I'm realizing that people can get confused in figuring out the differences between Pixels Per Inch and Dots per inch. For example: a font with a size of 72 is 1 inch tall, because there are 72 vertical points to an inch in printing. So that means a font with a size of 36 is yes, sit down, only 1/2 inch tall. This link has a very simple calculator, and a nice explanation on it: http://tiporama.com/tools/pixels_inches.html
