Pokémon card sizes and sleeve compatibility

A standard Pokémon card is 63 x 88 mm, or 2.5 x 3.5 inches. That is the card size sleeve, binder and toploader makers build around, but each accessory is quoted by the card it fits, and its own outside measurements are larger. The figures below are each maker's own, set side by side.

Standard Pokémon card dimensions

The 63 x 88 mm figure comes from accessory makers' published specs, read on 17 October 2026. Dragon Shield's size guide gives its standard size as 63 x 88 mm (2½ x 3½ in) and names Pokémon among the games it fits. Ultra PRO writes the same card as 2.5 x 3.5 inches, converts that to 63.5 x 88.9 mm, and names Pokémon on its Eclipse sleeve and Platinum Series page listings. The gap between the two is under a millimetre in total (0.5 mm across, 0.9 mm down), which is rounding of one card size rather than two sizes.

None of the pokemon.com product pages checked for this guide gives a card dimension. They list what is in each box and stop there. So treat 63 x 88 mm as the nominal size that accessories are designed to, not as an official Pokémon specification.

Thickness is quoted separately, in points (pt). Ultra PRO rates its regular 3 x 4 inch toploader and its standard ONE-TOUCH magnetic holder for standard cards up to 35pt. None of the sources used here gives a thickness for a Pokémon card itself, so 35pt is the ceiling a holder is built for, not a measurement of the card.

These are nominal dimensions for a card as printed. A card that has been trimmed or miscut, or one that is bent or bowed, will not match them, and a sleeve or toploader sized for a flat, full-size card may catch on it. If a card measures well off 63 x 88 mm, check it against another copy from the same set before you rely on it. How to spot fake Pokémon cards covers the other checks to make.

The words "Japanese size" on a sleeve box describe a card format, not where a card was printed. Dragon Shield lists its Japanese size as 59 x 86 mm cards, for Yu-Gi-Oh, Cardfight Vanguard, Weiss Schwarz and other Japanese-format games. Pokémon sits under its standard size, and the size guide does not split Pokémon by language. Sleeves made for 59 x 86 mm cards are cut for a smaller card than a 63 x 88 mm one, so they will not take it.

Choose a sleeve that fits

Sleeve makers quote two different numbers, and it helps to know which one you are reading. Gamegenic gives both: its Prime and Matte Prime sleeves are 66 x 91 mm and take a card up to 64 x 89 mm. Dragon Shield quotes only the card size, 63 x 88 mm, under the name standard size. Ultra PRO says its Eclipse Deck Protector sleeves are designed to fit standard cards up to 2.5 x 3.5 inches, Pokémon included.

Those are the same class of sleeve described in different ways. The 66 x 91 mm figure is the outside of the sleeve, so comparing it with a 63 x 88 mm card makes the sleeve look oversized when it is not. When a box gives one number only, check whether it says sleeve size or card size before you compare it with anything.

The other choice is between a penny sleeve and a deck sleeve. Ultra PRO Penny Sleeves are soft 2.5 x 3.5 inch sleeves, and they are the sleeve both toploader makers below name for their regular holders. Deck sleeves such as Dragon Shield Matte (120 µm) or Gamegenic Prime are made for shuffling and play. If you want a card to stay sleeved inside a hard holder, Ultra PRO lists its ONE-TOUCH X for a 35pt standard card inside a protective sleeve, up to Platinum Sleeve Size. The page names no other sleeve, so treat any deck sleeve in it as untested.

The table puts each accessory next to the card size it is built for, in the maker's own words. The last column says that each entry is the maker's stated spec, not a fit test. Our sleeves page will state the same figures for every sleeve we will stock.

Inner sleeves and double sleeves

Double sleeving means a close-fitting inner sleeve on the card, then a deck sleeve over the top. Gamegenic's figures show the chain: a card up to 63 x 88 mm goes into a 64 x 89 mm inner sleeve, and its Prime sleeves take a card up to 64 x 89 mm inside a 66 x 91 mm outer. Gamegenic says its inner sleeves protect cards from dust, dirt and other damage such as frequent shuffling. Dragon Shield sells inners as Perfect Fit, in a 100 µm Thick version and a 50 µm sealable version, and says dust will have a hard time getting into the sealable one.

