1. What is the Ramp Length Formula?

The ramp length formula calculates the actual length of a ramp using the Pythagorean theorem. It determines the diagonal distance of a ramp based on its vertical rise and horizontal run.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( rise \) — Vertical change in feet
• \( run \) — Horizontal change in feet

Explanation: This formula applies the Pythagorean theorem to calculate the hypotenuse of a right triangle, where the rise and run form the two perpendicular sides.

3. Importance of Ramp Length Calculation

Details: Accurate ramp length calculation is essential for construction projects, accessibility compliance, and determining material requirements for ramp installation.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between rise and run?
A: Rise is the vertical height the ramp needs to overcome, while run is the horizontal distance covered by the ramp.

Q2: What is the recommended slope for accessibility ramps?
A: For ADA compliance, the maximum slope should be 1:12 (1 inch of rise per 12 inches of run).

Q3: Can this calculator be used for any ramp type?
A: Yes, this formula works for any straight ramp regardless of material or purpose.

Q4: How accurate is this calculation?
A: The calculation is mathematically precise for straight ramps. For curved ramps, additional calculations would be needed.

Q5: Does this account for ramp thickness or landing areas?
A: No, this calculates only the sloped surface length. Additional length for landings or thickness should be calculated separately.
