The required rise for ramps is:

Explanation:
Ramps are designed with a limit on steepness to keep them accessible and safe for wheelchair users. The standard maximum slope is 1:12, meaning for every 12 inches of horizontal run you rise 1 inch. This ratio provides a practical balance between space needs and ease of ascent. A slope of 1:20 is gentler and more comfortable, but it isn’t the required standard—it’s allowed when space permits, not mandatory. Slopes like 1:8 or 1:6 are too steep for safe, accessible use and wouldn’t meet typical accessibility requirements. So the required rise is 1:12.
