Yu-Gi-Oh! is the odd one out on the shelf. Where Pokémon, Magic and most other trading card games settled on a 63 by 88 millimetre card, Yu-Gi-Oh! has used 59 by 86 millimetres since the start. Two millimetres does not sound like much until a card starts sliding around inside a sleeve that was cut for a bigger card, and then it matters every time you pick the deck up. This page covers the size, the three jobs a sleeve can do, and how to holder a card you plan to grade.
Quick answer
Yu-Gi-Oh! cards measure 59 by 86 millimetres. Standard-size sleeves are cut for 63 by 88 millimetres, so they fit loosely and let the card move. The fix is a sleeve cut to the smaller size, often sold as a Japanese-size or small-size sleeve, and it matters most for a played deck because movement is what damages square corners. Beyond fit, there are three layers worth knowing about: an inner sleeve that touches the card, an outer sleeve for the deck, and a rigid holder for storage or grading.
The size that decides everything
Measure a Yu-Gi-Oh! card and you will get 59 by 86 millimetres. Measure a Pokémon or Magic card and you will get 63 by 88. Sleeves are cut to one or the other, and the labels are not consistent between manufacturers: some sell the smaller cut as Japanese size, some as small size, some just as Yu-Gi-Oh! size.
The test is not the label, it is the fit. Slide a card into a sleeve and turn it over. If the card stays put, the sleeve is right. If it slides a millimetre in any direction, the sleeve was cut for a bigger card, and the card is free to rub against its own edges every time the deck moves.
The three jobs a sleeve can do
Inner sleeve. A thin, tight sleeve that goes on first and stays on. It exists to keep the card surface away from everything else, and it should be as close to the card size as possible. This is the layer that does the protecting; everything outside it is doing something else.
Outer sleeve. The sleeve the deck is shuffled in. It has to be the right size for the card, opaque or clear depending on your deck, and replaceable. Outer sleeves take the wear so the card does not, and they wear out — a scuffed outer sleeve is a card that will be marked in a tournament.
Rigid holder. Not for play. A rigid holder exists to stop a card flexing, which matters for storage, for postage and for grading submissions. The common rigid options are a clear rigid sleeve open at the top, a semi-rigid holder that is sealed rather than open, and a full slab once a card has been graded.
Holders, and how they differ
| Holder | What it does | What to watch |
|---|---|---|
| Clear rigid sleeve | Stops the card flexing; the card stays visible and removable. | The open edge lets dust in and a card can slide out if the box is tipped. |
| Semi-rigid holder | Sealed on three sides, so the card cannot leave; the standard shape for grading submissions. | Not reusable; the seal is the point. |
| Graded slab | Permanently sealed with a documented grade. | It is no longer a playable card, and it cannot be opened without destroying the holder. |
Which one you want follows from what you are doing. A deck wants outer sleeves. A card you are posting wants a rigid holder inside a padded box. A card you are submitting wants whatever the grading company asks for, and that is worth checking on their own instructions rather than assuming.
What actually damages cards, and what does not
Most damage happens not because a card was unprotected but because it was protected badly.
- A loose sleeve. The card moves inside it and its own edges do the damage. This is why card size matters more than sleeve quality.
- Two cards in one pocket. They rub against each other face to face, and the foil on a chase card marks first.
- A full binder. Overstuffing bows the pages, and a bowed page presses on the cards near the spine.
- Direct sunlight and heat. Foil and holo layers react to both over time.
- Bare hands on a chase card. Oils sit on the surface and show later, especially under a grader’s lamp.
Putting it together
For a deck: an inner sleeve cut to 59 by 86 millimetres, then an outer sleeve over it, then shuffle gently and replace the outers when they scuff. For a collection: a rigid holder or a binder with pockets cut to the right size, stored upright, out of sunlight. For a card you are grading: handle it once to inspect it, put it straight into a holder, and leave it there.
the card protection range lists the sleeves and holders we keep, and the site’s guide to sleeve sizes covers the generic measurements if you are buying elsewhere. If you are working out whether a card is worth holder-ing in the first place, the grading guide covers which copies are worth the trouble.

Frequently asked questions
What size sleeves fit Yu-Gi-Oh! cards?
Sleeves cut for 59 by 86 millimetres, usually sold as Japanese size or small size. Standard-size sleeves are cut for 63 by 88 millimetres and will fit, but loosely, which lets the card move and rub its own edges.
Do I need an inner sleeve as well as an outer sleeve?
For a deck you play regularly, yes. The inner sleeve is the layer that actually touches the card and keeps it clean; the outer sleeve takes the shuffling wear and gets replaced. For a card that lives in a binder, one correctly sized sleeve is usually enough.
Can I put a Yu-Gi-Oh! card in a standard rigid holder?
Rigid holders come cut for both sizes. Check the holder’s stated card size rather than assuming, because a card that rattles inside a rigid holder can still pick up edge wear on the way in and out.
Will a loose sleeve actually damage the card?
Over time, yes. The damage is edge and corner whitening from the card shifting inside the sleeve. Square corners concentrate that wear at a point, which is why Yu-Gi-Oh! cards show it sooner than rounded-corner cards in the same sleeve.
What about the foiled cards?
Full-coverage foil treatments show handling marks sooner, so sleeve them before you compare two copies side by side. The protective method is the same; the difference is how quickly a mistake becomes visible.
