1. What is the Ramp Length Formula?

The ramp length formula calculates the actual length of a ramp using the Pythagorean theorem. It's essential for construction, accessibility planning, and slope design to ensure proper incline and safety standards.

2. How Does the Calculator Work?

The calculator uses the Pythagorean theorem:

Where:

• \( rise \) — Vertical height difference (ft)
• \( run \) — Horizontal distance (ft)
• \( length \) — Actual ramp length (ft)

Explanation: This formula calculates the hypotenuse of a right triangle formed by the vertical rise and horizontal run of the ramp.

3. Importance of Ramp Calculation

Details: Accurate ramp length calculation is crucial for ADA compliance, construction planning, wheelchair accessibility, and ensuring safe slope ratios in building design and landscaping projects.

4. Using the Calculator

Tips: Enter the vertical rise and horizontal run in feet. Both values must be non-negative numbers. The calculator will compute the actual ramp length needed.

5. Frequently Asked Questions (FAQ)

Q1: What is the maximum slope ratio for ADA compliant ramps?
A: ADA requires a maximum slope of 1:12, meaning for every 1 inch of rise, you need at least 12 inches of run.

Q2: How do I convert the result to other units?
A: To convert feet to meters, multiply by 0.3048. To convert feet to inches, multiply by 12.

Q3: Can this calculator be used for roof pitch calculations?
A: Yes, the same Pythagorean theorem applies to roof pitch calculations where rise represents the vertical height and run represents half the span.

Q4: What if I only know the angle of the ramp?
A: If you know the angle (θ) and either rise or run, you can use trigonometric functions: length = rise/sin(θ) or length = run/cos(θ).

Q5: Are there any limitations to this calculation?
A: This calculation assumes a straight ramp without curves or landings. For complex ramp designs with multiple segments, each straight section should be calculated separately.
