Explanation of Bounce on Wedges
Golfers generally know that the loft of a club helps get the ball in the air. But bounce is the angle of the sole against the ground at address, is just as important to a good golf shot as loft. The higher the degree of bounce to a club, the better it runs over the ground rather than cutting into it. Like loft, the bounce of a club is measured in degrees and wedges have higher bounce than long irons.

Selecting proper bounce depends on a players swing style and the average course conditions that they play on.
Low Bounce

Clubs with bounce of less than 8 degrees are considered “low bounce” wedges, Lob, pitching and gap wedges usually have the lowest bounce of all wedges, making them a good selection for tight lies, wet sand and hard turf. Low bounce translates into less opportunity for hitting a shot thin, as the sole of the club should sweep over the surface, rather than cut into it. In general, lob wedges have 0 to 10 degrees of bounce, pitching wedges have 2 to 5 degrees of bounce and gap wedges have 5 to 12 degrees of bounce.

High Bounce

Clubs with a bounce of more than 10 degrees are considered “high bounce” wedges. Sand wedges and some specialty gap wedges usually have high bounce, making them a good choice for light sand, deep rough or a shaggy fairway. Because the angle of the swing will be steeper, the high bounce allows the club to slide over the surface and create the opportunity not only for clean impact, but also height on the shot. Sand wedges have the most amount of bounce of any wedge, usually between 10 and 16 degrees. Specialty gap wedges may have as much as 12 degrees of bounce, though most are lower.

Selecting proper bounce depends on a players swing style and the average course conditions that they play on.
