Step-by-Step Guide to Choosing the Right Ramp Length and Slope
When installing a ramp for a home or public space, getting the measurements right is critical for both safety and ease of use. Whether you're accommodating a loved one using a mobility device or need to meet ADA (Americans with Disabilities Act) standards for public access, this guide will walk you through how to measure for the correct ramp length.
Step 1: Measure the Vertical Rise
Start by measuring the vertical rise, which is the height from the ground to the top surface you need to reach (such as a porch, step, or threshold).
-
Use a tape measure to record the straight vertical distance from the ground to the entry point.
-
This measurement, in inches, will help you determine the proper ramp length.
Step 2: Determine the Use Case
For Home Use (Residential Guidelines)
For residential applications, a steeper ramp is often acceptable—especially when space is limited or if a caregiver is available to assist.
-
Residential slope recommendation: 1:6 to 1:8
-
This means for every 1 inch of rise, plan for 6 to 8 inches of ramp length
Example:
If you have a 12-inch rise:
-
12 x 6 = 72 inches (6 feet)
-
12 x 8 = 96 inches (8 feet)
A ramp between 6 and 8 feet would be suitable depending on mobility needs and whether assistance is available.
Best for:
Private homes, temporary ramps, or short distances
For ADA-Compliant Use (Public/Commercial Spaces)
If you’re installing a ramp for public or commercial use—or for long-term accessibility at home—ADA guidelines must be followed.
-
ADA-required slope: 1:12
-
This means for every 1 inch of rise, you need 12 inches (1 foot) of ramp length
Example:
If you have a 24-inch rise:
-
24 x 12 = 288 inches
-
288 ÷ 12 = 24 feet of ramp
Best for:
Businesses, public buildings, schools, long-term home installations
Step 3: Consider Space and Accessibility Needs
Before purchasing or installing your ramp, take into account:
-
Available space for a straight or turning layout
-
Entryway width to ensure the ramp fits door openings or thresholds
-
Need for platforms (required for rises over 30 inches in ADA-compliant settings)
-
Mobility equipment used (scooter, wheelchair, walker) and turning radius
