1. What is an Enable Access Ramp Calculator?

Definition: This calculator determines the required length of a wheelchair ramp based on the height difference that needs to be overcome.

Purpose: It helps designers, builders, and property owners create accessible ramps that comply with the standard 1:20 slope ratio.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( L \) — Length of ramp (meters)
• \( H \) — Height difference to overcome (meters)

Explanation: The 1:20 ratio means for every 1 meter of vertical rise, you need 20 meters of horizontal run.

3. Importance of Proper Ramp Calculation

Details: Correct ramp length ensures accessibility compliance, safety for wheelchair users, and meets building code requirements.

4. Using the Calculator

Tips: Simply enter the height difference in meters that needs to be overcome by the ramp. The calculator will determine the minimum required length.

5. Frequently Asked Questions (FAQ)

Q1: Why is the 1:20 ratio important?
A: This slope is the maximum recommended for wheelchair accessibility, allowing safe and comfortable use without being too steep.

Q2: What if I can't accommodate a 1:20 ramp?
A: For steeper slopes (up to 1:12), you may need to add resting platforms and handrails, but 1:20 is ideal for independent wheelchair use.

Q3: Does this include landing areas?
A: No, additional space should be allocated for level landings at the top, bottom, and any turns in the ramp.

Q4: How does this apply to multiple steps?
A: Measure the total vertical rise from the lowest to highest point - the calculation is the same regardless of intermediate steps.

Q5: What about ramps for vehicles?
A: Vehicle ramps typically use steeper slopes (1:4 to 1:6) as they're not designed for wheelchair access.
