Ramps look simple. They're not. Slope, surface, weight rating, and storage all matter — and a ramp that's too steep is more dangerous than no ramp at all.

The 1:12 rule

ADA guidance calls for one foot of ramp for every inch of rise. A 6-inch step needs 6 feet of ramp. Anything steeper than 1:12 is unsafe for unassisted use, and steeper than 2:12 (1:6) is unsafe even with help.

Threshold ramps

Rubber or aluminum wedges, 1–4 inches tall. The fix for a single doorway lip. $40–$200.
