Playing cards have been around for centuries, delighting people across cultures with their versatility for games, magic tricks, and collecting. But when it comes to design, printing, and gameplay, one of the most important yet overlooked aspects is the standard playing card size. Whether you’re a game designer, card collector, or just curious, understanding the standard dimensions and their variations can help you choose or create the perfect deck.

What Is the Standard Playing Card Size?

The most commonly used standard playing card size is:

88 mm × 63 mm (8.8 cm × 6.3 cm)

Or in inches: 3.5 in × 2.5 in

This format is known as the poker size and is widely adopted across the world for standard card games, poker, blackjack, and collectible decks. These dimensions strike the perfect balance between comfort, portability, and usability, making them ideal for both casual and professional use.

Why Card Size Matters

The dimensions of a playing card affect:

• How it feels in hand

• Shuffling ease

• Readability of the design

• Storage and packaging

• Game dynamics

A card that’s too large can be cumbersome, while a card that’s too small can make shuffling and dealing a hassle. That’s why industry-standard sizes exist—to offer a tried-and-tested solution that works in most use cases.

Popular Playing Card Sizes and Their Use Cases

Standard Playing Card Size for Printing and Design

If you’re designing your own card game or promotional deck, it’s crucial to follow standard printing specifications. Most print companies require:

• 3 mm bleed on all sides

• 300 DPI resolution for crisp prints

• CMYK color format for accurate color output

Final print size with bleed for poker cards:

• 94 mm × 69 mm (9.4 cm × 6.9 cm)

Use professional tools like Adobe Illustrator, Photoshop, or Canva with preset templates to maintain alignment and clarity.

Materials and Finish Affect Handling

Beyond size, card stock and finish affect the user experience. Standard poker cards are often printed on:

• 300-350 GSM card stock

• With a linen or smooth finish

• And UV coating or plastic lamination for durability

These additions enhance:

• Shuffling performance

• Resistance to moisture and wear

• Overall feel in the hand

  This comfortably fits 54 cards, including jokers, and is designed for compact storage and retail presentation.
