Ramp Length Formula:
From: | To: |
Definition: This calculator estimates the length of ramp needed for a car based on the height to overcome and the desired slope.
Purpose: It helps determine proper ramp dimensions for vehicle access, garage ramps, or wheelchair accessibility.
The calculator uses the formula:
Where:
Explanation: The height is divided by the slope ratio to determine the required ramp length for safe vehicle access.
Details: Correct ramp length ensures vehicle safety, prevents scraping, and meets accessibility standards.
Tips: Enter the height in feet and desired slope (default 0.125 or 1:8 ratio). Typical slopes range from 0.1 (gentle) to 0.15 (steep).
Q1: What's the recommended slope for car ramps?
A: For most vehicles, a slope between 0.1 (1:10) and 0.125 (1:8) is recommended.
Q2: Can I use this for wheelchair ramps?
A: Yes, but wheelchair ramps typically require gentler slopes (0.083 or 1:12 ratio).
Q3: How does vehicle type affect ramp slope?
A: Low-clearance vehicles need gentler slopes (0.1 or less), while trucks can handle steeper slopes (up to 0.15).
Q4: What if my calculated ramp is too long?
A: Consider switchback designs or increasing the slope slightly if space is limited.
Q5: Does this account for ramp material thickness?
A: No, add extra length if using thick ramp materials that reduce the effective slope.
