# PrimitiveBoundingBox - ComfyUI Built-in Node Documentation

> The PrimitiveBoundingBox node creates a simple rectangular area defined by its position and size.

The PrimitiveBoundingBox node creates a simple rectangular area defined by its position and size. It takes X and Y coordinates for the top-left corner, along with width and height values, and outputs a bounding box data structure that can be used by other nodes in a workflow.

## Inputs

| Parameter | Description                                                                | Data Type | Required | Range      |
| --------- | -------------------------------------------------------------------------- | --------- | -------- | ---------- |
| `x`       | The X-coordinate for the top-left corner of the bounding box (default: 0). | INT       | Yes      | 0 to 16384 |
| `y`       | The Y-coordinate for the top-left corner of the bounding box (default: 0). | INT       | Yes      | 0 to 16384 |
| `width`   | The width of the bounding box (default: 512).                              | INT       | Yes      | 1 to 16384 |
| `height`  | The height of the bounding box (default: 512).                             | INT       | Yes      | 1 to 16384 |

Note: All maximum values follow ComfyUI's MAX\_RESOLUTION constant, which defines the largest image dimension the node accepts.

## Outputs

| Output Name    | Description                                                                                          | Data Type     |
| -------------- | ---------------------------------------------------------------------------------------------------- | ------------- |
| `bounding_box` | A data structure containing the `x`, `y`, `width`, and `height` properties of the defined rectangle. | BOUNDING\_BOX |
