In the US the standard names for the size of decks would be "Bridge" or "Poker".  Both of these decks can be used for most card games.  The only real difference would be that the "Bridge" size decks are 1/4" narrower than "Poker".  Otherwise they can be used for pretty much anything.  Please read the description of this item for more information.

This has to do with the actual size of a deck of cards, not really whether or not tradional games can be played with it or not.  While here in the US we call most decks either "Poker" or "Bridge" size, most of the rest of the world would call them either "Wide" or "Narrow", respectivily.

Many times the "narrow" decks were intended for ladies or children because it was easier for them to handle.  While the "narrow" are considered the standards size in most of the world, here in the US the "wide" are considered the standard size.
