Re: sims 3 UI too small

@lunarzebra  The UI doesn't scale properly and is dependent on the resulution you're using.  Having said that, if it's not changing size when you change resolutions, try quitting and restarting the game.  If that doesn't help, go into Documents\Electronic Arts\The Sims 3 and move options.ini to the desktop.  When you launch the game, all your options will have reset to the defaults.  Don't change anything yet; just start a new save and see if you can make the UI the size you want.
