8 Types of QR Codes You Can Create
🔗 URL QR Code
The most common type. Encode any website URL so users can visit your page by scanning. Perfect for business cards, flyers, product packaging, and restaurant menus.
📶 WiFi QR Code
Let guests connect to your WiFi network without typing the password. The QR code encodes your network name, password, and encryption type. Ideal for offices, cafes, hotels, and Airbnbs.
👤 vCard QR Code
Create a digital business card. When scanned, the contact details (name, phone, email, company, website) are added directly to the phone’s contacts. Much more effective than paper business cards.
✉️ Email QR Code
Pre-fill an email with recipient address, subject line, and body text. Scanning opens the user’s email app ready to send. Great for customer support and feedback collection.
💬 SMS & 📱 WhatsApp QR Codes
Open a text message or WhatsApp chat with a pre-filled message. Used by businesses for quick customer communication, support lines, and marketing campaigns.
📞 Phone QR Code
Scanning triggers a phone call to your number. Simple and effective for “call us” on print materials.
💡 QR Code Best Practices
- Test before printing: Always scan your QR code with multiple phones before using it in print materials.
- Keep good contrast: Dark foreground on light background works best. Avoid low-contrast color combinations.
- Size matters: For print, use at least 2cm × 2cm (0.8in). For billboards, scale up proportionally.
- Add a call to action: Don’t just show a QR code — add text like “Scan to connect” or “Scan for menu”.
- Use SVG for print: SVG files scale to any size without losing quality — perfect for professional printing.
- Don’t over-customize: While colors are fun, extreme customization can reduce scan reliability.
QR Code Size Guide
The right QR code size depends on scanning distance:
- Business cards: 256×256px / 2cm minimum
- Flyers & brochures: 512×512px / 3–4cm
- Posters: 1024×1024px / 6–10cm
- Banners & signs: 2048×2048px / 15cm+
- Rule of thumb: The scanning distance should be 10× the QR code’s width
PNG vs SVG: Which Format to Download?
PNG is a raster image — great for digital use (websites, social media, email). Choose this for quick sharing and screen display.
SVG is a vector image — it scales to any size without losing quality. Choose this for print materials, professional designs, and large-format printing.
Make the Scans Measurable
A QR code only tells you what worked if the URL inside it is tagged. These kits handle the tagging, the register of campaigns, and the print standards that keep codes scannable.
