1. What is ADA Compliant Ramp Slope?

The ADA (Americans with Disabilities Act) compliant ramp slope ensures accessibility for individuals with disabilities. It specifies the maximum allowable slope for ramps to provide safe and comfortable access.

2. How Does the Calculator Work?

The calculator uses the slope formula:

Where:

• \( Rise \) — Vertical height change (unitless)
• \( Run \) — Horizontal distance (unitless)

Explanation: The slope represents the ratio of vertical rise to horizontal run, indicating the steepness of the ramp.

3. Importance of ADA Compliance

Details: ADA compliant ramp slopes ensure accessibility for wheelchair users and individuals with mobility impairments, promoting safety and equal access to facilities.

4. Using the Calculator

Tips: Enter the rise and run values (both unitless). Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the maximum ADA compliant slope?
A: The maximum slope for ADA compliant ramps is 1:12, which means for every 1 unit of rise, there should be at least 12 units of run.

Q2: Why is ADA compliance important?
A: ADA compliance ensures that buildings and facilities are accessible to all individuals, including those with disabilities, promoting inclusivity and safety.

Q3: When should ramp slope be calculated?
A: Ramp slope should be calculated during the design and construction phases to ensure compliance with ADA standards and local building codes.

Q4: Are there exceptions to the 1:12 slope requirement?
A: In some cases, steeper slopes may be allowed for existing buildings where space constraints exist, but these must meet specific ADA exceptions and requirements.

Q5: How is slope typically expressed?
A: Slope is often expressed as a ratio (e.g., 1:12) or as a percentage, but this calculator provides the unitless slope value.
