Tarot card size
Tarot is the largest standard board game card size: 2.75" × 4.75" (69.85 × 120.65 mm) trimmed. The extra room is useful for detailed artwork, longer rules text, or a more premium feel.
Why it matters
Tarot is the default for divination decks, oracle cards, and games that lean on big illustrations. The tradeoff is shelf space — tarot decks don't fit standard poker boxes or sleeves.
Example
A 78-card divination deck or a story-driven adventure game with a paragraph of flavor text per card both benefit from tarot dimensions. Player hand-feel changes too — tarot cards fan differently than poker.
