Select the paper size in the “Size” selection and the unit in the “Unit” selection – the dimensions are displayed in the “Dimensions” field. B Plus, or Super B as it is sometimes called, has dimensions of 13″ x 19″ (330mm x 483mm). This size is ANSI-B size with a margin of 1 inch for a complete cut of the print. It is sometimes referred to as A3+ or Super A3 in countries that use ISO 216 paper sizes. European manufacturers sometimes indicate this size as 330mm x 482mm. There is also the U.S. national standard ANSI/ASME Y14.1 Decimal inch drawing sheet size and format for technical drawing paper and other non-systematic formats for various applications. The page size of the ledger is 11″ x 17″ (279mm x 432mm) as shown in the map below. North America also has a special set of paper sizes defined for architectural purposes, usually these have 4:3 or 3:2 aspect ratios.
These aspect ratios are very similar to those used for computer monitors. ANSI (American National Standards Institute) has defined a regular series of paper sizes based on the letter size (8.5″ x 11″), becoming size A and larger formats B, C, D&E. Surprisingly, in 1992, these ANSI standard sizes were defined well after the ISO standard formats. Letter size paper was originally defined as a national standard in 1921 and officially adopted by the U.S. government in the 1980s. The ANSI A format is commonly referred to as a letter and ANSI B is a ledger or tabloid. ISO standardized paper sizes are not widely used in the United States and Canada. Instead, paper sizes such as “Letter” (8.5 x 11 inches), “Legal” (8.5 x 14 inches), “Executive” (7 x 10 inches) and “Ledger / Tabloid” (11 x 17 inches) are widely available. The formats “Letter”, “Legal”, “Tabloid” and other formats (but not these names) are defined in the US national standard ANSI X3.151. Some websites also list Arch E2 at 26.0 x 38.0 inches (660 x 965 mm) and Arch E3 at 27.0 x 39.0 inches (686 x 991 mm), but we can`t find any references to these sizes on ANSI`s website, which lists A, B, C, D, E, and E1. In addition, these two sizes do not have simple aspect ratios, which are a common feature of the paper sizes of the Arch series. The Arch E3 format is available from some paper vendors, where it is only called 27 x 39 and Arch E2 doesn`t seem to be available at all.
The following page covers North American paper weights in detail, as it helps to know how weight, size, and type of paper affect your choice of paper. The difference between US and international legal letter and paper sizes is discussed here, but it is important to say that the letter is effectively the equivalent of A4 in the US. Paper sizes in North America do not have a uniform aspect ratio like the ISO standard. They have their own system that they follow. This means that scaling paper sizes is more difficult. The American stationery size is the most popular format used in the United States. It is also commonly used in Chile and the Philippines. The architectural series (ARCH) is used by architects in North America, and they prefer this series to ANSI because aspect ratios are ratios of smaller integers (4:3 and 3:2). ARCH series paper sizes are defined in ANSI/ASME Y14.1. ARCH sizes are often used by architects for their large-scale designs. The American National Standards Institute (ANSI) adopted ANSI/ASME Y14.1, which in 1996 defined a series of paper sizes based on the standard 8.5-inch × 11-inch (216 mm × 279 mm) format, called “ANSI A”.
This series is quite similar to the ISO standard because if you cut one sheet in half, you get two sheets of the immediately smaller size. The ledger/tabloid is known as “ANSI B”. The most common and widely used size is ANSI A, also known as a “letter”. Among major Americans, letters, legal, and ledger/tabloid are the most commonly used in office environments. The half-letter is often used to write personal letters, notepads and diaries. Government Letter is still widely used, but Government Legal (known as Long Bond in the Philippines) is much rarer these days. The dimensions of ledger paper are officially only found in the United States and Canada, as these are the only two countries that have not officially adopted ISO standard paper sizes. The most commonly used sizes are known as letter, legal, general ledger and tabloid. (The size of the letter is also called “American Quarto” outside the United States.) There are many other sizes and shapes of pages, but these are the most commonly used. North America, including the United States, Canada and parts of Mexico, is the only first-world territory that does not use standard ISO 216 paper sizes, but rather Letter, Legal, Executive and Ledger/Tabloid paper sizes, as well as those formalized in ASME Y14.1 – Drawing sheet size and size. ANSI also includes ISO 216 with ASME Y14.1M – Metric Drawing Sheet Size and Format US envelope sizes are also not ISO 216 and are listed on this page. The following table shows the sizes in millimeters and inches of commonly used U.S.
paper sizes.
