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 sole and design may vary from club to club, but the sand wedge typically is equipped with a loft of 56 degrees. Because of the discrepancy in loft between these two clubs, most players find the distance variations of these clubs to be twice that of the difference between the nine-iron and the pitching wedge.
