1. What is a Slope Of A Ramp Calculator?

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

Purpose: It helps architects, builders, and accessibility planners ensure ramps meet required slope standards for safety and compliance.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Slope — The incline percentage of the ramp
• Rise — Vertical height change (units)
• Run — Horizontal length (units)

Explanation: The ratio of vertical rise to horizontal run is multiplied by 100 to convert it to a percentage.

3. Importance of Ramp Slope Calculation

Details: Proper slope calculation ensures ramps are safe, accessible, and compliant with building codes (typically 8.33% max for ADA compliance).

4. Using the Calculator

Tips: Enter the vertical rise and horizontal run in consistent units (both in feet, meters, etc.). All values must be > 0.

5. Frequently Asked Questions (FAQ)

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

Q2: How do I measure rise and run?
A: Rise is the vertical height difference from start to end. Run is the horizontal distance covered.

Q3: What units should I use?
A: Use any consistent units (feet, meters, inches) as long as both rise and run are in the same unit.

Q4: What slope is too steep for a wheelchair ramp?
A: Generally, slopes above 10% become difficult for manual wheelchair users.

Q5: How does slope relate to angle?
A: Slope percentage = tan(angle) × 100. A 45° angle equals 100% slope.
