What size is an ID card? ID card dimensions explained
The standard ID card is a CR80: 3.375 x 2.125 inches (85.6 x 54 mm), the same rectangle as a credit card, normally 30 mil (0.76 mm) thick. The dimensions come from the ISO/IEC 7810 ID-1 standard, which is why a CR80 card fits off-the-shelf holders, lanyards, slot punches, and swipe or tap readers.
Standard ID card sizes
| Format | Inches | Millimeters | Typical thickness | Common use |

| CR80 | 3.375 x 2.125 in | 85.6 x 54 mm | 30 mil (0.76 mm) | Standard printed ID / access card |
How is an ID card different from a name badge?
An ID card is credit-card size (CR80) and usually carries a photo, name, title, and sometimes an access chip or barcode. A name badge is a different product and a different shape — the common sizes are 1 x 3 in, 1.5 x 3 in, and 2 x 3 in — meant to be read across a room rather than scanned at a reader. Many workplaces use both: a name badge for recognition and a CR80 ID card for access.
Portrait or landscape?
Photo ID cards are most often portrait (taller than wide) so the photo sits above the name, but CR80 cards print either orientation. If your card will be punched for a reel or lanyard, leave a clear margin at the top so the slot does not cut through text or the photo.
What thickness should I pick?
30 mil is the durable standard — rigid enough for daily swiping, tapping, and slot punching without bending. You can order custom CR80 ID cards here.
