How to calculate the text that can fit in a WebView without scrolling

I want to write an viewer that can display text justified, and it should display the amount of text that it can show on one screen without scrolling. Let say if I use WebView for justifying text, how to calculate the size of the text to be set in the view, so that the view can display it properly with that font without scrolling.

2. Send it to your webview via a JS call, like this
3. The change the size in your HTML/JS.
