Those Square Barcode Things Are Actually Useful
QR codes had a weird reputation for a while. Seemed like a gimmick. But then menus went digital, contactless everything became normal, and suddenly those scannable squares were everywhere.
Turns out they're genuinely handy for connecting physical things to digital ones. Here's how to make them.
Creating a QR Code
Our QR Code Generator makes it simple:
- Enter what you want to encode (usually a URL)
- Adjust size if needed
- Download your QR code image
- Print it, share it, whatever
The whole process takes about 10 seconds.
What You Can Encode
QR codes aren't just for website links. You can encode:
URLs — The most common use. Scan to open a webpage.
Plain text — Any message up to a few thousand characters.
Contact info — Name, phone, email packaged for easy saving.
WiFi networks — SSID and password that let people join automatically.
Phone numbers — Scan to call.
Email addresses — Opens compose window with address pre-filled.
Different types work better for different situations.
Where QR Codes Actually Make Sense
After years of seeing QR codes used well (and badly), here's when they genuinely help:
Restaurant menus — COVID accelerated this, and many places kept digital menus. Saves printing costs and allows easy updates.
Business cards — Link to your portfolio or LinkedIn. Saves manual typing.
Product packaging — Link to instructions, warranty registration, or additional info.
Event materials — Conference badges linking to schedules, posters linking to sign-up forms.
Print marketing — Flyers and posters connecting to online content.
Networking — Share contact info or portfolios quickly.
Where They Don't Make Sense
QR codes aren't always the answer:
Already-digital contexts — A QR code in an email linking to a website is silly. Just use a regular link.
When a short URL works — Sometimes "example.com/menu" printed clearly is easier than a QR code.
Complex authentication — QR codes aren't secure by themselves. Don't use them for sensitive access without additional verification.
Making Them Work
A few practical tips from experience:
Test before printing — Scan your QR code with multiple phones before committing to a print run.
Give it room — QR codes need a white border (quiet zone) around them to scan reliably.
Don't make it too small — For print, at least 1 inch square. Bigger for things viewed from a distance.
Location URL matters — QR codes are permanent captures of URLs. If you might change the destination, use a redirect service or short link that you control.
Track if you care — Use a URL shortener with analytics if you want to know how many scans you get.
The Size Question
Bigger QR codes scan more easily, especially from further away.
For something held in hand (business card, product label): 1 inch minimum.
For something on a wall or table: 2+ inches.
For posters or large displays: proportionally larger. A QR code on a billboard needs to be huge.
