What is the maximum allowable slope for a wheelchair ramp?

1:10
1:12
1:14
1:16

The correct answer is: 1:12

The maximum allowable slope for a wheelchair ramp is 1:12. This means that for every 1 inch of vertical rise, there should be at least 12 inches of ramp run. This standard is established to ensure that ramps are accessible and safe for individuals using wheelchairs, allowing for a manageable ascent or descent. A slope of 1:12 is generally considered to provide a good balance between accessibility and space requirements, making it feasible for use in various environments, including homes and public buildings. Steeper slopes, such as 1:10, can be too challenging for many users, particularly those with limited strength or endurance. The 1:12 ratio reduces the risk of accidents and provides a more comfortable experience for users. The consideration for handicapped accessibility is crucial in construction, and adhering to the 1:12 slope guideline aligns with universal design principles and is often mandated by building codes and accessibility guidelines.
