California IDEX Practice Exam

The required height range for a handrail in barrier-free design is typically 34" to 38". This range is aligned with guidelines set by the Americans with Disabilities Act (ADA), ensuring that handrails are accessible for individuals of varying heights and abilities. By maintaining this height, handrails provide adequate support for users, enhancing safety and usability in public and private spaces. In the context of barrier-free design, having handrails within this specific height range helps accommodate users who may be navigating stairs, ramps, or other areas where stability and support are needed. A handrail that is too low or too high may not be easy for users to grasp or may fail to provide the necessary support, significantly impacting the safety of individuals with mobility challenges.
