/test-page/Paper Size Standards & Dimensions
All 22 international and regional standards encompassing 257 distinct standardized sheet sizes.
The A series traces its standardised dimensions to DIN 476, published in Germany in 1922. Georg Christoph Lichtenberg had described the underlying square-root-of-two aspect-ratio principle in 1786. ISO 216 brought the A and B trimmed-paper formats into an international standard in 1975; numbered A sizes retain approximately the same proportions as each sheet is halved.
The B series paper sizes are defined by the ISO 216 standard. B sizes are geometric means between consecutive A sizes, providing intermediate sizes for when A sizes are not suitable.
US paper sizes are used primarily in the United States and Canada. The most common sizes are Letter (8.5 × 11 inches) and Legal (8.5 × 14 inches).
The C series envelope sizes are defined in ISO 269. C envelopes are designed to hold A series paper: a C4 envelope holds an A4 sheet, a C5 holds A5 or a folded A4, etc.
Photography paper sizes are used for printing photographs. These sizes are based on common aspect ratios and print dimensions used in professional and consumer photography.
US envelope sizes are commonly used in the United States for business and personal correspondence. The most common is the #10 envelope used for standard business letters.
International envelope sizes follow the ISO 269 standard. The DL envelope is the most commonly used internationally, designed to hold an A4 sheet folded in thirds.
Book paper sizes are standardized formats used in the publishing industry. Common formats include A Format (mass market paperback), B Format (trade paperback), and various Octavo sizes.
Newspaper paper sizes vary by country and publication. The most common formats are Broadsheet, Tabloid (Compact), and Berliner (Midi).
Business card sizes vary by country and region. The most common international standard is ISO 7810 ID-1, which is the same size as a credit card.
Colombian paper sizes are used in Colombia and some other Latin American countries. The Carta size is equivalent to US Letter.
Chinese paper sizes follow the GB/T 148 standard. The D series is used primarily in China for printing and writing.
Traditional French paper sizes have colorful names derived from watermarks, coat of arms, and other historical symbols used by French papermakers.
German DIN paper sizes are a set of supplementary sizes defined in the DIN 476 standard. The D series provides intermediate sizes between the A and B series.
Japanese paper sizes include the JIS B series (JB), which differs from the ISO B series. Japan also uses unique sizes like Kiku and Shiroku ban for specific publishing applications.
Transitional paper sizes bridge the gap between the ISO A series and US paper sizes. The PA series was designed as a compromise for international documents.
Swedish paper sizes follow the SIS (Swedish Standards Institute) system with D, E, F, and G series providing a wider range of sizes than the ISO standard.
Imperial paper sizes are traditional British paper sizes that predate the ISO standard. Many of these sizes have historical names like Crown, Demy, Royal, and Elephant.
Billboard sizes are large-format sheet sizes used for outdoor advertising and posters. They are defined by the number of sheets required to create the billboard.
Raw paper sizes (SRA and RA) are slightly larger than their A-series counterparts, providing extra space for bleed, grip, and trim during commercial printing.
Canadian paper sizes (P series) were defined by the Canadian Standards Association. They are similar to the ISO A series but with slightly different dimensions.
Traditional British writing paper sizes were historically used in the United Kingdom before the adoption of ISO 216.
