Frequently Asked Questions
What is the difference between ISO 216 and ANSI paper standards?
ISO 216 (used globally by all countries except US, Canada, and parts of Mexico) is based on a geometric 1:√2 aspect ratio where cutting a sheet in half produces the next size. ANSI (used in North America) uses arbitrary aspect ratios based on historical imperial sheet sizes like Letter (8.5x11 in) and Legal (8.5x14 in).
What is a PostScript point?
In digital prepress, 1 point (pt) is defined as exactly 1/72 of an inch (0.3528 mm). This standard is used by PDF, Adobe InDesign, and typography engines worldwide.
