### Answer Based on the available documentation, the Retell chat widget does not have a built-in attribute to change the widget size or height. [(1) ]() The customizable attributes available are: -

data-title

– Custom chat window title -

data-logo-url

– URL of your logo image -

data-color

– Hex color code for widget theme -

data-bot-name

– Bot name for popup messages -

data-popup-message

– Popup message before users open chat -

data-auto-open

– Auto-open chat widget on page load There is no

data-height

,

data-width

, or size-related attribute documented for the widget. If you need to adjust the widget's dimensions, you may need to apply custom CSS targeting the widget's iframe or container elements on your website, though this would be outside of Retell's official configuration options. Check out these potentially useful sources: - [Retell Website Widget]() - [Retell Chat Widget | How to Customize your Retell chatbot]() Would you like me to provide a general approach for styling embedded widgets with CSS?
