What are ANSI Standard Paper Sizes?

The American National Standards Institute (ANSI) established a standard series of paper sizes beginning with the Letter (8.5" x 11") format and progressing to bigger sizes with the designations A, B, C, D, and E. These ANSI standard sizes were defined in 1992, which is a long time after the ISO standard sizes had already been established. In the 1980s, the United States government formally accepted the letter-size paper set as a national standard in 1921. ANSI Common names for ANSI A paper size include "Letter" and "Ledger" or "Tabloid."

In contrast to the ISO standard sizes, which all have the same aspect ratio of 1:root2, the ANSI standard sizes have two different aspect ratios: 1:1.2941 and 1:1.5455, making it more difficult to increase or reduce between the sizes and resulting in larger margins.

ANSI A-Series

The A-series paper size is the most popular in English-speaking countries; it was adopted in Europe in the 19th century. ISO 216, the international standard for paper, dictated its proportions, which are the square root of two for all sizes. To get the next smaller size in the A series, fold the next largest size in half. An A4 sheet of paper becomes an A5 booklet when folded in half.

ANSI B-Series

The B-series of paper sizes is rarely used but has some specialized uses. The ID-3 passport size is equivalent to a B7. Books are often purchased in B5 bindings. Sheets in the B-series have dimensions determined by taking the geometric mean of the A-series. A B5 sheet, for instance, falls in the middle of the range occupied by an A4 and an A5.

The B-sized pads are nestled in between the A-sized pads to provide a more natural progression from the largest to the smallest size. Access to A and B-sized paper allows for a more nuanced choice based on the user's individual needs and preferred working method.
