I would like to know why I am getting a larger font size on Safari on iPad compared to any browser on Mac, even Safari. And how to solve it!
This is a WordPress forum and the screenshots attached show 1 post. Take a look at the date: “April 18, 2012”. It is larger in the 2nd screenshot (iPad) than the 1st. Why is that? There is no CSS is play here – it is all commented out.
Safari Mac:

Safari iPad:

FYI Im not using any special iPad meta tags & JS is disabled as well.
The HTML for this part in question is as follows:
<div class="post-7 post type-post status-publish format-standard hentry category-two tag-tag1 tag-tag2 tag-tag3" id="post-7">
<h2 class="entry-title"><a rel="bookmark" title="Permalink to Pellentesque elementum nulla mattis elit ullamcorper nec viverra felis mattis" href="http://foscavir.local.etalented.co.uk/blogs/pellentesque-elementum-nulla-mattis-elit-ullamcorper-nec-viverra-felis-mattis/">Pellentesque elementum nulla mattis elit ullamcorper nec viverra felis mattis</a></h2>
<div class="entry-meta">
April 18, 2012 </div><!-- .entry-meta -->
</div>
First thing you could try is: -webkit-text-size-adjust
Edit: set it to 100% like proposed in comments.
