The most important part of starting young golfers out correctly is making sure they are properly fitted for their golf equipment. The proper fit affects everything from being able to swing the club the right way to their enjoyment of the game.
Ensure that kids are correctly fitted for clubs by going to a professional club fitter. Most golf stores and golf courses have golf professionals or employees who are trained to fit youngsters with equipment that's suited to their size and skill level.
Choose clubs that are the correct length and weight. This not only plays a role in the future development of young players, but it also allows them to have fun while learning the game. Good-fitting clubs lead to good golf shots, whereas clubs that are improperly fitted make it impossible for kids to hit good shots.
Don't worry about brand names. Purchase clubs that correctly fit the physical development of the child. Understand that because kids grow quickly, their golf clubs will need to be replaced every year or so while they are growing. There is nothing wrong with purchasing used junior clubs you find at a Goodwill store or garage sale---just make sure they fit properly. Most golf stores have fitting charts for junior players. Just measure your son or daughter, write down the specifications and save the information for when you need it.
Don't cut down full-length golf clubs for kids. These modified clubs are too heavy, and the shafts are too stiff for kids to properly swing them, which will make learning the game harder than it already is. It's much better to purchase two or three clubs that fit properly than to give your kids ill-fitting equipment.
Allow your kids to start out being able to swing their clubs in the correct way by having clubs that fit them properly. If you choose to have them take lessons (which is strongly recommended), they have a better chance to accomplish what their instructors are teaching them. The more good shots kids hit, the more they will enjoy the game. And it all starts with having clubs that fit!
