How to make a QR code for your business card or poster

QR codes are everywhere — restaurant menus, business cards, shop windows, event posters. If you want to put a URL, phone number, or contact details on anything physical, a QR code is the fastest way to bridge print and digital.

This guide shows how to create a professional-looking QR code with your logo and brand colors in about two minutes, entirely free.

What can a QR code contain?

Most people use QR codes for website URLs, but they can encode almost anything:

• Website URL — https://yourwebsite.com
• Phone number — tel:+919876543210
• Email address — mailto:you@example.com
• WhatsApp message — https://wa.me/919876543210
• Plain text — your address, a discount code, instructions
• Wi-Fi credentials — so guests can connect without typing a password

Creating your QR code

Open QR Studio Pro and follow these steps:

1. Enter your content Type or paste your URL, phone number, or other content into the text input at the top. The QR code updates in real time as you type.

2. Choose a style The style presets change the shape of the QR modules (the small squares). Options include Square (classic), Rounded, Dots, and Diamond. Rounded and Dots look more modern and work well on business cards.

3. Set your colors Click the foreground color swatch to set the QR code color — this should match your brand. The background can be white, a light color, or transparent (for placing on a colored background).

4. Add your logo Click the logo upload area and select your logo file. The tool places it centered in the QR code with a white background cutout. Use the size slider to adjust how large the logo appears.

5. Choose error correction When you add a logo, set error correction to H (High). This allows up to 30% of the QR code to be covered while still scanning correctly — the logo sits in that covered area.

6. Set the output size For print use (business cards, posters), set size to at least 512px. For screens and social media, 300px is fine.

7. Download Click SVG for print — SVG is vector format and will look sharp at any size, from a business card to a billboard. Click PNG for digital use.

Tips for a QR code that always scans

High contrast is essential. Dark code on a light background scans reliably. Avoid low-contrast combinations like dark gray on black, or yellow on white.

Don’t make it too small. On a business card, a QR code should be at least 2cm × 2cm. Smaller than that and some phones will struggle.

Test before printing. Scan your QR code with at least two different phones before sending anything to print. Try both the default camera app and a dedicated QR scanner.

Keep the URL short. Long URLs create denser QR codes with more modules, which are harder to scan. Use a URL shortener like bit.ly or your own branded short domain.

Leave a quiet zone. QR codes need white space around them — at least 4 modules wide on each side. Don’t let other design elements crowd the edges.

QR code for a business card

For a business card, I recommend:

• Style: Rounded or Dots (looks more refined at small sizes)
• Error correction: M or H
• Size: 512px minimum for download, then scale in your design software
• Format: SVG for the designer, PNG if you’re placing it yourself
• Content: Your website URL or a link to your digital business card

QR code for a poster or banner

For large format print:

• Size: 1024px download
• Format: SVG (essential for large print — PNG will pixelate)
• Error correction: H (allows for some damage to the physical print)
• Colors: Black on white is the most reliable — only add color if your printer can guarantee accuracy
