With the Naruto Card Game still more than half a year from launch, one practical question keeps coming up: what size are these cards actually going to be, and what sleeves will fit them? As of this writing, Bandai has not published an official millimeter spec.
That gap is worth being upfront about rather than guessing at a precise number that has not actually been confirmed anywhere official. What can be said with confidence comes from looking at the pattern Bandai has already set with its other card games.
One Piece Card Game and Dragon Ball Super Card Game Fusion World, Bandai's two other current TCGs, both use the same 63mm by 88mm card size as Magic: The Gathering and Pokemon, despite being produced in Japan. Every card photo revealed for the Naruto Card Game so far matches that same standard proportion.
This guide covers what is actually confirmed, what is a reasonable expectation based on Bandai's track record, and how to sleeve whatever ends up shipping in June 2027 either way.
No Bandai press release or official card-game page has published an exact card-size spec for NARUTO CARD GAME as of this writing. That is a genuine, honest gap in public information, not a detail being glossed over for convenience.
Anyone citing a precise millimeter figure online right now is extrapolating, not quoting an official source, and it is worth treating any such claim with a healthy amount of skepticism until Bandai actually says so directly.
Both One Piece Card Game and Dragon Ball Super Card Game Fusion World ship at 63mm by 88mm, the same card size used by Magic: The Gathering and Pokemon, rather than the smaller size used by some other Japanese card games.
That is a deliberate, repeated choice across Bandai's current TCG lineup, not a coincidence, and it is the strongest available signal for what to expect from Naruto Card Game cards once they actually ship.
Every card image shared since the July 29 rules reveal, Leader cards, Character cards, Chakra cards, shows standard trading-card proportions consistent with that same 63mm by 88mm format, with no visual indication of an unusual size.
That is not the same as an official confirmation, but it is a meaningfully strong visual data point lining up with the pattern from Bandai's other current card games.
Standard trading card sleeves, the same ones built for Magic, Pokemon, and both of Bandai's other current TCGs, are sized with a small margin over the 63mm by 88mm card itself specifically so a sleeved card still slides cleanly into a toploader or binder page.
That margin is exactly why standard sleeves are the reasonable default purchase right now, since they are not a size-locked, franchise-specific product that risks becoming the wrong fit if a final spec differs slightly from expectation.
If Bandai does eventually confirm a different size closer to launch, existing standard-sleeve stock would not go to waste, since Magic, Pokemon, and dozens of other games already use that exact format day to day.
The real risk sits with anyone who buys a franchise-branded sleeve product sized to a guess rather than an official number, since that is the purchase most likely to need replacing if the final spec lands differently than expected.
Until an official spec exists, the lowest-risk move is buying standard-size sleeves and toploaders that already fit Magic and Pokemon-sized cards, rather than waiting on a franchise-specific product that does not exist yet anyway.
That same logic applies to binders and storage boxes built around the standard trading-card footprint, all of which will carry over cleanly whether or not Bandai's eventual card size lines up exactly with the 63mm by 88mm pattern. A combination of standard sleeves and an inner layer like Perfect Fit Sleeves covers both bases without betting on an unconfirmed franchise-specific size.
No, not as of this writing.
63mm by 88mm, the same as Magic: The Gathering and Pokemon.
Yes, every card image shown so far matches standard trading-card proportions.
A standard-size sleeve built for Magic or Pokemon-sized cards.
Buying standard-size protection today is a safe bet that will not go to waste no matter how the final spec lands. EVORETRO's Card Sleeves already fit the same format used by Bandai's other current TCGs.
If Bandai does confirm something different closer to June 2027, this guide will be updated, but there is no good reason to wait on basic protection in the meantime.
