Which Sleeve Size for Which TCG? Standard and Japanese Size Explained

Last updated: 08-2026

If you're standing in front of the sleeve shelf with a pack of cards in your hand, here's the short answer first: For Yu-Gi-Oh! and Cardfight!! Vanguard you need Japanese size (62x89 mm), for practically everything else standard size (66x91 mm). That covers a good ninety percent of all cases, and if you're in a hurry, you're done here.

For everyone else, it's worth sticking around for a minute. The size question has a few quirks that catch up with you sooner or later, and knowing them saves you the drawer full of sleeves in the wrong size that almost every collector has somewhere.

Why the pack shows a different number than your card

Your Pokémon or Magic card measures 63x88 mm, but the matching sleeve is labeled 66x91 mm. That confuses almost everyone on their first purchase, yet both numbers are correct: one describes the card, the other the sleeve, and a sleeve has to be a few millimeters larger than what goes inside it. You always buy by sleeve size. So if you're looking for Yu-Gi-Oh!, you need sleeves in 62x89 mm, even though the cards themselves measure 59x86 mm.

You'll find both sleeve sizes with us:

Japanese doesn't mean Japanese size

The table contains one small trap that we walked into ourselves: Weiss Schwarz. The game comes from Japan, is published by Bushiroad and is full of anime artwork, yet the cards are perfectly ordinary 63x88 mm. When we set up our lineup, we first filed it under Japanese size; only on closer inspection did it become clear that Bushiroad prints only its sister game Cardfight!! Vanguard in the smaller format.

"Japanese size" describes a card measurement, not an origin. Dragon Ball Super, Union Arena, Digimon: all Japanese games, all standard size. And Japanese Pokémon cards are exactly the same size as the English ones, 63x88 mm worldwide. If you order small sleeves for your Japanese imports just to be safe, you're buying something you don't need.

In the end, out of the vast Japanese card universe, exactly two games remain in the smaller format, and you now know both of them.

Where a millimeter starts to matter

"Standard" sounds standardized, but it isn't. With the established manufacturers you know what you're getting: the cut is precise, the measurement is printed on the pack, and a sleeve from the next pack is the same size as the one from the last. With the cheap bulk sleeves you'll find on the usual platforms for a few francs per thousand, that's exactly what isn't guaranteed. Those sleeves tend to come out a millimeter larger or smaller, sometimes within the same pack, and the material is often so thin that the opening tears when you insert a card. In everyday use you only notice it when things get tight somewhere: in a narrowly cut deck box, in tightly filled binder pages, or when double-sleeving, where a fluctuating outer sleeve wrecks the whole combination.

So here's our advice from experience: for your deck and for anything you care about, brand-name sleeves are worth it, and when buying more, you're best off staying with the same product line, because even clean lines differ slightly in cut and surface. That's why we've bundled the individual manufacturers' lines:

The good news concerns double-sleeving: inner sleeves are remarkably consistent across brands at 64x89 mm, so inner and outer sleeves can be combined without trouble in the vast majority of cases.

And if you really don't know: measure the card

For games that appear in no table, there's a more reliable route than any forum discussion. Lay a card flat and measure it. Around 63x88 mm means standard, around 59x86 mm means Japanese, and you're certain before the order goes out. It takes half a minute and can save you a return.

A quick word on buying

For playing, matte deck sleeves in the right size for your game are your best choice, and buy one more pack than your deck needs. That way you have spares from the same batch if a sleeve gives out, and you don't have to hunt for the identical line later on.

For collecting, the priorities are a little different. A sleeve protects against abrasion, dust, and fingerprints, but does little against bends. For valuable singles, a rigid holder is therefore worth adding:

Frequently asked questions

Can I use standard sleeves for Yu-Gi-Oh!?
We'd advise against it. The card floats in the oversized sleeve, shifts around when you shuffle and can even slide out at the open side. For a few francs more it sits properly in Japanese size.

Which sizes do I need for double-sleeving?
An inner sleeve in 64x89 mm plus an outer sleeve in 66x91 mm is the common pairing for standard cards, and several manufacturers offer exactly this combination.

Are thicker sleeves better?
Thicker material provides a more consistent shuffle and feels more solid, but it also takes up more room in your box and binder. For orientation: basic soft sleeves come in at around 45 to 50 microns, premium playing sleeves at 100 to 120. For cards that stay in a binder, thickness matters less; what matters more is that the material is PVC-free, so nothing reacts with the card over the years.
