1. What is Ramp Slope Calculation?

Ramp slope calculation determines the angle of inclination of a ramp using the vertical rise and horizontal run measurements. This is essential for ensuring ramps meet accessibility standards and safety requirements.

2. How Does the Calculator Work?

The calculator uses the trigonometric formula:

Where:

• \( \theta \) — Ramp slope angle in degrees
• \( \text{rise} \) — Vertical change (height difference)
• \( \text{run} \) — Horizontal change (length)
• \( \arctan \) — Inverse tangent function

Explanation: The formula calculates the angle whose tangent equals the ratio of vertical rise to horizontal run.

3. Importance of Ramp Slope Calculation

Details: Proper ramp slope calculation is crucial for accessibility compliance, wheelchair safety, building code adherence, and ensuring comfortable use for people with mobility challenges.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is the maximum recommended ramp slope?
A: For wheelchair accessibility, the maximum recommended slope is 1:12 (4.76 degrees) according to ADA guidelines.

Q2: How do I measure rise and run accurately?
A: Measure rise vertically from the lowest to highest point, and run horizontally along the ramp's base length.

Q3: Can I use different units for rise and run?
A: No, both measurements must use the same units since the calculation involves a ratio.

Q4: What's the difference between slope ratio and slope angle?
A: Slope ratio (e.g., 1:12) expresses the relationship between rise and run, while slope angle gives the inclination in degrees.

Q5: When is this calculation most important?
A: This calculation is critical for construction projects, accessibility modifications, and any situation requiring safe ramp design.
