A CSS pixel is not a length, it is an angle: one ninety-sixth of an inch held at arm's length, 0.0213 degrees. A 20/20 letter is five arcminutes, which is 8.73 mm on a chart at six metres and 3.9 reference pixels on a screen. Work out what a pixel really subtends on the screens people own, held where people hold them, and the phone — the one this wall spent a day worrying about — turns out to be the most generous of them all.
