Change font size

Unity Engine
1

I have text to display my character current health but I want the text to be bigger how would I make it change the font size, by the way here is my code:

var hp = 100;
function OnGUI  () {
GUI.Label (Rect (300,300,100,100),hp.ToString());
}

Have a look at the Unity docs for custom GUI’s. If all you want is to change the size of a single GUI element then look at GUIStyle.
