title: measurements
---
The `measurements` key in the pattern configuration file allows you to configure
the measurments that are required to draft the pattern.
## Structure
An array of strings where the strings are the names of the measurements
required to draft this pattern.
## Example
```js
measurements: [
"bicepsCircumference",
"centerBackNeckToWaist"
]
```
###### Don't just make up names
See [freesewing models](https://freesewing.dev/reference/packages/models)
for a list of measurement names already used in freesewing patterns.
It is a [best practice](/guides/best-practices/reuse-measurements/) to stick to these names.
This configuration is for **required measurements** only.
There is a also a way to configure [optional
measurements](/reference/api/config/optionalmeasurements)
