- Out of bounds (white stakes) costs you stroke and distance — replay from where you last hit, adding one penalty stroke
- The "Model Local Rule E-5" lets you drop near where the ball went OB for two penalty strokes instead of walking back
- A ball is OB only if it is entirely beyond the boundary line — if any part touches the line, it's in bounds
- OB is the most punitive penalty in golf, often costing 2-3 strokes on a single hole
Out of bounds is golf's harshest penalty
Water hazards cost you one stroke. An unplayable lie costs you one stroke. But hitting your ball out of bounds? That costs you a stroke and your distance. You go all the way back, hit again, and you're essentially two strokes behind where you were.
Understanding exactly how OB works — and the local rule alternative that many courses now offer — can save you serious frustration and a few strokes per round.
How to identify out of bounds
Out of bounds is marked by:
- White stakes — the most common marker
- White lines — painted on the ground
- Fences, walls, or property boundaries — when designated by the course
- The course boundary as defined on the scorecard or course map
The boundary line runs along the inside edge (course side) of the stakes or fence posts at ground level. The stakes themselves are out of bounds.
Is the ball in or out?
A ball is out of bounds only when all of it is beyond the boundary line. If any part of the ball is touching or inside the line, it's in bounds. This is the opposite of penalty areas, where any part of the ball on the line means it's in the penalty area.
| Ball Position | Status |
|---|---|
| Entirely beyond the white stakes | Out of bounds |
| Sitting on the boundary line | In bounds |
| 99% over the line but 1% touching it | In bounds |
| Leaning against a white stake | Check from directly above — if any part is inside the line, it's in bounds |
The standard OB penalty: stroke and distance
Under the Rules of Golf, the penalty for OB is stroke and distance:
Add one penalty stroke to your score.
Go back to where you played your last shot and play again from there.
You are now hitting your third shot from that spot (if it was your tee shot) — stroke 1 (original shot) + penalty stroke + stroke 3 (replay).
Stroke count example
So a par-4 hole where your tee shot goes OB and everything else goes perfectly results in a double bogey (5 on a par 4). In practice, re-teeing under pressure often leads to triple bogey or worse.
Model Local Rule E-5: the alternative
Recognizing that stroke and distance can be extremely slow (the walk-back-and-re-hit process), the R&A and USGA introduced Model Local Rule E-5 in 2019. Many recreational courses have adopted it.
How E-5 works
Instead of going back to re-hit, you can drop near where the ball went OB — but it costs two penalty strokes instead of one.
Estimate where the ball crossed the OB line. This becomes your reference point.
Find the nearest fairway edge that is no closer to the hole than your reference point.
Drop within two club-lengths of the fairway edge, in the fairway or rough, no closer to the hole.
You are now lying 3 (if it was your tee shot): stroke 1 + two penalty strokes.
When to use E-5 vs. stroke and distance
| Situation | E-5 Result | Stroke & Distance Result |
|---|---|---|
| Tee shot OB, good re-tee likely | Lying 3 in the rough | Lying 3 on the tee (better position) |
| Tee shot OB, re-tee is risky | Lying 3 near the fairway | Lying 3 with another risky tee shot |
| Approach shot OB, near the green | Lying 4 near the green | Lying 4 back in the fairway |
The trade-off: E-5 costs one extra stroke (two penalties vs. one) but saves time and avoids the pressure of a re-hit. For most recreational golfers, E-5 is a great option.
E-5 is a local rule, not a universal rule. Check whether the course you're playing has adopted it — look on the scorecard, local rules sheet, or ask the pro shop. In formal competitions, E-5 may not be in effect.
OB vs. penalty area: know the difference
This is a common confusion point:
| Feature | Out of Bounds (White) | Penalty Area (Red/Yellow) |
|---|---|---|
| Penalty | Stroke and distance (or E-5) | One stroke |
| Can you play it as it lies? | No — it's out of play | Yes |
| Lateral drop option? | No (only with E-5 local rule) | Yes (red stakes) |
| Back-on-the-line drop? | No | Yes |
| Provisional ball allowed? | Yes | No |
The key takeaway: OB is much more punitive than a penalty area. This is why course designers use white stakes for out-of-play areas (property lines, roads, adjacent holes) and red/yellow stakes for in-play hazards.

How many strokes does OB really cost?
Let's look at the realistic cost of an OB tee shot on a par 4:
For a mid-handicapper who averages 2-3 OB shots per round, that's potentially 4-9 strokes lost to OB alone. Reducing OB frequency is one of the fastest ways to lower your score. Our guide to reducing penalty strokes breaks down the five fastest strategies for doing exactly that.
Strategies to avoid OB
Off the tee
- Know where OB is before you hit. Check the scorecard or look for white stakes. If OB is tight on the right, aim left of center.
- Club down. A 3-wood or hybrid off the tee reduces dispersion. Less distance, but more fairways.
- Pick your miss. If OB is left, set up to miss right. Accept a shot in the right rough over a disaster left.
On approach shots
- Be aware of OB behind and beside greens. Some holes have OB very close to the putting surface.
- Take enough club. Coming up short is almost always better than going long into OB.
Mental approach
- Don't steer the ball. Trying to guide the ball away from OB causes tension, which causes exactly the miss you feared.
- Commit to your target. Pick a line, trust your swing, and accept the result.
The provisional ball: your best friend
Whenever your ball might be OB, play a provisional immediately. Don't wait. Don't debate. The 30 seconds it takes to hit a provisional can save 10 minutes of walking back if you can't find your ball.
Say "I'm playing a provisional," hit your second ball, and walk forward. If you find the original in bounds, pick up the provisional. If it's OB, continue with the provisional.
For more details, see our complete provisional ball guide.
The bottom line
Out of bounds is golf's most punitive penalty — stroke and distance sends you back to replay your shot with a one-stroke penalty. The E-5 local rule offers a faster alternative (drop near the OB point for two penalty strokes) and is increasingly adopted at recreational courses. To minimize OB damage: know where the boundaries are before every shot, use less club when OB is tight, always play a provisional, and aim your misses away from white stakes.
References & Data Notes
OB rules are governed by Rule 18.2 of the Rules of Golf (R&A and USGA, 2023 edition, effective through 2026). Model Local Rule E-5 was introduced by the R&A and USGA in 2019 as an alternative to stroke and distance for recreational play. Stroke-loss estimates are based on general amateur scoring patterns.
