Symptom
Uphill putts come up short, downhill putts run away
Flat putts finish about the right length, but uphill putts die well short of the hole and downhill putts race past it or bend far more than you played for.
This usually traces to something already true before the club moves: grip, aim, posture, or where the ball sits in your stance. All of those are checkable standing still, which is why the questions ask you to look rather than to guess.
Common ways golfers describe this
Downhill putts always run past
Scared of downhill putts
Hit downhill putts off the toe
Downhill putts break more
How much break on a downhill putt?
- Feet, in the footprints: square to the line
- Hips, cross ticks: square to the line
- Shoulders, round ends: square to the line
- Target line
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
- Which sloping putts go wrong, and what does the ball do?
- Take one putt across a slope. Do you play a different amount of break going downhill than you would going uphill?
- On a quick downhill putt, what do you actually do to take pace off it?
- On a downhill putt, what does the ball do in the first foot after it leaves the face?
- Mark the putter face and roll ten putts on a slope, half up and half down. Where do the marks sit?
- What do you do on a sloping putt that you would not do on a flat one?
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.
Break not matched to the pace
Slope acts on a ball for as long as it keeps rolling, so the same putt takes more break when it is rolled softly and less when it is firm. Reading a line without deciding a pace, or hitting a different pace than the read assumed, misses on either side.

Deceleration into impact
The club slows down before it reaches the ball, almost always after a backswing longer than the shot required. Speed disappears at the only moment it matters, and the bottom of the arc becomes unpredictable, which is why decelerating produces both the chunk and the blade.
Read the fix
Off-centre strike on the putter face
Contact away from the centre transfers less energy, so strokes that felt identical finish different distances. It also twists the face slightly at impact, which moves the start line as well as the pace.
Read the fix
Putting low point in the wrong place
The stroke bottoms out behind the ball and drives it down into the turf, or catches it above centre on the way up. Either way the ball hops and skids before it begins rolling, which costs distance and sends it offline on the bounce.
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.

Related symptoms
These are not here because they sound similar. Each one can come from a cause on the list above, which is why fixing one sometimes quietly fixes another. The closest matches are first.
- I can't putt on grainy greensOn Bermuda or other grainy greens, putts into the grain pull up short, putts down the grain run past, and the ball bends in ways the slope on its own does not explain.Shares break not matched to the pace
- Three-putting too oftenToo many greens take three putts or more, usually because the first putt leaves a second that is longer or harder than it should be.Shares deceleration into impact
- No distance control on the greensLong putts finish well short or well past the hole, so the first putt seldom leaves you a tap-in.Shares deceleration into impact
