I represent a midsize museum, so digital membership cards are not fiscally possible for us. Plastek supplies us with tangible membership cards that our members proudly show as a patron of the arts. We've been working with Plastek for several years with many template changes and each time they have delivered a beautiful and affordable product that our members enjoy. Cindy is very responsive and a pleasure to work with ensuring an easy ordering process. We highly recommend Plastek!

I run a company that has used Plastek and their outstanding rep Cindy for my last three projects and will not use another company. Cindy has done such an incredible job with from start to finish. Artwork dept is great, revisions (if requested) are done quickly, prices are extremely fair and received OUTSTANDING customer service when I needed a particular project delivered - they got it to me earlier than projected.

The only company I’ll trust for my clients’ cards.

When you order custom plastic cards, thickness plays a major role in how they look, feel, and perform. Whether you need gift cards, membership cards, business cards, or credit card style cards, the right thickness affects durability, function, and compatibility with point of sale (POS) systems.

The standard credit card thickness is 30 mil, which equals 0.76mm or 0.030 inches. This measurement follows the ISO/IEC 7810 standard, which keeps cards compatible with ATMs, card readers, and POS terminals. It is the most common choice for payment cards, hotel key cards, and premium plastic gift cards.

What Is the Standard Credit Card Thickness?

A standard credit card is 30 mil thick, equal to 0.76mm. The same specification applies to debit cards, bank cards, and ATM cards, so any card meant to run through a reader or POS terminal is typically produced at 30 mil.

Card TypeThickness (mil)Thickness (mm)Common Uses
Credit and Debit Cards30 mil0.76mmPayment, ATM, POS
Business Cards12 mil – 20 mil0.30mm – 0.50mmNetworking, premium branding
Gift Cards20 mil – 30 mil0.50mm – 0.76mmRetail, promotions
Loyalty and membership cards20 mil – 30 mil0.25mm – 0.76mmAccess, rewards, identification
Event passes and bandges10 mil - 20 milVariesTemporary, short term use

How Thick Are Credit Cards in Inches and Millimeters?

A standard credit card measures 30 mil, which is 0.030 inches or 0.76mm. "Mil" refers to one thousandth of an inch, not a millimeter, which is a common point of confusion. Plastek offers several thicknesses to match different budgets and use cases.

10 Mil Thickness (0.25mm)

  • Use Case: Temporary cards, mailers, promotional inserts, and lightweight passes.
  • Pros: Lowest cost, flexible, easy to mail.
  • Cons: Least durable, not suited to heavy or repeated use.

12 Mil Thickness (0.30mm)

  • Use Case: Short run business cards and light duty membership cards.
  • Pros: affordable, slightly sturdier than 10 mil.
  • Cons: Still relatively thin for high touch applications.

20 Mil Thickness (0.50mm)

  • Use Case: Gift cards, loyalty cards, and mid tier membership cards.
  • Pros: Solid balance of durability and cost.
  • Cons: Thinner than a standard payment card

30 Mil Thickness (0.76mm)

  • Use Case: Credit card style cards, hotel key cards, and premium gift or ID cards.
  • Pros: Most durable, matches the ISO credit card standard, best POS and encoding compatibility.
  • Cons: Highest cost compared to the standard options.

Understanding Card Thickness in Different Units

Card thickness is listed in mil, but it helps to see the equivalent in millimeters and inches.

Thickness (mil)Thickness (mm)Thickness (inches)
10 mil0.25mm0.010 inches
12 mil0.30mm0.012 inches
20 mil0.50mm0.020 inches
30 mil0.76mm0.030 inches

Are Thicker Cards More Durable?

Yes. A thicker card is generally more resistant to bending, cracking, and everyday wear. For high touch retail or POS cards, 30 mil consistently offers the best long term durability. Thinner options like 10 mil and 12 mil trade some of that durability for lower cost and flexibility, which makes them a good fit for promotions and short term use.

Print and Material Compatibility

Card thickness affects which print options and materials you can use. The following options work across multiple thicknesses:

POS System Compatibility

Most POS systems are built for 30 mil PVC cards. If you plan to print barcodes or encode magnetic stripes, 30 mil is the industry standard for reliable performance. Plastek cards are compatible with most major POS systems. Just provide your POS card data specifications when you place your order.

How to Select the Right Plastic Card Thickness for Your Business

The best thickness depends on how the card will be used and how long it needs to last.

  1. Gift cards: 30 mil for a premium feel and dependable POS performance.
  2. Business cards: 12 to 20 mil for a substantial card that still mails easily.
  3. Loyalty and membership cards: 20 to 30 mil for repeated, long term use.
  4. Hotel key cards: 30 mil for durability and reliable encoding.
  5. Event passes and temporary badges: 10 to 20 mil for short term, cost sensitive runs.
