View Patent ↗Golf clubs and/or golf club heads include a club head body defining an interior chamber, structure for engaging a shaft with the body, and/or a shaft engaged with the body. The club head body may have an overall length of at least 4.5 inches and an overall breadth of at least 4.2 inches. In other examples, the club head body may have an overall length of at least 4.6 inches and a ratio of the overall breadth dimension to the overall length dimension of 1 or less. If desired, the ratio of the head breadth to head length dimensions may be in a range from at least 0.94 to 1 or less.
