English Wikipedia (and most likely any other Wikimedia site running MediaWiki) has pages that are literally hundreds-times bigger than their actual content. I did a testing consisting of saving a blank Wikipedia article page and it ended up being 211,207 bytes of stuff to download (HTML, JavaScript, images etc.) for exact 1,249 bytes of text (menus, header, footer etc.). This resolves into a 169:1 ratio for article size vs. article actual content. Pretty big number, isn’t it?
