If you're a Pokémon fan, important collector, seller, or competitive player, understanding card Pokémon size is more important than you might think. Whether you're buying protective sleeves, grading your collection, printing custom proxies, or organizing binders, knowing the exact dimensions of Pokémon cards helps you protect and display them properly.

In this complete guide, we’ll cover standard Pokémon card dimensions, thickness, jumbo cards, mini cards, Japanese card sizes, and more.

What Is the Standard Pokémon Card Size?

The standard Pokémon card size is:

2.5 inches x 3.5 inches
or
63 mm x 88 mm

This size is also known as Standard Trading Card Game (TCG) size.

Pokémon cards share the same dimensions as:

• Magic: The Gathering cards
  
  

• Yu-Gi-Oh (Western editions differ slightly)
  
  

• Sports trading cards
  
  

Because Pokémon cards follow standard TCG sizing, most protective accessories are widely available and easy to find.

Pokémon Card Thickness

Besides length and width, thickness also matters.

The average Pokémon card thickness is approximately:

0.012 inches (0.30 mm)

This can vary slightly depending on:

• Printing era
  
  

• Manufacturer (Wizards of the Coast vs. modern prints)
  
  

• Holographic vs. non-holographic cards
  
  

• Promo cards
  
  

Holographic and full-art cards may feel slightly thicker due to foil layers, but the size remains the same.

Japanese Pokémon Card Size

A common question is whether Japanese Pokémon cards are a different size.

The answer is:

Japanese Pokémon cards are the same size as English Pokémon cards — 63 mm x 88 mm.

This makes it easy for collectors to use the same:

• Sleeves
  
  

• Toploaders
  
  

• Binders
  
  

• Storage boxes
  
  

The only difference is the language and sometimes print quality or card stock texture.

Jumbo Pokémon Card Size

Jumbo Pokémon cards are oversized promotional cards often included in special collections or box sets.

The most common jumbo card size is:

5.75 inches x 8 inches
(approximately 146 mm x 203 mm)

However, older jumbo cards were even larger. Over the years, The Pokémon Company adjusted jumbo card sizing to make them easier to store in binders.

Modern jumbo cards are more uniform and compatible with jumbo-specific binders.

Mini Pokémon Cards

Mini Pokémon cards are less common but do exist in certain products and promotional releases.

Mini cards are typically:

1.75 inches x 2.5 inches
(approximately 44 mm x 63 mm)

These are not tournament-legal and are usually novelty or collectible items.

Pokémon Card Size Compared to Other Cards

Here’s how Pokémon cards compare to other common trading cards:

This comparison helps when buying sleeves or storage products designed for different TCG brands.

Why Pokémon Card Size Matters

1. Protective Sleeves

Using the wrong sleeve size can:

• Bend corners
  
  

• Cause shifting inside the sleeve
  
  

• Reduce protection
  
  

For standard Pokémon cards, use Standard Size sleeves (63 x 88 mm).

2. Toploaders and Card Savers

If you're shipping or grading cards, proper sizing is crucial.

Standard toploader size:

• 3 x 4 inches (fits 2.5 x 3.5 cards)
  
  

For grading submissions, semi-rigid card holders designed for standard TCG size are recommended.

3. Binders and Storage

Standard 9-pocket binder pages are made for 2.5 x 3.5 inch cards. Oversized or mini cards will not fit properly in regular pages.

4. Custom Printing

If you're creating proxy cards or custom designs, setting your print file to:

• 63 mm x 88 mm
  
  

• 300 DPI resolution
  
  

will ensure accurate sizing.

Pokémon Card Corners and Edges

Pokémon cards have rounded corners, not sharp edges.

The corner radius is typically:
3 mm

This rounded design:

• Reduces wear and tear
  
  

• Prevents sharp damage
  
  

• Improves shuffling durability
  
  

When printing custom cards, remember to include rounded corners to match authentic cards.

Common Mistakes About Pokémon Card Size

Mistake 1: Assuming Yu-Gi-Oh Sleeves Fit

Yu-Gi-Oh cards are slightly smaller. Their sleeves will be too tight for Pokémon cards.

Mistake 2: Thinking All Jumbo Cards Are the Same Size

Older jumbo cards are larger than newer versions.

Mistake 3: Ignoring Thickness When Grading

Stack thickness can matter when sending multiple cards for grading.

Pokémon Card Size for Grading Services

Professional grading companies use precise measurements to confirm authenticity.

Cards that are:

• Too small
  
  

• Too large
  
  

• Incorrect thickness
  
  

may be flagged as counterfeit.

Counterfeit cards often differ slightly in:

• Width
  
  

• Height
  
  

• Card stock thickness
  
  

Measuring with digital calipers is common among serious collectors.

Evolution of Pokémon Card Dimensions

Interestingly, the standard card size has remained consistent since the Pokémon TCG launched in 1996. While artwork styles, borders, and textures have changed dramatically, the physical dimensions have stayed stable.

This consistency allows collectors to:

• Store vintage and modern cards together
  
  

• Use the same protective products
  
  

• Maintain uniform collections
