A: Most of our card games have the same size cards, a slightly narrower type many would call “bridge sized” though that’s not a precise category. The card size (roughly, using a ruler) is 87.5 mm tall by 57 mm wide.
This is for Fluxx, Chrononauts, Just Desserts, Loonacy, Are You The Traitor, Are You a Werewolf.
I could swear Choose One cards are just a hair wider on the short side, but they’re VERY close.
Seven Dragons and the old Aquarius and old Nanofictionary are 88.5 mm tall by 63 mm wide. Current Nano and Aquarius are the same size as Fluxx etc.
Zendo cards are the same size as the Pyramid Arcade deck, which is aaaalllmmost the same size as Aquarius cards. But not quite.
