Card Sizes and Sleeve Sizes: The Complete Chart
Updated Wednesday, September 16, 2026 · by the CardsNearby team
Almost every modern trading card — sports, Pokémon (international), Magic, Lorcana, One Piece — is the same size: 2.5 × 3.5 inches (63.5 × 88.9 mm). The confusion starts with the protection stack: sleeves, toploaders, and magnetic holders each come in sizes that only make sense once you know card thickness is measured in 'points' (1 pt = 0.001 inch).
Key facts
- ▸Standard trading cards measure 2.5 × 3.5 in (63.5 × 88.9 mm); Japanese TCG cards measure 59 × 86 mm.
- ▸Penny sleeves are ~66 × 91 mm; perfect-fit inner sleeves are ~64 × 89 mm.
- ▸Card thickness is measured in points: 1 pt = 0.001 inch; a standard card is ~20 pt; relic cards run 55–180 pt.
- ▸Store cards below ~65% relative humidity at roughly 65–70°F to prevent warping.
Card dimensions
The base sizes you'll encounter:
| Card type | Size (in) | Size (mm) |
|---|---|---|
| Standard trading card (sports, Pokémon INT, MTG) | 2.5 × 3.5 | 63.5 × 88.9 |
| Japanese TCG cards (Pokémon JP, Yu-Gi-Oh!) | 2.32 × 3.39 | 59 × 86 |
| Mini/undersized (some board games, vintage tobacco) | varies | 41 × 63 common |
| Oversized/box toppers | varies | up to 89 × 127 |
Sleeve sizes
The standard stack is sleeve → toploader (or one-touch) for anything worth protecting. 'Perfect fit' sleeves go inside another sleeve; standard sleeves are the outer layer.
| Sleeve | Interior size (mm) | Fits |
|---|---|---|
| Penny sleeve (standard soft) | 66 × 91 | Standard cards |
| Perfect fit / inner sleeve | 64 × 89 | Standard cards, double-sleeving inner layer |
| Japanese-size sleeve | 62 × 89 | Japanese TCG cards |
| Japanese perfect fit | 60 × 87 | Japanese cards, inner layer |
| Team bag | fits toploader | Sealing a sleeved toploader/one-touch |
Toploaders and one-touches by point thickness
Points measure card thickness: a regular base card is ~20 pt, most 'thick' relic and patch cards run 55–180 pt. Match the holder to the card's thickness, not just its footprint.
| Holder | Thickness | Typical use |
|---|---|---|
| Standard 3×4 toploader | 20–35 pt | Base cards, most singles |
| 55 pt toploader | up to 55 pt | Thicker inserts, some relics |
| 75–100 pt toploader | up to 100 pt | Jersey/relic cards |
| 130–180 pt toploader | up to 180 pt | Booklet-adjacent, thick patches |
| One-touch magnetic (35 pt) | 35 pt | Display-grade singles |
| One-touch magnetic (55–180 pt) | matches card | Thick premium cards |
Storage rules that preserve value
Sleeve before toploading (a bare card in a toploader scratches), store upright rather than stacked, and keep cards in a cool, dry, dark place — conservators generally recommend under about 65% relative humidity to prevent warping and around 65–70°F. Never rubber-band anything you might sell.

FAQ
What size are standard trading cards?
2.5 × 3.5 inches (63.5 × 88.9 mm) — the same for sports cards, international Pokémon, Magic: The Gathering, Lorcana, and One Piece.
What size sleeves do Japanese Pokémon cards need?
Japanese cards are smaller (59 × 86 mm) — use Japanese-size sleeves (about 62 × 89 mm) or Japanese perfect-fits for the inner layer.
What does 'pt' mean on toploaders?
Points — thousandths of an inch of card thickness. A standard card is about 20 pt; jersey and patch cards commonly need 75–180 pt holders.
Should I double-sleeve cards?
For anything valuable, yes: a perfect-fit inner sleeve (opening down) inside a standard sleeve (opening up) seals the card from dust and drift inside a toploader or one-touch.
