Car Ramp Slope Ratio Calculator

FAQs

What is the ratio of ramp slope for car? The ratio of ramp slope for a car is often represented as a fraction like 1:12, where the first number is the rise (vertical height) and the second number is the run (horizontal length). For example, a 1:12 slope means that for every 1 unit of vertical rise, there should be 12 units of horizontal run.

How do you calculate ramp ratio on a car? To calculate the ramp ratio, divide the rise of the ramp (vertical height) by the run of the ramp (horizontal length). For example, if the ramp has a rise of 12 inches and a run of 144 inches (12 feet), the ramp ratio would be 1:12.

How long should a ramp be for 24 inches? If you’re using a 1:12 slope, the ramp should be approximately 24 feet long. (24 inches rise divided by 12 equals 2 feet, so you’d need 24 feet of horizontal run.)

At what slope will a car bottom out? The point at which a car will bottom out depends on several factors including the car’s ground clearance, suspension, and the shape of the undercarriage. Generally, very low cars might start experiencing issues on slopes around 10-12% (around 6-7 degrees) or steeper.

What is the best slope for a car? For most cars, a slope of 10-12% (about 6-7 degrees) is considered a reasonable maximum for regular driveways or ramps. However, for accessible ramps, a 5% slope (1:20 ratio) is often recommended for better mobility.
