Inches, and the metric original
| Dimension | Inches | Fraction | Millimetres |
|---|---|---|---|
| Width | 3.370 in | ≈ 3⅜ in | 85.60 mm |

How it compares to other US card formats
| Card type | Size (inches) |
|---|---|
| Credit / bank card | 3.37 × 2.13 in |
| US business card | 3.5 × 2 in |
| US driver's licence | 3.37 × 2.13 in (same standard) |
| Index card (smallest) | 3 × 5 in |
A credit card and a US business card look interchangeable but are not: the card is slightly narrower and noticeably taller (2.13 in versus 2 in). If you are printing something meant to fit a wallet card slot, build to 3.37 × 2.13 in, not to business-card dimensions — the extra height is what makes it sit correctly.
