Dynamic Font Size in mobile devices?

So... I'm trying to add text into my mobile game, like score and the like, but I realized that the Font Size in GUIStyle doesn't work on mobile devices.

Checked around, seems like alot of people are saying that there is no other way other than to make multiple font files of the same font with different sizes.

Is there really no other way? Because my game is currently running on android as a test platform of sorts, and my other friends all have different phone sizes, so finding a way to do this without having so many different font files would help greatly...

Thanks!
