How to Create a QR Code for Different Uses
For a Website or URL
Select the URL type, paste your website address (e.g., https://builddora.com), and click Generate. This is the most scanned type of QR code—used on business cards, flyers, product packaging, and social media profiles.
For WiFi
Select the WiFi type, enter your network name (SSID) and password. When customers or guests scan this QR code, they connect to your WiFi automatically without typing the password. Perfect for cafes, hotels, offices, and homes.
For WhatsApp
Select the URL type and enter: https://wa.me/YOURNUMBER (replace YOURNUMBER with your full number including country code, e.g., 923001234567). When scanned, it opens a WhatsApp chat with you directly.
For Business Cards (vCard)
Select the vCard / Contact type and fill in your name, phone, email, organization, and website. When someone scans this QR code, they can save your full contact information in one tap—the modern replacement for paper business cards.
For Instagram or YouTube
Select the URL type and paste your Instagram or YouTube profile link. People can scan and follow you instantly without typing your handle.
What Size Should You Use for Your QR Code?
The size of your QR code depends on where you plan to use it and how far away it will be scanned.
| Where You Will Use It | Recommended Size | Minimum Scan Distance |
|---|---|---|
| Business card | 2 × 2 cm (use 256px) | ~20 cm |
| Flyer or brochure | 3 × 3 cm (use 256px) | ~30 cm |
| Table tent / menu | 4 × 4 cm (use 256px) | ~40 cm |
| A4 poster | 6 × 6 cm (use 512px) | ~60 cm |
| Shop window | 10 × 10 cm (use 512px) | ~1 meter |
| Large banner / billboard | 20 × 20 cm or larger | 2+ meters |
Rule of thumb: Scan distance = 10 × QR code size. A 5cm QR code can be scanned from 50cm away.
Common Mistakes to Avoid When Creating a QR Code
Avoid these common pitfalls to ensure your QR code works perfectly:
- Too Small: QR codes under 2cm are often unscannable. Always test before printing.
- Low Contrast: Avoid light QR codes on light backgrounds or dark on dark. Use strong contrast (e.g., dark code on a white background).
- Wrong URL: Always double-check that your URL works before generating and printing.
- No Testing: Always scan your QR code with multiple phones before printing at scale.
- Broken Links: If you change your URL later, your printed QR codes will stop working. Use a reliable permalink or static URL.
