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 high-lofted club, such as a sand wedge would have a loft somewhere about 55-degrees. Lob wedges can go as high as 64-degrees. But that's about the practical limit for a club. You only need about 60-degrees to make a perfect flop shot.
