The most common mistake made by first-time
ramp users is trying to use a ramp that is not long enough for
safe and comfortable usage. In general, ramp designers and architects
recommend a SLOPE of 1:12, or a 5 degree incline. This translates
to a maximum slop of 1” RISE for every 12” of RUN (length).
The ADA requires a platform after every
30 feet run of ramp and a 60” level landing at the top and
bottom of a ramp run. If you are using a power chair or scooter
it is important to note that even motorized equipment can experience
power reductions and/or battery drains when put in extreme slope
or angle conditions, so it is important to design rest areas for
both humans and machines, aw well as adequate sized platforms for
an adequate turning radius.
