<h4>X-Height Analysis</h4>
<p>The x-height of a font significantly impacts readability, especially at smaller sizes. A larger x-height generally means better legibility.</p>

<h2>About This Tool</h2>
<p>This advanced audit goes beyond basic checks to evaluate critical font characteristics that impact readability and WCAG compliance. It analyzes x-height, character distinction, and the potential for creating clear visual hierarchy, helping you choose fonts that are truly accessible for all users.</p>
</section>
<section id="how-to" class="content-section">
<h2>How to Use</h2>
<div>1. Select a Google Font to analyze.<br>2. The tool will display a visual preview of key accessibility indicators, including x-height and commonly ambiguous characters.<br>3. Review the analysis and WCAG guidance to make informed decisions about your font choices.</div>
</section>
<section id="faqs" class="content-section">
<h2>Frequently Asked Questions</h2>
<pre>Q: What makes a font "accessible"?
A: Key factors include unambiguous letterforms (e.g., a slashed zero, a hooked "l"), generous spacing, a large x-height (the height of a lowercase "x"), and a variety of weights to create clear hierarchy.</pre>
<pre>Q: How is x-height measured?
A: X-height is the height of the lowercase 'x' relative to the font's uppercase height or cap height. A higher ratio generally indicates better readability.</pre>
<pre>Q: Does this tool guarantee WCAG compliance?
A: This tool provides guidance on font characteristics related to WCAG. Full compliance depends on overall design, color contrast (which you can check with our Font Color Tester), and implementation.</pre>
