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.
Significance. For most of the 20th century the pitching wedge had approximately 50 degrees of loft. In the past 10 years lofts of all irons have been decreased because of perimeter weighting, center of gravity and the ability to fly farther.Now the average loft of a new pitching wedge is 46 degrees.n the early 1900's a pitching wedge was referred to as a lofter and had between 40 and 50 degrees of loft. Shortly thereafter, sets of golf clubs were given numbers, and the modern-day pitching wedge was called a 10-iron. Now a set of irons will include a pitching wedge with a loft of between 45 and 48 degrees.
