Hi I'm looking to buy card sleeves as a surprise for a friend who has Struggle for Catan but can't seem to find the cards' dimensions. Please help.
According to this post on boardgamegeek.com:
SwanPanasia 'Standard USA' 57x90mm sleeves are reported to fit these cards perfectly. They are, however, larger than similarly-sized sleeves from other makers, so those other makers 'Standard USA' sleeves may or may not fit these cards.
These fit perfectly, I bought them for a close friend who I play Catan with and he liked them so much he bought a whole bunch more. They only fit the US regular size version not the hand painted wood version with small cards.
