Pitching W 48 Gap W 52 Sand W 56 Lob W 60
A traditional pitching wedge is 48 degrees, although that changes from manufacturer to manufacturer. From there you can buy a wedge from 48 to 64, and anywhere in between. There are also other characteristics that change, such as bounce angle, that makes some clubs useful for sand and others useful for "all-around" play. Different brands call their wedges different things, such as pitching, gap, sand, approach, lob, first, second, and third, etc. In general, the higher the degree of loft the higher the flight of the ball, and the shorter the distance of the ball's flight. To expand a little..... Pitching - 48 degrees Gap - 52 degrees Sand - 56 degrees Tack - 58 degrees Lob - 60 degrees These are just the most common wedges. They come in all degrees between 50 and 64.

The "A" wedge is sometimes lumped with the Gap wedge although increasingly more often they are split out for the gap to be defined as 50-54 degrees while the "A" (or approach) wedge is between 46 and 50. These have increased in popularity as manufacturers have decreased the loft of irons for the purposes of range through the 90's as more and more golfers (whether by improved skills, manufacturing techniques or "forgiveness") were able to hit short irons much more consistently.The Nike golf site lists the A wedge as a 50 degree loft and 64.5 degree lie.
