Most businesses will need to meet ADA standards for their ramps. ADA requires a 1:12 ratio, which works out to 1 foot of ramp for each inch of rise. For example, a 20 inch rise will require a 20 foot ramp. Additional, ADA limits the longest single span of ramp, prior to a rest or turn platform to 30 feet. Ramps can be as long as needed, but no single run of ramp can exceed 30 feet.
Residential Applications usually will not be required to meet ADA standards (ADA is a commercial code). For Residential use, it is usually recommended not to exceed a 2:12 ratio, which work out to 1 foot of ramp for each 2 inches in rise. For example, a 20 inch rise should apply a 10 foot or longer ramp. The longer the ramp, the more gentle the slope should be, seeing as ramps are focused on maximum ease when travelling.

Famous quotes containing the word length:
“And my spirit is grown to a lordly great compass within,
That the length and the breadth and the sweep of the marshes of
Glynn
Will work me no fear like the fear they have wrought me of yore
When length was failure, and when breadth was but bitterness sore,
And when terror and shrinking and dreary unnamable pain
Drew over me out of the merciless miles of the plain,—
Oh, now, unafraid, I am fain to face
The vast sweet visage of space.”
—Sidney Lanier (1842–1881)
“Rivers must have been the guides which conducted the footsteps of the first travelers. They are the constant lure, when they flow by our doors, to distant enterprise and adventure; and, by a natural impulse, the dwellers on their banks will at length accompany their currents to the lowlands of the globe, or explore at their invitation the interior of continents.”
—Henry David Thoreau (1817–1862)
“At length to hospital
This man was limited,
Where screens leant on the wall
And idle headphones hung.
Since he would soon be dead
They let his wife come along
And pour out tea, each day.”
—Philip Larkin (1922–1986)
