> I assume it would involved some trigonometry to calculate 1/72 inch? Yes, this is exactly the kind of relative-size calculation @chrissam42 and I made [sizecalc.com](https://sizecalc.com) for. > So, 4/3 px should theoretically already equal 3 arcminutes That would be nice. However, the CSS spec [uses 28 inches](https://www.w3.org/TR/CSS22/syndata.html#img-pixel1) as the base viewing distance for its calculations, explicitly defining 1px as 0.0213 degrees (i.e. ~1.2789 arcminutes). As such, 4/3px only equals ~1.7052 arcminutes. -- GitHub Notification of comment by nicksherman Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/4430#issuecomment-640714381 using your GitHub account
