1. What is the Disabled Ramp Gradient Calculator?

The Disabled Ramp Gradient Calculator helps determine the slope of a ramp based on vertical rise and horizontal run measurements. It specifically checks compliance with UK accessibility standards for disabled ramps.

2. How Does the Calculator Work?

The calculator uses the basic gradient formula:

\[ Gradient = \frac{Rise}{Run} \]

Where:

\( Rise \) — Vertical height difference (mm)
\( Run \) — Horizontal length of the ramp (mm)

Explanation: The gradient is expressed as both a ratio (1:X) and a percentage. The calculator also verifies if the ramp meets UK standards for maximum gradient.

3. UK Ramp Gradient Standards

Details: According to UK building regulations, the maximum gradient for short ramps is 1:12 (8.33%). For longer ramps or specific applications, different standards may apply.

4. Using the Calculator

Tips: Enter the vertical rise and horizontal run in millimeters. The calculator will display the gradient as both a ratio and percentage, and indicate UK compliance.

5. Frequently Asked Questions (FAQ)

Q1: What is the maximum gradient allowed for disabled ramps in the UK?
A: The maximum gradient for short ramps is 1:12 (8.33%). For ramps longer than 10 meters, a gentler gradient is recommended.

Q2: Why is 1:12 the maximum gradient?
A: This gradient provides a balance between accessibility and practicality, allowing wheelchair users to navigate the ramp safely without excessive effort.

Q3: Are there different standards for different types of ramps?
A: Yes, standards may vary for permanent vs temporary ramps, internal vs external ramps, and based on the intended users' mobility needs.

Q4: What other factors should be considered besides gradient?
A: Landing areas, handrails, surface texture, width, and edge protection are all important considerations for ramp design.

Q5: Is this calculator suitable for professional use?
A: While this calculator provides accurate gradient calculations, always consult current UK building regulations and accessibility standards for official compliance verification.
