what size are playing cards
Most standard playing cards are about 2.5 inches by 3.5 inches, which is roughly 63.5 mm by 88.9 mm.
Standard playing card size
- Poker / “regular” cards : 2.5 in × 3.5 in (63.5 mm × 88.9 mm).
- This is the size used in most classic 52-card decks for games like poker, blackjack, and many modern board games.
The aspect ratio is about 5:7 (width:height), which is why they feel nicely proportioned in your hand and are easy to shuffle.
Other common variations
If you were wondering about alternatives, there are a few other popular formats:
- Bridge cards: about 2.25 in × 3.5 in (slightly narrower but same height as poker cards).
- “Standard” in some printers’ metric specs: often listed as 64 mm × 89 mm (functionally the same as 2.5 in × 3.5 in).
- Large/oversized cards: around 89 mm × 146 mm, used for novelty or easy-to-read decks.

- Common corner radius: around 3.5 mm for standard decks to prevent sharp corners and fraying.
