Collecting and care
One question decides what you buy: the size of the card. This page states it, shows what fits what, and explains why the same answer covers every series on this site.
Quick answer
Every GUNDAM CARD GAME card is 63 × 88 mm. That is the standard trading-card size and the same measurement used by Pokémon, One Piece, Dragon Ball and Naruto cards, so there is no separate Gundam size to shop for: a standard-size sleeve, a rigid holder and a standard binder page all fit, and a mini or Japanese-size sleeve does not.
The dimension
Every GUNDAM CARD GAME card is 63 × 88 mm. That is the standard trading-card size, and it is the same measurement used by Pokémon, One Piece, Dragon Ball and Naruto cards. There is no separate Gundam size to shop for.
What that means in practice
| Item | Fits? | Note |
|---|---|---|
| Standard-size sleeve | Yes | The everyday answer for handling and play. |
| Rigid holder or toploader | Yes | Adds stiffness; used for cards that travel. |
| Binder page for standard cards | Yes | Check that the pocket holds the sleeved card, not just the bare card. |
| Sleeve sized for a mini or Japanese-size card | No | Too small. Mini-size is a different format. |
Sleeve inside a holder
The usual arrangement is a sleeve first, then the rigid holder. The sleeve takes the handling and the holder stops the bend. Measure the sleeved card, not the bare one, if you are choosing a holder to put over it.
Why one size covers every series
Trading-card games have converged on a single card size, and the GUNDAM CARD GAME uses it too. So the protection you already have for Pokémon cards fits these, and vice versa. That is why this section of the site shares a protection guide with the others rather than having its own.
Cards that are not card-sized
Nothing in this game is printed at a size other than the standard one, so there is no large-format exception to plan for among the 1,148 cards we index.
We make sleeves and rigid holders in this size: card protectors. For the practical side — what damages a card and how to store it — see storing and protecting Gundam cards.
Frequently asked questions
What size sleeve fits Gundam cards?
A standard-size sleeve, for a 63 by 88 millimetre card. That is the same sleeve that fits Pokémon, One Piece, Dragon Ball and Naruto cards.
Are Gundam cards bigger than Pokemon cards?
No. They are printed at the same 63 by 88 millimetres, so the two are interchangeable as far as sleeves and holders are concerned.
Do I need a sleeve and a rigid holder?
They do different jobs. The sleeve takes handling and stops edge wear; the rigid holder stops the card bending. Most collections use the sleeve as standard and the holder for cards that leave the house.
Will a sleeved card still fit in a binder?
Often, but it depends on the binder. Check the pocket against a sleeved card rather than a bare one before committing a whole binder to it.
