1. What Is Ramp Gradient?

Ramp gradient is a measure of the steepness of a slope, expressed as a ratio of horizontal distance (run) to vertical height (rise). For disabled access ramps, specific gradient requirements ensure safety and accessibility.

2. How Does The Calculator Work?

The calculator uses the gradient formula:

Where:

• \( run \) — Horizontal distance (in consistent units)
• \( rise \) — Vertical height (in consistent units)

Explanation: The formula calculates the ratio of horizontal distance to vertical rise, which determines the steepness of the ramp.

3. Importance Of Gradient Calculation

Details: Proper gradient calculation is essential for designing accessible ramps that comply with disability access regulations and ensure safe, comfortable use for wheelchair users and people with mobility impairments.

4. Using The Calculator

Tips: Enter both run and rise values in the same units (meters, feet, etc.). Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the maximum gradient for disabled ramps?
A: Most accessibility standards recommend a maximum gradient of 1:12 (1 unit rise per 12 units run) for wheelchair ramps.

Q2: Why is gradient expressed as a ratio?
A: The ratio format (e.g., 1:12) clearly communicates the relationship between horizontal and vertical components, making it easy to understand steepness.

Q3: Can I use different units for run and rise?
A: No, both values must be in the same units for the ratio to be meaningful and accurate.

Q4: What if my rise is greater than my run?
A: This would create a very steep ramp that would not be suitable for disabled access and likely wouldn't meet accessibility standards.

Q5: Are there other factors to consider besides gradient?
A: Yes, proper ramp design also considers landing areas, handrails, surface texture, and width to ensure complete accessibility and safety.
