Bounce and grind: the wedge variables loft can't decide

Bounce is the angle the sole hangs below the leading edge, and it works as the wedge's shock absorber. Practitioners sort it into three bands: low is 4 to 6°, mid is 7 to 10°, high is 10° and up. Steep, divot-taking deliveries need high bounce to keep the club from digging; shallow sweepers need low bounce so the leading edge stays playable. Get it backwards and you either bounce the club into the ball's equator or dig a trench.

Turf and sand both vote, and they can vote differently. On turf, firm links ground wants low bounce, around 0 to 10°, medium turf sits happiest in the 7-to-10° range, and soft parkland asks for 10 to 16° and up. Sand is its own axis: fluffy bunker sand wants high bounce, roughly 12 to 14°, on a wide sole that skids rather than digs, while firm, wet, or coarse sand rejects a fat sole and prefers something lower and narrower so the leading edge can slip under the ball. If you need one number to start from, a versatile 12° sand wedge fits more golfers than anything else.

The stamped bounce is not the whole sole, either. Width and camber matter, and they track loosely with skill: tour-style soles run narrow, about 0.75 to 0.9 inch, mid-handicap soles widen to roughly 1.0 to 1.4 inch, and maximum-forgiveness soles reach 1.8 to 2.0. A wider sole plays like more effective bounce than its stamped number, though that comparison is a rule of thumb rather than a measured degree count. Camber, the front-to-back curve of the sole, smooths entry for shallow deliveries.

Grind is where the sole gets sculpted, and Vokey's own lettering is a clean way to read it. F is a full sole for square-faced full shots; S adds a little trailing-edge relief; M cuts heavy heel, toe, and trailing relief for players who open and rotate the face; D pairs a high-bounce front with relief for steep, aggressive deliveries; K is the widest, highest-camber sole for maximum bunker forgiveness and comes in a firmer 06 and a softer 12; L is a narrow crescent with low bounce for firm turf and skilled face-openers. Other brands use their own vocabularies for the same ideas. The through-line: face-openers and shot-makers want heel-and-toe relief, while square-face pitchers and bunker players want a fuller, wider sole.

One design cousin worth a mention: full-face or high-toe wedges extend the grooves up and toward the toe for players who open the face and hit from rough, where strikes migrate high on the blade. They keep more grooves in play; they do not add raw spin. One honest limit ties all of it together: bounce has no published spin or yardage number attached, because it is a digging-versus-thinning decision rather than a distance lever. Numbers alone cannot finish this fitting, since divot depth, turf, and sand are things we can ask about but not see. Get the lofts right from your gapping, describe your delivery honestly to set the sole, and verify on turf if you can.
