The Standard ID Card Sizes

When you are in the market for ID cards, you might come across cards with numbers such as CR80, CR79, and CR100. At first, they might be confusing, but they are simply the card sizes you should know about.

These sizes align with the International Organization for Standardization (ISO). Such standardization is important so that different cards can fit in card readers, badge holders, and cardholder wallets. As you can see, you get the best convenience and interchangeability when working with various systems and settings.

1. CR80: The Most Common ID Card Size


This is what you would mostly get commonly being used in many applications. Its number means it measures  2.125″x3.375″. This is according to the ISO/IEC 7810 standard.

This card size is considered the gold standard for several identification purposes thanks to its compatibility and versatility. The best part is that it should fit into standard wallets easily. This makes using it more often quite easy without worrying how you would carry it.

Several accessories can work well with these cards. As such, you should end up with easy access and efficient identification.

As for applications, the cards work best for employee identification, student ID cards, event passes, access control, and membership cards. This shows just how effective the card size is for many uses.

2. CR79: Specialized ID Card Sizes


Beyond the CR80, we have the CR79. This is more of a specialized ID card size. The card measures  2.051″x3.303″. Compared to the CR80, you can see that it is smaller in dimensions. Being smaller makes it a good pick for those who might be seeking a compact ID card size.

Besides the size, you can also consider its portability, aesthetics, and branding considerations. Since the cards are smaller, they are more portable and practical for daily use. Of course, those with minimalist wallets will enjoy such smaller cards.

We see such cards mostly being used in exclusive membership clubs, where people want to keep the cards discreet. Also some businesses may also consider using them for employee badges ensuring they fit comfortably in purses and wallets.

3. Oversized ID Cards: CR100 and More


The CR100 is bigger than the other two options mentioned above. Measuring  2.63″x3.88″, it is big enough to set it apart.

Such cards are best for making a visual impact. Expect them to capture the attention of most people. That is why brands might include logos and images to leave a lasting impression on potential clients.

You may also find that industries favor these cards mostly for making a statement and enhancing branding. They also work quite well for conferences and conventions. At such events, we expect that having such a huge card leaves you with more visually striking credentials to make it easier for identification.

Being oversized can also help you get options such as customization. Some of the common customization options include having holographic foils, unique shapes, and embossing. This is all vital to give you the best experience using the cards.

4. Mini ID Cards


You may also come across the mini ID cards. They might not have the same standardization as the usual ID cards mentioned above. Nevertheless, they can be good for you. They are mostly used for serving specific purposes in a company.

Being small has other perks, such as attaching them to the key holders and carrying them around as key tags. They also offer the best portability and ease of use because of such a feature.

These mini ID cards can work for various industries and settings. A good example is a brand using them for loyalty programs or membership cards. They are still effective for access control and attendance tracking.
