Inward Nine
The inward nine is the traditional name for the back nine of a golf course: holes 10 through 18 on a standard 18-hole layout.
What is an inward nine in golf?
The inward nine is the last nine holes of an 18-hole golf course, holes 10 through 18. Most golfers now simply call it the back nine. The inward nine is just the older, more traditional name for that same half, which Merriam-Webster defines as “holes 10 through 18.” On a scorecard, it appears under the column marked “In,” and that label is where the name comes from.
The term only applies to a standard 18-hole course. A 9-hole course has no inward nine, and neither does a par-3 or executive course with fewer than 18 holes. It also has a natural partner: the outward nine, which covers holes 1 through 9. Together the outward nine and the inward nine make up a full round of regulation golf.
You are most likely to hear “inward nine” from older golfers, on links courses, or in British commentary, where the phrase has stuck around long after “back nine” became the everyday term elsewhere.
Inward nine vs. back nine
They are the same thing. The inward nine and the back nine both mean holes 10 through 18 of an 18-hole course, and golfers use the two names interchangeably. The difference is only one of style and era.
“Back nine” is the plain, everyday term, especially common in the United States. “Inward nine” is the traditional term, rooted in how the oldest courses were laid out, and it carries a slightly more formal or historical feel. When a commentator says a player “came home in 33,” that closing 33 is the score on the inward nine. The break between the two halves, taken between the ninth and tenth holes, is known as the turn.
Inward nine and outward nine
The inward nine has a matching first half, the outward nine. Where the inward nine is the back nine, the outward nine is the front nine, holes 1 through 9. Both are the older names for the two halves of the course, and both show up on the scorecard as “Out” and “In.” The table below lines up all four terms so the pairing is clear.
| Term | Holes | Modern name | Scorecard label | Direction |
|---|---|---|---|---|
| Outward nine | 1 through 9 | Front nine | OUT | Plays away from the clubhouse |
| Inward nine | 10 through 18 | Back nine | IN | Loops back toward the clubhouse |
A quick way to remember it: the outward nine heads out, the inward nine comes back in. That single idea explains both names and the scorecard columns at once.
Where the term comes from
The names trace back to the early links courses of Scotland, where golf grew up on the sandy coastal ground between the towns and the sea. These courses were laid out in a long strip. Players went out from the clubhouse in a line of holes to the far point of the course, turned, and played back in along a parallel line. Nine holes out, nine holes back in, and the two halves became the outward nine and the inward nine.
The Old Course at St Andrews is the classic example of this out-and-back shape. It also set the template for the modern round. In 1764, the Society of St Andrews Golfers combined the first four short holes into two, reducing the course from 22 holes to 18, and that number became the worldwide standard, according to the PGA Tour and Scottish Golf History. On a routing like this, “front” and “back” never quite fit. As Golf Digest has pointed out, the outward and inward nines are the more accurate description of what a golfer actually plays at St Andrews.
Most courses built since then use two separate loops, with the first and tenth tees near the clubhouse for convenience. The strict out-and-in geometry is rare in new construction, but the language stuck. Scorecards still label the two nines “Out” and “In,” and golfers still talk about “going out” on the front and “coming in” on the back.

Frequently Asked Questions
Is the inward nine the same as the back nine?
Yes. Both refer to holes 10 through 18 of an 18-hole golf course. “Inward nine” is the older, traditional name; “back nine” is the more common everyday term today.
What is the outward nine?
The outward nine is the front nine, holes 1 through 9. It is the first half of the course and appears on the scorecard under the “Out” column.
Why does a scorecard say “In” instead of “back”?
Early Scottish links courses ran out from the clubhouse and then back in. The returning half was the inward nine, shortened to “In” on the scorecard, and the label stuck even after course design changed.
Does the inward nine always mean holes 10 to 18?
On the course itself, yes. In a personal round that starts on a different hole, such as a shotgun-start tournament, a golfer might play holes 10 to 18 first, in which case those become that round’s front nine even though they remain the course’s inward nine.
Do golfers still say “inward nine”?
It is less common than “back nine” in everyday American golf, but it is still heard, particularly in Britain, on traditional links courses, and in television commentary.
