B2

The B2 paper size is part of the ISO B series used for large-format printing and technical drawings. With dimensions of 500 x 707 mm, B2 is the third largest size in the B system. It maintains the distinctive height-to-width ratio of 1:√2 (approximately 1:1.4142) that allows efficient scaling between sizes.

With a surface area of 0.35 square meters, B2 provides a sizeable printing space while being more manageable than B0 and B1. Its substantial dimensions make B2 a versatile choice for wide posters, banners, infographics, architectural drawings, and more. The origins of B2 date back to the German DIN 476 standard from 1922 before being adopted as an ISO standard in 1975. Today, B2 is popular for visually communicating detailed plans and data across architecture, engineering, manufacturing, and graphic design. Its balance of size and portability gives B2 broad utility across large-format documents.
