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 can 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 might need to go to the Settings menu to find the Zoom controls. Zoom controls allow you to make everything in the browser display larger. Of course, this change will also make everything on pages you visit other than Yahoo! Mail larger, as well.

Change Yahoo! Mail Inbox Spacing
Another thing you can do to make reading your inbox more comfortable is to increase your inbox spacing. Increased spacing puts more white space between the messages, which is easier on your eyes.
