1. What is Ramp Slope?

Ramp slope represents the steepness of a ramp, calculated as the ratio of vertical rise to horizontal run. It's essential for accessibility compliance, construction standards, and safety considerations in architectural design.

2. How Does the Calculator Work?

The calculator uses the slope formula:

Where:

• \( Rise \) — Vertical height difference (meters)
• \( Run \) — Horizontal distance (meters)

Output Options:

• Ratio: Expressed as 1:X (e.g., 1:12)
• Percentage: Expressed as percentage (e.g., 8.33%)

3. Importance of Slope Calculation

Details: Proper slope calculation ensures ramps meet accessibility standards (ADA, building codes), provides safe and comfortable use for wheelchair users, and prevents accidents due to excessive steepness.

4. Using the Calculator

Tips: Enter rise and run values in meters. Both values must be positive numbers greater than zero. Select your preferred output format (ratio or percentage).

5. Frequently Asked Questions (FAQ)

Q1: What is the maximum slope for wheelchair ramps?
A: ADA standards recommend 1:12 slope (8.33%) maximum for commercial ramps. Residential ramps may vary by local codes.

Q2: How do I convert between ratio and percentage?
A: Ratio to percentage: (1/ratio) × 100. Percentage to ratio: 1:(100/percentage).

Q3: What are typical slope ranges for different applications?
A: Gentle ramps: 1:20 (5%), Standard ramps: 1:12 (8.33%), Steep ramps: 1:8 (12.5%) - check local regulations.

Q4: Does the calculator work for any units?
A: The calculator uses meters, but the slope ratio is unitless. Ensure rise and run use the same units for accurate results.

Q5: Why is slope important in construction?
A: Proper slope ensures drainage, accessibility, safety, and compliance with building codes and disability access regulations.
