Accessibility · Defined
Reach range
The vertical and horizontal extent within which an operable element must be located for accessible use under the applicable criteria.
Why it matters
Forward and side approaches, obstructions, and element type affect the analysis. Mounting height alone may be insufficient where a counter blocks access.
In practice
A project example
A control is within a nominal height range but is set too far behind an obstruction.
