# Length Node
|
|
|
|
## Description
|
|
|
|
Returns the length of input **In**. This is also known as magnitude. A vector's length is calculated with [Pythagorean Theorum](https://en.wikipedia.org/wiki/Pythagorean_theorem).
|
|
|
|
The length of a **Vector 2** can be calculated as:
|
|
|
|
|
|
|
|
Where *x* and *y* are the components of the input vector. Length can be calculated for other dimension vectors by adding or removing components.
|
|
|
|
|
|
|
|
And so on.
