What Does Out of Bounds Mean in Golf?

By Spencer Lanoue
July 24, 2025

Hitting a towering drive only to watch it drift agonizingly past a line of white stakes can be one of the most disheartening moments in a round of golf. Simply put, out of bounds (often abbreviated as O.B.) is any area of the course from which play is prohibited. Think of it as the no-go zone. This article will clearly explain how to identify out-of-bounds areas, what the strict penalty is, and exactly what your options are when your shot goes astray, so you can handle the situation with confidence and keep your round moving.

Identifying Out of Bounds on the Course

First things first, how do you even know where the out-of-bounds line is? Every course defines its own boundaries, and it's your responsibility to be aware of them. The good news is that the markings are standardized and easy to spot once you know what to look for. You're primarily looking for two things: white stakes or white lines.

White Stakes

The most common way to mark out of bounds is with a series of white stakes. When you see these, you must understand a very specific point: the out-of-bounds line is determined by the nearest inside points of the stakes at ground level. This means that an imaginary line connects the inside edge of one stake to the inside edge of the next one.

  • The Stakes Themselves are Out of Bounds: This is a frequent point of confusion. According to the Rules of Golf, the stakes themselves are considered to be in the out-of-bounds area. Therefore, if your ball is touching a white stake, it is out of bounds.
  • The Line Between the Stakes: Your ball must be entirely outside that imaginary line to be O.B. If any part of your ball is inside the line and in the playable area of the course, it is considered in bounds. You could have 99% of your ball sitting in the out-of-bounds area, but as long as that 1% is touching the in-bounds side of the line, you are safe!

Imagine your ball is just beyond a white stake. The question isn't whether it's past the stake itself, but whether it's past the invisible line running between the inside base of that stake and the next one. This small detail can be the difference between playing on and taking a penalty.

White Lines

Sometimes, a course will use white paint on the ground to indicate the out-of-bounds edge, often along a fence, a road, or the edge of a practice area. In this case, the rule is even clearer.

  • The Line Itself is Out of Bounds: Just like with the stakes, the white line is located in the out-of-bounds area.
  • TheEntirety of the Ball Must Cross the Line: For your ball to be ruled O.B., it must be lying completely and totally on the other side of the white line. If any piece of your ball, no matter how small, is touching哪怕 part ofthe line, your ball is in play.

Unlike a football or tennis ball which is ruled "in" if it touches the line, a golf ball is the opposite. The line itself is out. This is a critical distinction!

The Punishment: Understanding the "Stroke a/nd Distance" Penalty

Sending a ball O.B. isn't just a frustrating mistake, it comes with one of the most severe penalties in golf. It is known as a stroke-and-distance penalty. Let’s break that down, because it’s a two-part punishment that confuses a lot of players.

  • Stroke:You must add one penalty stroke to your score.
  • Distance: You lose all the distance your shot traveled and must play your next shot from the same spot as your previous one.

A Step-by-Step Example

Let's walk through the most common scenario: your tee shot goes out of bounds.

  1. Your first swing off the tee sails past the white stakes. That counts as your first stroke (1).
  2. You are assessed awe-stroke penalty for hitting it O.B. Your score for the hole is now unofficially at two (1 + 1 penalty = 2).
  3. Because of the "distance" part of the penalty, you can’t drop where the ball went out. You must return to the tee box and hit again. This next shot will be your third stroke (3).

This is whya golfer will say, "I'm playing 3from the tee." Hitting a ball a bnd out of bounds essentially turns one bad shotswoginto three strokes before your next one even lands safely in play. This is why knowing where theO.B. markers are before you hit iyso important for good course managementanand avoiding blowout holese

What to Do When Your Ball *Might* Be Out of Bounds

You hit a slice that drifts towards the property line, but you aren't sure if it stayed in. The absolute worst thing you can do is walk all the way down there, discover it's out, and then have to make the long "walk of shame" all the way back to the tee to hit again. This slows down the group behind you and kills your own momentum.

To avoid this, you should play a provisional ball.

A provisional ball is like a backup shot. If your first ball is in bounds, you just pick up the provisional and carry on. If your first ball is lost or out of bounds, your provisional immediately becomes the ball in play, and you've already reloaded, saving a tremendous amount of time.

How to Properly Play a Provisional Ball

  1. Announce Your Intention: Before you do anything else, you must announce to your playing partners that you are hitting a provisional ball. Say something clear like, “I’m not sure about that one, I'm going to hit a provisional.” Failure to announce this means the second ball you hit automatically becomes the ball in play, and your original ball (even if found in-bounds) is considered lost.
  2. Identify the Provisional: Use a ball with a different number or a distinctive Sharpie mark so you can easily tell it apart from your original ball.
  3. Play the Shot: Hit your provisional shot from the exact same spot you just hit your original one from.
  4. The Search: Now, you and your group can head toward the area where your first ball went. You have three minutes to search for your original ball once you reach the area.
    • You Find the Original Ball In-Bounds: Great! Your provisional ball is now meaningless. Pick it up and play your original ball from where it lies. You receive no penalty strokes.
    • You Can't Find the Original, or It's O.B.: Your provisional ball immediately becomes the ball in play. You've already taken your stroke-and-distance penalty by re-hitting from the original spot. Your shot count is correct (you're lying 3, preparing to hit your 4th shot if it was an O.B. tee shot).

Playing a provisional ball is not just smart, it's good etiquette. It shows respect for your fellow golfers and helps keep the pace of play moving smoothly for everyone.

What About the Recreational 'Drop' Rule? (Model Local Rule E-5)

You may have played with someone who hit a ball a out of bounds and then simply dropped one near theeedge of the fairway, took a penalty, sand played on. This iis not part ofthe official. Ruleslof Golf - it is anaoptional.Model Local Roule (E-5) that coursescan implemento speed up paceof playa. It is especially common in casual orl club play

Here’s how it works:
