Set height of View containing WebView based on content - react-native

Question

I want to set my WebView to be the same height as the content I want to display, nothing more.
I have a WebView wrapped in a View:
<View style={height: height}>
<WebView
...
onMessage={event => console.log(event.native.data)} // this returns height of element in px
/>
Inside the WebView, it is simply a div. I'm using postMessage to send to my React Native app, the height of the div on the WebView. How do I convert that number (in px) for styling in React Native?
I've tried using PixelRatio.getPixelSizeForLayoutSize but it was not right. Thanks in advance!

You can use react-native-autoheight-webview, it will set height based on content.
import AutoHeightWebView from 'react-native-autoheight-webview'
import { Dimensions } from 'react-native'
<AutoHeightWebView
style={{ width: Dimensions.get('window').width - 15, marginTop: 35 }}
customStyle={`
* {
font-family: 'Times New Roman';
}
p {
font-size: 16px;
}
`}
onSizeUpdated={size => console.log(size.height)}
source={{ html: `<p style="font-weight: 400;font-style: normal;font-size: 21px;line-height: 1.58;letter-spacing: -.003em;">Tags are great for describing the essence of your story in a single word or phrase, but stories are rarely about a single thing. <span style="background-color: transparent !important;background-image: linear-gradient(to bottom, rgba(146, 249, 190, 1), rgba(146, 249, 190, 1));">If I pen a story about moving across the country to start a new job in a car with my husband, two cats, a dog, and a tarantula, I wouldn’t only tag the piece with “moving”. I’d also use the tags “pets”, “marriage”, “career change”, and “travel tips”.</span></p>` }}
