Golf Club Specs: Hosel Offset
In golf club terminology, offset occurs when the leading edge of the clubface is placed behind the hosel’s leading edge, as shown in the diagram below. An offset head gives the golfer a fraction of a second longer to square up the clubface at impact, which aids in the reduction of slicing. Conversely, a golfer who already squares the clubface properly may find that using offset heads leads to an overly closed face at impact and a tendency to hook the ball.
Golf club offset is typically measured relative to the width of the shaft, with common terms being “half-shaft” and “full-shaft” offsets. While all clubtypes can exhibit offset, it is uncommon for any club except putters to have more than one full-shaft of offset. Offset is more common and more pronounced in game-improvement or oversize clubheads than it is in traditional or blade-style heads.
