Golf Round Scorecard & Stat Tracker
A digital scorecard tracking score, putts, fairways and greens in regulation, with round history saved in your browser.
Saved rounds
Rounds save in this browser. Fairways are counted on par 4s and 5s only (par 3s don't count, which is why the denominator is usually 14). A green in regulation means reaching the putting surface in par-minus-two strokes. Post your differentials to the Handicap Calculator to track your index.
Putts on greens you hit: an estimate we didn't need, and got wrong
Total putts is the sum of two things — the putts on greens you hit in regulation and the putts
on greens you missed — so reporting the first means subtracting the second. This page used to
do that by assuming a figure: (totalPutts − missedGreens × 0.6) ÷ greensHit.
0.6 putts on every green missed can't be right, and the reason isn't statistical. On a green you've missed you have to hole out with a putt unless you chip in, so putts per missed green is at least 1 in every case but a chip-in. A figure of 0.6 asserts a 40% chip-in rate. Tour players manage somewhere around two to four per cent.
| An ordinary round: 32 putts, 18 holes, 9 greens hit | |
|---|---|
| Subtracted for the 9 missed greens | 9 × 0.6 = 5.4 putts |
| Left for the 9 greens hit | 32 − 5.4 = 26.6 putts |
| Reported | 26.6 ÷ 9 = 2.96 putts per green hit |
Nearly three putts on every green you hit, from a perfectly respectable round. Simulating 2,964 rounds hole by hole with plausible putting, the estimate came out 3.20 putts per hole too high on average, and exceeded 3.00 — a figure almost nobody produces — in 59.9% of them.
The fix isn't a better constant. It's no constant: the scorecard already records putts and the green-in-regulation flag on every individual hole, so the exact figure is a plain average over the holes that qualify. No assumption, no error, and it can't drift. The estimate was solving a problem the data had already solved — which is the actual lesson: before reaching for a coefficient, check whether the thing you're estimating is sitting in the record you already keep.
The default card is a par 71, not 72
Not a bug, but worth saying, because most players assume 72. The card you start with is 36 out and 35 back: 4 par threes, 11 par fours and 3 par fives.
The front nine has the textbook shape — 2 par threes and 2 par fives around five par fours. The back keeps both par threes and drops one of the par fives, and that single hole is the entire difference between the nines. Par-71 courses are common; the number to check before you read anything into a score is the one printed on the card you actually played.

Frequently asked questions
Which statistics are worth tracking?
Fairways, greens in regulation and putts are the traditional three and are easy to record. Adding penalty shots and up-and-down conversion tells you considerably more, because those are where amateur scores are actually lost.
What counts as a green in regulation?
Reaching the green in par minus two strokes — one shot on a par 3, two on a par 4, three on a par 5. It is the statistic that correlates most strongly with scoring for amateurs, more so than driving distance or putting.
Are putts per round misleading?
Yes, on its own. A player who misses every green and chips close will have a low putt count while scoring badly, and a player hitting many greens will putt more from longer range. Putts per green in regulation is a far more honest measure.
How many rounds before the numbers mean anything?
At least ten, and preferably more. Golf is noisy enough that a single round can be several strokes from your normal standard for no discoverable reason, and drawing conclusions from one card is how people change something that was working.
Where is my data stored?
In your browser on this device, so nothing is uploaded and no account is needed. That also means it does not sync between devices and will be lost if you clear browsing data — worth exporting if a season's record matters to you.
Should I count every shot?
For handicap purposes and for honest statistics, yes. Casual mulligans and gimmes are entirely fine socially, but a card that quietly omits them produces numbers that flatter and a handicap that misrepresents — which mostly harms you in competition.
