How to increase or decrease the font size
in Internet Explorer, posted Oct 28th 2011
If you can’t read some tiny text on a website, or you mistakenly changed the browser font size, adjusting the font size is very helpful.
The easiest way to increase the font size is to hold "Ctrl" then press the "+" or "-" key. Logically, the "+" key increases the font size, while the "-" key decreases it.
An alternative way to adjust the font size is to hold "Ctrl" and scroll the mouse wheel up or down to adjust the font size.
There's also a menu option to set the zoom level; go to the "Tools" menu (the one with the gear icon on it), and then check the options under the "Zoom" submenu.
