Pitching Wedge Loft. A typical pitching wedge contains about 45 degrees of loft. By comparison, the highest-lofted iron, the 9-iron, contains approximately 41 degrees of loft, while the gap wedge is typically lofted at 50 degrees. There is, however, no industry standard regarding each clubâs loft. Some manufacturers will build pitching wedges with more or less than 45 degrees of loft.
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.
