Principles of Universal Design

• Equitable Use: The design does not disadvantage or stigmatize any group of users.
• Flexibility in Use: The design accommodates a wide range of individual preferences and abilities.
• Simple, Intuitive Use: Use of the design is easy to understand, regardless of the user's experience, knowledge, language skills, or current 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 & Use: Appropriate size and space is provided for approach, reach, manipulation, and use, regardless of the user's body size, posture, or mobility.
