Your browser determines the default appearance of fonts (including size, style, and color) in Yahoo! Mail. To configure Yahoo! Mail so that the emails you receive appear either larger or smaller, do the following:

Note: Only the incoming and outgoing message text is affected by following these steps.



Log in to your Yahoo! Mail account.

Click the %26quot;Mail Options%26quot; link located near the top right-hand side of the page (If you are using IE, you may also access the options area of your account by clicking on the %26quot;Options%26quot; link located in the navigation box, which can be found by clicking on the arrow next to the mail tab on the top left-hand side of the page.)

Click the %26quot;General Preferences%26quot; link.

Locate the Font Size heading.

Selecting %26quot;smaller%26quot; will make the font size of messages one size smaller than your browser's default setting, while %26quot;larger%26quot; will make the font size one size larger.

Once you have chosen a new font size, click the %26quot;Save%26quot; button to put your new settings into effect.

Yahoo! Mail will confirm the changes by displaying %26quot;Your changes have been recorded.%26quot;
