The best card sleeves depend on the job: a 66 × 92 mm penny sleeve for bulk, toploaders and grading, a 64 × 89 mm perfect fit inner sleeve under an outer sleeve for cards you play or value most, and a slab sleeve for graded cards. For a tournament deck, double sleeve: perfect fit inner first, then an opaque-backed deck sleeve. Whatever you buy, check that it is acid-free and PVC-free.
This guide compares penny, inner (perfect fit), deck and slab sleeves by size, use and what they fit, then shows how to double sleeve and which sleeve goes with which holder. For why sleeve thickness matters, see our guide to 50-micron sleeves.
Bulk and toploaders: Penny sleeves: 66 × 92 mm, 100 per pack, crystal clear, acid-free, no PVC; fit standard toploaders.
Best protection for a raw card: A 64 × 89 mm perfect fit inner sleeve inside a penny or deck sleeve (double sleeving).
Tournament decks: Perfect fit inner plus an opaque-backed deck sleeve; every sleeve in the deck must match.
Graded cards: PSA graded card sleeves fit standard PSA slabs (and some CGC and M3 holders); acid-free, PVC-free.
Grading submissions: PSA asks for a clear penny sleeve as the first layer, inside a semi-rigid holder.
1. What are the best card sleeves?
Short answer: There is no single best trading card sleeve; there is a best sleeve for each job. Penny sleeves are the everyday layer, perfect fit inners are for double sleeving, deck sleeves are for shuffling, and slab sleeves are for graded cards. Most collectors use at least two of them.
| Sleeve | Size | Best use | What it fits |
|---|---|---|---|
| Penny sleeve | 66 × 92 mm | Bulk storage, toploaders, grading submissions, outer layer over an inner | Standard-size cards; slides into standard toploaders |
| Inner (perfect fit) sleeve | 64 × 89 mm | First layer when double sleeving; snug fit for binder or deck | Standard-size cards (about 63 × 88 mm); too loose for Japanese-size cards |
| Deck sleeve | Check the pack (sizes vary by brand) | Shuffling and tournament play; outer layer over an inner | Standard-size cards, or a card already in a perfect fit inner |
| Slab sleeve | Cut for standard PSA slabs | Keeps dust and scratches off graded slabs | Standard PSA slabs and some CGC and M3 holders; not raw cards |
Our penny, perfect fit and slab sleeves are clear polypropylene, acid-free and PVC-free, and all of our sleeves carry a 1-year guarantee. You can see them side by side in our card sleeves collection.
2. Penny sleeves: the first layer for bulk, toploaders and grading
Short answer: A penny sleeve is a loose, clear outer sleeve and the first layer most cards ever get. Use it for bulk, inside toploaders, and as the first layer on cards you send for grading.
- Size: our standard (penny) sleeves are 66 × 92 mm, 100 per pack, crystal clear, acid-free and free of PVC.
- Toploaders: they fit standard toploaders, and the sleeve keeps the card from rubbing against the hard plastic. Our toploader guide covers which toploader to choose.
- Grading: PSA's shipping guide asks for each card in a clear penny sleeve inside a semi-rigid holder, not a toploader. See our Pokémon card grading guide for which grader to use.
- Limits: the loose fit is quick to load but lets the card slide, so a penny sleeve on its own is not built for shuffling.
3. Inner (perfect fit) sleeves: the snug layer for double sleeving
Short answer: An inner, or perfect fit, sleeve hugs a standard card with almost no spare room. It is the first layer when you double sleeve, so the outer sleeve has a sealed, smooth card to hold.
- Size: our precise fit inner sleeves are 64 × 89 mm, 100 per pack, crystal clear, acid-free and free of PVC, made for double sleeving.
- Top or side loading: the top-loading version opens on the short edge, which gives a four-edge seal inside an outer sleeve. The side-loading version opens on the long edge, so the inner does not ride up while you push the card into the outer sleeve.
- Fit: standard-size cards of about 63 × 88 mm. Japanese-size cards sit loose in them.
- Not for: use on their own in a toploader or for grading; pair them with an outer sleeve.
4. Deck sleeves: for shuffling and tournament play
Short answer: Deck sleeves are thicker outer sleeves with a clear front and a solid-color back. They are built for shuffling, and a matching set hides any marks on the card backs.
| Finish | Good for | Trade-off |
|---|---|---|
| Matte | Competitive play; less glare and smoother shuffling | Softens the shine of holo cards a little |
| Glossy | Casual play and showing off foils | Shows fingerprints and glare |
At most events every sleeve in your deck must be the same and unmarked, so replace sleeves that split, fray or pick up marks, and check your event's rules before you play. Sizes vary by brand, so check that the pack says it fits standard-size cards and that it takes a perfect fit inner if you plan to double sleeve. One Piece players also need to sleeve DON!! cards in a way that tells them apart; see our DON!! sleeves guide.
5. Double sleeving: how to layer sleeves
Short answer: Put the card in a perfect fit inner sleeve, then slide it into an outer sleeve from the opposite end so the openings face different ways. All four edges end up covered.
- Slide the card into a 64 × 89 mm perfect fit inner, top first.
