Actual font size documentation

[cgappsmatt]

I am trying to figure out if there is any documentation that goes over what exactly "Actual" means when you are changing the font size on a label. Logically I'd think it would mean what the actual size of the font is relative to what you set it to, but there's a second number that I am a tad confused about.

If I am using the font Arimo18 and I set the font size to 20. The actual size is listed as "10/18." What does that 18 mean? Is that the max size it can go? Or is it saying I requested a size of 20 but the most I can get is 10/18 of that?

18 is the actual size of the font that you should set it to if you want it to be crisp. You chose 20, which is bigger than what it's at, and since the label's content doesn't fit into the region, it gets downscaled down to size of 10.
