Every golf course is covered in colored stakes, sprinkler heads, and painted numbers — and most beginners have no idea what any of them mean. This guide explains every yardage marker you'll encounter on the course, what each color means, and exactly how to use them to pick the right club.
| Marker type | Color | Distance | What to know |
|---|---|---|---|
| Stake / post in fairway | White | 150 yards | The most common system. A white stake or post on the left or right side of the fairway marks exactly 150 yards to the center of the green. This is the universal reference point every golfer starts with. |
| Stake / post in fairway | Red | 100 yards | A red stake marks 100 yards to the center. At 100 yards you're typically in wedge territory. Some courses use a different color — check the scorecard or ask the starter. |
| Stake / post in fairway | Blue | 200 yards | A blue stake marks 200 yards to the center. This helps you gauge which club to pull when you're still far out on a long par-4 or par-5. |
| Sprinkler head | Usually white/grey | Varies — number is stamped on top | Sprinkler heads are often stamped with the yardage to the center or front of the green. More accurate than stakes because they are exactly where you find them (no "is this stake in the rough or fairway?" confusion). |
| Colored dot / circle in fairway | Red, white, or blue | 100, 150, or 200 yards respectively | Some courses use painted circles or discs flush with the turf instead of stakes. Same color-coding as stakes: red=100, white=150, blue=200. Easier to walk past than a post. |
| Cart path marker | Painted number | Exact yardage painted on path | Many courses paint the yardage directly on the cart path at regular intervals. Often measured to the front of the green rather than the center — check the scorecard. |
These stakes have nothing to do with distance — they define hazard boundaries and penalty areas. Crossing one of these lines with your ball triggers a penalty stroke.
| Color | What it marks | Rule | What happens if your ball goes there |
|---|---|---|---|
| White | Out of bounds (OB) | Rule 18.2 | Do NOT play the ball from beyond white stakes. You must take stroke-and-distance relief: return to where you played from and add 1 penalty stroke. |
| Yellow | Penalty area (water hazard) | Rule 17 | Your options: play it as it lies, take stroke-and-distance back to where you played from, or drop behind the hazard on the line where the ball crossed (back-on-line). Each option costs 1 penalty stroke. |
| Red | Lateral penalty area | Rule 17 | Same options as yellow stakes, plus you may drop within 2 club-lengths of where the ball crossed the margin (lateral relief). Still 1 penalty stroke. |
Look for a white stake or post on the left or right side of the fairway. This marks exactly 150 yards to the center of the green on almost every hole at almost every course. It's the universal starting point. From here you can walk toward or away from the green to fine-tune your yardage.
Walk to the nearest sprinkler head and look for a number stamped or engraved on top. This is often the most precise yardage you'll find on the course. Sprinkler heads are measured to the center or front of the green — check the scorecard or the yardage book to confirm which your course uses.
The yardage markers always measure to the center of the green. If the flag is in the back, add 5–15 yards. If it's up front, subtract 5–15 yards. Many scorecards include a daily pin sheet (A/B/C zones or front/middle/back). When in doubt, the middle is usually safe — going past the hole is better than being short of the green on most approaches.
Yardage is measured flat — elevation change affects how far the ball actually flies. A steep uphill shot plays longer than the marker says (add 5–15% of yardage). A steep downhill plays shorter (subtract 5–15%). As a beginner, a rough rule is: for every 10 feet of elevation change, adjust by about 1–2 yards per 10 feet.
Once you have the correct adjusted yardage, pick the club whose average carry distance matches. Don't guess — take note of how far you actually carry each club during your warm-up or on the range. Most beginners use longer clubs than needed and balloon the ball into trouble behind the green.
All yardage markers measure to the center of the green. Adjust based on where the flag is:
| Pin position | Adjustment from center marker | Club adjustment |
|---|---|---|
| Front of green | Subtract 5–15 yards | One club shorter |
| Middle of green | No change | Play the marker yardage exactly |
| Back of green | Add 5–15 yards | One club longer |
At most US courses, the 150-yard marker is white — a white stake or post positioned on the side of the fairway. However, courses are free to use any system they choose. Some use blue for 150, others use striped stakes. Always check the scorecard or ask the starter if you are unsure, especially on a course you have never played.
They measure the distance from that exact point in the fairway to the center of the putting green. "Center" is important — not the front edge, not the pin. Most courses use: red = 100 yards, white = 150 yards, blue = 200 yards. Stakes are placed on the edges of the fairway, so they measure to the center of the green from that lateral position — walk to the same distance on the fairway to get your true line yardage.
Walk to the nearest irrigation sprinkler head and look at the top — many have a number (like "145") stamped or stenciled on them. That number is the distance to either the center or the front of the green, depending on the course. The scorecard usually says which. Sprinkler heads are especially useful because they are exact — you know the yardage from that precise point on the ground, not "roughly" from a stake on the edge.
These stakes mark course boundaries and penalty areas — they are NOT yardage markers. White stakes mark out of bounds (OB), yellow stakes mark penalty areas (water hazards), and red stakes mark lateral penalty areas. These are very important to understand because going over these lines costs you penalty strokes. Confusing them with yardage markers is a common beginner mistake.
Most courses measure to the center of the green, but not all. Some measure to the front edge, especially sprinkler heads. This is always listed on the scorecard (look for "yardages measured to center of green" or "front of green"). If you are unsure, ask at the pro shop before your round — knowing which convention is used can easily be worth 1–2 clubs of difference.
Both are legal. GPS devices and rangefinders give you yardage from your actual ball position and can measure directly to the flag (if using a laser rangefinder). Course markers measure from a fixed point — you still need to know where your ball landed relative to that point. In practice, a rangefinder or GPS watch is more precise and faster, but if you don't have one, course markers plus mental adjustment work just fine for recreational play.
If there is no marker or sprinkler head within a few yards, you can walk to the nearest one and mentally add or subtract based on how many paces you walked. A golf stride is roughly 1 yard per pace. Count paces from the marker to your ball: if you walked 10 paces PAST a 150-yard marker toward the green, you are at approximately 140 yards. If you walked 10 paces AWAY from the green, you are at about 160 yards.
There is no worldwide rule requiring a specific color for 150-yard markers — that is just the most common convention in the US. Courses outside North America, older courses, or courses with unique branding may use different colors or symbols. The scorecard is the authoritative source: it should have a yardage legend or a note explaining which marker color corresponds to which distance on that specific course.
