Explore the sizing options for your posters, flyers, documents and more!
B series papers are used as another option when the A series is not suitable. Similar to the A series papers, its dimensions are defined by the ISO 216 International Standard for paper sizes. Using B series is a good idea when the A series is too big or small for the document you’re working on.
The B series sizes are between the paper sizes of each of the series A. For example, B5 measures between A4 to A5.
With the same concept as the A range, a sheet of paper in the B range will result in the next smaller size if folded in half. B3 is half of B2, B2 is half of B1, and so forth. Like the A series, the aspect ratio of the B series is 1: 2.
Although less commonly used in office environments, the B series is important for a variety of special usage. Majority of posters use B series papers and B5 is a standard choice for books. This includes other uses such as envelopes and passports.
