Pokémon Card Dimensions: Size, Height & Width 2026
A standard Pokémon card measures 2.5 inches (6.35 cm) wide by 3.5 inches (8.89 cm) tall the exact same size as every other standard trading card in the world, from Magic: The Gathering to sports cards. That is roughly the width of two fingers side by side and the height of a standard index card cut in half.
Whether you’re buying card sleeves for your collection, spotting a fake card at a trade, or designing custom Pokémon-style card artwork, knowing exact Pokémon card dimensions gives you an instant reference point.

What Are the Standard Pokémon Card Dimensions?
A standard Pokémon card measures exactly 2.5 × 3.5 inches (6.35 × 8.89 cm). That is the same size as a standard business card in portrait orientation — except a business card is 3.5 × 2 inches (8.89 × 5.08 cm) in landscape, meaning a Pokémon card is just slightly taller. Place two standard credit cards side by side — that width comes very close to 3.5 inches (8.89 cm), nearly matching the card’s height.
Hold a Pokémon card against your palm. For most adults, the card width of 2.5 inches (6.35 cm) matches the width of three fingers held together. The card height of 3.5 inches (8.89 cm) runs from just below your wrist crease to about the middle of your palm. These proportions make every card feel perfectly balanced in your hand.
| Measurement | Inches | Centimeters | Millimeters | Feet |

| Width | 2.5 in | 6.35 cm | 63.5 mm | 0.208 ft |
| Height | 3.5 in | 8.89 cm | 88.9 mm | 0.292 ft |

| Card area | 8.75 sq in | 56.45 sq cm | 5,645 sq mm | — |
The corner radius of 3 mm (0.118 in) is one of the most important measurements for collectors. Cards without this precise rounded corner are immediately suspicious. Fake cards often have corners that are too sharp or too rounded compared to this exact spec.
Variations in Pokémon Card Dimensions
Not every Pokémon card is the same size. The standard international card at 2.5 × 3.5 inches (6.35 × 8.89 cm) is the most common format. However, Pokémon has produced several special formats over the years that differ in size.
Jumbo cards measure 4.5 × 6.25 inches (11.43 × 15.88 cm) exactly 1.8 times larger than a standard card in both dimensions. You receive these oversized cards in special promotional sets and collector boxes. Jumbo cards do not fit standard sleeves or binders and require dedicated oversized storage pages.
Mini cards appeared in early Japanese sets and some promotional products. They measure approximately 1.75 × 2.5 inches (4.45 × 6.35 cm) exactly half the height of a standard card. These tiny cards are novelty items and collector’s pieces rather than playable game cards.
| Card Type | Width | Height | Use |
|---|---|---|---|
| Japanese Standard | 2.48 in / 6.3 cm | 3.46 in / 8.8 cm | Japan market, older sets |
| International Standard | 2.5 in / 6.35 cm | 3.5 in / 8.89 cm | USA, EU, global play |
| Jumbo / Oversized | 4.5 in / 11.43 cm | 6.25 in / 15.88 cm | Promotions, display |
| Mini Card | 1.75 in / 4.45 cm | 2.5 in / 6.35 cm | Novelty, Japanese promos |
Pokémon Card Thickness
A standard Pokémon card measures 0.035 inches (0.89 mm) thick. That is just under 1 millimeter about the same thickness as a single sheet of heavy cardstock paper. You can feel the difference between a genuine card and a fake card just by its thickness.
A stack of 100 standard Pokémon cards measures approximately 3.5 inches (8.89 cm) tall exactly the same as the height of one individual card lying flat. This fact makes stacking and storage math very simple for collectors. A standard 9-pocket binder page holds 9 cards and adds about 0.315 inches (8 mm) of thickness per page when full.
Foil cards and full-art cards sometimes measure slightly thicker due to their special printing layers. A holo foil card can reach up to 0.040 inches (1.02 mm) thick — about 0.005 inches (0.127 mm) thicker than a standard non-holo card. Grading companies like PSA and Beckett measure card thickness as part of their authentication and grading process.
Comparing Pokémon Card Dimensions to Other Trading Cards
Pokémon cards share their 2.5 × 3.5 inch (6.35 × 8.89 cm) dimensions with the entire standard trading card industry. This is not a coincidence — The Pokémon Company designed their cards to match the universal trading card standard so collectors could use the same sleeves, binders, and storage products already on the market.
