Enter the warp cover factor and the warp count into the Calculator. The calculator will evaluate the Ends Per Inch.

## Ends Per Inch Formula

EPI = WCF * SQRT(WC)

Variables:

- EPI is the Ends Per Inch (ends/in)
- WCF is the warp cover factor
- WC is the warp count

To calculate Ends Per Inch, multiply the warp cover factor by the square root of the warp count.

## How to Calculate Ends Per Inch?

The following steps outline how to calculate the Ends Per Inch.

- First, determine the warp cover factor.
- Next, determine the warp count.
- Next, gather the formula from above = EPI = WCF * SQRT(WC).
- Finally, calculate the Ends Per Inch.
- 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.

warp cover factor = 3.4

warp count = 2
