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.
A gap wedge's angle varies between 50 and 54 degrees. The pitching wedge is usually around 45 degrees while the sand wedge is between 54 and 58 degrees. Golf club makers have decreased pitching wedge loft degrees over recent years, with the gap wedge becoming an option for golfers.
