1. What is a Ramp Length Calculator?

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

Purpose: It helps architects, builders, and DIYers determine the proper ramp length for construction projects, accessibility ramps, or any inclined surface.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( L \) — Length of the ramp (units)
• \( rise \) — Vertical height difference (units)
• \( run \) — Horizontal distance (units)

Explanation: The formula calculates the hypotenuse of a right triangle where the rise and run form the other two sides.

3. Importance of Ramp Length Calculation

Details: Proper ramp length ensures safety, accessibility compliance, and comfortable slope for users. It's crucial for ADA compliance and construction planning.

4. Using the Calculator

Tips: Enter the vertical rise and horizontal run in consistent units (feet, meters, etc.). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the maximum slope for an ADA compliant ramp?
A: ADA requires a maximum slope of 1:12 (1 inch rise per 12 inches run).

Q2: How do I measure rise and run?
A: Rise is the vertical height difference between start and end points. Run is the horizontal distance between these points.

Q3: Can I use different units for rise and run?
A: No, both measurements must use the same units for accurate results.

Q4: Does this account for ramp landings?
A: No, this calculates only the sloped portion. Add landing lengths separately.

Q5: How does this relate to ramp angle?
A: The angle can be calculated as arctan(rise/run), but this calculator focuses on length.
