Seven Guidelines for Universal Web Design

To better illustrate the tenets of universal Website design, the Center for Universal Design at North Carolina State University established seven guiding principles:

• Equitable use

  The design is useful and marketable to people with diverse abilities.

• Flexibility in use

  The design accommodates a wide range of individual preferences and abilities.

• Simple and intuitive

  Use of the design is easy to understand, regardless of the user's experience, knowledge, language skills, or concentration level.

• Perceptible information

  The design communicates necessary information effectively to the user, regardless of ambient conditions or the user's sensory abilities.

• Tolerance for error

  The design minimizes hazards and the adverse consequences of accidental or unintended actions.

• Low physical effort

  The design can be used efficiently and comfortably, and with a minimum of fatigue.

• Size and space for approach and use

  Appropriate size and space is provided for approach, reach, manipulation, and use regardless of the user's body size, posture, or mobility.
