The Seven Principles of Universal Design

1. Equitable Use
The design is useful and marketable to people with diverse abilities.
Example: Powered doors with sensors at entrances to public buildings that are convenient for all users.

2. Flexibility in Use
The design accommodates a wide range of individual preferences and abilities.
Example: Scissors designed for right or left-handed people

3. Simple and Intuitive Use
Use of the design is easy to understand, regardless of the user’s experience, knowledge, language skills, or current concentration level.
Example: an instructional manual with all drawings and no text

4. Perceptible Information
The design communicates necessary information effectively to the user, regardless of ambient conditions or the user’s sensory abilities.
Example: A large numbered thermostat with visual and audible cues

5. Tolerance for Error
The design minimizes hazards and the adverse consequences of accidental or unintended actions.
Example: a double-cut car key that can be inserted in either direction

6. Low Physical Effort
The design can be used efficiently and comfortably with a minimum of fatigue.
Example: touch lamps that operate without a switch

7. Size and Space for Approach and Use
Appropriate size and space is provided for approach, reach, manipulation, and use regardless of user’s body size, posture, or mobility.
Example: controls on the front of appliances and clear floor space around them
