<p dir="auto">One small thing is that I did consider using the diagonal size rather than width+length but my brief tests suggested it caused more variation as the shape of the box changed from square to elongated.</p>
</blockquote>
<p dir="auto">This goes a bit beyond this issue - but mathematically what you currently do (width+length) is the <em>L1 norm</em>.  The diagonal size would be the <em>L2 norm</em>.  At the other end of the scale (see <a href="https://en.wikipedia.org/wiki/Lp_space" rel="nofollow">https://en.wikipedia.org/wiki/Lp_space</a>) you have the L^inf norm, which would be <code class="notranslate">max(width, length)</code>.</p>
<p dir="auto">I don't think which of these you choose ultimately matters since:</p>
<ul dir="auto">
<li>you do this in a highly distorted equirectangular projection anyway.</li>
<li>the bounding box is a highly suboptimal measure for spatial extent of the impact an edit has on the map, even if it was in a low distortion projection.</li>
