Mail Gmail Tweet Share Email The tiny fonts that are so commonly used by email providers make it possible to pack a lot of information it very little space. Unfortunately, this downsized information is often difficult to decipher and digest. Fortunately, if you're a Yahoo! Mail or Yahoo! Mail Classic user, you can make the display bigger by default which allows for easier reading and much less eye strain. Make Yahoo! Mail Display Messages in a Larger Font To read your emails in a larger font, you'll have to make some changes outside of Yahoo! Mail. Most web browsers have the ability to increase or magnify the size of the site displayed in the browser. You may see this option as a magnifying glass with a plus in the center of it in the address bar. If you do not, you may need to go to the settings menu to find the Zoom controls. This allows you to make everything in the browser display larger. Of course, it will also make everything on pages you visit other than Yahoo! Mail larger as well. Alternatively, you may be able to use the keyboard and/or mouse shortcuts to zoom in and out on in your browser display. To use the keyboard, click inside your browser window and then press and hold the Ctrl key while pressing the + (plus) or - (minus) key to zoom in and out. If you have a mouse that has a scrolling wheel, you can also hold the Ctrl key on the keyboard while you scroll the wheel to increase or decrease the size of the page. Another thing you can do to make reading your inbox easier to increase your inbox spacing. This puts more white space between the messages, which is easier on your eyes. To do that, got to Settings and under Inbox spacing choose Large. You can always set it back to Small or Medium if that's your preference. Create Yahoo! Mail Messages Using a Larger Font To create emails in a larger font in Yahoo! Mail you'll need to tweak a display setting. It's an easy process: Start with your Yahoo! mail account open and select Settings in the upper-right corner. In the Settings menu that slides out from the right side of the page, select More Settings. On the Settings page that appears, select Writing Email. Use the drop-down menus below Default rich-text font to change the font type and size for the messages that you send. When you've finished making adjustments, select the Back to Inbox link to finish up. Yahoo! mail also has a Basic version. In the Basic version, you cannot control the size or type of font in any of your messages, even as you're creating them. You can still try zooming your browser windows to make things appear larger, but you can't actually change them.
