B8 paper is one of the smallest sizes in the B series. It measures 62 mm by 88 mm, which is about 2.4 inches by 3.5 inches. B8 paper is commonly used for things like business cards or small notes. It’s also sometimes used for printing small photos or graphics.
Like all the sizes in the B series, B8 paper has an aspect ratio of 1:root2. This means that if you cut a B8 sheet of paper in half, you’ll get two B9 sheets, which are the same aspect ratio as the B8. You can continue cutting in half to get even smaller sizes, like B10, B11, and B12.
B8 paper is not as commonly used as some of the larger sizes in the B series, like B4 or B5. However, it’s still an important size for some purposes, especially for printing small cards or notes. If you need to print something small and compact, B8 paper might be the perfect size for your needs.
Overall, B8 paper is a small but important size in the B series. It has a variety of uses and is often used for printing business cards, notes, and small graphics.
