The maximum height for door handles, pulls, and latches above the finish floor is specified at 48 inches to ensure accessibility, particularly for individuals with disabilities in accordance with the Americans with Disabilities Act (ADA). This standard height facilitates ease of use by allowing a wide range of users, including those who may be in wheelchairs or of shorter stature, to reach and operate the door hardware without additional assistance. Keeping the hardware below this maximum height threshold promotes greater usability in public and commercial buildings, aligning with universal design principles.

Higher measurements such as 50, 52, or 54 inches would potentially exclude users who are unable to reach beyond the 48-inch mark, thus compromising accessibility standards set forth in building codes and guidelines for accessible design. Therefore, the selection of 48 inches as the maximum height is rooted in inclusivity and compliance with regulatory frameworks.
