Wheelchair Ramp Slope Calculator for Safe Entry | Making Your Space Accessible

Did you know that over 3.3 million Americans use wheelchairs for mobility? Every one of them deserves safe and easy access to buildings. That's why getting your ramp's slope right isn't just about following rules, it's about creating a welcome space for everyone.

About Wheelchair Ramp Calculator

Think of a ramp slope like a hill. The steeper it is, the harder it becomes to climb. Our calculator helps you find the perfect balance between space and safety. Just like you wouldn't want to climb a mountain that's too steep, wheelchair users need gentle slopes they can navigate safely and independently.

How to Use the Calculator

Measure the height you need to reach in inches (this is the vertical distance from the ground to your entrance)
Enter this measurement in the "Height" box

Choose your desired slope ratio:

1:12 means for every inch of height, you need 12 inches of length (ADA standard)
1:16 gives an easier slope to navigate
1:20 creates the gentlest slope, perfect for manual wheelchair users

Understanding Your Results

The calculator shows you two important numbers:
Required Ramp Length: This tells you how long your ramp needs to be in both inches and feet
Slope Angle: This shows you the steepness of your ramp in degrees

Making Sense of the Numbers

Let's say you have a 30-inch height to your entrance. Using the ADA standard 1:12 ratio, you'll need a 360-inch (30 feet) ramp. This might seem long, but it ensures everyone can use it safely. Remember, gentler slopes (1:16 or 1:20) need more length but offer easier access.

Tips for Better Ramp Design

- Add landings (flat resting spots) every 30 feet of ramp length
- Include handrails on both sides
- Make sure the ramp is at least 36 inches wide
- Add non-slip surfaces for wet weather
- Consider adding lights for nighttime safety
