Enter the span between oarlocks (in) into the Oar Length Calculator. The calculator will evaluate the Oar Length.

## Oar Length Formula

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

**OL = (S/2+2) * 25 / 7 **

- Where OL is the Oar Length (inches)
- S is the span between oarlocks (in)

## How to Calculate Oar Length?

The following example problems outline how to calculate Oar Length.

Example Problem #1:

- First, determine the span between oarlocks (in).
- The span between oarlocks (in) is given as: 15.

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

OL = (S/2+2) * 25 / 7

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

OL = (15/2+2) * 25 / 7 = 33.92 (inches)

Example Problem #2:** **

For this problem, the variables required are provided below:

span between oarlocks (in) = 20

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

OL = (S/2+2) * 25 / 7 ** = ?**
