The short answer is yes. Under the current Rules of Golf, a golfer can touch the line of his putt on the putting green. The old blanket prohibition was removed in 2019. But there is one big condition: you cannot improve the surface. If your touch changes the line in any way that could affect how your golf ball rolls, you break the rule.
I have seen many players assume any contact is a penalty, and I have seen others go too far by pressing down spike marks. This article gives you the full picture so you never have to guess again.
What the New Rule Says
Rule 8.1b now explicitly allows a player or caddie to merely touch the putting green on the line of play (the old term “line of putt” is no longer used). You can touch it with your hand, your putter, your towel, or even accidentally with your foot. The key word is “merely.” As long as you do not improve the surface, you are fine.
The old rule had seven exceptions that made it confusing. The USGA and R&A decided that touching the line without gaining an advantage should not be penalized. That change simplified the game for everyone.
Understanding the Touch-Improvement Spectrum
The biggest confusion golfers face is where “touching” ends and “improving” begins. I think of it as a spectrum. On one end, you have actions that change nothing. On the other end, you have actions that physically alter the grass or soil.
Allowed touches:
- Lightly brushing away a loose leaf or bit of mud with your hand
- Resting your putter head on the surface behind the ball without pressing
- Accidentally stepping on your line with your normal walking stride
- Your caddie is dragging the flagstick across the line
Borderline – not recommended:
- Rolling a ball across the line to remove dew or water (this can be seen as testing the surface)
- Using your putter to tap down a spike mark that is already raised (any downward pressure is improvement)
Prohibited improvements:
- Pressing down a spike mark or depression
- Smoothing out a bump or tuft with your shoe or towel
- Dragging a towel over the line to flatten the grass
- Using your hand to push down a patch of torn turf
The rule is clear: if your action could make the ball roll straighter or alter the surface even slightly, it is an improvement. The penalty for that is two strokes in stroke play or a loss of a hole in match play.
Allowed Touches vs. Prohibited Improvements | A Quick Comparison
| Action | Allowed? | Why |
|---|---|---|
| Brushing away a leaf with your hand | Yes | No surface change |
| Grounding putter behind the ball (no pressing) | Yes | Mere touch |
| Stepping on the line while walking | Yes | Accidental, no improvement |
| Pressing down a spike mark with your putter | No | Improves the surface |
| Dragging a towel to flatten a tuft | No | Alters the line |
| Using your foot to smooth a depression | No | Direct improvement |
Common Scenarios in the Course
Let me walk you through real situations I have faced and seen others face.
You accidentally step on your line. Fine. No penalty. The rule allows incidental contact because it gives no advantage. But if you then try to fix the footprint you created, that is an improvement. You can repair ball marks, old hole plugs, and other damage, but you cannot lift or press down a footprint you just made. Let it be.
Your caddie drags the flagstick across your line. Allowed. Under the new rule, that counts as a mere touch. Unless the flagstick had mud or debris that leaves a mark that changes the surface. In that case, you could be judged as improving the line even if it was accidental. Best practice: Clean the flagstick before removing it.
You want to wipe the dew off your line with a towel. Dew is not part of the surface. Wiping it off is allowed. But pressing the towel down to flatten the grass is not. Light swipe only.
You touch the line with your fingers to feel the grain or moisture. This is allowed as long as you do not press. Lightly feeling the texture helps you read the putt, and the rule recognizes that as a legitimate use of touch. Testing the green by rolling a ball is still prohibited, but touching with your hand is fine.
Your putter head rests on the line before you take your stance. Perfectly legal. In the old rules, grounding the putter on the line could be a penalty if you were measuring or pressing. Now, simply placing the putter head on the surface is allowed. I often tell my playing partners, ” Go ahead and set the putter down, just don’t dig in.
What About Accidental Contact?
Accidental contact is almost always allowed because the rule says “merely touching” includes unintentional touch. I have had a playing partner trip and step right on my line. No penalty.
The key is whether the contact changed the surface. If it did, even accidentally, you may be subject to the rule. But officials usually look for intent. An accidental spike mark that leaves a depression? You are not penalized unless you then try to smooth it. So don’t panic – just play on.
Why Did the Rule Change?
Before 2019, the rule against touching the line of putt had so many exceptions that it was hard to enforce. You could fix ball marks, repair old hole plugs, remove loose impediments, and so on, but you could not touch the line for any other reason.
That led to silly penalties. I remember a professional being penalized because his caddie accidentally touched the line with the flagstick. The new rule stops those unnecessary punishments.
The governing bodies also realized that merely touching the line gives no advantage. You cannot improve the roll of a putt by lightly brushing a leaf or stepping on the grass. So they eliminated the blanket ban and kept only the improvement prohibition. That change made the game simpler and fairer.
Two Common Myths Busted
Myth 1: You cannot touch the line at all on the green.
This was true before 2019. Today, you can touch it freely as long as you do not improve the surface. Many golfers still carry the old rule in their heads. I have corrected players in my group who apologized for stepping near my line. No need.
Myth 2: Touching the line with your putter is always a penalty.
Not true. Grounding your golf putter behind the ball – which sits on your line – is allowed. The old rule treated that as a penalty in some cases (like when the ball was off the green). Now, on the putting green, you can set the club down. What you cannot do is press down or smooth the grass.
Frequently Asked Questions
Can I use my foot to smooth out a spike mark on my line?
No. That counts as improving the surface. You may only touch – not alter.
If I accidentally touch the line with the towel while wiping my ball, is that a penalty?
Generally, no, as long as the towel does not change the surface. Accidental contact is covered under “merely touching.”
Does the rule apply to the fringe or apron just off the green?
No. The new touching allowance applies only to the putting green. On the fringe, Rule 8.1a still prohibits improving your line of play. So do not touch your line there.
What about testing the surface by touching the line with my fingers before putting?
Lightly feeling the texture is allowed. But if you press down, that becomes an improvement. Testing the green by rolling a ball is still prohibited.
My caddie dragged the flagstick across my line – is that a problem?
Under the new rule, it is allowed as a “mere touch.” However, if the flagstick had mud that left a mark or changed the surface, it could be judged as an improvement. Intent matters – accidental drag is typically no penalty.
If you take away one thing from this article, let it be this: the rules now trust you to touch your line without gaining an advantage. The only line you must not cross is improvement. Know the difference, and you will never have to worry about a penalty for a simple touch.
