1. What is the UK Ramp Standard?

The UK ramp standard specifies a maximum slope of 1:12 for accessible ramps, meaning for every 1 foot of vertical rise, there should be 12 feet of horizontal run.

2. How Does the Calculator Work?

The calculator uses the UK ramp formula:

Where:

• 1:12 — Standard slope ratio for accessible ramps in the UK
• Rise — Vertical height difference to be overcome
• Run — Required horizontal length of the ramp

3. Importance of Proper Ramp Calculation

Details: Correct ramp calculation ensures accessibility compliance, safety for wheelchair users, and meets building regulations.

4. Using the Calculator

Tips: Simply enter the vertical rise in feet to calculate the required run length for a 1:12 slope ramp.

5. Frequently Asked Questions (FAQ)

Q1: Is 1:12 the only acceptable slope for UK ramps?
A: While 1:12 is the standard for public access, steeper slopes may be permitted for private use with restrictions.

Q2: What's the maximum rise for a single ramp?
A: UK regulations typically recommend no more than 2m rise for a single ramp run before requiring a landing.

Q3: Are handrails required?
A: Yes, ramps with a rise greater than 600mm require handrails on both sides.

Q4: What about ramp width?
A: Minimum width is 1200mm for wheelchair access, though 1500mm is preferred for two-way traffic.

Q5: Are there exceptions to the 1:12 rule?
A: In existing buildings where space is limited, a maximum slope of 1:10 may be permitted for short rises.
