# Business card size

**Business card: 85 × 55 mm**

Varies by country: 85 × 55 mm in Europe, 89 × 51 mm in the US.

There is no international standard, and the regional sizes differ enough to matter. Europe generally uses 85 × 55 mm, the US and Canada 3.5 × 2 inches (88.9 × 50.8 mm), Japan 91 × 55 mm, and Australia 90 × 55 mm. A card designed for one market sits awkwardly in a wallet or cardholder made for another, which is the practical consequence.
