How do I fix full height when embedding game?

Whenever I embed my games, it always requires the height to be higher than the game because it shows a black bar above the game.

How can I fix this?

You can use Scale Outer for fullscreen scaling. It will show more of your layout instead of black bars, so make sure there is something nice there like a background or a simple solid color. Also, make sure your GUI elements are properly anchored. Check out the official tutorial by Ashley on scaling modes, it has all the information you need.

Ok thanks!
