为名片设计QR Code
Space-constrained design: fitting QR codes on 85x55mm cards with contact data, brand identity, and scannability.
Designing QR Codes for Business Cards
Business cards present a unique design challenge: fitting a scannable QR code into an 85x55mm space alongside name, title, contact details, and branding.
Choosing the Right Content
| Content | Format | Typical Size |
|---|---|---|
| Full contact info | vCard | 200-400 bytes |
| Basic contact | MeCard | 80-150 bytes |
| Website URL | URL | 30-60 bytes |
| LinkedIn profile | URL | 40-60 bytes |
| Digital card link | URL | 25-50 bytes |
Recommendation: For physical business cards, a URL QR code linking to a digital contact page is often better than encoding full vCard data. The URL creates a smaller QR code (Version 2-3 vs Version 8-12 for vCard) and allows you to update your information without reprinting cards.
Size and Placement
On a standard 85x55mm card:
- Minimum QR code size: 15mm (for Version 2-3, close-range scanning)
- Recommended size: 20-25mm
- Maximum practical size: 30mm (leaves space for other content)
Common placement positions: - Bottom-right corner - Centre of the back side - Alongside the name on the front
Error Correction
Business cards are handled, bent, and stored in wallets — use EC Level M minimum. If embedding a logo, use EC Level H.
Design Integration
- Match the QR code colour to the card's design palette
- Maintain the quiet zone — the most common error on business cards
- Add a subtle call-to-action ("Scan to connect" or "Save my contact")
- Consider rounded modules for a softer look
Key Takeaways
- URL QR codes (linking to a digital card page) are more practical than vCard
- Minimum 15mm, recommended 20-25mm on standard 85x55mm cards
- EC Level M minimum, EC Level H if embedding a logo
- Placement: bottom-right corner or centre back is most common
- Add a CTA so recipients know what scanning will do
