Magic, Yu-Gi-Oh!, One Piece and Lorcana card sizes

Magic, One Piece and Lorcana cards are standard size, the same class as Pokémon, and take the common 66 by 91 mm sleeve. Yu-Gi-Oh! cards are smaller and have their own class of sleeve, 62 by 89 mm, sold as small or Japanese-size sleeves. That one split decides almost every supply you buy: sleeves, inner sleeves and the snugness of a toploader. Where a figure is converted or compared, it is Rip.fan’s arithmetic.

Which card games are standard size?

Sleeve makers sell a standard class and a smaller class of trading card sleeve, and name the card games each one fits.

Ultimate Guard lists One Piece and Lorcana as standard size.

By Rip.fan’s conversion, a standard card is about 63.5 by 88.9 mm and a Yu-Gi-Oh! card about 58.7 by 85.7 mm. The difference is about 5 mm across and 3 mm top to bottom, which is why a standard card can’t go in the smaller sleeve. Our guide to Pokémon card sizes and sleeves works through the standard class in detail.

What does Japanese size mean on a sleeve pack?

A card size. Japanese-size and small sleeves are both made for Yu-Gi-Oh! cards. A Japanese-language card from a standard-size game is a different matter: our Pokémon sizes guide found that Pokémon’s own sleeves, sold in Japan, sit in the standard class. Go by the millimeter figure on a pack and ignore the word on its front.

Which sleeves fit each card game?

Ultimate Guard’s inner sleeves are made to fit inside its own outer sleeves, and other brands may affect the fit. Ultra PRO allows a tolerance of plus or minus 0.5 mm on its sleeves.

How much room does each layer leave in the Japanese class?

The Pokémon guide covers the standard layers.

The gaps compare each sleeve’s listed size with what goes inside it, so the real clearance is a little less. A sleeve within Ultra PRO’s plus or minus 0.5 mm tolerance can also be half a millimeter smaller than its label, so read the inner gaps as snug at best.

Can you mix the classes?

One way only. A standard card won’t go in a Japanese-size sleeve: at about 63.5 mm wide, it is wider than the 62 mm sleeve. A Yu-Gi-Oh! card will go in a standard sleeve, loosely. BCW’s standard penny sleeves suit Yu-Gi-Oh! cards and measure 2 5/8 by 3 5/8 inches outside, which by Rip.fan’s arithmetic is about 8 mm wider and 6 mm longer than the card, a little less inside. The card can move about in it, and a 62 by 89 mm sleeve gives the closer fit.

How many sleeves come in an official pack?

Konami and Bandai sell sleeves under their own names, and recent packs come in different counts. Match them to the class above.

• Konami’s THE CHRONICLES card sleeves, from October 2025, come 50 to a pack and are designed to meet tournament standards for Yu-Gi-Oh! cards.
• Bandai’s two limited One Piece sleeve sets, sold at its Fest 26-27 events, hold 70 sleeves each, at an MSRP of $10.00.

Do toploaders take every card game?

Yes, with more room for the smaller cards. BCW’s 3x4 toploader measures 2 3/4 by 3 7/8 inches inside and suits Pokémon and Magic cards. By the measurements, a Yu-Gi-Oh! card fits too, with extra space around it, and BCW’s standard penny sleeves are made to fit inside these holders. For thickness, BCW’s January 2026 guide puts most TCG cards in the 20pt to 35pt range that fits a standard toploader. Our toploader entry explains the holder, and the guide to storing trading cards covers boxes and binders, as does our guide to building a card binder.

Will a grading company take each card game?

CGC takes cards up to 2-5/8 by 3-3/4 inches (6.6 by 9.5 cm) and up to 7.25 mm thick, so cards from all four games fit. Cards smaller or larger than standard sizes may go in its holder with a protective inner sleeve, which could apply to a smaller Yu-Gi-Oh! card. Some thick cards with irregular dimensions can’t be encapsulated, and CGC sends those back raw with the grading fee refunded. Our guide to grading Magic, Yu-Gi-Oh! and One Piece cards covers which services take each game, and the slab entry explains the holder.

Which size should you buy?

1. Magic, One Piece or Lorcana: standard sleeves of 66 by 91 mm, and standard inner sleeves of 64 by 89 mm if you double-sleeve.
2. Yu-Gi-Oh!: small or Japanese-size sleeves of 62 by 89 mm, and Japanese inner sleeves of about 60 by 87 mm.
3. A mixed collection: keep the two classes apart, and check the millimeter figure on every pack.
4. Before handling a valuable card: see our guide to handling cards safely.

Our sleeve and supplies finder lists the sleeve, toploader and page sizes the makers give for each card game, and counts the sleeves, pages and toploaders a number of cards needs.

Frequently asked questions

How can you tell small and standard Ultra PRO sleeves apart on the shelf?

By the label color. Ultra PRO's Standard Size PRO-Gloss and PRO-Matte sleeves carry a black label, and the Small Size versions made for Yu-Gi-Oh! carry a white one.

Which other card games take standard sleeves?

Dragon Ball Super, Force of Will and Flesh and Blood all use the standard class, and so do most modern sports cards, so one stock of 66 by 91 mm sleeves covers them as well.

Do inner sleeves come in side-loading versions?

Yes. Ultimate Guard's Precise-Fit inner sleeves come in top-loading, side-loading and resealable versions, sized to sit inside its Katana and Cortex outer sleeves.

Which card sizes can TAG grade?

Cards of 2.5 by 3.5 inches. TAG grades card games of that size, among them Magic, Pokémon, One Piece, Disney Lorcana and Star Wars Unlimited, but it does not accept bridge-size cards such as Yu-Gi-Oh! and Bandai Carddass releases.
