Quick answer
CardSpicy indexes Pokémon, One Piece, Gundam, Dragon Ball and Naruto and stocks the sleeve range below them, and one sleeve size covers every one of those games because they share one physical measurement — 63 × 88 mm.
Pokémon, One Piece, Gundam, Dragon Ball and Naruto cards look nothing like each other and measure almost exactly the same. CardSpicy indexes all five lines and stocks the sleeve range below them, and the reason one set of sleeves covers every game is a single physical number.
The one line: the printed card is 63 × 88 mm across every game we index, so a sleeve bought for one game fits the rest. What changes between games is thickness, not footprint — and thickness is the one thing a sleeve is rated for.
The number that makes it true
Standard trading cards in these games are 63 × 88 mm — roughly 2.5" × 3.5". That is the size the sleeves, rigid holders, binders and boxes in this store are built around, and it is a deliberate standard rather than a coincidence: a card game that wants its cards in existing accessories has an obvious reason to use the size that accessories are already made in.
The footprint being shared is what allows one sleeve to serve several collections at once. The thickness is not shared, which is why the same shelf holds six different PT ratings.
Which games use the same card size
| Game | Card size | Fits a 63 × 88 mm sleeve |
|---|---|---|
| Pokémon | 63 × 88 mm | Yes |
| One Piece Card Game | 63 × 88 mm | Yes |
| GUNDAM CARD GAME | 63 × 88 mm | Yes |
| Dragon Ball Fusion World | 63 × 88 mm | Yes |
| Dragon Ball Super Card Game (Masters) | 63 × 88 mm | Yes |
| Magic: The Gathering | 63 × 88 mm | Yes |
| Yu-Gi-Oh! | Approximately 59 × 86 mm | Fits, but loosely — see the exceptions below |
Five of the lines we index are the same physical object as far as storage is concerned. That is the practical value of the standard, and it means the protection question does not restart when you start a second collection.
Where the games actually differ
Once the footprint is fixed, the remaining differences are the ones that affect what you buy.
- Thickness. Different games and different printings use different card stock, and a thin card and a thick one want different PT ratings. This is the number to check, and it is the reason our sleeves come in six thicknesses rather than one.
- Surface treatment. Foils, textured finishes and embossed prints all sit differently against a clear film, which is why an ultra clear sleeve is worth choosing rather than a merely transparent one if the card will be viewed or photographed sleeved.
- Slabs. A graded card is outside all of this. A slab is larger than the card in both dimensions and needs slab-sized storage, whichever game the card came from.
What this means when you buy
It simplifies the decision to two questions, and neither is about the game.
- Is the card raw or graded? Raw cards take a sleeve and, if they will be under load, a rigid holder. Graded cards take neither, and take a bag and a slab box instead.
- How thick is the card? That sets the PT rating, and the rating is what decides whether the sleeve fits. The way to work it out is in the sleeve thickness guide.
Everything else — which game the card is from, which set it was printed in, which language it is printed in — does not change the answer, because it does not change the card’s dimensions.
The exceptions worth knowing
Two, and both are cheap to avoid.
Yu-Gi-Oh! cards are smaller than standard. They are around 59 × 86 mm, so a 63 × 88 mm sleeve will accept them and will not grip them — the card slides. A standard-size sleeve is still the wrong fit for a card that is deliberately smaller, and the fix is a sleeve sized to that card.
Not every Chinese-language card line publishes a standard size. Where a card line uses its own stock and its own printing, the dimensions are worth checking against that card rather than assuming the 63 × 88 mm standard. If you are unsure, measuring the card you actually have settles it in seconds and is faster than searching for a specification.
The full index of cards we cover, by game, is on the collector’s index, with each line indexed separately: One Piece, Gundam, Dragon Ball and Naruto.
Frequently asked questions
Do the same sleeves fit Pokémon and One Piece cards?
Yes. Both are 63 × 88 mm, so a sleeve sized for one fits the other. The same applies to Gundam, Dragon Ball Fusion World and Magic: The Gathering. What you may need to change between games is the PT rating rather than the sleeve size.
Are all trading cards the same size?
No, but most of the games we index are. The widely used standard is 63 × 88 mm, and it covers Pokémon, One Piece, Gundam, Dragon Ball and Magic. Yu-Gi-Oh! cards are smaller at around 59 × 86 mm, which is why they sit loose in a standard sleeve.
Will a sleeve bought for Pokémon cards fit Gundam cards?
Yes. Both card types share the 63 × 88 mm footprint, so the sleeve fits both. Choose the PT rating to match the card’s thickness, since that is the dimension that differs between printings.
What about graded cards from different games?
Grading takes a card out of the standard-size conversation entirely. A graded slab is larger and thicker than the card and is not interchangeable with sleeves or rigid holders made for raw cards, regardless of which game the card came from.
How do I check a card I am not sure about?
Measure it. A standard card measures about 63 mm across by 88 mm down, so a card that is noticeably narrower or shorter is not standard size, and the sleeve has to be matched to it rather than to the standard.
