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 angle of the face of the club with respect to the shaft is called loft. Drivers, 2 and 3 irons have very little loft. Wedges, and short irons have considerable loft by design. And, as your intuition tells you, the more highly lofted a club is, the higher will be the trajectory of your ball. Loft angles are expressed in degrees with respect to vertical rather than the ground.