Whether a given inner fits a given outer is a question about two products, not a standard. Each maker states its own pairing only. Dragon Shield says Perfect Fit Thick sleeves fit smoothly inside regular Dragon Shield sleeves, and Ultra PRO says PRO-Fit fits inside a standard size Deck Protector sleeve, which is its own range. Where you mix brands, compare the inner sleeve's stated sleeve size with the outer sleeve's stated card size, and treat any pairing no maker states as untested.

Double sleeving also adds thickness. Dragon Shield says cards double sleeved with its sealable Perfect Fits come out slightly thicker than with the normal ones, and that whole decks become noticeably thicker. That matters once the card goes into a 35pt holder or a 9-pocket page. The storage guide walks through which cards suit a double sleeve and which suit a penny sleeve and a toploader.

Binder pockets and toploader fit

A sleeve, a binder pocket and a toploader all have to fit the same card, so the three numbers need checking together. A pocket or a toploader has to take the card plus its sleeve, and a toploader has a thickness limit as well.

Vault X states a 68 x 97 mm internal pocket for its 9-Pocket Exo-Tec Zip Binder and says it is for single-sleeved and double-sleeved cards. That is 2 mm wider and 6 mm taller than Gamegenic's 66 x 91 mm outer sleeve. Ultra PRO's Platinum Series 9-Pocket Pages are described for 2.5 x 3.5 inch cards and say nothing either way about sleeves. Where a binder quotes only the card size, its maker has not told you whether a sleeved card fits. Our binders page will give the pocket size for every binder we will stock.

Toploaders are named by their outside size. Ultra PRO's regular toploader is 3 x 4 inches and is sized for 2.5 x 3.5 inch cards up to 35pt. BCW's standard 3 x 4 holder is the one that publishes an interior, 2 3/4 x 3 7/8 inches inside an exterior of 3 x 4 1/16 inches. BCW's page disagrees with itself on thickness: the feature bullets say up to 35pt, while the description and the FAQ say 20pt. Until BCW settles it, the safer reading is 20pt.

Both toploader makers name the penny sleeve. Ultra PRO lists penny sleeves as a compatible product for its regular toploader, and BCW says its holder takes standard cards in penny sleeves. Neither page says anything about deck sleeves. For a card that stays sleeved, Ultra PRO's ONE-TOUCH X is a magnetic holder with a larger cavity, listed for a 35pt card inside a protective sleeve, up to Platinum Sleeve Size. It does not name any deck sleeve.

Thicker items have their own holders. Ultra PRO sells 3 x 4 inch toploaders rated at 55pt, 120pt, 130pt, 180pt and 260pt. Our toploaders page will state the thickness rating on every holder.

Jumbo, metal and other nonstandard cards

Pokémon's own term is "oversize card", and BCW describes them as cards included in themed box sets. The Celebrations Prime Collection included four oversize cards, among them Dragapult Prime and Mimikyu δ, plus an oversize card binder. The Red & Blue Collection Pikachu-EX included one oversize Pikachu-EX card. Neither pokemon.com page gives the size of those cards.

There is no single jumbo size. BCW's blog post of 14 April 2023 gives two main sizes, 6 x 8 inches before 2020 and 5.75 x 8 inches after, with a few cards at 6 x 9 inches. BCW suggests a 6 x 9 inch size even though it is a little tall, because a 6 x 8 inch one leaves the top edge exposed.

Ultra PRO's 5 x 7 inch toploader (127 x 177.8 mm) is smaller than any of those sizes, so it will not take a jumbo card. For a binder, BCW points to comic book pages, which it says hold these cards bare, sleeved or in a toploader. Measure the card itself before you buy anything sold for jumbo cards.

Metal cards are a separate format again. The Celebrations Ultra-Premium Collection included two commemorative metal cards, Base Set Pikachu and Base Set Charizard, which pokemon.com describes as made of solid metal. The page gives no dimensions or thickness, and no accessory maker cited here rates a holder for them. Measure the card's thickness and check it against a holder's pt rating before you buy one, or keep the card in the packaging it came in.

Once you know a card is standard size, the next step is deciding how to keep it. How to store Pokémon cards goes through which combination of sleeve, binder and toploader suits which card.
