How to Calculate a 110 Ramp Length

Like most ramps used for launching into the air, the 110 ramp forms a typical right triangle (which has a perfect 90-degree angle in it). These ramps are popular with motocross sports as well as the more venturous and daring all-terrain vehicle (ATV) riders looking to catch some serious air. Learn how to calculate the length of your 110 ramp in order to maximize the level of safety by knowing how much distance you have before it's time to jump.

      Use the tape measure to quantify the height of the top part of the ramp. Place the tape measure on the floor in front of the vertical side of the ramp, then pull the tape up to the highest point of the obstacle. Write down this number.

      Use the tape measure to quantify the length of distance the ramp covers on the ground. Place the tape measure at the lowest point of the ramp, then pull the tape alongside the ramp to measure the horizontal distance of the portion of the ramp that rests on the ground. Write this number down.

      Use the Pythagorean theorem to calculate the length of the triangles longest leg (known as the hypotenuse). Square the first and second measurements you found, then add them together; in other words, say your ramp stood 2 feet tall and covered 4 feet of ground. Square the 2 (which equals 4) and the 4 (which equals 16), then add them together, giving you 20.

      Calculate the square root of the final measurement to find the length of the ramp. In other words, using the number 20 from our previous example, taking the square root of it would mean that our ramp has a length of 4.47 feet.
