Yes — One Piece cards and Pokémon cards are the same standard trading card size.
Both typically measure:
- 63 mm × 88 mm
- Also known as “standard size” or “TCG size”
That means accessories made for Pokémon cards will usually work perfectly for One Piece Card Game cards, including:
- Card sleeves
- Top loaders
- Binder pockets
- Deck boxes
- Storage cases
This is also the same size used by many other trading card games, including:
- Yu-Gi-Oh! Master Duel cards are actually smaller physically in the real-life TCG
- Magic: The Gathering
- Disney Lorcana
One important exception: physical Yu-Gi-Oh! cards are slightly smaller than Pokémon and One Piece cards, so Yu-Gi-Oh sleeves will be too tight for One Piece cards.
