Enter the line weight (N), the line length (m), and the line sag (m) into the Slackline Tension Calculator. The calculator will evaluate the Slackline Tension.

## Slackline Tension Formula

The following formula is used to calculate the Slackline Tension.

**ST = (LW*L) / (4*S)**

Variables:

- ST is the Slackline Tension (N)
- LW is the line weight (N)
- L is the line length (m)
- S is the line sag (m)

## How to Calculate Slackline Tension?

The following steps outline how to calculate the Slackline Tension.

- First, determine the line weight (N).
- Next, determine the line length (m).
- Next, determine the line sag (m).
- Next, gather the formula from above = ST = (LW*L) / (4*S).
- Finally, calculate the Slackline Tension.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem:**

Use the following variables as an example problem to test your knowledge.

line weight (N) = 45

line length (m) = 30

line sag (m) = 5

ST = (LW*L) / (4*S) =** ** ?
