The One Piece Card Game has a unique deck structure compared to most TCGs, which means not every deck box fits it correctly. Getting the sizing right before you print or buy saves a frustrating reprint. Here’s the exact card count, sleeve dimensions, and box size targets for every One Piece TCG configuration.
One Piece TCG Deck Structure
A standard One Piece TCG deck contains 50 main deck cards plus 1 Leader card, played separately in its own zone. You also have 10 Don!! cards used as a resource during play. That gives you three distinct card groups to store.
Card dimensions are identical to Magic: The Gathering: 63 x 88mm. Any sleeve designed for MTG fits One Piece TCG cards. Dragon Shield Mattes, Ultra Pro Mattes, and KMC Hyper Mattes are all compatible.
Target Internal Dimensions for One Piece Deck Boxes
For the 50-card main deck in Dragon Shield Mattes (single sleeve): internal width 68mm, depth 94mm, height approximately 20-22mm. The 50-card sleeved deck is noticeably shorter than a 60-card MTG deck, so many 60-card boxes have extra headroom that allows the deck to shift during transport.
A purpose-built One Piece box with a Leader card slot holds the 51-card playing set in divided compartments. The OreKo One Piece deck box is designed specifically for this format with interchangeable Jolly Roger and Luffy Gear 5 cap designs.
For storing Don!! cards alongside the main deck, the OreKo Deck Maker Set includes dedicated compartments for Leader, main deck, and Don!! cards in one organized box.
Frequently Asked Questions: One Piece TCG Deck Sizing
What size deck box do I need for One Piece TCG?
A box with internal dimensions of approximately 68-69mm wide, 94-95mm deep, and 22-24mm tall for a single-sleeved 50-card main deck. This leaves comfortable room without the deck rattling. For double-sleeved (inner + outer sleeve), increase height to 28-30mm.
Are One Piece TCG cards the same size as MTG?
Yes. Both use the standard 63 x 88mm card size. Any sleeve, deck box, or storage solution designed for MTG standard-size cards works for One Piece TCG.
Do I need a special box for the Leader card?
Not technically, but a box with a dedicated Leader slot keeps it separate from the 50-card main deck and prevents the Leader from getting bent or marked differently during shuffling. Well-designed One Piece deck boxes include this compartment.
