What Are the Dimensions of a Playing Card? A Complete Size Guide

Introduction to Playing Card Dimensions

Have you ever picked up a deck of cards and thought about how they fit so perfectly in your hands? Most of us have grown up playing card games without ever thinking about the size of those cards. Playing cards are so easy to play with. They shuffle smoothly, stack neatly, and fit perfectly into their boxes. 

The size of playing cards plays a bigger role in their usability than most people think. Card size affects comfort, shuffling, visibility, storage, and even how their packaging is designed. Once you start paying attention to these things, you’ll start to see how much thought went into something that feels so simple.

In this blog, we’ll break down playing card dimensions, their importance, and their impact. 

Why Playing Card Size Matters

Card games are meant to feel smooth and hassle-free. When the size of the cards is right, players focus on the game, not the cards themselves. But the moment a deck of cards feels uncomfortable to play with, their gameplay slows down.

The size of your cards affects the player’s grip. It affects how easily cards fan out in your hand. It affects how quickly you can shuffle without bending corners. These things may seem small and minuscule, but they shape up the entire gaming experience.

For businesses, on the other hand, card sizes matter in a completely different way. Things like printing layouts, card box design, storage, and shipping all depend on having accurate dimensions of a playing card. If your measurements aren’t precise to the mark, then it can lead to loose card packaging, damaged product, or wasted space. 

How Card Dimensions Affect Handling, Shuffling, and Gameplay

The size of a card deck really affects shuffling and handling. When your cards are sized correctly, they slide smoothly during shuffling without their corners getting caught or sides bending. 

If the cards are sized properly, they have a consistent shuffle. This helps players fan their cards easily, throw quick looks at the values, and stack the cards up smoothly between each game.

Brief Overview of Standard vs Custom Card Sizes

Most decks follow a standard playing card size that fits the average hand perfectly. Custom card sizes are also an option that exists mostly for branding purposes, as educational tools, promotional decks, as well as novelty products. They don’t have the same smoothness in shuffling and handling and need careful planning to ensure usability and proper packaging.

What Is the Standard Playing Card Size?

If you heard anyone talking about standard card sizes, they were probably talking about the most widely accepted card format used in everyday play.

The size of a standard playing card is 2.5 inches wide and 3.5 inches tall. The set size is widely used in games like poker, blackjack, or any other traditional card game.

Official Standard Playing Card Dimensions

In imperial measurements, the playing card size is:

• Width: 2.5 inches
• Height: 3.5 inches

In metric terms, the dimensions of a playing card are:

• Width: 63.5 millimeters
• Height: 88.9 millimeters

Metric vs Imperial Measurements

Both metric and imperial card sizes are the same; the only difference is their measuring unit. These units are inches and millimeters. Inches are commonly used in the United States, while millimeters are more common internationally. 

Thickness and Card Stock Considerations

The thickness of the cards is just as important as their width and height. Most standard cards are about 0.3 millimeters thick per card. This allows a full deck to stack neatly while still feeling sturdy.

Dimensions of a Playing Card (In Inches & Millimeters)

Let’s discuss the exact measurements used in a playing card set, in both inches and millimeters.

Standard Playing Card Size Chart

The most common trading card dimensions are:

• 2.5 inches by 3.5 inches
• 63.5 mm by 88.9 mm

This size has become the industry standard because it balances comfort, visibility, and ease of use.

Width, Height, and Corner Radius

We’ve already talked about the width and height; let’s move onto another element that’s equally important. You might have noticed that there are some cards with a rounded corner radius. Rounded corners reduce wear, prevent sharp edges, and make cards easier to shuffle. Cards with poor corner rounding frat, bend, or peel much faster over time.

Why These Dimensions Became the Industry Standard

The size of a playing card has been the same for years. This is because this set of measurements fits most hands easily, allows symbols to be printed clearly on cards, and makes handling and card shuffling smooth. Over time, players grew used to this size, and it became the industry standard.

Poker Card Size Explained

The term “poker card size” is commonly used to describe standard playing cards found in most decks. These cards are the same as any other deck of cards. 

Poker Card Size vs Standard Playing Cards

In most cases, poker-size cards follow the same 2.5 by 3.5 inch format. This means the size of both card sets are typically the same.

Why Poker-Size Cards Are Used in Casinos

Casinos host multiple games at the same time. All these games need to be smooth and efficient for them to be able to start the next bet just as quickly. This is why cards at a casino need to be easy to read across the table, quick to shuffle, and simple to handle during long sessions. Poker-size cards check all of those boxes, which is the reason why they are the preferred choice for such professional environments.

Best Games for Poker-Sized Cards

There are a lot of games you can play with this type of deck. You play games like: 

• Texas Hold’em
• Omaha
• Five Card Draw
• Seven Card Stud
• Razz
• Pineapple Poker

These are just a few options. You can play many more!

Bridge Card Size vs Poker Card Size

Bridge cards are another type of playing cards. These are slightly different from poker or standard playing cards. Bridge-size cards are designed with a different type of gameplay in mind. They offer a slimmer feel that works better for games where players hold many cards at once.

Key Differences in Width and Height

Bridge cards are narrower than poker cards. They usually measure 2.25 inches wide and 3.5 inches tall. The height stays the same, but the reduced width changes how the cards sit in the players hand.

Which Size Is Better for Small Hands

Do you have smaller than average hands? Well then you might justfind bridge cards easier to handle than the standard card deck. The narrower width makes it simpler to fan cards and keep them organized during longer games.

Popular Games That Use Bridge-Size Cards

• Bridge
• Hearts
• Spades
• Euchre
• Oh Hell!

GSM and Paper Stock Options

The paper the cards printed on is also very important. Higher GSM usually means heavier, more durable cards that hold up better over time.

Coated vs Uncoated Finishes

There is one big difference between these two: Coated cards slide more easily and resist moisture. Uncoated cards have a softer feel but wear faster with frequent use.
