You can do this two ways Go to the view menu and then to zoom and select zoom text only. Then to increase your font size use crtl and the plus sign (+) and to decrease your font use crtl and your minus sign (-)
Another way of changing font size is to go to tools and then content from here you can choose to increase your font size of the default font or click on the advanced box and change the fonts to how require them. Hope this helps.
