The 7 Principles

The Seven Principles of Universal Design2, developed by the Centre for Universal Design, North Carolina State University, with a consortium of universal design researchers and practitioners from across the United States, are as follows:

Principle 1 – Equitable Design

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

Principle 2 – Flexibility in Use

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

Principle 3 – Simple and Intuitive

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

Principle 4 – Perceptible Information

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

Principle 5 – Tolerance for Error

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

Principle 6 – Low Physical Effort

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

Principle 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.
