In general, for text in electronic or print documents, 14 point size is considered the minimum acceptable size for large print. If your documents permit, 16 point text is recommended.
A non-serif font, such as Arial, is recommended because when magnified, the serifs in fonts do not smooth very well and text looks very blocky.
Try not to use background images or watermarks in emails as these can clutter the screen and make it hard for those using magnification products to discern the text from the background.
When typing acronyms, use all caps such as USPS instead of usps so that JAWS will do a better job of reading them properly.
When you type email addresses or other words that are joined together without spaces between them capitalize the first letter of each word. JAWS reads text with mixed case as if it were separate words.
To adjust your default font and point size in Word:
Make effective use of headings and other native Word formatting within Word documents. A JAWS user can switch a document to outline view and very easily get an overview of a document if headings are used well. This also makes it easier to move from one section to another quickly in a document.
For JAWS users, being able to look at attachments to an email depends on how the originator sets up their email. The worst possible way to use Outlook with attachments is to have your email set up to create Rich Text email messages. Change your preferences to either plain text or HTML messages. Here’s how in Outlook:
Another optional change you might wish to make is to get rid of the prefix “greater than” sign (>) that precedes the text of the replied to message. This makes for less irritating reading for JAWS users.
Put instructions near the top of the document. If the document is large, use a pair of asterisks (**) to mark the different sections of the document. Users can press CTRL+F to open the find dialog box and use F3 after that to find the different sections by searching for the pairs of asterisks throughout the document.
In case the document were to be converted to Braille by the reader you can force the Braille embosser to insert a blank line between sections of the Braille document by including two (2) blank lines in the text document at key places.
Put a table of contents near the top of the document when possible.
Use periods or semicolons frequently to punctuate the document with pauses, so that JAWS does not run text together when it is being read. Having pauses between phrases can make it easier for people to understand the content of the document.
