QR codes on business cards: the complete guide

7 August 2026 · Free QR Pro

A well-placed QR code turns a paper card into an interactive touchpoint — linking to your portfolio, saving your contact in one tap, or connecting to your LinkedIn.

What should your QR code link to?

• A vCard QR code — encodes your name, phone, email, and website directly into the code. When scanned, it prompts the user to save you as a contact. No URL required, works offline. Best for anyone in a customer-facing role.
• Your personal website or portfolio — a simple URL. Best for designers, developers, consultants, photographers.
• Your LinkedIn profile — best for corporate professionals who use LinkedIn as their primary professional identity.
• A link-in-bio page (Linktree, Carrd, etc.) — one link to all your profiles and booking links. Best for freelancers with multiple channels.

Tip: avoid encoding long LinkedIn URLs — they create very dense QR codes that can fail to scan. Use a URL shortener or your LinkedIn vanity URL (e.g. linkedin.com/in/yourname).

Size and placement

A business card is typically 85 × 54 mm (3.5 × 2 in). Your QR code should occupy no more than 25–30% of the card's area — roughly 20 × 20 mm minimum. Smaller than 15 × 15 mm is unreliable in poor lighting.

Back of card: the cleanest option. The back is usually blank, giving the QR code space to breathe without competing with your name and contact details.

Bottom corner of front: common in tech and design. Works well if you keep the front uncluttered. Place it in the lower right with a small label like "Scan to connect".

Choosing the right shape

Reliable for print: square (maximum data density), rounded square (clean, modern look), circle (distinctive, scans well).

Test carefully first: heart and star (both clip finder patterns), diamond (reduced effective area).

Rounded square is the most popular choice for business cards — it feels less rigid than a plain square while remaining highly scannable.

Colour and contrast

The QR modules must contrast strongly with the background — a ratio of at least 4:1 is recommended. Dark navy or charcoal on white works perfectly; light grey on white will fail. Inverted colours (light modules on dark background) work as long as contrast is maintained, but always test before printing.

Watch out: gold foil, metallic inks, and glossy lamination can cause reflection that prevents scanning. If your card uses these finishes, place the QR code in a matte area or use a matte lamination patch.

Download as SVG for printing

Always download your QR code as SVG when sending to a print shop. PNG files are pixel-based and will look blurry if scaled up. SVG is vector-based and prints sharply at any size — from a tiny card to a poster.
