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.
It depends a lot on the loft of the pitching wedge. The A wedge is synonymous with the Gap wedge or GW. Ping uses the term UW for some of its A wedges. I always check the company website to be sure. An A wedge is usually a type of gap wedge, and it tends to fall in between the pitching club and the sand wedge. That means it could fall anywhere between 45 and 55 degrees. I have to add that I don't really use terms like sand wedge, lob wedge, gap wedge, or approach wedge anymore. I custom built my wedge set.
