Pokémon Card Dimensions: Size in MM and Inches
Pokémon cards are collected and played worldwide. Their size is standardized to ensure fair gameplay and easy storage. Understanding Pokémon card dimensions is important for collectors, competitive players, and sellers. Proper sizing helps with sleeves, binders, grading, and storage.
If you use the wrong size sleeve or case, your cards may bend or wear out. Knowing the exact measurements in millimeters and inches prevents damage and protects card value.
Standard Pokémon Card Dimensions
The official Pokémon card size follows the standard trading card format used by many TCG brands. A regular Pokémon card measures:
- 63 mm × 88 mm
- 2.5 inches × 3.5 inches
These measurements apply to most cards produced for the Pokémon Trading Card Game. This size is often called the “standard size” trading card format. It is the same size used by many popular card games. Because of this standardization, most sleeves and storage products labeled “standard size” will fit Pokémon cards perfectly.
Pokémon Card Dimensions in MM
In metric measurement, a standard Pokémon card is:
- 63 millimeters wide
- 88 millimeters tall
This measurement is precise and consistent across official print runs. Manufacturers maintain tight quality control to ensure uniformity. Even small differences in size could impact gameplay. Uniform card dimensions help prevent marked cards during competitive play. This ensures fairness in tournaments.
Pokémon Card Dimensions in Inches
In imperial measurement, Pokémon cards are:
- 2.5 inches wide
- 3.5 inches tall
This size makes them easy to shuffle and handle. The shape provides enough surface area for artwork, stats, and text without being too large. The thickness of a Pokémon card is typically around 0.3 mm, though this may vary slightly depending on print batch and card type.
Why Pokémon Card Dimensions Matter
Card size is important for several reasons. First, it ensures compatibility with sleeves and binders. Standard-size sleeves are designed specifically for 63 mm × 88 mm cards. Using smaller sleeves can damage edges. Using larger sleeves may cause slipping.
Second, card dimensions affect grading and resale value. Professional grading companies expect correct size and proportions. Cards that are trimmed or altered may lose value. Accurate dimensions confirm authenticity.
Third, tournament rules depend on uniform card size. Official events require standard dimensions. Any card outside regulation size may not be allowed in play.
Variations in Pokémon Card Sizes

While most Pokémon cards follow the standard size, there are exceptions. Promotional oversized cards exist. These are usually included in special collector boxes. Oversized cards are much larger than standard cards and are not legal for tournament play. They are designed for display purposes only.
Mini cards may also appear in special products. These are smaller than standard size and are not used in official gameplay. Despite these variations, the vast majority of playable Pokémon cards follow the 63 mm × 88 mm format.
Japanese vs. International Pokémon Cards
Japanese Pokémon cards use the same standard dimensions as English and other international versions. The artwork and layout may differ slightly. However, the physical size remains the same. This allows collectors to store both Japanese and international cards together without sizing issues.
Sleeves and Storage Recommendations
Since Pokémon card dimensions are 63 mm × 88 mm, look for sleeves labeled “standard size” or “66 mm × 91 mm.” Sleeves are slightly larger to allow easy insertion. Double sleeving is also common among competitive players. This involves placing the card in a tight inner sleeve first, then inside a standard outer sleeve.
Binders designed for standard trading cards are ideal. Top loaders and hard cases should also match the 2.5 × 3.5 inch size. Using correct accessories protects corners and edges from bending.
Printing and Custom Pokémon Cards
If you plan to print custom cards, you must follow official Pokémon card dimensions carefully. A design that is even a few millimeters off will not fit standard sleeves. It may also look inconsistent next to real cards. Maintaining the exact 63 mm × 88 mm size ensures compatibility with storage and gameplay tools.
Conclusion
Pokémon card dimensions are standardized at 63 mm × 88 mm or 2.5 inches × 3.5 inches. This size ensures compatibility with sleeves, binders, grading systems, and tournament play. Most official cards follow this exact format.
Oversized and mini cards exist but are not used in competitive gameplay. Knowing the correct dimensions helps protect your collection and ensures you use the right accessories. Whether you are a collector, seller, or player, understanding Pokémon card dimensions is essential.
