![]() In situations where a handrail is not continuous, handrails must extend at least another 12” (30.5 cm) parallel to the flat surface of the ramp landing. The top grippable surface of any ramp handrail must be set at a height between 34”-38” (86.4-96.5 cm) above the ramp surface and a minimum clear width of 36” (91.4 cm) must be provided between handrails. Handrails along both sides of a ramp are required on any ramp system with a rise greater than 6” (15.2 cm) or a horizontal run greater than 72” (182.9 cm). Dimensions will vary based on the desired slope and height needed. The Ramp (Handrails - Vertical) has an overall combined height of 4.5’ (137 cm), total length of 18.5’ (5.64 m), and width of 45” (114.3 cm). The ends of any handrail should be rounded or returned smoothly to the floor, wall, or post. Inner handrails on a switchback or turned ramp must always be continuous. For edge protection, vertical guardrails are made up of a balustrades that must be spaced to continuously prevent the passage of a 4” (10.2 cm) diameter sphere. Vertical guardrails must double as both an assistive handrail and a guardrail that prevents users from accessing the edge of the ramp. Vertical ramp guardrails are common safety systems used for accessible ramps that combine required handrails with a guardrail made up of a series of vertical balustrades. Advances in materials and construction techniques have allowed for the development of lighter, more durable ramps that are easier to install and maintain. Since the passage of the ADA, ramps have become an essential component of accessible design and are used in a wide range of buildings and public spaces, including homes, schools, offices, and public transportation. In the 20th century, ramps became more widely used as a means of accessibility for people with disabilities. The concept of using inclined surfaces to join different levels can be traced back to ancient civilizations, such as the Greeks and Romans, who used ramps to access their buildings and structures. ![]() Low ramp slope ratios will require longer runs, while steeper slopes can have shorter lengths. The maximum slope of a ramp is calculated to provide comfortable and easy access to the building. Commonly used at the entrances of buildings to accommodate level changes from the exterior grade to the interior floor, ramps provide accessibility for wheelchair users, individuals with disabilities, and wheeled equipment. Ramps are inclined surfaces that join different levels of a space. ![]()
