<p>If you want to use <code>font-size</code> speicifically in <code>points (e.g. 10pt)</code>, you can convert the <code>font-size</code> returned in <code>px</code> using <code>fontSize * 72 / 96</code> to <code>pt</code> and then compare it with <code>10</code> or whichever font-size you have.</p>

<p>Used <code>Math.round</code> for handling precision in conversion.</p>
