1. What is a 1:20 Ramp?

A 1:20 ramp is an inclined plane with a gentle slope where for every 1 unit of vertical rise, there are 20 units of horizontal run. This ratio is commonly used for wheelchair accessibility and other applications requiring gentle slopes.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Length \) — Ramp length (meters)
• \( Height \) — Vertical rise (meters)

Explanation: The 1:20 ratio means that for every meter of height, you need 20 meters of ramp length to maintain the proper slope.

3. Importance of Proper Ramp Slope

Details: Proper ramp slope is crucial for accessibility, safety, and compliance with building codes. A 1:20 slope is considered a gentle incline suitable for wheelchair users and those with mobility challenges.

4. Using the Calculator

Tips: Enter the vertical height in meters that needs to be overcome. The calculator will determine the required ramp length to maintain a 1:20 slope ratio.

5. Frequently Asked Questions (FAQ)

Q1: What does 1:20 slope mean?
A: A 1:20 slope means that for every 1 unit of vertical rise, the ramp extends 20 units horizontally.

Q2: Is 1:20 slope ADA compliant?
A: Yes, a 1:20 slope (5% grade) meets ADA requirements for accessible routes.

Q3: When is a 1:20 ramp appropriate?
A: This gentle slope is ideal for wheelchair ramps, stroller access, and situations where minimal exertion is desired.

Q4: Are there limitations to this calculation?
A: This calculates only the slope length. Actual ramp design should also consider landing platforms, handrails, and surface materials.

Q5: Can I use this for different units?
A: The calculator uses meters, but the ratio works with any consistent unit system (1 foot height requires 20 feet length).
