How to keep score in golf: what counts as a stroke, how penalties are added, and how not to lose count

1. How golf scoring works

In the most common format, stroke play, you count every stroke it takes to get the ball from the tee into the hole. That number is your score for the hole. Add the holes together and you have your score for the round. The player with the lowest total wins.

Every hole has a par: the number of strokes a good player is expected to need, usually 3, 4 or 5. Scores are often described relative to par:

On the card you only write the number. One more rule matters from day one: in stroke play you must finish every hole. Rule 3.3c says a player must hole out at each hole, so a short putt you "would have made" still has to be played and counted.

2. What counts as a stroke (and what does not)

The Rules of Golf definitions describe a stroke as "the forward movement of the club made to strike the ball." Everything below follows from that one sentence.

The whiff is the one beginners argue about most. If you meant to hit the ball, it counts, however embarrassing it felt. If you want to count putts separately for your stats, our guide on how to count putts in golf explains the fringe convention in more detail.

3. Penalty strokes: OB, lost ball, water, unplayable and wrong ball

Penalty strokes are added to the strokes you actually made. The five situations below cover almost everything a beginner meets in a normal round.

Out of bounds: 1 stroke, play again from where you hit

Under Rule 18.2b, if your ball is out of bounds you must take stroke-and-distance relief: add one penalty stroke and play again from where you made the previous stroke. Example: your tee shot goes over the white stakes. That was stroke 1, the penalty is stroke 2, and the ball you hit from the tee again is your third stroke. This is why golfers say "hitting three off the tee."

Lost ball: 1 stroke, and you get three minutes to search

Rule 18.2a says a ball is lost if it is not found within three minutes after you or your caddie begin searching. The penalty is the same as out of bounds: one stroke, and play again from where you last hit. To save the walk back, you may play a provisional ball before you go looking (Rule 18.3). If the first ball is found in time, you continue with it and the provisional is abandoned; if not, the provisional becomes your ball in play.

Water and other penalty areas: 1 stroke

The Rules call water hazards penalty areas, marked red or yellow (Rule 17). You may play the ball as it lies without penalty, but if you take relief, Rule 17.1d gives you these options, each costing one penalty stroke:

• Stroke and distance: play again from where you hit the previous shot.
• Back-on-the-line: drop outside the penalty area, keeping the point where the ball last crossed its edge between you and the hole.
• Lateral relief (red only): drop within two club-lengths of where the ball last crossed the edge of a red penalty area, no nearer the hole.

Unplayable ball: 1 stroke (2 for one bunker option)

If your ball is under a bush or against a tree, Rule 19 lets you decide it is unplayable. You are the only one who can make that call, and it is allowed anywhere except a penalty area. Under Rule 19.2 you then have three options for one penalty stroke: stroke and distance, back-on-the-line, or lateral relief within two club-lengths. In a bunker (Rule 19.3), the back-on-the-line and lateral drops must stay in the bunker for one stroke; dropping back-on-the-line outside the bunker costs a total of two penalty strokes.

Wrong ball: 2 strokes, and the wrong-ball strokes do not count

Hitting someone else's ball is the classic beginner mistake. In stroke play Rule 6.3c gives you the general penalty of two strokes. The strokes you made with the wrong ball are not counted, and you must go back and play your own ball. If you do not correct it before you start the next hole (or, on the last hole, before you return your card), you are disqualified. Teeing off from outside the tee markers works the same way under Rule 6.1b: two strokes, and that shot does not count.

Rules quoted from the current Rules of Golf as published by The R&A, which writes them jointly with the USGA. Courses and competitions can add Local Rules, so check the scorecard or notice board where you play.

4. How to fill out a golf scorecard: a nine-hole example

Here is a front nine played by a beginner, with each column filled in the way you would count it. "Strokes" is the number of swings that counted; penalties are kept in their own column so you can see where the extra strokes came from. The number that goes on the official card is the score column.