- Turn the inner-sleeved card so its open end goes in first, and slide it into the outer sleeve (a deck sleeve to play, or a penny sleeve to store).
- Press out any trapped air from the bottom up so the deck lies flat.
| Goal | Layers | Then store in |
|---|---|---|
| Tournament deck | Perfect fit inner + deck sleeve | A deck box |
| Raw card you value | Perfect fit inner + penny sleeve, or a penny sleeve alone | A toploader or a side-loading binder |
| Bulk | Penny sleeve, or none for true bulk | A storage box or binder; keep stacks in a team bag |
| Grading submission | Penny sleeve | A semi-rigid holder, as PSA asks |
| Graded card | Slab sleeve over the slab | A slab box or display |
Bundling a stack of sleeved cards or toploaders? Our team bags are 86 × 139 mm resealable bags that hold about 35 penny-sleeved cards or several 3 × 4 toploaders.
6. Slab sleeves: protecting graded cards
Short answer: A slab sleeve is a clear outer bag for a graded slab. It keeps dust, fingerprints and scratches off the case when you stack, store or carry slabs.
Our PSA graded card sleeves fit standard PSA slabs and some CGC and M3 holders, are acid-free and PVC-free, and close with a resealable lip. They are not for raw cards or toploaders, and a sleeve does not stop corner knocks, so store slabs upright in a box.
7. Which sleeve fits which card?
Short answer: Our sleeves fit standard-size cards: Pokémon, One Piece, Magic: The Gathering, Lorcana and most sports cards. Japanese-size cards are smaller: they fit a penny sleeve with extra room, but standard perfect fit inners are too loose.
| Card or holder | Sleeve to use | Next layer |
|---|---|---|
| Standard-size card (about 63 × 88 mm) | Penny sleeve, or perfect fit inner + outer sleeve | Toploader, binder, deck box or semi-rigid holder |
| Japanese-size card | Penny sleeve (loose fit) | Toploader or binder |
| Card in a 3 × 4 toploader | Penny sleeve inside the toploader | Team bag for a stack |
| Graded slab | Slab sleeve | Slab box or display |

8. How to store sleeved cards
Short answer: Keep sleeved cards somewhere cool, dry and out of direct sun, and replace sleeves that split, cloud or get marked.
- Keep cards away from heat and direct sunlight, which can warp sleeves and fade cards.
- Avoid damp rooms; humidity can make cards curl inside their sleeves.
- Do not overfill boxes or binder pockets; one card (or one double-sleeved card) per pocket.
- Check deck sleeves often if you play a lot, and swap the whole set when one splits or picks up a mark.
- Wipe outer sleeves with a dry microfiber cloth; do not use household cleaners on them.

10. Card sleeves FAQ
Q: What are the best card sleeves?
A: It depends on the card. For a card you play or value most, the best setup is a 64 × 89 mm perfect fit inner sleeve inside an outer sleeve. For bulk cards and cards going into a toploader, a 66 × 92 mm penny sleeve is enough. Graded cards need a slab sleeve over the slab. Pick sleeves that are acid-free and PVC-free.
Q: What is the difference between penny sleeves and perfect fit sleeves?
A: A penny sleeve (66 × 92 mm) is a loose outer sleeve: quick to load, made for bulk storage, toploaders and grading submissions. A perfect fit sleeve (64 × 89 mm) hugs a standard card and is made to be the inner layer when you double sleeve. You can use a penny sleeve as the outer layer over a perfect fit, but not the other way round.
Q: What size are perfect fit sleeves for Pokémon cards?
A: Perfect fit inner sleeves for Pokémon cards are 64 × 89 mm, cut for standard-size cards of about 63 × 88 mm. Penny sleeves for the same cards are 66 × 92 mm. Japanese-size cards are smaller, so standard perfect fits sit loose on them.
Q: Do I need to double sleeve my cards?
A: Not for bulk. Double sleeve the cards you shuffle in a deck or the ones you value most: put the card in a perfect fit inner first, then slide it into an outer deck sleeve or penny sleeve from the opposite end so all four edges are covered.
Q: Do penny sleeves fit in toploaders?
A: Yes. Our 66 × 92 mm penny sleeves fit standard 3 × 4 inch toploaders, and a sleeve is the layer that keeps the card from rubbing against the toploader. See our toploader guide for which toploader to pick.
Q: Which sleeves do I need to send cards to PSA for grading?
A: A clear penny sleeve as the first layer. PSA's shipping guide asks for each card in a clear penny sleeve inside a semi-rigid holder and says not to use toploaders. Our grading guide covers which grader to pick.
Q: Do these sleeves fit One Piece, MTG and sports cards?
A: Yes, if the cards are standard size (about 63 × 88 mm). That covers Pokémon, One Piece, Magic: The Gathering, Lorcana and most sports cards. Japanese-size cards fit in a penny sleeve with extra room but are too small for standard perfect fit inners.
Q: What are the best card protectors?
A: Use a sleeve plus a holder that suits how you keep the card: a penny sleeve and toploader for single cards, sleeved cards in a side-loading binder for sets, and a slab sleeve over graded cards. Keep stacks together in a team bag. Our penny, perfect fit and slab sleeves are acid-free and PVC-free, and all carry a 1-year guarantee.
