1. What Is Ramp Slope?

Ramp slope refers to the steepness of a ramp, typically expressed as a ratio (e.g., 1:14) or percentage. In Australia, the maximum allowable slope for accessible ramps is 1:14 according to AS 1428 design standards.

2. How Does The Calculator Work?

The calculator uses standard slope calculation formulas:

Where:

• \( Rise \) — Vertical height difference (mm)
• \( Run \) — Horizontal length (mm)

Explanation: The calculator determines if your ramp design meets Australian Standard AS 1428 requirements for accessibility.

3. Importance Of Slope Calculation

Details: Proper ramp slope calculation is essential for wheelchair accessibility, building code compliance, and ensuring safe and comfortable access for people with mobility limitations.

4. Using The Calculator

Tips: Enter rise and run measurements in millimeters. Ensure accurate measurements for reliable results. The calculator will determine compliance with Australian accessibility standards.

5. Frequently Asked Questions (FAQ)

Q1: What is the maximum slope allowed in Australia?
A: The maximum slope for accessible ramps is 1:14 (approximately 7.14%) according to AS 1428.1 design standards.

Q2: When is a ramp required instead of stairs?
A: Ramps are required wherever there is a change in level greater than 35mm to ensure accessibility for wheelchair users and people with mobility aids.

Q3: Are there exceptions to the 1:14 rule?
A: For existing buildings where space is limited, a slope of 1:12 may be permitted for short distances, but 1:14 is preferred for new construction.

Q4: What other requirements apply to ramps?
A: Ramps require appropriate landings, handrails, edge protection, and adequate width (minimum 1000mm clear) according to Australian standards.

Q5: How do I measure rise and run accurately?
A: Measure rise vertically from start to finish point, and run horizontally along the ramp length. Use precise measuring tools for best results.
