Pitching wedges have a loft of between 46 and 48 degrees. Approach wedges have lofts between 50 and 52 degrees. The extra loft on the approach wedge helps it to get up in the air, but decreases the distance hit.
First, figure out how far you can hit your pitching wedge with a comfortable full swing. For an example, letâs say that number is 110 yards, from there, you want to make sure your next wedge in line will fly around 95 yards. A 52 degree wedge is a popular choice, but 54 degrees could work as well.
