Fringe

The fringe is the narrow ring of grass that borders a putting green, cut shorter than the fairway but a touch longer than the putting surface itself. It sits between the green and whatever turf surrounds it, whether that’s fairway, rough, or a bunker.

What is the fringe?

In golf, the fringe is the closely mown band of grass that hugs the edge of a green. The grass is short enough that a ball will roll on it cleanly, but long enough that a putt rolls noticeably slower than it would on the green. Most courses cut their fringe somewhere between the height of the green and the height of the fairway.

The point of the fringe is partly practical and partly aesthetic. It gives the green a defined edge and frames the putting surface visually, and it provides a softer landing zone for approach shots that just trickle past the green. It also gives golfers a real choice on their next shot. They can putt, chip, or play a bump-and-run, depending on the lie and the distance to the hole.

A green does not need a fringe to function. Some courses use only a thin band of it, and in rare cases, the fairway runs right up to the putting surface. But on the great majority of well-maintained courses, every green has a visible band of fringe around it.

Despite how close it sits to the green, the fringe is not part of the green. Under the Rules of Golf, that distinction matters, and it changes what a player is and isn’t allowed to do.

Fringe vs. apron vs. collar

Three terms get used almost interchangeably for the grass around a green, and the overlap can confuse newer golfers. Strictly speaking, each one points to a slightly different thing:

Term	What it refers to
Fringe	The closely mown band of grass that surrounds the entire green. The most common modern term.
Collar	The ring of slightly higher grass around the green, often used as a synonym for fringe.
Apron	The closely mown area in front of the green, where the fairway transitions into the putting surface.
Frog hair	Slang for any of the above, more common in American English.

In casual play and on TV broadcasts, “fringe” tends to be the catch-all word, and most golfers use it for any grass that rings the green at the closely mown height. The R&A and USGA rulebooks do not formally define “fringe,” “apron,” or “collar” as separate areas. Under Rule 2.2a, all of that grass falls into the same category: the general area of the course.

The slang term “frog hair” goes back to at least the 1940s in American golf and was popularised in part by Sam Snead, who used it in his 1962 book “The Education of a Golfer.” The phrase plays on the Southern saying “fine as frog hair,” which uses the imaginary fineness of frog hair as a way of describing something thin or sparse.

How the fringe is maintained

Mowing height is what separates the fringe from the green on one side and the fairway on the other. The exact numbers vary by course, climate, and grass species, but the gradient is fairly consistent across the industry.

According to the USGA, putting greens at most clubs are mowed between 0.110 and 0.140 inches, while tournament-prepared greens can drop below 0.100 inches. Fairways typically sit around 0.4 to 0.5 inches, and rough is usually maintained between 1.5 and 2.5 inches. The fringe falls between the green and the fairway, often around 0.4 inches at private clubs, though some courses cut it closer to fairway height and some keep it a little higher.

Visually, the fringe usually looks slightly darker and thicker than the green next to it, with a different mowing pattern. A golfer can almost always tell where the green ends and the fringe begins just by looking at the surface.

Playing from the fringe

When a ball comes to rest on the fringe, the player has more options than they would from the rough. The grass is short enough to putt through, but loose enough that other shots are still in play.

The three most common choices are a putt, a chip with a wedge or short iron, and a bump-and-run with a hybrid or low iron. Which one a golfer picks usually depends on the lie, the distance to the hole, and how much green there is to work with between the ball and the cup. Tight, clean lies favour a putter. If the ball is sitting down or the fringe is shaggy, most golfers will reach for a wedge or short iron to get cleaner contact. A hybrid or low iron is a common choice for longer approach lines across slow fringe grass, where the goal is to get the ball rolling early and let it run.

A fringe lie is generally one of the more forgiving spots a golfer can find around the green. The ball is sitting on a clean, mown surface, and a clean strike is much easier to make than from rough or a bunker.

Fringe rules: what’s allowed and what isn’t

Because the fringe is part of the general area and not the putting green, the special permissions that apply on the green do not extend to it. This catches a lot of recreational golfers off guard.

A few things change once the ball is on the fringe rather than on the green:

A player cannot mark, lift, and clean their ball on the fringe at will. Ball-marking on the fringe is only permitted when another player asks for it under Rule 15.3, because the ball might interfere with their shot.
Pitch marks on the fringe cannot be repaired before a stroke, even if the mark is directly on the line of play. Rule 8.1 prohibits eliminating that kind of irregularity. Pitch marks on the green itself can be repaired freely.
Spike marks and other minor surface damage on the fringe likewise cannot be tapped down.
The flagstick rule still applies. A player can leave the flagstick in or have it removed for any shot from the fringe, just as they would on the green.

Stat trackers also treat the fringe differently. Most professional tours, and most amateur tracking apps that follow tour conventions, do not count a stroke played from the fringe as a putt, even when the player uses a putter. A putt is recorded only when the ball is on the green at the start of the stroke. So a clean two-shot finish from the fringe (a putter from the fringe, then a tap-in on the green) shows up as one putt in the scorecard data, not two.

Frequently Asked Questions

Why is the fringe called frog hair?

The slang comes from the old Southern American phrase “fine as frog hair,” meaning something so thin it is barely there. Frogs do not have hair, so the comparison is to something that hardly exists at all. Sam Snead used the term in print as early as 1962, and it had been in spoken use for decades before that.

Can you putt from the fringe?

Yes. Putting from the fringe is common and often the safest option when the lie is clean, and the path to the hole is mostly green. The ball will roll a little slower through the fringe before reaching the putting surface, so most golfers strike the putt slightly firmer than they would from the same distance on the green.

Is the fringe part of the green?

No, it isn’t. Under Rule 2.2a, the fringe is part of the general area of the course, while the putting green only includes the surface specially prepared for putting. A ball is on the green only if any part of it is touching the putting surface itself.

Can you mark your ball on the fringe?

Only when another player asks for it under Rule 15.3, usually because the ball might interfere with their shot. A golfer cannot mark, lift, and clean their own ball on the fringe simply for convenience, the way they can on the green.

Does a stroke played from the fringe count as a putt?

No, according to the stat-tracking conventions used by professional tours. A putt is a stroke made from the putting green. A stroke played from the fringe is recorded as a regular stroke, even if it was hit with a putter.
