# How do iframe sizes affect the Pro LiveTracker layout?
The current Pro version of the football **LiveTracker** provides three layouts: **Single**, **Double**, and **TopDown**. Although each layout has a different shape, all three include the **Scoreboards**, **LiveTracker**, and **Stats** panels.
* **Single** and **Double** are designed for rectangular or square frames, such as computer or TV screens.
* **TopDown** is designed for vertical frames, such as smartphone screens.
The **Scoreboards** and **Navigation bar** have fixed heights based on your configuration. You can disable these components in your product.
The **LiveTracker** and **Stats** panels are responsive and cannot be removed. Their height and width adjust automatically to the iframe size. Make sure that each panel has a minimum height of `175px` and a minimum width of `320px`.
If the iframe does not meet the minimum size required by the selected layout, the widget automatically falls back to the **Single** layout. For example, if you select the **Double** layout, it falls back to **Single** when the widget width is less than `640px` or the **LiveTracker** panel width is less than `320px`.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.thesports.com/help-center/live-experiences/how-do-iframe-sizes-affect-the-pro-livetracker-layout.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
