What size is used where?
| Format | Dimensions | Inches | Where it is common |
|---|---|---|---|
| US and Canada | 3.5 x 2 in | 3.5 x 2 | United States, Canada |
| European | 85 x 55 mm | 3.35 x 2.17 | Much of Europe |
| ID-1 card format | 85.60 x 53.98 mm | 3.37 x 2.13 | Card format used worldwide |
| Japanese | 91 x 55 mm | 3.58 x 2.17 | Japan |
| ISO A8 | 52 x 74 mm | 2.05 x 2.91 | Occasionally, portrait format |
The US card is wider and shorter than the European one. A European card is about 4 mm narrower and 4 mm taller, which sounds trivial until a US card will not sit flat in a European wallet insert, or a European card rattles in a US cardholder.
Japan's card is the widest of the common formats, and the culture around exchanging cards there is the most formal, which makes fit and condition matter more rather than less.
Does the difference actually cause problems?
Sometimes, in ways that are easy to miss.
- Cardholders, wallet inserts and business card files are cut for one format.
- Card scanners and sheet protectors are sized to a region's standard.
- A taller card can be trimmed by a holder designed for a shorter one.
- A wider card protrudes from a slot and gets dog eared.
- Mixed formats in a stack never sit square, which looks careless.
None of these will lose you a deal on their own. They add up to a card that gets moved to a drawer instead of kept in a wallet, which is exactly the outcome a card exists to prevent.
Which size should you print?
Print the size of the market where the card will be handed over most often. For a business based in the United States that occasionally travels, the US 3.5 x 2 inch card is the right default. For a business whose customers are mainly in Europe or Japan, print that market's size, even if you are based elsewhere.
If you genuinely operate in two regions, the practical answer is two runs rather than a compromise size. A compromise size fits nothing properly, and card printing is cheap enough that a small second run is easier than explaining an odd shape.
If you must choose one card for mixed use, the ID-1 card format at 85.60 x 53.98 mm is the most widely accommodated footprint, because it matches bank card dimensions and therefore fits an enormous number of existing wallets and holders.
How do you design one layout for two sizes?
The two common formats differ by a few millimeters in each direction, so a layout that survives both has to avoid relying on exact positions.
Keep the design centered rather than anchored to one edge. Leave generous margins, at least 4 or 5 mm, so a few millimeters of difference does not crowd anything. Avoid full bleed elements that have to align with a specific edge, and avoid thin border rules, which look obviously wrong at a different aspect ratio. Set the type once and confirm it still reads comfortably in the narrower format.
Then build two files from the correct template for each product, rather than scaling one file. Scaling changes the type size, which is exactly what you were trying to keep consistent.
What about the back of the card abroad?
This is the more useful question. For markets where you do not share a first language, the back is where a second language version belongs.
The existing guide to bilingual business cards covers how to split the two languages so neither looks like the afterthought. Two points specific to travel. First, keep your country code on the phone number, because a number without one is unusable abroad. Second, write the address in the order the destination country expects, or include the country name in English as well as the local form.
What about card etiquette?
Size is the smaller half of the story. In several markets, including Japan, the exchange itself is formal: cards are offered and received with both hands, read before being put away, and never written on in front of the giver.
That has a practical consequence for printing. A card that will be read in the hand for several seconds should be legible, uncluttered and in good condition, which argues for a sturdier stock and a case rather than a pocket. The existing guide to business card etiquette covers the exchange in more detail.
What is the international card checklist?
- Print the size of the market where cards are handed over most often.
- Use two runs rather than one compromise size for two regions.
- Consider the ID-1 card footprint if one card must serve everywhere.
- Keep layouts centered with generous margins so they survive a format change.
- Build each file from the correct template instead of scaling.
- Put the country code on the phone number and the country on the address.
- Carry cards in a case so they arrive flat and clean.
Frequently asked questions
What is the standard business card size outside the US?
There is no single global standard. Much of Europe uses 85 x 55 mm, Japan uses 91 x 55 mm, and many markets sit close to the ID-1 card format of 85.60 x 53.98 mm, the same size as a bank card. The US and Canadian standard of 3.5 x 2 inches is wider and shorter than the European format.
Will a US business card fit a European wallet?
It usually goes in, but not neatly. A US card is about 4 mm wider and 4 mm shorter than an 85 x 55 mm European card, so it can protrude from a slot cut for the European size or sit loosely in a holder. The result is a card that ends up in a drawer rather than a wallet.
Should I print two sizes if I work in two countries?
Usually yes. Card printing is inexpensive enough that two short runs are easier than a compromise size that fits nothing properly. If you truly need one card everywhere, the ID-1 bank card footprint at 85.60 x 53.98 mm is the most widely accommodated, because holders and wallets are built around it.
Can I just scale my card design to a different size?
Scaling changes the type size along with everything else, which is the one thing you want to keep constant. Build each file from the correct template for that product and size, keep the layout centered with margins of at least 4 or 5 mm, and avoid thin borders that reveal the change in proportion.
