Units

PDFs are measured in points (1/72"), i.e., each point is 1/72 of an inch. That is, the paper size of an US letter is in points 8.5 * 72 = 612 wide and 11 * 72 = 792 high.

The following helper are exported:

• pdf.mm
• pdf.cm

Example:

{ padding: 15 * pdf.mm }

Paper Sizes:

• A4 (default) - 210mm × 297mm (8.27in × 11.7in) = 595.296 x 841.896
• American Letter - 215.9mm × 279.4mm (8.5in × 11in) = 612 x 792
