What Are the Rules of Golf?

Trying to learn the rules of golf can feel like a heavy lift, but knowing the fundamentals is the fastest way to play with more confidence and enjoy your rounds. This guide breaks down the essential rules you’ll actually encounter on the course, explained in simple terms, so you can spend less time feeling confused and more time hitting great shots.

The Core Principles: Playing with Integrity

Before we get into specific situations, it’s helpful to understand the spirit of the game. The Rules of Golf are built on a few simple, foundational ideas. If you keep these in mind, you’ll be on the right track even when you don't know the exact rule for a scenario.

Play the Course as You Find It

This is golf’s golden rule. The game is about adapting to the challenge presented by the course designer and by nature itself. This means you don’t get to improve your circumstances. If your ball rolls into an old divot in the fairway, you have to play it from there. If it settles behind a tree, you need to navigate around it. The fun and challenge of golf come from dealing with these imperfect situations. Resisting the temptation to nudge your ball to a better spot (a common beginners' mistake) is the first step toward becoming a true golfer.

Play Your Own Ball

It sounds obvious, but hitting the wrong ball happens to everyone eventually. To avoid this, always play a ball with a unique mark. Use a sharpie to draw a specific dot pattern, your initials, or a small logo. Before you hit any shot, especially if it’s near another player's ball, take a quick moment to confirm it’s yours. Hitting the wrong ball results in a two-stroke penalty in stroke play, so a few seconds of diligence can save you shots and embarrassment.

Stroke Play vs. Match Play

It's also good to know what format you're playing. Most everyday rounds are stroke play, where your goal is to have the lowest total score for the round. The score you write down on each hole matters. In match play, you compete against an opponent to win individual holes. If you shoot a 4 and they shoot a 5, you win the hole. The total score doesn't matter, only the number of holes won. Some B-roll apply differently in each format, but for today, we’ll focus mainly on the rules for stroke play, as it’s what most golfers play during a casual round.

On the Teeing Area: Starting Right

Every hole starts in the teeing area, but what exactly does that mean? Getting this right prevents you from having to restart the hole.

Defining the Teeing Area

The “teeing area” isn't just a general spot. It’s a specific rectangle defined by the two tee markers for your set of tees (e.g., white, blue, red). The front edge is the line connecting the front of the two markers, and the sides extend two club-lengths back from that line. You must have some part of your ball behind that front line when you tee off.

A common mistake is teeing the ball up in front of the markers for a slightly shorter shot. This is not allowed. Your feet can be outside the box, but the ball itself must be within that two club-length deep rectangle. You can tee a ball up a full two club-lengths behind the front edge if you wish, which can sometimes be a smart strategic play on a long par 3.

What if You Play from the Wrong Place?

So, what happens if you tee off from outside the teeing area? The penalty depends on the format.

  • In stroke play, it’s a two-stroke penalty, and you must cancel the shot you just hit and replay it from a correct spot within the teeing area. The stroke you hit from outside the box doesn't count, but you add two penalty strokes to your score for that hole before you tee off again. If you fail to correct this mistake and tee off on the next hole, you could be disqualified.
  • In match play, there's no stroke penalty, but your opponent has the choice. Theyことができるmake you cancel the stroke and play again from the correct spot, or they can let the shot stand. They’ll likely make you re-hit it if you happened to hit a great shot!

Playing the Ball: Fairways an Rau

Once your ball is in play, the principle of "play it as it lies" takes over. However, the rules do permit you to deal with certain objects and ground conditions.

Loose Impediments and Movable Obstructions

It’s important to know what you can and can't move around your ball. The rules make a distinction between natural objects and artificial objects.

  • Loose Impediments: These are natural, unattached things like leaves, twigs, stones, and animal droppings. You are generally allowed to move loose impediments without penalty anywhere on the course, except when your ball also moves in the process (in which case you get a one-stroke penalty, and must replace your ball).
  • Movable Obstructions: These are artificial, man-made objects you can move with reasonable effort, like garbage cans, rakes, water bottles, and tee markers that are not in use. You can move these objects at any time, without penalty, even if your ball moves. You just have to put your ball back where it was.

