If you want to make your profile/layout tiny then just check the checkbox on the left. You can leave everything else just default or you can change it if you know what your doing.
To make your profile look tiny, you might want to make sure all your text sizes are small, maybe make them 8px-10px. Also dont forget to keep checking the Live Preview and when your satisfied with the layout then just check the checkbox that says "Show/Hide Code". That will show you the layout code that you need to copy to your profile in About Me or Who I'de Like to Meet Section. :)
