1. What is a Ramp Length Calculator for Australia?

Definition: This calculator determines the required ramp length based on Australian accessibility standards (1:14 gradient).

Purpose: It helps builders, architects, and property owners comply with Australian disability access requirements.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( L \) — Ramp length (meters)
• \( H \) — Height difference (meters)

Explanation: Australian standards require a 1:14 gradient for wheelchair access ramps, meaning for every 1m of height, you need 14m of ramp length.

3. Importance of Ramp Length Calculation

Details: Proper ramp length ensures accessibility compliance, safety for wheelchair users, and meets Australian building codes.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why 1:14 gradient?
A: This is the maximum gradient allowed for wheelchair access ramps under Australian standards (AS 1428.1).

Q2: Are there exceptions to this rule?
A: Yes, for existing buildings where space is limited, a 1:8 gradient may be permitted with additional safety features.

Q3: Does this include landing requirements?
A: No, additional length is needed for landings (every 9m of ramp length requires a 1.2m landing).

Q4: What about handrails?
A: Handrails are required on both sides for ramps steeper than 1:20 under Australian standards.

Q5: How does this compare to other countries?
A: Australia's 1:14 is more lenient than the US ADA standard of 1:12 but stricter than UK's 1:15.
