Changing the Default Text Size
Use the menus to change the default size so that every browser session reflects the new size. Two toolbars provide text size settings: the command bar and the menu bar. The command bar is visible by default, while the menu bar is hidden by default.
Using the Command Toolbar
The easiest way to change text size is using the Internet Explorer command toolbar:
Using the Menu Toolbar
Alternatively, use the Internet Explorer menu toolbar:
Using Accessibility Options to Control Text Size
Some web pages have explicitly fixed the size of text, so the methods above don’t work to change it. Internet Explorer provides a range of accessibility options that can override a web page’s settings. If you try the methods here and your text is unchanged, use Internet Explorer’s accessibility options.
Temporarily Change Text Size Using Keyboard Shortcuts
Most browsers, including Internet Explorer, support common keyboard shortcuts to increase or decrease the size of the text. These affect the current browser session only, in fact, if you open another tab in the browser, the text in that tab reverts to the default size.
To increase text size: Press Ctrl + (the plus sign) on Windows, or Cmd + on a Mac.To decrease text size: Press Ctrl - (the minus sign) on Windows, or Cmd - on a Mac.
Note that these keyboard shortcuts actually zoom in or out, rather than increasing only the text size. This means that they increase the size not only of text but also images and other page elements.
Zoom In or Out
A zoom option is available in the same menus that have a text size option, i.e. the Page menu on the command toolbar and the View menu on the menu toolbar. This option is the same as using the keyboard shortcuts Ctrl + and Ctrl - (or Cmd + and Cmd - on a Mac).
