1. What is a Ramp Gradient Calculator UK?

Definition: This calculator determines the gradient of a ramp according to UK standards, providing both decimal and ratio formats.

Purpose: It helps architects, builders, and accessibility planners design ramps that meet UK building regulations.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( G \) — Gradient (unitless decimal)
• \( H \) — Height difference (meters)
• \( L \) — Length of ramp (meters)

Explanation: The height is divided by the length to get the gradient, which is then converted to the UK standard ratio format (1:X).

3. Importance of Ramp Gradient Calculation

Details: Proper gradient calculation ensures ramps are accessible, safe, and compliant with UK regulations (typically 1:12 for wheelchair access).

4. Using the Calculator

Tips: Enter the height difference and ramp length in meters. Both values must be > 0. The calculator provides both decimal and ratio formats.

5. Frequently Asked Questions (FAQ)

Q1: What is the maximum gradient allowed for UK ramps?
A: For wheelchair access, the maximum gradient is typically 1:12 (8.33%), though 1:15 (6.67%) is preferred.

Q2: How is the UK ratio format different?
A: UK standards express gradients as ratios (1:X) where X is the horizontal run for 1 unit of rise.

Q3: When would I need a steeper gradient?
A: Steeper gradients (up to 1:10) may be used for short ramps where space is limited, but aren't suitable for wheelchair users.

Q4: Does this include landing requirements?
A: No, UK regulations also require level landings at top, bottom, and intervals - consult building codes for full requirements.

Q5: How do I convert between decimal and ratio formats?
A: Decimal = 1/X (e.g., 1:12 = 0.0833), Ratio = 1:(1/decimal) (e.g., 0.0833 = 1:12).
