Pitching wedges have a loft of between 46 and 48 degrees. Approach wedges have lofts between 50 and 52 degrees. The extra loft on the approach wedge helps it to get up in the air, but decreases the distance hit.
Pitching wedges are often the first wedge a beginning golfer plays, since theyâre generally packaged with a set of irons. The loft angle of a pitching wedge is between 46 and 50 degrees, depending on manufacturer, and is typically used from the fairway for shots requiring 100 to 120 yards of distance. It can also be used as an all-purpose wedge, but most are better off adding another wedge to their bag.
