What Size is an ID Card?

ID Card Sizes

When designing an ID card or purchasing badge accessories, it’s important to know the size of an ID card. There are three primary ID card sizes available:

ID Card Dimensions in Inches

CR80: The standard, most popular ID card size is 3.375″ x 2.125″. The CR80 card is also the same size as a credit card.

CR79: Slightly smaller than a standard size card, the CR79 card is 3.303″ x 2.051″. CR79 cards typically have an adhesive back and are commonly used for printing and adhering to a clamshell proximity card. Not all card printers are capable of printing on a CR79 card.

CR100: The CR100 card is 42% larger than a standard card, measuring 3.88″ x 2.63″. Often called “oversize” or “military-size” cards, CR100 cards are designed to be easy to see from a distance. Very few card printers are capable of printing on a CR100 card.

Tip: When designing a card, you may or may not be able to print to the very edge of the card. Direct-to-card ID card printers leave a small unprinted border around the perimeter of the card. If you are using a retransfer printer, however, you can print over the edge of the card with no issues.
