In modern life, cards are everywhere—from credit cards in your wallet to the ID badges used at work. While they may seem simple, these cards follow strict international standards, the most important being ISO/IEC 7810 for Identification Cards Physical Characteristics.
This guide provides a comprehensive breakdown of the ISO/IEC 7810 standard, covering major card formats like ID-1 (CR80), ID-2, ID-3, and ID-000. We will detail their physical characteristics, dimensions in both millimeters and inches, and common real-world applications.
ISO/IEC 7810: More Than Just Dimensions
ISO/IEC 7810 is an international standard that defines the physical characteristics of identification cards to ensure they work seamlessly across different systems worldwide. Beyond just specifying sizes (like ID-1 or ID-2), the standard sets rigorous requirements for materials, construction, and performance to guarantee reliability and durability in various environments.
Key physical indicators defined by the standard include:
•Structural Stability: Covers bending stiffness (to prevent snapping), warpage control, and dimensional stability, ensuring the card remains flat and functional over long-term use.
•Environmental Resistance: Specifies requirements for flammability, chemical resistance, heat resistance, and non-toxicity, allowing cards to withstand diverse working conditions.
•Surface Quality: Strictly limits surface distortions and adhesion/blocking to ensure high-quality printing, professional appearance, and the integrity of embedded RFID chips.
Core Card Size Comparison Table
For quick reference, we have compiled the primary card formats defined under ISO/IEC 7810 and their key specifications:
| Format | Dimensions (mm) | Dimensions (inch) | Common Applications |
| ID-1 (CR80) | 85.60 × 53.98 | 3.370 × 2.125 | Credit/Debit Cards, ID Cards, Driver’s Licenses, Hotel Key Cards, RFID Cards |
| ID-2 | 105 × 74 | 4.134 × 2.913 | Visas, French & Romanian ID Cards (Older versions) |
| ID-3 | 125 × 88 | 4.921 × 3.465 | Passport Booklets |
| ID-000 | 25 × 15 | 0.984 × 0.591 | SIM Cards |
Detailed Analysis of Card Formats
ID-1 (CR80): The Global Standard
The ID-1 format, commonly referred to as CR80, is the most recognizable card size in the world. Its precise dimensions are 85.60 × 53.98 mm (3.370 × 2.125 inches), featuring rounded corners with a radius of 2.88–3.48 mm (approx. 1/8 inch). This format is the gold standard for:
•Payment Cards: Credit cards, debit cards, and loyalty cards.
•Identification: National ID cards and driver’s licenses in most countries.
•Access Control: Hotel key cards, transit passes, and corporate RFID badges.
The nominal ID-1 thickness is 0.76 mm (30 mil), which provides the physical format required for many card applications. Compatibility with ATMs, POS terminals, or other systems also depends on the card technology, interface, and application requirements.
ID-2: The A7 Format Card
The ID-2 format measures 105 × 74 mm (4.134 × 2.913 inches), which corresponds to the A7 paper size. While less common today, it was historically used for French and Romanian identity cards and German ID cards issued before October 2010.
ID-3: The B7 Format for Passports
The ID-3 format measures 125 × 88 mm (4.921 × 3.465 inches), equivalent to the B7 paper size. This format is primarily used for passport booklets, providing enough surface area to accommodate biometric data and security features.
ID-000: The Miniature Format
The ID-000 format measures 25 × 15 mm (0.984 × 0.591 inches) with a slight 3mm bevel. Originally based on the ENV 1375-1 standard, its most prevalent application today is the physical size of SIM cards.
Conclusion
The ISO/IEC 7810 standard is the foundation of the identification card industry, providing a unified framework for design and manufacturing. By following this guide, you now have a clear understanding of ID-1 (CR80), ID-2, ID-3, and ID-000 formats.

FAQs
1. What is the standard thickness of an ISO 7810 card?
The most common thickness defined under ISO 7810 is 0.76 mm (30 mil). This is the universal standard for credit cards, most RFID cards, and PVC cards.
2. Is CR80 the same as ID-1?
Yes, CR80 and ID-1 refer to the exact same dimensions. CR80 is an industry term, while ID-1 is the formal designation used in the ISO/IEC 7810 standard. Both represent the 85.60 × 53.98 mm size.
3. What are the physical requirements for ISO/IEC 7810 compliance?
Compliance involves meeting strict criteria for bending stiffness, flammability, toxicity, chemical resistance, dimensional stability, and warpage. These ensure the card remains reliable and safe for users.
4. Why is the ISO/IEC 7810 standard important?
It ensures that cards follow consistent physical specifications, such as size and thickness. For manufacturers, this simplifies production and compatibility at the physical level; for users, additional card technologies and system standards determine whether a card works for specific applications.
