1. What is the Australian Ramp Standard?

The Australian standard for ramps specifies a maximum gradient of 1:8 for accessible ramps, meaning for every 1 meter of vertical rise, the ramp must extend 8 meters horizontally.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Length \) — Required ramp length in meters
• \( Height \) — Vertical rise in meters
• \( 8 \) — Standard gradient ratio (1:8)

Explanation: This calculation ensures compliance with Australian accessibility standards for wheelchair ramps.

3. Importance of Correct Ramp Length

Details: Proper ramp length is crucial for accessibility, safety, and compliance with Australian building codes (AS 1428.1). Too steep ramps can be dangerous for wheelchair users and people with mobility impairments.

4. Using the Calculator

Tips: Enter the vertical height in meters that needs to be overcome by the ramp. The calculator will determine the minimum required ramp length according to Australian standards.

5. Frequently Asked Questions (FAQ)

Q1: Is 1:8 the only acceptable gradient in Australia?
A: While 1:8 is the standard maximum gradient, steeper gradients may be allowed in certain circumstances with appropriate landings and safety features.

Q2: Are there requirements for ramp width?
A: Yes, Australian standards require a minimum clear width of 1 meter for accessible ramps.

Q3: Do I need handrails?
A: Handrails are required on both sides for ramps with a rise greater than 300mm or a horizontal projection greater than 1.5m.

Q4: What about landings?
A: Ramps must have level landings at least 1.2m long at the top and bottom, and intermediate landings every 9m of ramp run.

Q5: Are there different requirements for existing buildings?
A: Existing buildings may have different compliance requirements under the Disability (Access to Premises - Buildings) Standards 2010.
