Business Card (US) size is 88.9 × 50.8 mm. Those are the Business Card (US) dimensions a printer works to; the same sheet in centimetres, inches, points and pixels is below.
What Business Card (US) is for
The North American business card is 3.5 × 2 inches, sized to fit a wallet card slot. Standard practice is 3 mm of bleed and a 5 mm safe margin, which matters more here than on larger work: the card is small enough that a 1 mm trim shift is visible, and text set close to the edge on one card in a stack will look off-centre on the next.

Business Card (US) in pixels
Pixel dimensions depend entirely on the resolution you are working at — there is no single "pixel size" for a sheet of paper. Business Card (US) size in pixels has every resolution, with file sizes and canvas setup.
| Resolution | Pixels | Use |
|---|---|---|
| 72 DPI | 252 × 144 | Screen preview only — far too coarse to print |
| 150 DPI | 525 × 300 | Draft printing, internal documents |
| 300 DPI | 1050 × 600 | The standard for commercial print |
| 600 DPI | 2100 × 1200 | 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 Business Card (US) relates to the rest of the series
At 88.9 × 50.8 mm (3.5 × 2 inches) the aspect ratio is 1:1.750. This size is not part of a halving series, so there is no fixed scaling factor to the next size up or down — each one is defined on its own terms.
The closest ISO sheet by area is A8 at 52 × 74 mm — this size is 17% larger. The proportions differ, though: A8 is 1:1.414 like every A size, and this one is 1:1.750, so content laid out for one does not fill the other without cropping or white space.
