Trading card sizes: the complete chart

The standard: 63 × 88 mm

Virtually every modern trading card game — and most sports cards — uses the poker-size card: 63 × 88 mm (2.5 × 3.5 inches). It's the size your hands already know, the size every sleeve and binder is built for, and the size Card Forge designs at natively (630 × 880 px, exactly 10 px per millimeter).

Unless you have a specific reason to deviate, use this size. Compatibility with the sleeve-and-binder ecosystem is worth more than a novel shape.

The full size chart

Common card formats and where you'll meet them:

• Poker / trading card — 63 × 88 mm (2.5 × 3.5") — TCGs, sports cards, the default
• Bridge — 57 × 88.9 mm (2.25 × 3.5") — narrower; some board games
• Japanese TCG small — 59 × 86 mm — several Japanese games run slightly smaller
• Mini / board-game small — 44 × 63 mm — game components, tokens
• Tarot — 70 × 120 mm — divination decks and oversized display cards
• Oracle (common) — 89 × 127 mm (3.5 × 5") — many indie oracle decks
• Business card — 89 × 51 mm (3.5 × 2") — landscape; loyalty-card hacks

Sleeves that match

Sleeve sizing runs a couple of millimeters over the card. For poker-size cards: standard sleeves are ~66 × 91 mm, 'perfect fit' inner sleeves are ~64 × 89 mm (for double-sleeving), and 9-pocket binder pages assume the poker footprint. Japanese-small sleeves (~62 × 89 mm) exist separately — a Japanese-size card swims in a standard sleeve.

Tarot needs dedicated 70 × 120 mm sleeves; they're common in board-game shops thanks to tarot-sized game cards.

Print resolution at each size

For clean printing aim at 300 DPI: poker size wants ~750 × 1050 px, tarot ~830 × 1420 px. Card Forge's 630 × 880 px canvas exports upscale cleanly to poker-size print; if you're printing tarot-size from a card design, choose a template with a generous border so the layout breathes at the larger trim.
