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.
Lofts for clubs are typically 45 to 48 degrees for a Pitching wedge, 50 to 54 for a Gap Wedge, 54 to 58 for a Sand Wedge (although 56 is very common). Gap wedges have a rather wide range, but typically range from 50 to 54 degrees. In the lower range, from 46 to 50, a wedge typically has no flange on the bottom--that is, no bounce.. It is often called an approach wedge and is sometimes labeled A..
