Change font and size

Hello, I would like some feedback on which plugins that able to change font and size in page and post. As of now, it doesn’t included that feature in page and post. I wonder if there any specific plugin that will add that feature? I did browse in plugin, but most of them are for title or some specific area to change size. I prefer a setting added into page/post’s tabs that already included with bold, image, link, etc.

Thanks.
