title: utils.getTransformedBounds()
---
The `utils.getTransformedBounds()` function re-calculates the bounding box of an object (a stack or a part) after applying the passed-in transform(s).
The object passed in should have its `topLeft` and `bottomRight` properties set.
It will return on object that with (only) the updated `topLeft` and `bottomRight` properties set.
## Signature
```js
Object utils.getTransformedBounds(
Object stack,
Array transforms
)
```
:::note
This is a low-level function to facilitate intervening in the pattern layout late in the draft process.
It is unlikely you will want to use this.
