Principle Seven: 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.
Guidelines:
Provide a clear line of sight to important elements for any seated or standing user.
Make reach to all components comfortable for any seated or standing user.
Accommodate variations in hand and grip size.
Provide adequate space for the use of assistive devices or personal assistance
(Story et al., 1998, p.44).

The sufficient and enough space that is designed to enable everybody to use the design is the clear explanation of this principle.


An example of car parking area disabling easy access and use because of inadequate space (Atatürk Bulvarı, Ankara)


An example of pavement that cannot be used becasue of inadequate space (Kocatepe, Ankara)


In the first photograph the problem is that the parking area being not wide enough. And in the second photograph the pavement is not designed in terms of human scale. It is too narrow that even one person cannot pass comfortably.
