# Window: sizeToContent() method



The **`Window.sizeToContent()`** method sizes the window
according to its content. In order for it to work, the DOM content should be loaded when
this function is called—for example, once the [DOMContentLoaded](https://developer.mozilla.org/en-US/docs/Web/API/Document%2FDOMContentLoaded_event) event has
been thrown.

Since Firefox 20, the minimal size of the window is clamped to prevent the window from
being too small for the user to interact with.

## Syntax

```js-nolint
sizeToContent()

### Parameters

None ([undefined](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/undefined)).
