Barcode Types Explained
Code 128

High-density barcode that can encode all ASCII characters. Most versatile and commonly used.

Code 39

Simple barcode that encodes letters, numbers, and some symbols. Widely supported but less dense.

EAN-13

International product barcode standard. Used on most retail products worldwide.

UPC

North American product code standard. Common in US and Canada retail.

Usage Tips
  • Printing: Use higher bar width (3-5px) for better print quality
  • Digital: Lower bar width (1-2px) works well for screen display
  • Scanning: Ensure adequate quiet zones (white space) around barcode
  • Testing: Always test with your intended scanner before production use

Frequently Asked Questions

Everything you need to know about creating professional barcodes

Which barcode format should I choose for my application?

Code 128 is best for general purpose use with letters and numbers, offering high data density and excellent readability. Code 39 works well for simple alphanumeric data and is widely supported by older systems. EAN-13 and UPC are specifically designed for retail products with standardized product identification. Choose your format based on scanning equipment compatibility, data requirements, and intended application environment.

What size should I make my barcodes for printing?

For reliable printing and scanning, use width 3-5 and height 80-100px as your baseline. Smaller sizes (width 1-2, height 30-50px) work well for small labels and tight spaces, while larger sizes (width 5-8, height 100-150px) are ideal for packaging and long-distance scanning. Consider your printer resolution, scanning distance, and label material when determining optimal sizing.

How can I ensure my barcodes will scan properly?

Success depends on several key factors: maintain adequate white space (quiet zones) around the barcode edges, use high contrast with black bars on white or light backgrounds, choose appropriate sizes for your scanning distance and equipment, ensure print quality remains crisp without smudging or blurring, and always test with your actual scanning equipment before mass production. Environmental factors like lighting and scanner angle also affect readability.

Can I use colors other than black for my barcodes?

While black bars on white backgrounds provide optimal contrast and compatibility, dark colors like navy blue or dark brown can work with light backgrounds. Avoid red bars as many scanners use red light and cannot read red markings. Light colors, pastels, and low-contrast combinations should be avoided. When in doubt, stick with traditional black-and-white for maximum reliability across all scanning systems.

How much data can different barcode formats hold?

Code 128 can encode up to 80 characters including letters, numbers, and symbols, making it ideal for complex data like serial numbers. Code 39 handles up to 43 characters but is limited to alphanumeric data and some symbols. EAN-13 holds exactly 13 digits for product identification, while UPC codes contain 12 digits. Choose based on your data complexity and length requirements.

What file format should I download for different uses?

For professional printing, choose PNG for crisp edges and transparency support, or SVG for infinite scalability without quality loss. JPEG works for quick digital sharing but may introduce compression artifacts. PNG is ideal for labels and packaging, SVG excels for large format printing and professional graphics, while JPEG suits basic digital applications where file size matters more than perfect quality.

Will my barcodes work with smartphone scanner apps?

Most smartphone apps can read common formats like Code 128, Code 39, EAN-13, and UPC codes effectively. However, smartphone cameras may struggle with very small barcodes or poor lighting conditions. For mobile scanning, ensure adequate size (minimum 1 inch wide), good contrast, and clear printing. Consider that smartphone apps may have different capabilities than dedicated barcode scanners used in commercial environments.
