What is the steepest a ramp can be?

the U.S. per the US ADA (Americans with Disabilities Act), a ramp is a sloping route constructed with a slope greater than 1:20 (one inch of vertical rise for every 20 inches of horizontal length, or run) and must conform to the standard ADA specifications for ramps. Ramps may have a maximum slope of 1:12.

What is the maximum slope for walking?

The slope is one inch vertically for every 16 inches horizontally. The maximum good slope is easily manageable by both people walking and wheelchair users, so I think it is. The ADA requires that ramps rise no higher than 30 inches.

What is the max slope for a handicap ramp?

What slope is a handicap ramp?

The ADA provides good direction about ratios for wheelchair ramp slopes. The commercial and public facility standard for slope is 1:12 (in inches) or about 5 degrees of incline. For those building ramps at home, the ratio can be as steep as 3:12 or almost 15 degrees.

How steep is a green ski run?

The steepness of ski trails is usually measured by grade (as a percentage) instead of degree angle. In general, beginner slopes (green circle) are between 6% and 25%. Intermediate slopes (blue square) are between 25% and 40%. Difficult slopes (black diamond) are 40% and up.

How steep is a red run?

Red runs are steep, they typically have a gradient range of 30-45% and they are steeper than blue runs and considerably steeper than green runs. The beginning of red runs can be deceptive and they often start on shallow sections and then turn into much steeper sections later on.

How steep is a blue ski run?

Blue runs vary by difficulty depending on the resort you're skiing at and the area of the country you're in (steepness can range from 25 to 40 degrees), but for the most part, you're unlikely to find moguls or long pitches of super-steep terrain.
