The Ultimate Guide to Credit Card Dimensions and Materials

From purchasing groceries to booking an exotic holiday, credit cards have become an integral part of our daily lives. With the rise of technology and modernization, credit cards have evolved from their basic plastic form, varying in sizes, shapes, and materials.

In this article, well take a closer look at the dimensions and materials of credit cards, providing you with all the necessary information to make an informed decision the next time you apply for a credit card. Part 1: Dimensions of a Credit Card

– Standard Size and Thickness

Credit cards usually measure 85.60 mm x 53.98 mm, or 3.375 inches by 2.125 inches in length and width, respectively.

The thickness of credit cards usually range from 0.76 mm to 1.24 mm, or 0.03 inches to 0.049 inches. This size and thickness are commonly referred to as CR80 or credit card size.

Non-Standard Sizes and Materials

In addition to the standard size and thickness, credit cards can also come in non-standard sizes and materials. Parking and store cards, for instance, can come in larger or smaller sizes compared to the standard CR80 size.

Some metal cards are thicker and heavier, measuring up to 1.5 mm or more. PVC cards, on the other hand, are thinner and more flexible than metal cards.

Part 2: Materials used in Credit Cards

– History of Credit Card Materials

Credit cards have gone through numerous changes over the years, ranging from celluloid plastic to fiber. In the early days of credit cards, celluloid plastic was the primary material used.

However, it was later replaced by a more durable and flexible material, polyvinyl chloride, or PVC. The first PVC card was issued in the 1960s and gained popularity due to its resistance to wear and tear and increased flexibility.

Benefits and Drawbacks of Metals versus PVC

While PVC cards remain the most popular credit card material, metal cards have gained popularity over the years. Metal cards are usually made from stainless steel or titanium, making them highly durable and resistant to scratches and damage.

They are also heavier and thicker than PVC cards, giving them a premium feel. However, these factors also make metal cards less flexible and more difficult to laminate, compared to PVC cards.

PVC cards, on the other hand, are lightweight, flexible, and easy to laminate. They also come in a variety of colors and designs.


In conclusion, knowing the dimensions and materials used in credit cards can go a long way in helping you make informed decisions and choosing the right credit card that best suits your needs. Credit card dimensions usually vary based on the type of card, but the standard size is the CR80 size.

Credit card materials have also evolved over the years, with PVC being the most popular material, followed by metals such as stainless steel and titanium. Whatever your choice of material is, credit cards are an essential tool for modern-day living, granting you the purchasing power and financial flexibility necessary to navigate in todays evolving financial landscape.


Part 3: Credit Card Evolution

– Early Credit Card History

Before credit cards, people used charge coins, which were made of metal and carried by customers as a charge account identifier. These soon evolved into Charga-Plates, which were made of paper and plastic and issued by merchants to their customers.

Charga-Plates were an early form of credit cards that allowed customers to purchase items on credit and pay for them later. In 1949, the Air Travel Card (now known as the Universal Air Travel Plan), was introduced.

It was designed for frequent travelers looking for a more convenient way to pay for their airfare. A year later, the Diners Club Card was issued, ushering in the era of modern-day credit cards.

The Diners Club Card was the first card to be accepted by a broad range of merchants, unlike the Air Travel Card, which was limited to airfare purchases. In 1958, American Express introduced the first charge card that allowed customers to pay the balance in full each month.

This was followed by the Carte Blanche Card in 1959, which allowed customers to make charges at a wide range of merchants, similar to the Diners Club Card. – Modern Credit Card Features

Modern credit cards have come a long way from their early counterparts.

Apart from the bank or business name, the authorized user name, card number, and expiration date, modern credit cards come with various features that add convenience and security to their owners. These features include online bill payment, account alerts, and mobile apps that allow customers to view statements, monitor their credit score and track purchases at their fingertips.

Part 4: Miscellaneous Information

– Rounded Corners on Credit Cards

Credit cards usually have rounded corners. This is to ensure that the cards don’t get jammed in card readers and to make them easier to carry in wallets and purses.

Card makers ensure that the corners are uniform and smooth to avoid any jagged edges that may cause discomfort or irritation when carrying the card. – Length of Credit Card Numbers

Credit card numbers usually contain 16 digits, which are divided into four groups of four digits each.

However, some credit cards can have shorter or longer numbers, depending on the issuer and the card type. For instance, some American Express cards have 15 digits, while some newer Visa and Mastercard cards have 19 digits.

Card issuers use these variations in length to help differentiate between different card types and ensure that the cardholder can identify which card they are using, even without looking at the card itself.


Credit cards have come a long way from their early beginnings as charge coins and Charga-Plates. Today, modern credit cards offer numerous features that make shopping and financial transactions easier and more secure.

From rounded corners to variations in credit card numbers, there is a lot that goes into making a credit card. But one thing remains consistent: the power and convenience that credit cards offer as a means of payment in today’s modern world.

In conclusion, credit cards have undergone significant changes throughout history, from early charge coins to modern-day credit cards with features that make transactions easier and more secure. Understanding credit card dimensions and materials, as well as the evolution of credit cards, can help you make informed decisions when choosing a card that suits your needs.
