What can I encode in a QR code label?

URLs, contact information (vCards), plain text, email addresses, phone numbers, Wi-Fi credentials, and geographic coordinates. URLs are the most common use case.

What size should a QR code label be?

At minimum 1" x 1" for reliable scanning. 2" x 2" is ideal for labels that need to be scanned from a distance. The QR code itself should have a quiet zone of at least 4 modules (the small squares) on all sides.

Can I add text alongside a QR code?

Yes. printshi lets you combine QR codes with text elements on the same label. A common layout is the QR code on the left with a description and URL on the right.

Do QR codes work in black and white?

Yes. QR codes are designed to be black on white for maximum contrast and scan reliability. Colored QR codes work but may have lower scan rates. Always test colored codes before printing a batch.

Can I generate QR codes without an internet connection?

Yes. printshi generates QR codes locally in your browser — no server required. This means your URLs and data are never uploaded anywhere.

How long do QR code links last?

Static QR codes (encoding a URL directly) last forever — as long as the destination URL is active. printshi creates static QR codes, so there's no subscription or expiration.

How to Make QR Code Labels

Last updated: April 12, 2026

QR codes have moved far beyond restaurant menus. Today they're used on product packaging, asset tags, inventory labels, business cards, event tickets, and marketing materials. A QR code label combines scannable technology with printed information : linking a physical item to a website, document, app, or database entry. This guide shows you how to create and print QR code labels at home.

What Can a QR Code Encode?

A QR code is simply a two-dimensional barcode that stores data. When someone scans it with their phone camera, the data is decoded and acted upon. Common types of data you can encode:

URL : Link to a website, product page, or landing page. The most common use case.
Plain text : Display a message, serial number, or description when scanned.
vCard (contact info) : Share a name, phone number, email, and address instantly. Great for business card labels.
Wi-Fi credentials : Let guests connect to your network by scanning. Perfect for labels on routers, office signs, or Airbnb instructions.
Email address : Opens the user's email app with a pre-filled "To" field.
Location (GPS coordinates) : Opens a map to a specific location. Useful for event labels or asset tracking in large facilities.

How Big Should a QR Code Label Be?

QR code size depends on two factors: the amount of data encoded and the distance from which it will be scanned.

Minimum size: 0.8″ × 0.8″ (2 cm × 2 cm) : The smallest practical QR code for close-range scanning (held up to a phone). Works for short URLs or simple text.
Standard label size: 1″ × 1″ to 2″ × 2″ : Reliable scanning from arm's length. This is the sweet spot for most labels.
Signage: 4″ × 4″ or larger : For QR codes on posters, window signs, or displays meant to be scanned from several feet away.

The general rule: the QR code should be at least 1/10th of the scanning distance. If someone will scan it from 10 inches away, the code should be at least 1 inch wide.

Popular Uses for QR Code Labels

Asset and Inventory Tracking

Businesses use QR code labels to track equipment, tools, IT assets, and inventory. Each item gets a unique label with a QR code linking to a database entry, spreadsheet row, or asset management page. When an employee scans the code, they see the item's details, location history, maintenance schedule, or checkout status.

Product Packaging

QR codes on product labels can link to detailed product information, usage instructions, recipe ideas, or customer reviews. For food products, they can link to full nutritional information or sourcing details that don't fit on a small label.

Marketing and Promotions

Add QR codes to sticker labels and place them on packaging, receipts, or promotional materials. Link to discount codes, loyalty programs, social media pages, or contest entries. Because QR codes are trackable, you can measure how many people scanned each label.

Moving and Storage

When packing boxes for a move, label each box with a QR code that links to a list of the box's contents. This saves you from writing inventories on the outside of every box and makes finding specific items much faster.

Design Tips for QR Code Labels

Maintain a quiet zone. Leave white space (at least 4 modules wide) around the QR code. If text or graphics crowd too close, scanners may fail.
Keep high contrast. Black code on a white background scans most reliably. Avoid placing QR codes on dark, busy, or patterned backgrounds.
Add readable text below the code. Include a human-readable version of the URL or a call-to-action like "Scan for details" so users know what to expect.
Test before printing. Always scan the QR code with at least two different phone cameras before printing a full batch. Test at the intended scanning distance.
Don't scale down too aggressively. If the individual modules (the small squares that make up the QR code) become less than 0.5mm, many cameras will struggle to decode them.

Create Your QR Code Labels

Our free label maker has a built-in QR code generator. Type in any URL, text, or contact information, and the QR code is created directly on your label : no external tools needed. Combine QR codes with text, custom sizing, and batch printing for a complete labeling solution.
