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.
Lob Wedge. The lob wedge is the most lofted club in a golfer's bag, typically with a loft of 58 to 60 degrees, although some club manufacturers are offering lob wedges with up to 64 degrees of loft. The lob wedge may also be identified as the L-wedge or UL-wedge, for the ultra lob or 64-degree wedge.
