults write com.iospirit.RemoteBuddy menuSizePercentFactor -int SizeInPercentOfStandardSize

So, entering

defaults write com.iospirit.RemoteBuddy menuSizePercentFactor -int 300

would set the menu's size to three times that of the default.