The one big exception: in a bunker or penalty area, you cannot move a loose impediment. So, if a leaf is behind your ball in the bunker, you have to play the shot with it there.

Free Relief from Abnormal Course Conditions

Sometimes your ball lands in a place that isn't considered a fair part of the challenge. These are called "abnormal course conditions," and you usually get free relief. This includes:

  • Immovable Obstructions: Artificial objects you can't easily move, like a cart path, sprinkler head, or fence.
  • Casual Water: Any temporary accumulation of water (like a puddle from rain storms or a leaky sprinkler).
  • Ground Under Repair: An area marked with a white line, indicating it's being worked on by the grounds crew.

When you take free relief, you must find your Nearest Point of Complete Relief. This is the spot, no closer to the hole, where you can stand and swing without any interference from the condition. From that spot, you get to drop your ball within one club-length. This is one of the most common rulings, and knowing how to do it correctly speeds up play and saves you frustration.

Dealing with Trouble: Penalties for Bad Luck (or Bad Shots)

Everyone finds trouble on the golf course. The key is knowing what your options are and making a smart decision that limits the damage.

Penalty Areas (Yellow and Red Stakes)

Water hazards and other tough areas are now simply called "penalty areas," marked with either yellow or red stakes or lines.

If your ball is in a yellow penalty area, you have two options:

  1. Play it as it lies (if you can) without grounding your club.
  2. For a one-stroke penalty, you can take "stroke-and-distance" relief by going back to where you last played your shot from and hitting again.
  3. Also for a one-stroke penalty, you can take "back-on-the-line" relief. Imagine a line going from the hole through the point where your ball last crossed into the penalty area. You can drop your ball anywhere on that line as far back as you want.

If your ball is in a red penalty area, you have the same options as a yellow area, plus one extra option for a one-stroke penalty:

  • Take lateral relief. Find the spot where the ball last crossed into the penalty area. You can drop a ball within two club-lengths of that spot, no closer to the hole. This is often the easiest and most-used option.

Your Ball is Lost or Out of Bounds

Out of Bounds (O.B.) is usually marked with white stakes or fences. If your ball is lost (you can't find it within three minutes) or goes O.B., the standard penalty is stroke and distance. This means you add one penalty stroke and go back to the spot you just played from to hit another shot. Hitting a provisional ball from the tee is always a good idea if you think your first shot might be lost or O.B.

For casual rounds, many courses have adopted a local rule that offers a speedier alternative. Instead of going back, you can find where your ball was lost or went out of bounds. You can then go to the nearest fairway edge, no closer to the hole, and drop your ball from there with a two-stroke penalty. While costly, it saves a lot of time and is a great option for friendly games.

Unplayable Ball in a Bunker

In a bunker, you cannot touch the sand with your club before making your downswing. This "grounding of the club" is a penalty. If your ball is in a terrible spot, like right up against the lip, you can declare it unplayable. For one penalty stroke, you can drop the ball somewhere else inside the bunker. For a two-stroke penalty, you can take the ball completely out of the bunker, dropping on a line behind the bunker from the hole.

On the Green: Finishing the Hole

Things get a little simpler on the putting green, which is defined as anywhere on the hole you're playing that is specially prepared for putting.

Marking, Lifting, and Cleaning is A-OK

Once your ball is on the green, you can mark its spot (with a coin or ball marker), lift it, and clean it. This is highly recommended to ensure you have a clean surface for your putt. Just be sure to always put the mark down first before you touch the ball.

Repair Almost Anything

The rules now allow you to repair almost any damage on the green. This includes old ball marks, spike marks, and damage from animals. The better the surface, the better everyone’s chances of holing a putt. It’s good etiquette to fix your own ball mark plus one other you see while you're there.

Hitting the Flagstick

In a major simplification, there is no longer a penalty if your ball hits the flagstick when you putt from the green. You can choose to leave the flagstick in or have someone tend to it and remove it - whatever makes you most comfortable. This has dramatically helped speed up play!
