# Default Value Parameters

## DEFAULT_USER_PREFERENCES

!!! tip "Dynamic Configuration Parameter"

This is a dictionary defining the default preferences to be set for newly-created user accounts. For example, to set the default page size for all users to 100, define the following:

```python
DEFAULT_USER_PREFERENCES = {
    "pagination": {
        "per_page": 100
    }
}
```

For a complete list of available preferences, log into NetBox and navigate to `/user/preferences/`. A period in a preference name indicates a level of nesting in the JSON data. The example above maps to `pagination.per_page`.
