Microsoft Word FAQs

When and how do I add a long description to an image, graph or chart?

In some instances, an image is too complex to describe in a few words. Charts and graphs are primary examples of such images. Although there does not appear to be any limit to the length of text in an “alt” attribute, “alt text” is meant to be relatively brief and to the point.

By including the long description in the graphic you will add information that can be used by all readers, not just those with disabilities. See how this is accomplished with an image of a graph:

Description: The above bar graph shows the percentage of total U.S. non-institutionalized population age 16-64 declaring one or more disabilities. The percentage value for each category is as follows: Total declaring one or more disabilities: 18.6 percent Sensory (visual and hearing): 2.3 percent Physical: 6.2 percent Mental: 3.8 percent Self-care: 1.8 percent Difficulty going outside the home: 6.4 percent Employment disability: 11.9 percent (Data retrieved from 2000 U.S. Census - external link)