Here is how Pokémon cards compare to other popular trading cards:
| Card Type | Width | Height | Same Size as Pokémon? |
|---|---|---|---|
| Pokémon (International) | 2.5 in / 6.35 cm | 3.5 in / 8.89 cm | ✅ Baseline |
| Magic: The Gathering | 2.5 in / 6.35 cm | 3.5 in / 8.89 cm | ✅ Identical |
| Yu-Gi-Oh! | 2.25 in / 5.72 cm | 3.25 in / 8.26 cm | ❌ Smaller |
| Sports Cards (standard) | 2.5 in / 6.35 cm | 3.5 in / 8.89 cm | ✅ Identical |
| One Piece TCG | 2.5 in / 6.35 cm | 3.5 in / 8.89 cm | ✅ Identical |
| Disney Lorcana | 2.5 in / 6.35 cm | 3.5 in / 8.89 cm | ✅ Identical |
| Flesh and Blood | 2.5 in / 6.35 cm | 3.5 in / 8.89 cm | ✅ Identical |
Yu-Gi-Oh! cards are noticeably smaller at 2.25 × 3.25 inches (5.72 × 8.26 cm). A standard Pokémon sleeve does not fit a Yu-Gi-Oh! card correctly the card slides around inside. Always buy the correct sleeve size for each game you collect or play.
Japanese vs USA/International Pokémon Card Sizes
Japanese Pokémon cards are very slightly smaller than international cards. A Japanese card measures 2.48 × 3.46 inches (6.3 × 8.8 cm). The international card measures 2.5 × 3.5 inches (6.35 × 8.89 cm). The difference is just 0.02 inches (0.5 mm) in width and 0.04 inches (1 mm) in height.
The card can shift inside the sleeve during shuffling, which causes wear on the corners. Dedicated Japanese card sleeves — sold in Japan and through import retailers — fit Japanese cards exactly at 2.48 × 3.46 inches (6.3 × 8.8 cm).
| Feature | Japanese Cards | International Cards |
|---|---|---|
| Width | 2.48 in / 6.3 cm | 2.5 in / 6.35 cm |
| Height | 3.46 in / 8.8 cm | 3.5 in / 8.89 cm |
| Width difference | — | +0.02 in / +0.5 mm larger |
| Height difference | — | +0.04 in / +1 mm larger |
| Correct sleeve | Japanese-size sleeves | Standard 2.5 × 3.5 in sleeves |
| Fits international binders? | Loose fit | Perfect fit |
Japanese cards also use slightly different cardstock. The paper feels slightly thinner and more flexible than international cards. This difference is noticeable when you hold both versions of the same card simultaneously a detail that experienced collectors and graders use to verify card origin.
Protecting Your Cards: Sleeves, Top Loaders, and Storage Based on Dimensions
Choosing the right protection starts with knowing your card dimensions exactly. The wrong sleeve size causes edge wear, corner damage, and moisture exposure all of which reduce your card’s grade and value.
Card sleeves for standard Pokémon cards measure 2.625 × 3.75 inches (6.67 × 9.53 cm) — slightly larger than the card itself to allow easy insertion. Popular sleeve brands like Dragon Shield, Ultra PRO, and KMC all manufacture to this standard inner dimension.
Top loaders the rigid plastic card holders measure 3 × 4 inches (7.62 × 10.16 cm) for standard cards. This gives 0.5 inches (12.7 mm) of clearance around the card on all sides. Collectors place a penny sleeve on the card first, then slide the sleeved card into the top loader.
Binder pages use a 9-pocket format where each pocket measures approximately 2.75 × 3.75 inches (6.99 × 9.53 cm). Nine standard Pokémon cards fill one page perfectly. A standard 3-ring binder holds 20 pages, storing 180 cards per binder.
| Protection Type | Inner Width | Inner Height | Best For |
|---|---|---|---|
| Penny sleeve | 2.625 in / 6.67 cm | 3.75 in / 9.53 cm | Budget protection, bulk cards |
| Perfect fit sleeve | 2.56 in / 6.5 cm | 3.56 in / 9.04 cm | Snug fit, graded submissions |
| Standard sleeve | 2.625 in / 6.67 cm | 3.75 in / 9.53 cm | Everyday play and storage |
| Top loader | 3.0 in / 7.62 cm | 4.0 in / 10.16 cm | Single valuable cards |
| Magnetic case (35pt) | 2.625 in / 6.67 cm | 3.75 in / 9.53 cm | Display and high-value singles |
| 9-pocket binder page | 2.75 in / 6.99 cm | 3.75 in / 9.53 cm | Collection organization |
PSA grading submission requires cards in a penny sleeve only no top loader, no hard case. PSA and Beckett measure card dimensions, thickness, and corner radius as part of their grading criteria.
Spotting Fake Pokémon Cards Through Dimensions and Size Checks
Fake Pokémon cards almost always fail basic dimension tests. A real card measures exactly 2.5 × 3.5 inches (6.35 × 8.89 cm) with a 3 mm (0.118 in) corner radius. Most fakes deviate from at least one of these measurements by a detectable margin.
