What is the preferred height for doorknobs and other door hardware for PWD use?

The preferred height for doorknobs and other door hardware for persons with disabilities (PWD) use is generally set at 900 mm. This measurement is in alignment with accessibility standards and guidelines that aim to ensure ease of use for individuals with various mobility challenges. Installing hardware at this height allows easier reach and operation for wheelchair users and those with limited upper body strength.

Standards like the Americans with Disabilities Act (ADA) have established specific recommendations for the height of accessible hardware. This helps to create an inclusive environment, ensuring that all individuals can access and operate doors comfortably and independently. The choice of 900 mm strikes a balance between usability for a wide range of users, adhering to best practices in design for accessibility.
