Business Card Size Guide: Standard Dimensions in the US, UK, Europe, and Asia
Pick the local standard size first, then design to that canvas. This prevents storage and printing problems, and ensures legibility and predictable layout when you hand out cards across borders.
Choosing the right business card size is more than a printing detail. The size you pick affects how the card fits wallets, where it sits in filing systems, how your layout breathes, and how other professionals perceive your brand. This guide compares the common standards across the US, UK, continental Europe, and several Asian markets, explains print-prep rules you must follow, and offers simple decision rules so you pick the right size for your audience and workflow.
Why size matters: beyond aesthetics
Size affects three practical things: physical compatibility, layout constraints, and cultural expectations. A card that is too large may not fit standard wallet slots or business card holders. A card that is too small leaves little room for legible type or necessary elements such as a logo and QR code. In some countries the expected proportions and orientation vary, and using a nonstandard format can look modern or simply awkward depending on the context.
Common standards by region
Below are the most common dimensions you will encounter. All final artwork should include bleed and safe margins; this table shows the trimmed size.
| Region | Typical size (inches) | Typical size (mm) | Notes |
|---|---|---|---|
| United States | 3.5 x 2.0 | 89 x 51 | Most printers use landscape; this is the standard for wallets and Rolodexes. |
| United Kingdom | 3.346 x 2.165 | 85 x 55 | Same as many European cards, slightly taller than US cards. |
| Continental Europe | 3.346 x 2.165 | 85 x 55 | Common across EU countries; convenient for wallets that accept credit card size. |
| Japan | 3.58 x 2.17 | 91 x 55 | Slightly wider variant; Japanese cards are often printed and exchanged with formality. |
| South Korea | 3.346 x 2.165 | 85 x 55 | Matches the Europe/UK dimensions in many cases. |
| China and other Asian markets | Varies, common: 3.346 x 2.165 or 3.54 x 1.97 | 85 x 55 or 90 x 50 | Vertical designs and different aspect ratios are more common in some sectors. |
Interpretation and what each dimension means for design
US card dimensions (3.5 x 2 inches) give a wide, compact layout that suits horizontal logos and a single-line address. The UK standard size and most European card dimensions (85 x 55 mm) are slightly taller, which gives more vertical space for stacked text or dual-language layouts.
Asian business card size practices vary more by country and industry. Japan and some Chinese manufacturers favor sizes close to the credit card footprint, while others prefer vertical cards or slightly different aspect ratios. If you plan to hand cards across borders, choose a size that fits common wallets and card holders in the destination country.
Print preparation: the rules you must follow
- Set bleed: Add 3 mm bleed on all sides for European/Asian printers, or 0.125 inch (3.175 mm) for many US printers. Keep background colors and images extended to the bleed edge.
- Define safe area: Keep critical text and logos at least 3 mm or 0.125 inch inside the trim line so nothing can be cut off.
- Color: Work in CMYK for print, and ask the printer for color profiles if you need exact matches.
- Resolution: Export at 300 DPI at final size. Avoid scaling up raster images in the layout.
- Corner radius: If you plan rounded corners, include the final radius in the dieline so printers know where to cut.
- Export format: PDF/X-1a or a high-quality PDF with fonts embedded is the safest choice for commercial printers.
Choosing between standard and custom sizes
Standard sizes exist for a reason: they fit common holders, are cheaper to print, and ensure consistent cropping. Custom sizes can help you stand out, but they add cost and may cause practical friction. Use this decision rule:
- If you hand out many cards at events or need them to fit wallets and filing systems, choose the regional standard.
- If the card is a brand statement for a high-touch industry, consider a custom size, but test a physical prototype first.
- If you expect recipients to scan or photograph the card, keep essential information and QR codes within the central safe area so scanning apps reliably capture them.
Orientation, corner radius, and special finishes
Orientation affects reading flow. Landscape is standard in the US and Europe. Portrait is popular for vertical layouts in creative and some Asian markets. Corner radius changes perceived weight: larger radii feel modern and friendly, sharp corners feel formal. When choosing a special finish such as spot UV, foil, or textured paper, add at least one test print to verify how the finish affects legibility and color.
Practical examples
Example 1: An American consultant attending local networking events. Use US card dimensions for wallet compatibility and quick exchange. Keep type sizes large enough for legibility: name at 10 to 12 point, supporting text 7 to 8 point as a minimum.
Example 2: A London-based sales rep who travels to EU clients. Use the UK standard size so cards fit local holders and match client expectations. If you include two languages, the slightly taller format helps stack bilingual lines without feeling cramped.
Example 3: A Tokyo startup hiring locally and exchanging cards in formal meetings. Use common Japanese sizes and present cards with both hands. The printed layout should respect Japanese typography conventions and vertical alignment if you choose a portrait format.
Checklist before you hit print
- Confirm the final trimmed size with your printer and choose the regional standard if you will hand cards internationally.
- Set bleed (3 mm) and safe area (3 mm), or 0.125 inch if your printer asks for imperial units.
- Work in CMYK, 300 DPI, and embed fonts in the exported PDF.
- Order a printed proof or a small batch before a large run, especially for custom sizes or special finishes.
- Consider how recipients will store or scan the card, and place critical data and QR codes within the safe area.
After distribution: capture and organize contacts
Whatever size you choose, make a plan to digitize cards after an event to preserve contact data. Use a business card scanning app to capture details quickly and keep names and notes tied to the right meeting. Digitizing also reduces the chance of cards getting lost in pockets or drawers.
When in doubt, pick the local standard. It reduces printing cost, avoids storage problems for recipients, and keeps your layout predictable.
Decide on the size first, then design to that canvas. If you expect to work across multiple regions, create two templates sized for the most common formats you need. Test with printed proofs, verify bleed and safe areas, and include a simple digitization plan so those new contacts end up where you can use them.
