Rules Guy: When measuring a club-length, is it legal to leave the headcover on?
Rules Guy tackles a common question about measuring drops: can you leave your headcover on your club? Find out what the Rules of Golf say about this nuanced situation.

The Rules of Golf can be tricky! Thankfully, we’ve got the guru. Our Rules Guy knows the book front to back. Got a question? He’s got all the answers.
During the Masters, Sam Burns took a penalty drop from Rae’s Creek. He measured two club-lengths from the agreed point of entry with his driver…but left the headcover on! He did the same playing with Matthew Fitzpatrick when Fitzpatrick won the U.S. Open. Is this legitimate? – Alan Absolon, via email
That depends — was the headcover a cute one? Like, in the shape of an animal, or with a pom-pom? We kid.
As long as the ball ends up in the right spot, the Rules don’t really care how you measure. Unless a player is trying to use the extra length of the headcover and drops at the very end of the two club-lengths-plus-headcover, it doesn’t matter in the least whether the headcover stays on or not.
So long as you drop within the two club-length distance sans headcover, it’s fine. See, yes, “Definition of Club-Length.”
More Guidance on Measuring Club-Length
In another rules-related scenario, a player inquired about leaving their club-length marker on the ground while taking relief under the preferred lies local rule.
Due to rain, our club decided to use preferred lies during the club championship. On the 4th hole, a competitor took the one club-length relief allowed under the Local Rule for preferred lies, then claimed relief from a cart path that now interfered with his stance. His original lie was behind a tree, and the relief provided him a clearer path to the green. Was he clever or all wet? – Paul Hinz, Sartell, Minn.
Paul, this is precisely why the Rules recommend that preferred lies not be used in the entire general area and instead be limited just to parts of the general area cut to fairway height or less — otherwise, there is definite potential for a player to sashay out of golf jail.
If the Committee indeed enacted the Local Rule in the entire general area, once the player uses his free club-length and then has interference from an abnormal course condition such as a cart path, he would be allowed to take relief under Rule 16.1b.
Once finished doing so, he could then prefer his lie under the Local Rule again if so desired. We thus prefer that the Local Rule be done in the recommended fashion.
The Importance of Precise Rule Adherence
The Rules of Golf, governed by the R&A and USGA, are designed to ensure fair and consistent play for everyone. Understanding nuances like measuring club-length can prevent unintentional penalties and maintain the integrity of the game.
Club-length is typically measured from the ground up to the top of the grip. However, as the headcover example illustrates, the Rules allow for some flexibility as long as the core requirement – not gaining an unfair advantage – is met. In Sam Burns' case, if he did not use the headcover to extend the total measured distance, his actions were likely legal, as he remained within the permitted two club-lengths from his drop point.
What Constitutes 'Club-Length' in the Rules of Golf?
According to the Rules of Golf, 'club-length' is defined as the length of any club a player may use for measurement. A player can choose any club from their bag to measure with. This means you could use a driver, an iron, or even a putter. The key is that the chosen club must be part of the player's conforming set they have with them during play.
When is Club-Length Measurement Applied?
Club-length measurement is most commonly used when taking a drop (re-dropping a ball) after obtaining relief from various types of interference, such as:
- Abnormal Course Conditions (Rule 16.1): such as casual water, temporary water, animal holes, or ground under repair.
- Interfering Artificial Objects (Rule 16.1): such as sprinkler heads, paths, or benches, if they interfere with stance or swing.
- Movement Restrictions (Rule 19): such as when a ball is in a penalty area where it's impossible to make a stroke without interference from another ball or object.
- Specific Local Rules: as in the case of 'preferred lies,' where relief to one club-length is permitted.
Key Takeaways for Players:
- Club Choice: You can select any club from your bag for measurement.
- Reference Point: Measurement begins from the nearest point of complete relief (the nearest point where the interference no longer affects stance or swing).
- Direction: The ball is dropped so that it does not touch this nearest point of complete relief.
- Distance: Relief is typically one or two club-lengths from the nearest point of complete relief. Rule 19.2b allows for two club-lengths from where the ball lies if it's in a penalty area.
- Headcover: As Sam Burns' example shows, having a headcover on a club during measurement is likely not a breach, provided the total distance does not exceed what's permitted by the Rules, and no unfair advantage is gained.
Conclusion
The Rules of Golf demand precision and understanding. While some nuances might seem minor, they are crucial for maintaining the fairness of the game. In the case of a headcover on a club, the main point is not to use it to gain extra distance. If you stay within the permitted number of club-lengths, your drop is likely legal.
If you have questions about the Rules of Golf, don't hesitate to consult experts. Knowing the rules is your best ally on the course.
