QR Codes on Business Cards: A Practical Guide
Updated July 2026 · 4 minute read
A business card has one job — getting someone from a handshake to your work — and a QR code shortens that trip from "I'll type this URL later, maybe" to one scan on the spot. But card real estate is tiny and print shops are unforgiving, so the details matter more here than almost anywhere else you'd put a code.
Decide what the code should open
Pick one destination — the thing you most want a new contact to see:
- Your portfolio or website — the classic choice for freelancers and creatives.
- Your LinkedIn profile — ideal for corporate networking; the app usually opens directly.
- A booking/calendar link — powerful for consultants: "scan to grab time with me."
- A link-in-bio page — one page listing everything, if you truly can't choose.
Whatever you pick, use the shortest clean URL you have. Long URLs stuffed with tracking parameters produce dense, fussy codes that are harder to scan at small sizes — and small is exactly what a business card forces.
Minimum size: don't go below 0.8 inches
Codes are scanned from close range on a card — usually 4 to 10 inches — so they can be smaller than poster codes. But there's a floor: below roughly 0.8 × 0.8 inches (2 × 2 cm), many phone cameras struggle to focus, especially older ones. Aim for 0.8 to 1 inch. If your design can't spare that, put the code on the back of the card at a comfortable size instead of shrinking it into a corner of the front.
Placement and breathing room
- Back of the card is the sweet spot: full size available, doesn't fight your name and title for attention, and a short caption ("Scan for my portfolio") tells people why to bother.
- Quiet zone: leave a margin of empty background around the code — at least the width of 4 of the code's little squares. Design elements crowding the code confuse scanners.
- Never wrap the code around a fold or place it over a photo, texture, or gradient.
Colors and card stock
Dark code on light background remains the rule. With the QR Quick Pick generator you can match your brand color — a deep brand navy or forest green works fine — but test anything lighter than a mid-tone. Two print-specific warnings: glossy card stock creates glare that can defeat scanning under overhead light (matte or soft-touch finishes scan better), and metallic or foil inks look fantastic while scanning terribly. If you want foil, foil the logo, not the code.
Download at high resolution
Print shops typically want 300 DPI artwork. A 1-inch printed code at 300 DPI needs only about 300 pixels, but there's no downside to giving your designer more: download the 1024×1024 PNG and let them scale it down. Scaling down keeps edges crisp; scaling a small image up makes them mushy, and mushy edges are the top cause of print codes that scan poorly.
The test that saves a reprint
Before ordering 500 cards, print one at home at actual size, in the actual colors, and scan it with a couple of different phones — including one with an older camera if you can find one. Thirty seconds of testing beats a box of expensive coasters.
