How to Size Golf Clubs for a Teenager

By Spencer Lanoue
July 24, 2025

Finding the right size golf clubs for a teenager is one of the most impactful things you can do for their game. Get it right, and you set them up for a future of consistent, powerful swings. Get it wrong, and you can bake in bad habits that are tough to fix later. This guide will walk you through exactly how to determine the right fit, covering everything from simple home measurements to the key specs that truly make a difference, helping you make a confident and smart decision.

Why a Proper Fit Is So Important for Teen Golfers

Unlike adults who have stopped growing, a teenager is a moving target. They are in a constant state of flux—growing taller and stronger, often in unpredictable spurts. This presents a unique challenge when it comes to golf equipment. A set of clubs that fits perfectly in April might be too short by August.

This is more than just a minor inconvenience. Playing with ill-fitting clubs, particularly those that are too short, forces a young golfer to make unnatural compensations in their swing. They might stand too hunched over or develop a swing that is overly steep and reliant on their hands and arms instead of the powerful rotation of their body. These compensations quickly become ingrained as muscle memory. A few months later, even after they get clubs that fit correctly, that faulty swing motion can frustratingly remain.

A properly fitted set of clubs does three things for a teenage golfer:

  • Promotes a Solid Foundation: It allows them to stand in an athletic, balanced posture and swing the club on the correct plane, developing technically sound fundamentals from the start.
  • Builds Confidence: When the club is doing what it's supposed to do, hitting the sweet spot becomes easier. Good shots feel great, building the confidence and enjoyment needed to stick with a challenging game.
  • Prevents Injury: Contorting your body to accommodate poorly sized equipment can put unnecessary strain on the back, wrists, and shoulders. A proper fit encourages a natural, flowing motion that is both safer and more powerful.

Two Paths to Finding the Right Set: Off-the-Rack vs. a Fitting

When it comes to sourcing clubs for a teen, you generally have two options: buying a pre-packaged "teen" set or going through a club fitting process. Neither is inherently better; the right choice depends on the teenager's age, size, and commitment to the game.

Option 1: Boxed Teen Sets

Many major manufacturers offer boxed sets designed for golfers who have outgrown junior clubs but aren't quite ready for a full-sized adult set. These are a fantastic option for a few reasons:

  • They are sized appropriately. They typically feature slightly shorter shafts and lighter clubheads than standard men's or women's clubs.
  • The specs are beginner-friendly. The shafts will be more flexible (helping to generate clubhead speed) and the grips will be standard or undersized, fitting smaller hands better.
  • It's cost-effective. They provide a complete, ready-to-play set at a much lower price point than buying individual clubs.

A boxed teen set is often the perfect solution for a younger teen (13-15) who is just starting out or plays golf more casually. It gets them on the course with equipment that isn't actively working against them. The main downside is the lack of customization. If your teen is unusually tall or short for their age, or if they are a highly competitive player, a boxed set might not be precise enough.

Option 2: A Club Fitting

A club fitting involves working with a professional fitter or coach to analyze a teen’s body type and swing to determine the exact specifications they need. This process allows you to customize individual components like shaft length, lie angle, shaft flex, and grip size.

This doesn't mean you have to buy a brand-new, expensive set. A fitting can be as simple as a 30-minute session with a local pro to find the right length and lie angle for a used set of irons you found online. Or, it can be a comprehensive process using launch monitors to build a custom set from the ground up.

A fitting is the recommended path for:

  • Teens who are serious about improving and play competitively.
  • Older teens (16-18) who are nearing their full adult height.
  • Any teen whose body shape deviates significantly from the average (e.g., very long arms or vice-versa).

Key Measurements You Can Take at Home

Whether you're looking at a boxed set or preparing for a fitting, having two key measurements will give you a massive head start. These static measurements are the foundation of club fitting and are easy to take at home.

1. Overall Height

This is the most basic starting point. Teen club sets are often sold based on height ranges, so knowing your teen's exact height is essential. Simply have them stand tall against a wall and measure. While it's a good guide, don't rely on height alone, because it doesn't account for arm length—which is where our next measurement becomes even more important.

2. Wrist-to-Floor Measurement (WTF)

This is arguably the most valuable measurement for determining the correct club length and lie angle. It accounts for how a person’s arm length relates to their height, providing a much more accurate recommendation. Two people can be the same height, but if one has longer arms, they will likely need a shorter or flatter club.

How to take the Wrist-to-Floor Measurement:

  1. Have the teenager stand upright on a hard floor, wearing their normal golf or athletic shoes.
  2. Their shoulders should be relaxed, with their arms hanging naturally at their sides. They shouldn't be stiff or reaching down.
  3. Using a tape measure, measure the distance from the floor to the crease of their wrist (where their hand hinges forward). It's best to take the measurement for their lead hand (the left wrist for a right-handed golfer).

Once you have this "WTF" number, you can consult a fitting chart (readily available online from major club manufacturers) to see their recommended iron length and lie angle. This data is incredibly powerful for guiding your purchase or your conversation with a club fitter.

Beyond the Basics: Specs That Make a Big Impact

Once you have length figured out, a few other specifications can dial in performance.

Shaft Flex and Weight

A teenager is still developing their swing speed. For this reason, it’s almost always better to err on the side of a shaft that is lighter and more flexible. A heavy, stiff shaft will feel like swinging a steel pipe and rob them of both speed and feel. Lighter shafts in "Regular," "Senior," or "Ladies" flex are often a perfect match, allowing the teen to load the club properly and generate effortless power. As they get stronger and faster, they can transition to stiffer shafts.

Grip Size

Getting the grip size right gives a golfer better control of the clubface. A grip that's too small might encourage too much hand action, leading to hooks. A grip that's too large can restrict the hands and cause pushes or slices. A simple home check is to have the teen grip a club; the fingertips of their lead hand (left for a righty) should just barely touch the palm. If there’s a gap, the grip is too big. If the fingers dig in deeply, it's too small.

The Magic of Adjustability

Many modern drivers, fairway woods, and hybrids feature adjustable hosels. This is a game-changer for teenage golfers. These adjustments allow you to change the loft and lie angle of the club with a simple wrench. As a teen grows or their swing changes, you can adapt the club to them instead of having to buy a whole new one. Prioritizing adjustable clubs can save a lot of money and headaches over time.

Final Thoughts

Sizing golf clubs for a teenager is all about striking a balance. You want a set that fits them well right now to promote sound fundamentals, while also keeping an eye on their inevitable growth. By taking a few simple measurements and understanding the key specifications like shaft flex and grip size, you can make a very informed choice that puts them in a great position to succeed and love the game.
