Understanding the Most Common ID Card Sizes for Your Printing Needs

When planning to issue ID cards, one of the most important decisions you’ll face is choosing the right card size. Whether you're printing badges for staff, access cards for secure facilities, or passes for events, selecting the correct dimensions ensures your cards are both functional and visually effective.

Below, we break down the three most frequently used ID card sizes and how they’re typically applied across different industries.

1. CR80 – The Standard ID Card Size

Dimensions: 3.375" x 2.125" (85.6 x 54 mm)

The CR80 card is the industry standard and by far the most widely used size. Roughly the same dimensions as a credit card, it fits easily into wallets, badge holders, and most ID card accessories.

Common Applications:

  • Employee identification badges

  • Membership cards for clubs, gyms, and organizations

  • Access cards for buildings and facilities

  • Financial cards like credit or debit cards

Why Choose CR80:

  • Highly Compatible: Works with nearly all ID card printers and accessories

  • Easy to Carry: Slim and compact, ideal for everyday use

  • Multi-Purpose: Suitable for everything from security to branding

2. CR79 – Designed for Adhesive Backing and Specialized Use

Dimensions: 3.303" x 2.051" (83.9 x 51.8 mm)

Slightly smaller than the CR80, the CR79 is often made with an adhesive back and is designed to stick onto larger cards like clamshell proximity cards. These cards are often used when a photo ID needs to be combined with another technology card.

Common Applications:

  • Custom labels for access cards

  • Photo overlays on proximity or smart cards

  • Removable or temporary identification badges

Why Choose CR79:

  • Adhesive Functionality: Easily affixed to other credentials

  • Ideal for Temporary Use: Great for environments where IDs may change frequently

  • Specialty Integration: Allows dual use with smart card technologies

3. CR100 – Oversized Cards for Maximum Visibility

Dimensions: 3.88" x 2.63" (98.5 x 67 mm)

The CR100 is significantly larger than the standard CR80, offering additional space for larger photos, titles, and security information. It's a smart choice for situations where clear, visible identification is essential.

Common Applications:

  • Visitor or contractor passes

  • Conference and event credentials

  • Security personnel badges

Why Choose CR100:

  • Enhanced Readability: Larger text and photos are easier to see from a distance

  • More Space for Details: Extra room for including names, departments, barcodes, or QR codes

  • Ideal for High-Visibility Settings: Great for environments that require quick recognition
