PDF page sizes, with real dimensions and margins

A document on screen is a scroll. A document on paper is a fixed rectangle, usually with a machine behind it that expects that exact rectangle. Each page below has the dimensions in millimetres, inches, points and pixels, the margin the printer actually needs, and the CSS that produces the page box.

Six of these are named formats the render API accepts directly. The rest are set in the document itself, which is a supported path rather than a workaround: see setting the page size in CSS, or the full paged media reference. For a complete document already set to one of these sizes, see the document templates. For the label sizes in particular, the thing most likely to go on them is a code, and barcodes that still scan on paper covers the quiet zones those need.