This golfer made 43 strokes but scored 48, because 5 came from penalties. That split tells you whether to practice your swing or simply aim away from the out-of-bounds line.

Who writes what on the card

In a competition, another player acts as your marker. Under Rule 3.3b the marker confirms your score with you after each hole and writes it down; at the end you check every hole, both of you certify the card, and you return it promptly. Two outcomes matter:

• If a hole score you return is higher than what you actually made, the higher score stands.
• If it is lower, or a hole is left blank, you are disqualified.

You do not have to add up the total or work out your handicap. Rule 3.3b(4) makes that the Committee's job. Get each hole right and the rest follows.

5. Gross, net, Stableford and maximum score in plain English

Rule 3.1c separates two kinds of score:

• Gross score: all strokes made plus all penalty strokes. In the example above, 48.
• Net score: the gross score minus the handicap strokes you receive. If, say, you received 9 strokes over these nine holes, your net score would be 39.

Stableford: points instead of strokes

In Stableford (Rule 21.1) you score points on each hole against a fixed target, which is par unless the Committee sets another. The highest total wins, and a bad hole costs you at most zero points instead of ruining the round.

Scored against par with no handicap, the nine holes above earn 7 points: 1 each for the bogeys on holes 1, 2 and 7, 2 each for the pars on holes 4 and 6, and 0 for the four holes that were two or more over.

Maximum score: a cap on blow-up holes

In Maximum Score play (Rule 21.2), each hole is capped at a number set by the Committee, "such as two times par, a fixed number or net double bogey." Separately, when you post a score for a handicap, the Rules of Handicapping (Rule 3.1b) cap each hole at net double bogey: par + 2 + any handicap strokes you receive on that hole. A golfer receiving no stroke on hole 8 above (par 5) would post 7 there instead of 8. Golfers who do not yet have a Handicap Index are capped at par + 5 under Rule 3.1a.

6. Common scorekeeping mistakes beginners make

• Not counting the whiff. A swing made to hit the ball is a stroke, hit or miss.
• Counting OB as one shot instead of two. Out of bounds adds a penalty stroke and sends you back to replay; after an OB tee shot you are hitting three.
• Adding two strokes for water. A penalty area costs one stroke, not two.
• Forgetting the tap-in. In stroke play you hole out, and that last putt counts.
• Counting the strokes made with a wrong ball. They are not counted; the two-stroke penalty replaces them.
• Counting the ball that fell off the tee. If you had not swung at it, re-tee with no stroke and no penalty.
• Writing the score down on the next tee, or after nine holes. On a messy hole with a penalty and a three-putt, memory is where strokes go missing.

7. How to never lose count: count each shot on your wrist

Most of the mistakes above have the same root: the number was reconstructed after the fact. The fix is to record each stroke the moment it happens. A pencil means taking your glove off, and a plastic clicker cannot tell a putt from a penalty.

GolfCounter, our app, is a stroke counter built for exactly this. On the Apple Watch you tap once per stroke, putts have their own counter, and OB, water, lost ball and unplayable each have a penalty counter, so the scorecard above fills itself in as you play. A long press removes the last stroke if you tap by mistake. The Watch counts on its own, so the iPhone can stay in your bag; the round is sent to the phone when the two connect again.

GolfCounter does not have GPS or yardages: it keeps the score, and you keep your rangefinder. Recording rounds (scores, putts, penalties, the Apple Watch counter, history and stats) is free. AI round analysis and an ad-free app are part of Premium, a subscription with a free trial. See the GolfCounter app page for details, our guide to using the Apple Watch as a golf stroke counter, or our comparison of Apple Watch golf score apps if you also want GPS.

Summary

Keeping score in golf comes down to three habits. Count every swing at the ball, including misses and tap-ins. Add one penalty stroke for out of bounds, a lost ball, a penalty area or an unplayable lie, and two for a wrong ball. Record each hole before you leave the green, or count each shot on your wrist as you go. Gross, net and Stableford are then just different ways of adding up the same honest numbers.
