I have used react-native-webview for rendering HTML text. But text is too small in iOS while in android it is perfect.

Here are lines of code : 

import { WebView } from "react-native-webview";


render() {
  <WebView
        originWhitelist={['*']}
        source={{ html: '<p>This is a static HTML source!</p>' }}
  />
}

Using the viewport meta tag to control layout on mobile browsers

<meta name="viewport" content="width=device-width, initial-scale=1">

<WebView
      originWhitelist={['*']}
      source={{ html: '<html><head><meta name="viewport" content="width=device-width, initial-scale=1.0"></head><body><p>This is a static HTML source!</p></body></html>' }}
/>

According my experiences HTML code should have valid DOCTYPE and html strcuture to render in web-view. If your content just "the body part", wrap it with html and body structure with DOCTYPE annotation to render correctly. Like <!DOCTYPE html><html><head><meta name="viewport" content="width=device-width, initial-scale=1.0"></head><body>${yourHtml}</body></html> – Penology
thank you this works and helped :-) also wrapping content body content around headers in the WebView prevents its modification within body :-) – Froh

Additionally to the <meta> you can add <style> tag into the <head> section to scale the font:

<style>
    body { font-size: 120%; word-wrap: break-word; overflow-wrap: break-word; }
</style>

This works pretty fine to me,

    <!DOCTYPE html>
    <html>
      <head>
        <meta name="viewport" content="width=device-width" initial-scale="1.00" maximum-scale="1.0">
      </head>
      <body>
        <p style='text-align:center;'>
           Hello World!
       </p>
      </body>
    </html>

Works in both Android and IOS
