1. What is Slope?

Slope is a measure of the steepness or incline of a surface, calculated as the ratio of vertical change (rise) to horizontal change (run). For handicap ramps, proper slope calculation is essential for accessibility and safety.

2. How Does the Calculator Work?

The calculator uses the slope formula:

Where:

• \( Rise \) — Vertical change (in units like meters or feet)
• \( Run \) — Horizontal change (in units like meters or feet)

Explanation: The slope represents how much vertical elevation changes per unit of horizontal distance.

3. Importance of Slope Calculation

Details: Accurate slope calculation is crucial for designing accessible handicap ramps that meet safety standards and provide comfortable access for people with mobility challenges.

4. Using the Calculator

Tips: Enter rise and run values in consistent units (both in meters or both in feet). Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the recommended slope for handicap ramps?
A: The ADA recommends a maximum slope of 1:12 (8.33%) for handicap ramps, meaning 1 unit of rise for every 12 units of run.

Q2: Can I use different units for rise and run?
A: No, both measurements must use the same units for accurate slope calculation.

Q3: What if my run measurement is zero?
A: Run cannot be zero as division by zero is undefined. A valid run value must be greater than zero.

Q4: How precise should my measurements be?
A: For accessibility applications, measurements should be precise to ensure the ramp meets legal requirements and safety standards.

Q5: Can this calculator be used for other slope applications?
A: Yes, while designed for handicap ramps, this calculator can be used for any slope calculation where you need to determine the ratio of vertical to horizontal change.
