B5 in the Japanese JIS B series is 182 × 257 mm (7.17 × 10.12 in), half of B4. At 300 DPI it's 2150 × 3035 pixels. It's the B5 size used in Japan for notebooks, magazines and school worksheets.

Design Tips
- →For print, design at 300 DPI (2150 × 3035 px) in CMYK with 3 mm bleed on every edge, which makes the working canvas 188 × 263 mm.
- →B5 shares the 1:√2 ratio of the A series, so a layout built for an A size scales to B5 without cropping — only the type sizes need checking.
- →Japanese print shops and copiers use JIS B, while most of Europe uses ISO B. Name the standard in your print order: JIS B5 is 182 × 257 mm, ISO B5 is 176 × 250 mm.
- →Keep text and logos at least 5 mm inside the trim so a slightly off-centre cut leaves them intact.
