Why is paragraph text shrinking in Chrome for Mobile?

Can you check if your Chrome font size is at 100% in settings on your phone? Chrome for Android has an option to render font at a different value. You can find this option in: Menu -> Settings -> Accessibility. I did a mistake like this some weeks ago and I want to be sure that is not the case here. Sorry if I'm out of the line here.

I also found that for some unknown reason sometimes Chrome for Android set this font setting wrong at installation time. I could not replicate this behavior but I got one phone, of a relative, with this so it might be possible that you are not aware of the fact that this setting is not set at 100%.

For cross compatibility for my web pages I tend to use the following:

<meta name="viewport" content="width=device-width, initial-scale=1.0">

This seems to work with no additional styling with CSS needed for the mobile platforms. Not sure if it what you want though.
