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.
Loft of Approach Wedge. The approach wedge has a loft of 50 to 54 degrees. It has more loft than a pitching wedge and less loft than a lob wedge. It is used on short shots to the green when the golfer wants to hit the ball high and land it softly. The approach wedge can be used on shots from 50 to 80 yards.
