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.
Distance. Men typically hit their pitching wedge from 100 to 140 yards, depending on their skill level, while women hit the same club from 70 to 120 yards. Beginners often find they do not achieve these distances, but their distances will increase as their swing improves.
