Use a 20–25 mm QR code on most business cards

For a standard business card, make the QR code 20–25 mm (0.8–1.0 in) wide. Reserve 18–20 mm for a short, simple URL that passes a real print test; use 25–30 mm for a denser vCard, a logo treatment, textured stock, or a card scanned from farther away. The measurement must include the four-module quiet zone around the code. Export SVG, place it at final size without stretching, print one proof on the actual stock, and test that proof from 30–50 cm with both iPhone and Android before ordering the full run.

  • 20–25 mm is the practical default for most cards.
  • Dense vCards and difficult print stock need more space.
  • Test the final-size proof, not only the file on screen.

大多数名片使用 20–25 毫米二维码

标准名片上的二维码建议做成 20–25 毫米宽。只有内容很短、并且通过实际印刷测试的网址二维码，才考虑缩到 18–20 毫米；vCard 字段较多、带 Logo、纸张纹理明显，或扫码距离更远时，应放大到 25–30 毫米。尺寸必须包含二维码四周至少四个模块的留白区。请导出 SVG，按最终尺寸放入版面，不要拉伸变形；用实际纸张先印一张样张，再分别用 iPhone 和 Android 从 30–50 厘米距离测试，确认后再批量印刷。

  • 20–25 毫米是大多数名片的实用默认值。
  • vCard 越密、印刷条件越难，尺寸越要放大。
  • 要测试最终印刷样张，而不是只扫屏幕文件。
How we verify this guide

Before this page is included in the public guide directory, its examples are compared with the payload produced by the linked QRFlow generator and with the export and scan-readiness controls available in the current build. Camera, lighting, paper, print size, and destination apps can still change the result, so important print runs should always be tested on the final material and real devices.

Quick steps
  1. Estimate the QR content: Decide if the QR will contain a short URL or a dense vCard; longer content needs more space.
  2. Pick a size range: Start with 20-25 mm for business cards; move to 25-30 mm for longer data or farther scans.
  3. Keep the quiet zone: Leave a blank margin of at least 4 modules around the code and avoid busy backgrounds.
  4. Export and test: Download SVG, print a test card, and scan from 30-50 cm on both iPhone and Android.

Use cases & print ideas

vCard Contact QR Print Use Cases
Use these print examples when the next step should be saving a contact, not typing details or visiting a plain web page.
Redirect QR Code Use Cases
Use Redirect QR for a controlled destination path; only hosted dynamic QR lets the printed asset stay fixed while the destination changes after launch.

Short answer: use 20-25 mm for most business cards, stay closer to 18-20 mm only for short URLs, and move up to 25-30 mm for denser vCards.

This guide is written for people printing business cards (visiting cards / name cards) and wanting reliable scans, not theory.

Standard business card dimensions (US/EU/JP)#

Business card dimensions affect how much clean space you have for the QR (and how large you can print it without crowding the design).

  • US: 3.5 × 2 in (88.9 × 50.8 mm)
  • EU/UK: 85 × 55 mm
  • Japan: 91 × 55 mm

Tip: the back of the business card is usually the easiest place to keep a clean quiet zone. See placement tips.

The short answer#

  • Aim for 20-25 mm (0.8-1.0") QR size on a standard card.
  • Keep a quiet zone (blank margin) of at least 4 modules around the code.
  • Print in high contrast (dark on light), avoid glossy reflections if possible.

How big should a QR code be on a business card?#

For most business cards, 20-25 mm is the safest range. Short URL QR codes can live closer to 20 mm, while vCard / contact QR codes usually need 22-25 mm because the payload is denser.

If people scan from farther away, such as a badge holder or table stand, move up to 25-30 mm.

What is the minimum QR code size for a business card?#

A very short URL QR can sometimes work at around 18-20 mm, but that is the lower edge. For production prints, 20-25 mm is safer, especially if you use a vCard, add a label nearby, or print on textured / glossy stock.

Practical sizing table#

Use the larger sizes if your QR content is long (vCard, long URLs) or if people scan from farther away.
Use caseRecommended size
Short URL / profile link20-22 mm (0.8-0.87")
vCard / longer payloads22-25 mm (0.87-1.0")
“Scan from a lanyard / event badge distance”25-30 mm (1.0-1.2")

SVG vs PNG#

For printing, download SVG so the edges stay sharp at any size. PNG is fine for screens, but can blur when resized for print.

Quick print checklist#

  • Use a short, stable destination (avoid tracking links that may expire).
  • Test scan from 30–50 cm (12–20″) in indoor lighting.
  • Avoid placing the QR on a busy background.
  • Don’t crop the quiet zone when exporting or placing in design tools.

Quick answers

Common questions

What size should a QR code be on a business card?
Use 20-25 mm for most cards, and go larger for long vCard data or longer scan distances.
What is the minimum QR code size for a business card?
About 18-20 mm can work for a short URL, but 20-25 mm is safer for real prints, especially for vCard QR codes.
How much quiet zone do I need?
Leave a blank margin of at least 4 modules around the code.
Does glossy print hurt scanning?
Yes. Glossy reflections can reduce contrast, so test before bulk printing.
