One of the keys to make your website more accessibility is to understand how people with various disabilities use the web.  The Home Office Digital Team at gov.uk has created a great set of posters on designing for accessibility that includes a wide range of users. The set contains posters on:

• Designing for users on the autistic spectrum
• Designing for users of screen readers
• Designing for users with low vision
• Designing for users with dyslexia
• Designing for users with physical or motor disabilities
• Designing for users who are deaf or hard of hearing
• Designing for users with anxiety

The posters are available through a creative commons licence. Here is the full accessibility-posters-set (PDF). I plan on printing these posters for our office suite which will be a great reminder on the inclusive approach to web design.
