Card games are still among the most played games around the world. As cards have evolved from simple to elegant over time, brands are looking for ways to upgrade their card boxes with different customizations.

Knowing the dimensions of your playing cards is important for ordering the right-sized box, so the cards stay safe during shipping. To keep cards from bending and creasing, order custom playing card boxes cut to your exact deck size.

Read this blog to learn about the different types of card games, their dimensions and how you can customize their boxes.

History of Playing Card Games

Playing card games can be traced back to 9th-century China. Since then, their popularity has kept growing, and people keep creating new card games. Today, thousands of card games are played around the world. People love to play them with friends and family, and many families have a tradition of gifting card games at Christmas.

With more manufacturers in the market, the competition to keep customers has grown sharply. This is where knowing the accurate size of your cards and box customizations comes into play. Get to know the playing card sizes for different games and find the dimensions that fit your needs best.

How Many Cards Are in a Deck?

Whenever the conversation turns to playing card deck size, another question comes up: the number of cards. A standard deck has 52 cards, often with two jokers. Games like Tarot have 78 cards in a deck, while kids' decks vary by game.

If you are wondering about the dimensions of a deck of cards, a standard deck is around 0.75 inches thick. You can find the standard playing card sizes in inches, millimeters and centimeters below.

How Thickness Impacts the Dimensions of a Playing Card

Material thickness shapes the structure of the packaging, but it matters even more for the card itself, because it decides how durable the card is. Playing cards range from about 0.17 mm to 0.24 mm thick, while a full deck is around 0.67 to 0.95 inches thick.

Standard Thickness of Cards

The standard card thickness is around 0.0078 inches, which makes it easy to stack 52 cards or more without damage. You can choose a custom thickness for a distinctive feel. However, remember that a thicker card stock needs a deeper, sturdier box. The standard depth of a card game box is around 0.75 inches.

  • Card thickness: 0.0078 inches / 0.2 mm / 0.02 cm
  • Box depth: 0.75 inches / 19.05 mm / 1.9 cm

The Core of Playing Cards: Materials and Finishes

Whenever you hold a playing card, you feel its sturdiness and textured surface. That's no accident, but careful crafting. Playing cards are usually made from either 100% plastic or paper cardstock. For the box itself, see our guide to the best material for playing card boxes.

To make the surface more appealing, coatings are applied, such as:

  • Laminations (mostly matte)
  • Embossed or textured finishes
  • Liquid finishes (varnishes)

Get Customized Playing Cards to Enhance Visual Appeal

Customization helps a brand attract customers and stand apart from the competition. Many sellers offer new variations of the same game, and they rely heavily on customization to stand out.

Sometimes the customization depends on the deck dimensions, since smaller cards look better with cleaner designs. But you can choose any design regardless of size. You can customize your cards with OXO Packaging and get beautiful designs, bright colors and premium finishes.

Designs

Choosing a design may seem hard, but it's not that daunting. All you need is a bit of expert help to get your ideas on paper. Adult card designs tend to be simple yet elegant, while kids' cards can play on the fun side with animated characters and cute designs.

Colors

Choose the colors for your cards wisely. For kids' card games, you can use light and bright colors such as pastels or a touch of neon. For adult cards, darker and muted colors work well. Oracle and Tarot cards usually use dark shades for a mystical look.

Finishes

Adding finishes to your cards and boxes is a great way to keep customers hooked. You can use a gloss finish to make certain graphics shine, such as the moon. Similarly, a matte finish gives Tarot cards a more subdued look. On the box, a raised logo like those on our embossed boxes adds a tactile touch shoppers notice.
