What JIS B5 is for
JIS B5 is 182 × 257 mm. The most-used JIS B size and the standard notebook and textbook page in Japan — every Japanese stationery brand builds around it. ISO B5 is 176 × 250 mm, six millimetres narrower and seven shorter, which is why an imported B5 binder does not quite fit a domestic B5 pad.

JIS B5 in pixels
Pixel dimensions depend entirely on the resolution you are working at — there is no single "pixel size" for a sheet of paper. Every resolution, with file sizes and canvas setup →
| Resolution | Pixels | Use |
|---|---|---|
| 72 DPI | 516 × 729 | Screen preview only — far too coarse to print |
| 150 DPI | 1075 × 1518 | Draft printing, internal documents |
| 300 DPI | 2150 × 3035 | The standard for commercial print |
| 600 DPI | 4299 × 6071 | Fine detail, line art, archival scanning |
Setting up a print document? Use 300 DPI and add 3 mm of bleed on every edge unless your printer specifies otherwise.
