B5sized
B5sized refers to a paper size that conforms to the ISO 216 standard. This standard, widely adopted internationally, defines a set of paper dimensions designed to be proportionally related across different sizes. The B series of paper sizes, including B5, is based on a geometric progression where the aspect ratio of each sheet is approximately 1:sqrt(2). This means that if you cut a B5 sheet in half parallel to its shorter side, you get two identical sheets of B6 size.
B5 paper has a specific set of dimensions. In millimeters, it measures 176 x 250 mm. In
