Enter the ramp height (ft) and the ramp angle (degrees) into the Ramp Length Calculator. The calculator will evaluate the Ramp Length.

## Ramp Length Formula

The following two example problems outline the steps and information needed to calculate the Ramp Length.

**RL = H / SIN(a)**

- Where RL is the Ramp Length (ft)
- H is the ramp height (ft)
- a is the ramp angle (degrees)

## How to Calculate Ramp Length?

The following example problems outline how to calculate Ramp Length.

Example Problem #1:

- First, determine the ramp height (ft).
- The ramp height (ft) is given as: 4.

- Next, determine the ramp angle (degrees).
- The ramp angle (degrees) is provided as: 30.

- Finally, calculate the Ramp Length using the equation above:

RL = H / SIN(a)

The values provided above are inserted into the equation below and computed.

RL = 4 / SIN(30deg) = 8.00 (ft)

Example Problem #2:** **

For this problem, the variables required are provided below:

ramp height (ft) = 6

ramp angle (degrees) = 45

Test your knowledge using the equation and check your answer with the calculator..

RL = H / SIN(a)** = ?**
