Yardage Book
A yardage book is a pocket-sized booklet that maps every hole on a specific golf course, marking distances to greens, hazards, and landing areas so a player can plan each shot.
What is a yardage book?
Golfers reach for a yardage book when they want to know exactly how far they sit from a target. Guesswork off the tee markers only goes so far. Each book is custom-made for one course, with a page for nearly every hole. Inside, a player finds the layout of the hole drawn from above, the distance from each tee box, and the location of hazards like fairway bunkers and water, according to GolfLink and The Left Rough.
The reason for all that detail is consistency. Pin positions and tee markers move from day to day, so the raw number to the flag keeps shifting. A yardage book gives a fixed reference a golfer can trust regardless of where they tee off, as GolfLogix notes. It sits somewhere between a scorecard and a full course guide, carrying more information than the card in your pocket but small enough to fit there too, per Lightspeed.
For touring professionals, the book is close to essential. Recreational players tend to reach for one mainly on an unfamiliar course or one with big elevation changes.
What’s inside a yardage book
A typical page is built around a bird’s-eye drawing of the hole. The top of the page usually covers the tee shot, with distances to carry or reach fairway bunkers, the point where the fairway runs out, and targets a player might aim for, as ESPN’s breakdown of a PGA Tour book shows. The bottom of the page zooms in on the green complex and its depth, any tiers or ridges, and the slopes around it, per The Left Rough and Caddie AI.
Most distances reference sprinkler heads, which sit in fixed positions and make dependable markers, according to Caddie AI. Many books also record green depth, so a golfer can work out how a front pin differs from one tucked at the back.
Reading the numbers and symbols
The shorthand looks cryptic at first. A sprinkler-head note written as 140 F, 152 M, 165 B means 140 yards to the front of the green, 152 to the middle, and 165 to the back, as Caddie AI explains. A small plus or minus sign marks elevation. A number with +2 beside it plays roughly two yards longer because the shot is slightly uphill, according to Women’s Golf. Arrows scattered across the page show which way the ground slopes, whether in the fairway or on the green. Most books include a legend that decodes the rest.
Yardage book vs green book
The terms get used loosely, and some products combine both, but they describe different things. A yardage book maps the whole hole and centres on distances from tee to green. A green book, sometimes called a greens guide or green-reading book, zooms in on the putting surface and shows the contours and slope percentages that help a player read how a putt will break, as StrackaLine and GolfLogix describe.
Many modern products fold the two together. PuttView and StrackaLine, for instance, sell combined books that carry full yardages on one part of the page and detailed green maps on another.
| Yardage book | Green book | |
|---|---|---|
| Main focus | Distances across the whole hole | Slope and contour of the putting green |
| Helps with | Club choice, carries, hole strategy | Reading the line and speed of putts |
| Typical detail | Tee shots, hazards, layups, green depth | Slope %, fall lines, break arrows |
Yardage books vs GPS and rangefinders
A fair question in 2026: why carry a paper book when a watch or rangefinder reads a distance in seconds? The answer starts with the rules. Professional golfers cannot use GPS devices in competition, and laser rangefinders are restricted, as GolfLink and Golfible report. The PGA of America began allowing rangefinders at its major championships in 2021, with the slope-reading feature switched off, according to GolfLink.
The two tools also do different jobs. A rangefinder or GPS reads a live distance to a point the player picks. A yardage book holds pre-measured numbers a golfer can study before the round and trust under pressure, plus strategy notes a device cannot supply, as GolfLink and Caddie AI point out. Plenty of golfers carry both.
Are yardage books allowed under the rules of golf?
Yes, with limits that apply mainly to the greens. Yardage books are legal in both professional and amateur play, as Golfible and The Left Rough confirm. What changed in 2019 was how much green-reading detail a book may hold. Under Rule 4.3a, the USGA and R&A restricted the green maps players use to read the line of a putt.
The regulation sets two limits for any image used to read a line of play on the putting green. The scale cannot be larger than 3/8 inch to 5 yards, and the book or sheet itself cannot exceed 4 1/4 by 7 inches, per the USGA. Books that meet both limits, such as approved StrackaLine and PuttView editions, stay legal for reading putts. A book that exceeds the limits can still help a player judge an approach shot, just not read a putt on the green.
Types of yardage books
Books range from simple to elaborate, and the right one depends on how a golfer plays.
Basic pro-shop books give a hole-by-hole overview, with distances to the green and the main hazards. They usually cost around 10 to 20 dollars and suit beginners or anyone playing a course once, as The Left Rough notes. Mid-level books add green detail, fairway slopes, and distances from the back of the tee boxes, and tend to run 20 to 40 dollars. The most detailed editions, often combined yardage-and-green books, can include slope percentages and break arrows on the greens, priced around 40 to 50 dollars, according to The Left Rough and PuttView.
| Type | Typical detail | Rough price |
|---|---|---|
| Basic pro-shop book | Hole overview, distances to green and hazards | $10–$20 |
| Mid-level book | Adds green info, fairway slopes, tee-box distances | $20–$40 |
| Detailed green-map book | Slope %, break arrows, full tee-to-green data | $40–$50 |

Frequently Asked Questions
Do amateur golfers use yardage books?
Yes, especially in competitive amateur events and on courses they do not know well. Recreational players reach for them less often, since the benefit shrinks at lower levels of competition.
Does every golf course have a yardage book?
No. Many courses, especially public ones, do not sell them in the pro shop. Mapping companies like StrackaLine and PuttView cover tens of thousands of courses, so a book can often be bought online instead.
What is the difference between a yardage book and a scorecard?
A scorecard records strokes and lists hole lengths and par. A yardage book maps each hole in detail, with distances to hazards and targets that a scorecard never shows.
Can a yardage book help with putting?
Some can. Combined yardage-and-green books show slope and break on the greens, within the size and scale limits the rules allow.
