1. What is a Car Ramp Length Calculator?

Definition: This calculator determines the actual length of a car ramp based on its vertical rise and horizontal run using the Pythagorean theorem.

Purpose: It helps vehicle owners, mechanics, and construction professionals design safe and properly angled ramps for cars and other vehicles.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( L \) — Actual ramp length (feet or meters)
• \( rise \) — Vertical height (feet or meters)
• \( run \) — Horizontal distance (feet or meters)

Explanation: The formula calculates the hypotenuse of a right triangle formed by the ramp's rise and run.

3. Importance of Proper Ramp Length

Details: Correct ramp length ensures safe vehicle angles (typically 1:6 to 1:4 slope), prevents scraping, and provides comfortable access.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What's a typical car ramp slope?
A: Most vehicle ramps use a slope between 1:6 (gentle) to 1:4 (steeper), meaning 1 unit of rise per 4-6 units of run.

Q2: How do I measure rise and run?
A: Rise is the vertical height difference between ground and platform. Run is the horizontal distance the ramp will cover.

Q3: Does this work for wheelchair ramps?
A: Yes, but wheelchair ramps typically require gentler slopes (1:12) and different safety considerations.

Q4: What if I only know the angle?
A: Use rise = run × tan(angle). We may add an angle-based calculator in future versions.

Q5: Should I add extra length for safety?
A: It's recommended to add 6-12 inches to the calculated length for approach and departure transitions.
