What Causes Thin Golf Shots?

By Spencer Lanoue
July 24, 2025

Nothing sours a great drive faster than following it up with a screamingly low, thin iron shot that scythes across the fairway and rockets over the green. It’s a frustrating, power-sapping mistake, and it feels like a total waste of a good swing. If you’re tired of that skulling sensation and the unpredictable results it produces, you’re in the right place. This guide will walk you through the real reasons thin shots happen and give you straightforward, actionable steps to start striking your irons pure.

What Exactly IS a Thin Shot? A Quick Refresher

Before we can fix it, we need to agree on what it is. A thin shot (also called a "skulled" or "bladed" shot) happens when the leading edge of your golf club makes contact with the golf ball at or above its equator. Instead of compressing the ball against the clubface with a downward strike, you're essentially clipping it on the top half.

The result?

  • Minimal backspin, so the ball doesn't rise.
  • A low, powerful, and often uncontrollable trajectory.
  • A harsh, clicky sound at impact.
  • A total lack of a divot, or maybe just a short scuff on the turf well ahead of where the ball was.

The goal with an iron shot is the opposite: you want a ball-first, then turf contact. The club should be traveling on a shallow, downward path as it strikes the ball, compressing it and taking a divot just after the ball’s position. This is the secret to those satisfying, high-launching, soft-landing iron shots you see the pros hit.

Cause #1: Losing Your Posture (Early Extension)

This is arguably the most common cause of thin shots among amateur golfers. It happens when your hips drive forward towards the golf ball and your upper body stands up during the downswing. You start your swing in a good athletic posture, bent over from the hips, but as you approach impact, you straighten up.

When you stand up, your entire swing arc rises with you. The low point of your swing, which should be slightly in front of the ball, lifts up several inches. If it lifts enough, the leading edge of the club comes up and smacks the middle of the ball. It’s your body’s subconscious attempt to create power or help "lift" the ball, but it does the exact opposite.

The Fix: Maintain Your Spine Angle

You need to learn the feeling of rotating your body while staying in your golf posture. It’s a rotational movement, not an up-and-down one. Here are a couple of drills to engrain this feeling:

Drill 1: The Chair Tuck

1. Set up without a club, with your backside lightly touching the front edge of a dining chair or your golf bag.

2. Perform slow-motion practice swings. Your goal is to keep your backside in contact with the chair throughout the entire swing, from backswing to follow-through.

3. As you rotate back, your left glute will press into the chair. As you rotate through, your hips will turn, and your right glute will brush against it.

4. If you stand up (early extend), you'll immediately feel your back end pull away from the chair. This provides instant feedback that you’ve lost your posture.

Drill 2: The Head against the Wall

1. Stand in your golf posture a few inches away from a wall, so that the top of your head is lightly touching it.

2. Practice your backswing rotation. It will force you to turn your shoulders on a flatter plane, keeping your head steady.

3. Now for the downswing. As you rotate your hips and shoulders through, focus on keeping your head in contact with the wall for as long as possible. You should feel your body unwinding underneath a stable head position.

4. This prevents you from lifting your upper body, which is a key contributor to thinned shots.

Cause #2: Trying to Scoop or 'Help' the Ball into the Air

This is a mental mistake that has very real physical consequences. Many golfers see the ball sitting on the ground and feel an instinctual need to get under it to help it launch. This "scooping" motion involves flipping your wrists at the ball, breaking down the nice angle you created between your lead arm and the club shaft.

When you do this, the clubhead passes your hands too early. The swing’s low point moves behind the ball, and by the time the club actually reaches the ball, it's already on an upward path. The result is a perfect recipe for a thin strike.

The Fix: Trust the Loft and Hit Down

Your golf clubs are designed to get the ball in the air. A 7-iron has about 30-34 degrees of built-in loft for that very reason. Your job isn't to lift the ball, it's to deliver that loft to the back of the ball with a downward blow. Hitting down is what makes the ball go up.

Drill: The Towel Drill

1. Take a small hand towel and place it flat on the ground a few inches - about the length of a dollar bill - behind your golf ball.

2. Set up to the golf ball as you normally would.

3. Your goal is simple: hit the golf ball without hitting the towel. That's it.

4. To accomplish this, you will have no choice but to create a downward angle of attack. Any scooping motion or early release of the wrists will cause you to hit the towel first. This drill forces you to move your swing's low point in front of the ball, which is the key to pure contact and eliminating thin shots.

Cause #3: Improper Weight Shift (Swaying)

Proper weight shift is a subtle but critical part of the golf swing. Many amateurs, however, misinterpret "shifting weight" as "swaying." They slide their entire body too far away from the target on the backswing, then slide it too far toward the target on the downswing. The problem with swaying is that the low point of your swing becomes a moving target. It makes consistent contact nearly impossible.

A common fault is the "reverse pivot," where a player leans toward the target on the backswing and hangs back on their trail foot during the downswing. As they hang back, their upper body tries to compensate by lunging at the ball, but they can't get their weight forward. This leaves the low point behind the ball, causing them to catch it on the upswing - a classic thin.

The Fix: Rotate Around a Stable Center

The feeling you want is one of rotation. Think of yourself swinging inside a barrel or cylinder. You want to turn within the confines of that cylinder, not crash into the sides of it.

Drill: The 'Stay in Your Cylinder' Feel

1. Set up and imagine those cylinder walls I mentioned just outside your feet.

2. On your backswing, feel the pressure build on the inside of your trail foot (your right foot for a right-handed golfer). If you feel weight shifting to the outside of your foot, you are swaying, not rotating.

3. As you begin your downswing, the first move is a slight shift of pressure to your lead foot. Think of it as pushing off the inside of your trail foot to initiate the turn.

4. From there, your main thought should be to unwind and turn your torso through the shot. This rotational motion, combined with a proper weight shift, will keep your swing centered and allow you to consistently find the low point in font of the ball.

Cause #4: Incorrect Ball Position

Sometimes the solution is a lot simpler. If your swing is fundamentally sound, a series of thin shots might just be coming from a setup flaw. Ball position determines where the club is in its arc when it meets the ball.

If the ball is placed too far forward in your stance for your iron, the club will have already passed the lowest point of its arc and started rising by the time it gets to the ball. Even with a good swing, this will produce a thin contact.

The Fix: A Simple Ball Position Guide

You don't need to overcomplicate this. A great rule of thumb for amateurs is:

  • Wedges, 9-iron, 8-iron: Place the ball directly in the middle of your stance. Imagine a line running from the ball up to the center of your chest or your shirt buttons.
  • 7-iron, 6-iron, 5-iron: Move the ball position just slightly forward of center - maybe one golf ball's width inside your lead heel.
  • Longer irons, hybrids, and fairway woods: Continue this gradual progression forward, with your driver being the furthest forward, played off your lead heel.

Adjusting your ball position is a quick check you can make on the course or range. If you feel like your swing is fine but you're blading everything, take a moment to look down and make sure the ball isn’t creeping too far forward.

Final Thoughts

Eliminating thin shots boils down to understanding the cause and effect of your swing movements. In most cases, it's about learning to maintain your posture through extension, letting the club's loft do the work with a downward strike, and rotating properly instead of swaying off the ball. Focus on these movements and you’ll leave those frustrating thin shots behind.
