The short answer: count the cards in your deck, add a margin for sideboard cards and replacements, then round up to the box. Here are the numbers game by game.
Cards per game
| Game and format | Cards to sleeve |
|---|---|
| Pokémon TCG | 60 cards |
| Magic: Standard, Pioneer, Modern… | 60 cards minimum + sideboard (up to 15) |
| Magic: Commander | 100 cards, commander included |
| Magic: Draft, Sealed | 40 cards minimum |
| Riftbound | 40-card main deck + legend, runes and battlefields |
| Disney Lorcana | 60 cards minimum |
| One Piece Card Game | 50 cards + 1 Leader |
| Star Wars: Unlimited | 50 cards minimum + leader and base |
In One Piece, the 10 DON!! cards are kept apart; many players don’t sleeve them, or use a different colour.
Keep spare sleeves
A sleeve that splits or gets damaged during a tournament has to be replaced with an identical one. So always keep spares from the same box: between batches, a slight difference in shade or wear is enough to make a card recognisable. Plan at least ten extra sleeves per deck.
How many boxes to buy?
A Day Two box holds 100 sleeves.
- One Pokémon, Riftbound, Lorcana, One Piece or Star Wars: Unlimited deck: one box covers the deck with plenty of spares.
- One Magic deck with its sideboard: 75 cards, one box is enough, with 25 spares.
- One Commander deck: exactly 100 cards. Take two boxes to have spares.
- Several decks, or a deck you change often: bundles start to make sense.
Bundles of 3 and 5 boxes lower the price per box (up to −10%).
What about cards outside the deck?
Collection cards, valuable cards or a binder of duplicates can be protected too, but not necessarily with the same sleeves as your tournament decks. Keep your playing sleeves for playing: they wear at the same rate and stay identical.
In short
A 60-card deck fits in a box of 100 with room to spare; a Commander deck needs two. To put those sleeves on properly, follow our step-by-step guide.