Check the width and height first. Use a ruler or a genuine card as a reference. Fake cards commonly measure 2.4 to 2.6 inches (6.1 to 6.6 cm) wide slightly off in either direction. A card that is even 0.05 inches (1.27 mm) too wide or narrow fails the dimension test immediately.
Check the thickness next. A genuine card measures 0.035 inches (0.89 mm) thick. Fake cards frequently measure 0.025 to 0.030 inches (0.64 to 0.76 mm) noticeably thinner and flimsy when you flex them. Extremely thick fakes come in at 0.045 to 0.050 inches (1.14 to 1.27 mm) — noticeably stiff and rigid compared to genuine cards.
Check the corner radius last. Genuine cards have a perfectly consistent 3 mm (0.118 in) rounded corner on all four corners. Fake cards often have uneven corners — one corner may be sharper while another is more rounded.
| Measurement | Genuine Card | Common Fake | Red Flag Threshold |
|---|---|---|---|
| Width | 2.5 in / 63.5 mm | 2.4–2.6 in | More than 1 mm off |
| Height | 3.5 in / 88.9 mm | 3.4–3.6 in | More than 1 mm off |
| Thickness | 0.035 in / 0.89 mm | 0.025–0.050 in | More than 0.2 mm off |
| Corner radius | 3 mm / 0.118 in | 2–5 mm | Uneven or noticeably different |
Experienced collectors call this the “feel and measure” test. If a card feels wrong in your hand too light, too stiff, or slightly too small measure it immediately. Your instincts after handling thousands of genuine cards become calibrated to the exact 2.5 × 3.5 inch (6.35 × 8.89 cm) standard.

Frequently Asked Questions
What are the exact dimensions of a Pokémon card?
A standard international Pokémon card measures exactly 2.5 inches (6.35 cm) wide by 3.5 inches (8.89 cm) tall. The thickness is 0.035 inches (0.89 mm) and the corner radius is 3 mm (0.118 in). These dimensions match Magic: The Gathering, standard sports cards, and most other major trading card games.
Are Japanese Pokémon cards a different size than international cards?
Yes — Japanese Pokémon cards measure 2.48 × 3.46 inches (6.3 × 8.8 cm), making them slightly smaller than international cards at 2.5 × 3.5 inches (6.35 × 8.89 cm). The difference is just 0.02 inches (0.5 mm) in width and 0.04 inches (1 mm) in height. This small gap means standard international sleeves fit Japanese cards loosely.
What size sleeve fits a Pokémon card?
Standard card sleeves with an inner dimension of 2.625 × 3.75 inches (6.67 × 9.53 cm) fit Pokémon cards perfectly. For a tighter, more protective fit before grading, use “perfect fit” sleeves measuring 2.56 × 3.56 inches (6.5 × 9.04 cm). Brands like Dragon Shield, Ultra PRO, and KMC all produce sleeves in this standard size.
How do I know if a Pokémon card is fake by its size?
Measure the card with a ruler. A genuine card is exactly 2.5 × 3.5 inches (63.5 × 88.9 mm). Any deviation of more than 1 mm in either dimension is a red flag. Also check thickness — genuine cards measure 0.035 inches (0.89 mm) thick. Cards thinner than 0.030 inches (0.76 mm) or thicker than 0.040 inches (1.02 mm) are almost certainly fake.
What size are Jumbo Pokémon cards?
Jumbo Pokémon cards measure 4.5 × 6.25 inches (11.43 × 15.88 cm) exactly 1.8 times larger than a standard card. You cannot fit jumbo cards in standard sleeves, top loaders, or binder pages. They require dedicated oversized storage products and are not legal for tournament play.
How thick is a stack of 100 Pokémon cards?
A stack of 100 standard Pokémon cards measures approximately 3.5 inches (8.89 cm) tall the same as the height of one card lying flat. This makes storage calculations simple: every 100 cards takes up exactly one card-height of vertical space. A full 9-pocket binder page holding 9 cards adds about 0.315 inches (8 mm) of thickness when full.
Conclusion
Pokémon card dimensions appear constantly in your daily life through card sleeves, binder pages, top loaders, and grading submissions. This precise measurement exactly 2.5 × 3.5 inches (6.35 × 8.89 cm) with a 0.035-inch (0.89 mm) thickness equals the size of a standard business card in portrait format, or about the same dimensions as two credit cards stacked side by side.
Now that you understand Pokémon card dimensions across every format and use case, you can choose the perfect sleeve or top loader for any card, spot fakes instantly using a ruler and the correct measurements, store and protect your collection with total confidence, and navigate the size difference between Japanese and international cards. Use these exact measurements whenever you’re buying protection supplies, authenticating cards at a trade, or submitting cards for grading for better accuracy and completely confident collecting decisions.
