paper sizes
Notes
In the United States the most common sizes are letter (8½ × 11 inches) and legal (8½ × 14 inches); manufacturers specify other sizes in inches. British standards include foolscap (13½ × 17 inches), post (15¼ × 19 inches), Demy (17½ × 22½ inches), up to Double Imperial (30 × 44 inches). The German DIN A standard includes sizes ranging from A10 (26 × 37 mm) to 4A0 (1682 × 2378 mm), with A4 (210 × 297 mm) being the closest to letter size. The B sizes are intended for posters, and C sizes for envelopes. The German A and B sizes have been adopted as ISO standards and are now widely used throughout Europe.
