How to increase font size:

(taken from Microsoft Internet Explorer Help)
"When Web authors and designers create Web pages, they often specify particular type (font) faces, colors, sizes, and background colors. These settings are specified for each item, or in a "style sheet", which is a type of template for specifying how different styles should appear throughout a Web page or site.

You can override any or all of these settings, which is useful if you have limited or low vision. You can specify your font and color preferences for all pages that do not use style sheets, and then you can specify whether to use any or all of your preferences on pages that use style sheets."

1. Click on the View tab from the menu bar, point to Text size, then select your preferred setting.

2. If this does not change the text size, On the Tools menu in Internet Explorer, click Internet Options. On the General tab, click Accessibility (bottom right corner). Check the box that says “Ignore font sizes specified on web pages.” Then, change the font size from the View tab as in step 1. (note: this will take effect on any future pages you view. To change back to the normal size, uncheck the "Ignore" box again in the accessibilty tab.)
