Disabled Ramp Formula:
| From: | To: |
The UK Disabled Ramp Calculation determines the required length of a ramp based on the maximum permitted slope of 1:12 (1 unit of rise for every 12 units of run) as specified in UK accessibility guidelines and building regulations.
The calculator uses the simple formula:
Where:
Explanation: This calculation ensures wheelchair accessibility by maintaining the maximum permitted slope of 1:12 as required by UK building regulations.
Details: Maintaining the correct 1:12 slope ratio is crucial for wheelchair accessibility, safety, and compliance with UK disability access regulations. Proper ramp design ensures ease of use for people with mobility impairments.
Tips: Enter the vertical rise in meters. The calculator will determine the minimum required ramp length to maintain the 1:12 slope ratio. Always ensure the rise value is positive and reasonable for practical ramp construction.
Q1: Why is the 1:12 slope ratio used in the UK?
A: The 1:12 ratio is specified in UK building regulations as the maximum slope for accessible ramps, ensuring safe and comfortable use for wheelchair users and people with mobility impairments.
Q2: Are there exceptions to the 1:12 rule?
A: For very small rises (under certain thresholds), slightly steeper slopes may be permitted, but 1:12 is the standard requirement for most applications.
Q3: What about landings and handrails?
A: This calculator only determines ramp length. UK regulations also require appropriate landings, handrails, and other safety features for compliant ramp design.
Q4: Can this calculator be used for commercial buildings?
A: Yes, the 1:12 slope requirement applies to both residential and commercial properties under UK accessibility regulations.
Q5: What units should I use?
A: The calculator uses meters for both rise and length, consistent with UK building standards and metric measurements.
