Credit cards have become an essential part of our daily lives, allowing us to make purchases conveniently and securely. But have you ever wondered what size a credit card actually is? In this article, we will explore the standard dimensions of a credit card and delve into some additional details related to its size.

The Standard Size of a Credit Card

Dimensions: The standard size of a credit card is 3.375 inches (85.6 mm) in width and 2.125 inches (53.98 mm) in height. These dimensions are commonly used across the world for most credit cards, including those issued by major financial institutions.

Thickness: In addition to the dimensions mentioned above, credit cards typically have a thickness of 0.030 inches (0.76 mm). This thickness allows them to fit comfortably in wallets and cardholders while maintaining durability.

Variations in Size

While the dimensions mentioned above represent the standard size of a credit card, it is important to note that there can be slight variations in size among different card issuers and regions. Some cards may be slightly thicker or thinner, and there may be minor differences in width and height. However, these variations are generally minimal and do not significantly impact the card’s functionality or compatibility with card readers.

Materials Used

Plastic: The majority of credit cards are made from plastic, specifically polyvinyl chloride (PVC). PVC is a durable and lightweight material that allows for easy production and customization of credit cards.

Metal: In recent years, metal credit cards have gained popularity due to their premium feel and enhanced security features. These cards are typically made from stainless steel or other metals and are slightly heavier and thicker than their plastic counterparts.

Additional Features and Considerations

Apart from the standard dimensions, credit cards may include additional features and considerations that can impact their size:

Embossing: Some credit cards have raised numbers and letters on the front, known as embossing. This feature adds a tactile element to the card but also increases its thickness slightly.

Chip and PIN: With the widespread adoption of chip and PIN technology, many credit cards now have an embedded microchip. This chip adds a small bump to the surface of the card but does not significantly affect its overall size.

Contactless Technology: Contactless payment technology, such as Near Field Communication (NFC), allows for quick and convenient payments by simply tapping the card on a compatible reader. Cards with contactless technology may have a small symbol (such as a Wi-Fi-like icon) indicating their compatibility.


In summary, the standard size of a credit card is 3.375 inches in width, 2.125 inches in height, and 0.030 inches in thickness. While there may be slight variations in size among different card issuers and regions, these differences are generally minimal. Credit cards are typically made from plastic or metal, with additional features like embossing, microchips, and contactless technology that may slightly impact their size.
