1. What is a Slope Calculator for Ramps?

Definition: This calculator determines the slope of a ramp based on its vertical rise and horizontal run.

Purpose: It helps architects, builders, and DIYers ensure their ramps meet accessibility standards and safety requirements.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Slope — Ratio of vertical to horizontal distance (unitless)
• Rise — Vertical height change (any units)
• Run — Horizontal distance (same units as rise)

Explanation: The slope is calculated by dividing the vertical rise by the horizontal run.

3. Importance of Proper Ramp Slope

Details: Correct slope ensures accessibility (typically 1:12 max for ADA compliance), safety, and usability of ramps.

4. Using the Calculator

Tips: Enter the vertical rise and horizontal run in consistent units. The calculator provides both ratio and percentage slope.

5. Frequently Asked Questions (FAQ)

Q1: What's the maximum slope for an ADA compliant ramp?
A: 1:12 slope (8.33%) is the maximum for ADA compliance.

Q2: How do I convert slope ratio to degrees?
A: Use arctangent: degrees = arctan(rise/run). We may add this feature in future updates.

Q3: What units should I use?
A: Any consistent units (inches, feet, meters) as long as rise and run use the same units.

Q4: What's the difference between slope ratio and percentage?
A: Ratio is rise:run (e.g., 1:12), percentage is (rise/run)×100 (e.g., 8.33%).

Q5: How does slope affect ramp design?
A: Steeper slopes require more effort to climb and may not meet accessibility standards.
