1. What is Ramp Length Calculation?

Ramp length calculation uses the Pythagorean theorem to determine the actual length of a ramp based on its horizontal run and vertical rise. This is essential for construction, accessibility planning, and various engineering applications.

2. How Does the Calculator Work?

The calculator uses the Pythagorean formula:

Where:

• \( \text{Run} \) — Horizontal distance (ft)
• \( \text{Rise} \) — Vertical height (ft)
• \( \text{Length} \) — Actual ramp length (ft)

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

3. Importance of Ramp Length Calculation

Details: Accurate ramp length calculation is crucial for proper ramp construction, ensuring ADA compliance, determining material requirements, and calculating slope ratios for accessibility.

4. Using the Calculator

Tips: Enter both run and rise measurements in feet. All values must be valid positive numbers. The calculator will compute the actual ramp length.

5. Frequently Asked Questions (FAQ)

Q1: What is the maximum slope for ADA compliant ramps?
A: ADA requires a maximum slope of 1:12 (1 inch rise per 12 inches run) for wheelchair ramps.

Q2: How do I calculate ramp slope?
A: Slope = Rise ÷ Run. Multiply by 100 to get percentage slope.

Q3: What are typical ramp length requirements?
A: For every 1 inch of rise, you typically need 12 inches of run for ADA compliance.

Q4: Can this calculator be used for roof pitches?
A: Yes, the same Pythagorean principle applies to calculating rafter lengths for roof construction.

Q5: What units should I use?
A: While this calculator uses feet, the formula works with any consistent unit of measurement.
