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 pitching wedge is a wedge used to hit a shot with higher and shorter trajectory than a 9-iron and a lower and longer trajectory than a gap wedge.his is for a number of reasons: first, before the term wedge became common for high-loft short irons, the pitching wedge was actually numbered as the 10-iron of a matched set, and to this day it follows the normal loft progression of the numbered irons.
