1. What is a Handicap Ramp Length Calculator?

Definition: This calculator estimates the required length of a handicap ramp based on the vertical rise that needs to be overcome.

Purpose: It helps builders, architects, and property owners determine the proper ramp length to meet ADA accessibility requirements.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( L \) — Length of ramp (feet)
• \( \text{rise} \) — Vertical height to overcome (feet)

Explanation: The formula follows the ADA recommendation of 1:12 slope (1 inch of rise per 1 foot of run). This means for every foot of vertical rise, the ramp should extend 12 feet horizontally.

3. Importance of Proper Ramp Length

Details: Correct ramp length ensures accessibility, safety, and compliance with building codes. Too steep ramps can be dangerous for wheelchair users.

4. Using the Calculator

Tips: Simply enter the vertical rise in feet that the ramp needs to overcome. The calculator will determine the minimum recommended length.

5. Frequently Asked Questions (FAQ)

Q1: Is this calculation ADA compliant?
A: Yes, this follows the ADA's 1:12 slope requirement for wheelchair ramps.

Q2: When would I need a different slope?
A: For existing buildings where space is limited, ADA allows 1:10 or 1:8 slopes under specific conditions, but 1:12 is preferred.

Q3: Does this include landings?
A: No, remember to add platform landings (minimum 5' long) at the top, bottom, and every 30' of horizontal run.

Q4: What about ramp width?
A: ADA requires minimum 36" width between handrails. Our calculator focuses on length only.

Q5: How do I measure the rise?
A: Measure the vertical distance from the lower level to the upper level where the ramp will be installed.
