Why 16 px equals 12 pt
Two fixed definitions drive every conversion on this page. A typographic point is 1/72 of an inch. A CSS reference pixel is 1/96 of an inch. That makes 1 px exactly 0.75 pt, and 16 px exactly 12 pt — which is why 16 px became the default body size on the web: it matches the 12 pt that print had already settled on.
A pica is 12 points, so 1 pica = 16 px. InDesign, Quark and most print workflows measure column widths and gutters in picas; CSS has no pica unit, so those measurements have to be converted before they reach a stylesheet. On this page, 1 Q = 0.0098425197 in.
The CSS pixel is a reference unit, not a hardware pixel. On a 2× or 3× display, one CSS px still occupies 1/96 inch of visual space — the device simply renders it with more physical pixels. Converting CSS px to physical pixels requires the device pixel ratio, which is a separate calculation from anything on this page.
