19.69 × 27.83 inches · 50 × 70.7 cm · aspect ratio 1:1.41
B2 size is 500 × 707 mm. Those are the B2 dimensions a printer works to; the same sheet in centimetres, inches, points and pixels is below.
What B2 is for
B2, 500 × 707 mm, is a point-of-sale and poster size, sitting between A2 and A1. It is large enough to be read across a shop floor and small enough to fit a standard poster frame ordered by the same name.

B2 in pixels
Pixel dimensions depend entirely on the resolution you are working at — there is no single "pixel size" for a sheet of paper. B2 size in pixels has every resolution, with file sizes and canvas setup.
| Resolution | Pixels | Use |
|---|---|---|
| 72 DPI | 1417 × 2004 | Screen preview only — far too coarse to print |
| 150 DPI | 2953 × 4175 | Draft printing, internal documents |
| 300 DPI | 5906 × 8350 | The standard for commercial print |
| 600 DPI | 11811 × 16701 | 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.
How B2 relates to the rest of the series
B2 is B0 halved 2 times. Halving a sheet across its longer side is what generates the next size down, and because the sides are in a 1:√2 ratio the proportions survive every fold — which is the entire reason the series exists.
That makes 4 sheets of B2 exactly one sheet of B0, with nothing left over. The area works out at 0.25 m², since B0 is defined as one square metre.
Scaling to the next size up or down is a factor of √2 ≈ 1.414 on each edge, so enlarging B2 to the next size is 141% on a photocopier and reducing it is 71%. Those two numbers are on the preset buttons of most copiers for exactly this reason, and they are the same for every size in the series.
