Planning Club Length Around a Growth Spurt

Filed under: JuniorsSunday programmeAbout 6 minutes

Parents arrive at the Sunday sizing session with one of two problems. Either the clubs are obviously too short and the child has been chopping at the ball for a season, or the clubs are obviously too long because somebody bought ahead and the child has spent a year learning to compensate for a club they cannot control.

Both problems come from the same place: treating a junior set as a purchase rather than as a plan.

Growth Is Faster Than Golf Budgets

Between ages nine and fifteen, a child can add two to four inches of height in twelve months, and the growth is rarely evenly distributed. Legs often lengthen before torso, which changes wrist-to-floor measurement faster than it changes standing height — and wrist-to-floor is the number that actually sets club length.

A club length that is correct in spring can be genuinely wrong by autumn. Nobody is going to buy two sets a year, so the question becomes how to make one set cover a moving target.

Build From a Chassis, Not a Box

Our answer is to start from adult or teen component heads with reasonably light shafts and cut them down to the child's current measurement, leaving the option to re-shaft or extend later. That sounds more expensive than a boxed junior set and often is not, because the same chassis survives three or four re-sizes.

Boxed junior sets are built to a price and to a height bracket. Once the child leaves the bracket, the whole set gets replaced. A cut-down chassis gets re-trimmed, re-gripped, and handed back for about the cost of a couple of lessons.

The set should be able to grow twice before it needs replacing. If it cannot, it was the wrong purchase regardless of what it cost.

The Numbers We Take

Junior sizing takes forty-five minutes and starts with measurements taken barefoot against a wall, because shoes and posture both distort the reading and a fidgeting eleven-year-old distorts it further.

• Standing height, barefoot, heels flat against the wall
• Wrist-to-floor with arms hanging relaxed, taken twice
• Hand span across the palm, for grip core selection
• A short swing look to judge whether they can control current mass
• A note of which clubs they actually use on the course

All five go on a card written for the parent rather than the child, along with a target height that triggers the next visit. That last line is the most useful thing on the page: "bring these back when she reaches 4 ft 11 in" is a far more actionable instruction than "come back next year".

Mass Matters More Than Length

Length gets the attention because it is visible. Mass is the spec that ruins more junior golfers, because a club too heavy for a child forces a swing that hauls rather than swings, and that habit outlasts the club by years.

A nine-year-old should be swinging something in the region of 250 to 280 grams total club mass. Plenty of cheap junior sets ship well above that because heavier steel is cheaper than lighter graphite. If a child's swing looks like a heave, check the scale before you check the coaching.

Do Not Fit for the Adult Swing They Might Have

The temptation with a talented junior is to fit toward what they will need in three years. Resist it. A club they can control today produces good contact today, and good contact is what keeps a child interested long enough to still be playing in three years.

Length in particular should never be bought ahead. An inch of extra length on a junior club moves the strike toward the heel and teaches a compensation that has to be unlearned later.

What a Sensible Four-Year Plan Looks Like

Age ten: cut-down chassis, seven clubs, light graphite, sized to current wrist-to-floor. Age eleven: re-trim to the new measurement, forty minutes, half the original fee. Age twelve: growth spurt, extend or re-shaft, add a wedge and possibly a hybrid. Age thirteen or fourteen: the chassis is at the end of its adjustment range and a proper teen set is worth buying — fitted properly, with a card, because by then they are close to adult specs.

Four sizings and one real set, spread over four years, against three complete boxed sets in the same period. It is cheaper, and every step of it is written down so nobody has to remember what the last one measured.
