1. What is a Car Parking Ramp Slope Calculator?

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

Purpose: It helps architects, engineers, and construction professionals design parking ramps that meet safety standards and accessibility requirements.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( S \) — Slope (unitless ratio)
• \( Rise \) — Vertical height change
• \( Run \) — Horizontal distance

Explanation: The slope is calculated by dividing the vertical rise by the horizontal run, typically expressed as a ratio (e.g., 1:6).

3. Importance of Proper Ramp Slope

Details: Correct slope calculation ensures:

• Vehicle accessibility and safety
• Compliance with building codes (typically 1:6 to 1:8 slope)
• Proper drainage and water runoff
• Comfortable driving experience

4. Using the Calculator

Tips:

• Enter rise and run in the same units (feet, meters, etc.)
• Typical parking ramp slope is between 1:6 (16.67%) and 1:8 (12.5%)
• Maximum slope for ADA compliance is 1:12 (8.33%)

5. Frequently Asked Questions (FAQ)

Q1: What's the ideal slope for a parking ramp?
A: Most parking ramps use a slope between 1:6 and 1:8 (16.67% to 12.5%).

Q2: How do I measure rise and run?
A: Rise is the vertical height difference between ramp ends. Run is the horizontal distance between these points.

Q3: What's the maximum allowed slope?
A: Building codes typically limit parking ramps to 1:6 (16.67%) maximum slope for safety.

Q4: How does slope affect ramp length?
A: A gentler slope (e.g., 1:8) requires a longer ramp for the same elevation change than a steeper slope (1:6).

Q5: Can I use this for accessible ramps?
A: For ADA-compliant ramps, use a maximum 1:12 slope (8.33%). This calculator works for all slope types.
