What is the Standard ID Card Size?

When it comes to ID card sizes, the most widely accepted and used dimension is the CR80 format. The CR80 card, also known as the “credit card size,” is the standard in the industry. It has a dimension of 3.375 inches (85.6 mm) in width and 2.125 inches (54 mm) in height. This size is similar to that of a standard credit or debit card, making it convenient to carry in wallets and cardholders.

Variations in ID Card Sizes

While the CR80 format is the most common, there are a few variations in ID card sizes used for specific purposes. These variations include:

  1. CR79: Slightly smaller than the CR80, the CR79 card measures 3.303 inches (83.9 mm) in width and 2.051 inches (52 mm) in height. It is often used for proximity cards and smart cards.
  2. CR100: On the larger side, the CR100 card measures 3.88 inches (98.5 mm) in width and 2.63 inches (66.7 mm) in height. It offers more space for additional information and is commonly used for event badges or oversized identification cards.

Importance of Adhering to Standard Sizes

Adhering to standard ID card sizes is crucial for several reasons:

  1. Compatibility: Most ID card printers and accessories are designed to accommodate the CR80 format. Using the standard size ensures compatibility and makes the printing process hassle-free.
  2. Convenience: The credit card-sized ID cards easily fit into wallets, cardholders, and ID badge accessories. They are convenient to carry and less likely to get damaged.
  3. Interchangeability: Standard-sized ID cards are interchangeable, meaning they can be used across various systems and organizations without any issues. This flexibility allows for easier integration and identification processes.
  4. Cost Efficiency: Standard-sized cards are readily available, and the materials required for printing them are commonly stocked. This availability often results in cost savings for organizations compared to custom-sized cards.


Understanding the standard ID card size is essential for anyone involved in the design, printing, or usage of identification cards. The CR80 format, similar to a credit card, is widely accepted and compatible with most ID card systems. While there are variations in sizes like CR79 and CR100, adhering to the standard size offers convenience, compatibility, and cost efficiency. So, whether you’re obtaining a driver’s license, an employee ID, or any other identification card, remember the importance of the proper ID card size.
