Paper Sizes — A, B, C, US, Photo & Business Card Dimensions
Paper sizes are standardised dimensions for print and stationery. The international ISO 216 standard defines the A and B series; the C series covers envelopes. North America uses its own sizes (Letter, Legal, Tabloid). Photo and business-card sizes follow photographic and industry conventions. All dimensions on this page are in portrait orientation.
