B1+ Paper Size

B1+ is a paper size that falls between the B1 and B0 sizes. Its dimensions are 707 mm x 1000 mm or 27.8 inches x 39.4 inches. Like all B series paper sizes, B1+ uses an aspect ratio of 1:√2. This means that if you fold a sheet of B1+ paper in half, you get two sheets of B2 paper, and if you fold a sheet of B2 paper in half, you get two sheets of B3 paper, and so on.

B1+ paper is often used for printing posters, banners, and other large-format documents. Its size provides enough space for graphics, text, and other design elements to be clearly displayed. Because it is slightly larger than B1 paper, it offers more room for artwork, images, and text to be included without compromising the overall layout.

The B1+ paper size is also useful for architects and engineers who need to print detailed diagrams, blueprints, and plans. Its large size allows for intricate details to be included, making it easier for builders and contractors to interpret the plans accurately. Additionally, B1+ paper is sometimes used by designers who need to print large-scale designs, such as maps or technical drawings.

Overall, B1+ paper provides a good compromise between the larger B0 size and the smaller B1 size. Its slightly larger dimensions offer more space for design elements without being too cumbersome to handle. This makes it a popular choice for printing large-format documents that need to be both visually appealing and practical.
