I didn’t think twice about ball markers until I nearly caused a rules kerfuffle in my club’s four-ball. On the 11th green my coin—an old dime—slid downhill after I set it, creeping just enough to fluster my playing partner who swore I’d moved his putting line. Awkward silence, frantic Rule-book search, and a tapped-in three-putt later, I promised myself: time to learn proper marker etiquette. If you’ve ever fumbled for loose change or wondered whether that souvenir poker chip is legal in competition, this guide unpacks everything about golf ball markers—their uses, rules, types, and smart buying tips.
What Exactly Is a Ball Marker?
A ball marker is any small, flat object placed directly behind a golf ball on the green to mark its position while you lift, clean, or realign the ball. The Rules of Golf call it a “ball-marker,” hyphen and all (Rule 14.1). Acceptable markers include:
- Manufactured discs or chips
- Circular tokens (poker chips, casino chips)
- Small coins
- T-markers built into pitch-mark repair tools (when detached)
The USGA and R&A emphasize flatness—markers mustn’t jut above the putting surface enough to influence a rolling ball.
The Rules You Need to Know
| Rule | Situation | Penalty if Breached* |
|---|---|---|
| 14.1a | Ball must be marked before lifting on the putting green. | One stroke |
| 14.1b | Marker must be immediately behind or right next to ball. | One stroke |
| 15.3c | Player can require another to mark or move marker interfering with line. | No penalty unless refused |
| 9.4b | Moving your own marker accidentally. | No penalty—replace |
| 9.5b | Moving someone else’s marker. | One stroke & replace |
*General penalty for stroke play unless otherwise noted.
Proper Marker Etiquette
- Align quietly. Kneel or crouch low to avoid casting shadows over another player’s sight line.
- Request rather than reach. Never move another player’s marker without invitation.
- Mark, clean, replace. Lift the ball with fingertips—not the putter blade—to avoid scuffing greens.
- Use small, unobtrusive markers in match play. Large poker chips are fun in casual rounds but can annoy opponents on tight lag-putt lines.

Pros & Cons of Different Marker Styles
- Pros
- Metal discs resist wind gusts better than plastic.
- Magnetic hat-clip markers stay handy—no pocket digging.
- Large poker chips double as alignment aids during practice.
- Cons
- Poker chips can obstruct other players’ putting lines.
- Coins may tarnish and stain glove pockets.
- DIY bottle caps sometimes catch mower blades—greenkeepers frown.
Buying Tips: What to Look For
- Flatness & Diameter – Keep thickness under 2 mm; diameter under 1¼ inch (32 mm) avoids blocking sight lines.
- Contrast Color – Bright edges (red, neon) help you spot marker quickly; dark colors vanish on shaded greens.
- Edge Grip – Knurled or grooved rims ease pickup without bending fingernails.
- Magnetic Compatibility – Steel inserts stick to many putter heads for quick retrieval.

Frequently Asked Questions
Are large poker chips legal?
Yes, provided they are reasonably flat. In elite tournaments officials may request smaller markers to keep greens clear.
Can I use a tee as a marker?
Rule 14.1 permits “any other equipment”, but committees often prohibit tees because they protrude and can deflect putts.
What if my marker moves after I place it?
No penalty—simply replace it. Wind or accidental kick? Same action, no stroke.
May I align my ball using the marker’s edge?
Yes; you can spin the ball for alignment after lifting, as long as the ball returns to precisely that spot.
Should I mark off the green?
Only required on putting surface, but courteous in fringe if you’re cleaning mud or practicing read.
Conclusion
Ball markers might be the smallest pieces of gear in your bag, yet they carry outsized weight in rules, etiquette, and personal style. Keep one slim, flat marker for competition and a flashier chip for weekend games; learn Rule 14.1 so you never stumble into penalty strokes; and choose materials that fit your pocket and personality. Next time you stoop to mark that winning four-footer, you’ll do so with confidence—and maybe a touch of flair. Let us know your favorite marker style or any rule questions in the comments below!
