The Complete Golf Stats Glossary
Every golf stat, defined in plain English and ranked by how much it actually tells you. Bookmark this page and use it to decode any number on your scorecard or in your app.
Golf has more numbers attached to it than almost any other amateur sport, and most of them arrive with no explanation. You finish a round, open an app, and see a wall of acronyms — GIR, SG, SCR%, SS% — with no sense of which ones matter and which are noise. This golf stats glossary fixes that.
Below is every stat worth knowing, defined in plain language, grouped by what it measures, and ranked by how much it actually reveals about your game. Where a term deserves its own deep dive, there’s a link to a full explainer. Bookmark this page and come back to it whenever a number on your scorecard or in golfity leaves you guessing.
How to Read This Glossary
Not every stat carries the same weight. A useful way to think about it:
- Outcome stats tell you what happened: your score, your putts, your greens hit. Easy to record, but they blend good and bad play together.
- Strokes gained stats tell you why it happened by comparing every shot to a benchmark. Harder to compute by hand, far more diagnostic.
Traditional stats aren’t useless — they’re just incomplete. The best approach is to read them alongside strokes gained, which is exactly how golfity’s dashboard lays them out.
Scoring and Handicap Terms
Gross score — Your raw total: every stroke you took, penalties included, before any handicap adjustment. Shoot an 88, your gross score is 88.
Net score — Your gross score minus your course handicap. A 15-handicap who shoots 88 nets a 73. The gross vs net comparison walks through the arithmetic with examples.
Handicap index — A portable number (like 12.4) representing your demonstrated ability, calculated from the best 8 of your last 20 score differentials under the World Handicap System. Learn how the handicap calculation works step by step.
Course handicap vs playing handicap — Your handicap index converts into a course handicap for the specific tees you play, then a playing handicap after any format allowances. The distinction between index, course, and playing handicap trips up a lot of golfers.
Course rating — The score a scratch golfer is expected to shoot on a given course and tee, expressed to one decimal (e.g., 72.4).
Slope rating — How much harder a course plays for a bogey golfer than a scratch golfer, on a scale of 55 to 155 with 113 as the baseline. Both are unpacked in course rating and slope rating explained.
Stableford — A scoring format that awards points per hole instead of counting strokes, which caps the damage of a blow-up hole. See Stableford scoring with examples, or work out a card with the Stableford calculator.
Traditional Ball-Striking and Short-Game Stats
Green in regulation (GIR) — You hit a green in regulation when your ball is on the putting surface with at least two putts left for par (green on the tee shot for a par 3, second shot for a par 4, third for a par 5). It’s the single best traditional predictor of scoring. Full definition in what is a green in regulation.
Fairways hit (FIR) — The percentage of par-4 and par-5 tee shots that finish in the fairway. Useful, but it treats a 6-inch miss into light rough the same as a shot out of bounds, which is why fairways hit can mislead you.
Driving distance — Average carry-plus-roll off the tee. It matters more than most amateurs admit and less than most amateurs hope, a tension covered in driving distance vs accuracy.
Scrambling — The percentage of holes where you miss the green but still make par or better. A short-game survival stat. See what is scrambling in golf.
Sand save percentage — Scrambling restricted to greenside bunkers: how often you get up and down from the sand. Defined in what is sand save percentage.
Putts per round / putting average — Total putts across 18 holes. It’s the most quoted putting stat and one of the most misleading, because hitting more greens leaves you longer first putts. That paradox is why 30 putts can be great or terrible and why a “good” putting average depends on context.
Putts per GIR — Putts taken only on greens you hit in regulation. It strips out the chip-close-and-tap-in holes that flatter your raw putting average.
Strokes Gained Terms
Strokes gained is the framework professional golf switched to for a reason: it measures every shot against a benchmark of expected strokes from that exact spot, so it isolates where you actually gain and lose ground.
Strokes gained (SG) — For any shot, the expected strokes to hole out from where you started, minus the expected strokes from where you ended, minus one for the stroke you took. Positive means you gained ground on the benchmark; negative means you lost it. Start with what is strokes gained.
Mark Broadie — The Columbia Business School professor whose research built the strokes gained model now used on the PGA Tour. Background in Mark Broadie, the creator of strokes gained.
SG: Off the Tee (SG-OTT) — Strokes gained on tee shots on par 4s and par 5s. Covered in what is strokes gained off the tee.
SG: Approach (SG-APP) — Strokes gained on approach shots into the green. For most amateurs this is the biggest single lever on their scores. See what is strokes gained approach and why it matters more than GIR.
SG: Around the Green (SG-ARG) — Strokes gained on shots within roughly 30 yards of the green that aren’t putts. Explained in understanding strokes gained around the green.
SG: Putting (SG-P) — Strokes gained once the ball is on the green, based on make percentages from every distance. Deep dive in understanding strokes gained putting.
SG: Tee to Green (SG-T2G) — Off the tee plus approach plus around the green — everything except putting. See what is strokes gained tee to green.
Benchmark — The reference group your shots are measured against (a scratch golfer, the PGA Tour average, a 10-handicap, etc.). Choosing the right one changes what your numbers mean, which is why golfity shows different benchmarks and why comparing to a 10-handicap can beat comparing to a pro.
Diagnostic and Scoring-Pattern Terms
Proximity to the hole — Your average distance from the pin after an approach shot, usually broken out by yardage band. Getting closer, on average, is what drives the approach game, more than hitting your favorite number, as shown in why getting closer beats your favorite yardage.
Three-putt — Taking three putts on a single green. Rare among low handicaps, common above 15, and more expensive than it feels — see the real cost of a three-putt.
Blow-up hole — A hole played several strokes over par (double bogey or worse) that wrecks an otherwise solid round. The scoring damage is quantified in what blow-up holes cost you.
Expected strokes — The average number of strokes a benchmark golfer needs to hole out from a given distance and lie. It’s the foundation every strokes gained figure is built on.
Turning the Glossary Into Lower Scores
Knowing the definitions is step one. The payoff comes from reading these numbers together and acting on the gaps. A round where you hit 11 greens but shot 82 points to putting or short game; a round where you scrambled well but still shot high points to ball-striking. Strokes gained connects those dots automatically.
You don’t need launch monitors or GPS pucks to get there. golfity calculates strokes gained from a simple round entry, turns it into the categories above, and stacks it against the benchmark you choose. Try the strokes gained calculator to see it work on a single shot, or read what your golf stats are telling you to start acting on the full picture.
