Symptom
Perfect practice swing, bad real swing
The practice swing brushes the turf in the right place and finishes balanced, but with a ball in front of you the strike turns fat, thin or topped.
Fat, thin and topped shots are one problem seen from different sides: the lowest point of the swing arc is not where the ball is. Where it sits instead, and why, is what separates the causes below.

Narrow it to one cause
Each question is here because golfers answer it differently, and that difference is what rules a cause out. Nothing is generated while you answer: every question, cause and fix was written and checked in advance.
A few questions · no account needed
What you will be asked
- Make three practice swings beside the ball and let the club brush the grass. Where is that brush mark compared with where the ball is sitting?
- With the ball there, what does the real swing do?
- Once you are standing over the ball, what are you actually trying to do that you were not trying to do in the rehearsal?
- Compared with the practice swing, how does the real one feel from the top?
- Squeeze the grip as hard as you can and call that ten. What number are you holding it at in the rehearsal, and what number over the ball?
- After the practice swing, how do you get from there to the ball?
Where this can come from
These are the causes this symptom resolves to, in the order they turn up most often. That order is not a diagnosis and it is not your answer: two of them can produce a shot that looks identical from behind. Each has a fix you can read now, whether or not you answer anything.
Trying to lift the ball into the air
An instinct to scoop the ball upward adds loft through impact and moves the low point behind the ball. Height comes from the loft already built into the club and from a descending strike, so the attempt to help the ball up produces the opposite: a thin or topped shot that never climbs.

Casting, or releasing the club too early
The wrist angle is thrown away at the start of the downswing, so the shaft arrives vertical or leaning backwards. That adds loft, moves the low point behind the ball, and widens the arc early, which is why casting costs distance and drops the strike low on the face at the same time.

Weight hanging on the trail foot
Pressure stays on the trail foot through impact instead of moving toward the target. The low point of the arc sits behind the ball, so the club either bottoms out early and takes turf first, or is travelling upward by the time it arrives. Both misses come from the same cause, which is why fat and thin so often alternate.
Read the fix
No repeatable setup or routine
Aim, ball position, stance width and grip get rebuilt slightly differently on every shot, so face angle, low point and strike location all vary with them. Address is the reference the whole swing is measured from, and a reference that moves explains misses that seem to have no pattern.
Read the fix
Grip pressure too tight
Holding the club hard enough to tense the hands and forearms makes the delivered face angle less repeatable and shortens the motion. It is the most common physical expression of pressure, which is why the same golfer strikes it well on the range and loses the face on the first tee.
Read the fix
Ball too far forward in the stance
The ball sits ahead of where the swing arc reaches its lowest point. With an iron off turf this means the club is already climbing at contact. It also encourages the shoulders to aim left at address, which pulls the path further left and adds curve to the miss.
