Yardage Book vs Green Reading Book

Golfers use “the book” for two different jobs. A yardage book is how you play the hole from the tee to the front of the green. A green-reading book — a USGA greens guide — is how you read slope once the ball is on the putting surface. StrackaLine prints both, and it prints them together as a combo. Mixing those jobs up is why people order the wrong product, or expect a yardage page to do green-reading work it was never built to do.

Jim Stracka invented the laser-scanned green-reading map in 2007. The yardage side of the same product line comes from the same company that later put those maps into physical books — more than two million of them. If you already know you need a greens guide, start with How to Read a Green Book. If you are deciding what to put in the bag, stay here.

Yardage books, USGA greens guides, and combo books are separate products with different pages.

What a yardage book is for

A StrackaLine yardage book is built tee to green. It is the page you open on the tee, in the fairway, and for the approach — not the page you use to pick a start line on a six-foot putt.

Yardage books include complete tee-to-green measurements for every hole, along with:

• Elevation changes tee to green
• Cover distance to bunkers and penalty areas
• Distance rings
• Compass off the tee shot and to the greens

That is club and target work. Elevation tells you whether the number in the book plays longer or shorter. Cover to bunkers and penalty areas tells you what a miss actually is. Distance rings give you a repeatable way to walk off a number when you are between sprinkler heads. The compass off the tee and to the green is orientation for the hole, not a green-reading tool.

You can use a yardage book that also contains green images for approach shots and for general slope into a green, including when you are choosing a landing area. The USGA is explicit that a book which fails the scale or size limit may still be used for those non-putter jobs. The moment you use it to help read a line of play on the putting green — or for a stroke with a putter intended to finish on the green — both the scale limit and the size limit apply. That split is written out on What’s Legal? – USGA Rules.

What a USGA greens guide is for

A StrackaLine USGA greens guide is a putting-green map. It is not a second copy of the hole diagram.

USGA greens guides include:

• Dual-view topographic slope presented in percent for both views, accurate to the millimeter
• Greens scaled no larger than 3/8 inch to 5 yards (1:480)
• A 1-yard / 5-yard grid, plus surrounding hazards and sprinkler heads for orientation

The book or paper that holds those images is limited to 4 1/4 × 7 inches. No magnification of putting-green information is allowed beyond ordinary prescription glasses. The map shows slope. It does not produce a recommended line of play from the ball. How to turn those percent numbers into an aim is on How to Read a Green Book and How to Read Green Heat Maps.

Combo books bind yardage pages and USGA greens in one book that still meets the size limit.

When a combo book is the right order

Combo books exist because most competitive rounds need both jobs. You want tee-to-green numbers on the hole, and you want a legal greens guide once you are putting. One binding keeps both at USGA paper size. If you only play a course from the fairway and already know the greens, a yardage-only book can be enough. If you already have a yardage source and the course has full green data, a greens-only USGA guide is the narrower order.

Not every course in the database has full green data. 31K+ courses sit in the database. 13,000+ of those have full hyper-accurate green data. The store listing for a course tells you which options exist. That is the check to make before you assume a combo is available. How to Order a Yardage Book walks through the search.

Printed book, app, or both

A printed greens guide and a phone map are not interchangeable in a competition. Digital putting-green images still have to meet the same scale and size limits. Zooming a green past 3/8 inch to 5 yards, or using a device to produce a recommended line of play from ball location, breaches Rule 4.3. The paper-versus-phone decision is on Printed Green Book vs App. The how-to video for the printed book is on How to Read a Green Book (video).

Who orders which product

Individual golfers search a course and buy a single book or a digital option on StrackaLine.com — checkout is not on this site. Facilities and pro shops order greens guides and yardage books in quantity through wholesale book pricing and StrackaLine facilities, including custom covers. College teams use the NCAA program for season book packages and stats. More of those guides live on Resources.

FAQ

Can I read putts from a yardage book?

Only if the putting-green images in that book meet both the scale limit (3/8 inch to 5 yards or smaller) and the size limit (4 1/4 × 7 inches), and you use them the way Rule 4.3 allows. A yardage page by itself is for the hole, not for a recommended putting line.

What is the difference between the 31K+ course count and 13,000+ green data?

31K+ is courses in the database. 13,000+ is the subset with full hyper-accurate green data. Yardage can exist on a course that does not yet have a full greens guide.

Do combo books still meet USGA size?

The printed book still has to stay at or under 4 1/4 × 7 inches, and every green image used to read a line of play on the putting green still has to meet the scale limit. Combo is yardage plus USGA greens in one legal-size book, not a larger book.
