If you want more fine-grained control, click "Customize Font". On the Customize fonts screen, you can select a font by point size (from 9 all the way to 72, with 16 pt being the default) using a slider. As you move the slider, the point size will display just above it. You can also set a minimum font size, which ensures that websites never display fonts that are too small for you to read.
