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.
The loft of the pitching wedge is typically between 45 and 48 degrees and it is mainly used for shots outside of 100 yards â the average club golfer hits a pitching wedge around 105 yards, while the Tour professional carries it around 125 yards.
