Sleeve King

Standard Card Game Sleeves (63.5 X 88mm): This is THE single most useful size sleeve to own, as it is good for MTG and literally thousands of games!  If you don't have a few extra packs of these on hand you're crazy!

Standard European Sleeves (59x92mm):  These fit HUNDREDS of games as well and we recommend you keep an extra pack or two around if you are big gamers as they are VERY useful.

Standard American Sleeves (57x89mm): Because of our more generous sizing these will fit both cards that are 56 X 87 MM,  57.5 X 88 MM, and 57 X 89 MM.  

Mini European Sleeves (44 X 68mm): These are the "european standard" for mini cards.  This is actually the MOST common mini-card size in the board game industry.
