When printing ID cards using an ID card printer, it’s important you purchase the correct size of card.
Our guide gives you a look at three of the most common card dimensions.
What size is a standard ID card?
- CR80 (86mm x 54mm) – This the standard size of most ID cards and is the most popular
- CR79 (84mm x 52mm) – These cards are slightly smaller and are often used for access control
- CR100 (100mm x 70mm) – These are the largest size for ID and can display lots of information
Now, let’s have a more in-depth look at each of these card types.
Let’s check out the most popular size of ID card first – the CR80. This is the “standard” size for a plastic card and measures in at 86mm x 54mm. It’s exactly the same size as a standard credit card and the size accepted by the vast majority of ID card printers.
These cards come in a variety of materials including PVC, recycled plastic, biodegradable composite and paper.
Slightly smaller at 84mm x 52mm is the CR79 card type. These ID cards are designed to fit snugly into a protective clamshell, with many of these cards already having an adhesive back for additional support.
You’ll find that quite a few access control cards are CR79 spec depending on the manufacturer and model in question, and are sometimes better protected to ensure they are more durable in tough outdoor environments.
It’s important that you check that your ID card printer can handle CR79 cards if that is what you require; not all machines are able to accept them.
Finally, the largest of the common ID card sizes, the CR100. These ID cards are usually thick and measure at 100mm x 70mm. These cards are ideal in environments where individuals need to be identified quickly and easily such as at conventions, trade shows and outdoor events or concerts.
They’re also a great idea if you need to display lots of information. However, the cards themselves as well as their associated printers are more costly than CR80 or CR79 cards and are usually produced by an in-house printing service. Talking of which…
What does ID card thickness mean?
As well as size, cards are produced in a range of thicknesses. ID card thickness is measured in “mils” which is not a metric term but is equal to 0.001 inches. For example, a standard card thickness is 30 mil, which translates to 0.003 inches.
Most ID card printers have either automatic or manual card adjuster that allows you to change the card thickness, so whether it’s a CR78 or CR80 card, you shouldn’t run into any issues.
