1. What is a Ramp Calculator UK?

Definition: This calculator determines the required ramp length based on height and slope ratio according to UK accessibility standards.

Purpose: It helps architects, builders, and property owners design accessible ramps that comply with UK building regulations.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( L \) — Ramp length (meters)
• \( H \) — Height difference (meters)
• \( S \) — Slope ratio (e.g., 12 for 1:12 slope)

Explanation: The height is multiplied by the slope ratio to determine the required ramp length for safe and comfortable access.

3. UK Ramp Standards

Details: UK building regulations typically require:

• Maximum slope of 1:12 for wheelchair access
• 1:15 preferred for public buildings
• 1:20 for longer ramps where space permits

4. Using the Calculator

Tips: Enter the height difference in meters and the second number of the slope ratio (default 12 for 1:12). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the maximum slope allowed in the UK?
A: The maximum recommended slope is 1:12, with 1:15 preferred for public access.

Q2: Do I need handrails for ramps?
A: UK regulations require handrails on both sides for ramps steeper than 1:20 or longer than 2 meters.

Q3: What about landing platforms?
A: Ramps longer than 5 meters require intermediate landing platforms at least 1.2m long.

Q4: Can I use a steeper slope for private residences?
A: While 1:12 is the maximum, 1:15 is strongly recommended even for private homes.

Q5: How does this differ from US standards?
A: The UK generally requires gentler slopes than the US (1:12 UK vs 1:8-1:10 US for private spaces).
