1. What is Ramp Length Calculation?

Ramp length calculation determines the required length of a ramp based on the vertical rise and the angle of inclination. This is essential for designing accessible ramps, wheelchair access, and various construction projects.

2. How Does the Calculator Work?

The calculator uses the trigonometric formula:

Where:

• \( Length \) — Ramp length in meters
• \( Rise \) — Vertical height in meters
• \( \theta \) — Angle of inclination in degrees

Explanation: The formula calculates the hypotenuse of a right triangle where the rise is the opposite side and the ramp length is the hypotenuse.

3. Importance of Ramp Length Calculation

Details: Proper ramp length calculation ensures accessibility compliance, safety standards, and optimal slope for wheelchair users and pedestrians. It's crucial for building codes and ADA requirements.

4. Using the Calculator

Tips: Enter the vertical rise in meters and the angle in degrees (between 0 and 90). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the maximum recommended ramp angle?
A: For wheelchair accessibility, the maximum recommended slope is 1:12 (approximately 4.76 degrees). Steeper slopes may require assistance.

Q2: How do I convert degrees to slope ratio?
A: Slope ratio = 1 : tan(θ). For example, 4.76° ≈ 1:12 slope.

Q3: What are ADA requirements for ramp length?
A: ADA requires a maximum slope of 1:12, meaning for every 1 inch of rise, you need 12 inches of ramp length.

Q4: When should I use landings in ramp design?
A: Landings are required every 30 feet (9 meters) of ramp length and at the top and bottom of each ramp run.

Q5: Can this calculator be used for vehicle ramps?
A: Yes, but vehicle ramps typically have different angle requirements based on the vehicle type and usage.
