What Is a GW in Golf?

By Spencer Lanoue
July 24, 2025

If you've ever glanced at a set of clubs and seen ‘GW’ stamped on the bottom, you're not alone in wondering what it stands for and, more importantly, what it does. The GW, or Gap Wedge, is one of the most important scoring clubs you can carry, but it’s often one of the most misunderstood. This article will explain exactly what a gap wedge is, why it's there to solve a very specific problem in your bag, and how you can use it to hit more shots closer to the pin.

What Exactly is a Gap Wedge (GW)?

A gap wedge - often abbreviated as GW - is a golf club designed to fill the yardage “gap” between your Pitching Wedge (PW) and your Sand Wedge (SW). Over the years, you may have also seen it labeled as an Approach Wedge (AW), Utility Wedge (UW), or simply with its loft, most commonly 50° or 52°.

Think of your wedges as a family of clubs built for precision and control inside 120 yards. Traditionally, that family included:

  • A Pitching Wedge (PW) for longer approach shots.
  • A Sand Wedge (SW) primarily for bunker shots and shorter pitches.

Decades ago, this simple setup worked perfectly. A standard pitching wedge had around 48 degrees of loft, and a sand wedge had about 56 degrees. The difference in loft was small enough that golfers could comfortably hit all their yardages. However, modern golf equipment has changed.

To give golfers more distance, club manufacturers started making irons with stronger lofts (meaning less loft). It’s not uncommon for a modern pitching wedge to have only 43-45 degrees of loft. Your trusty sand wedge? That's likely still sitting around 56 degrees. Suddenly, there’s a massive 11-13 degree loft difference between those two clubs, which can create a yardage gap of 20 to 30 yards. The gap wedge was born out of necessity to fill this void.

Do I Really Need a Gap Wedge?

For any golfer looking to improve their scoring and consistency, the short answer is yes. Picture this common scenario: you've hit a great drive and have 95 yards left to the flagstick. You pull out your rangefinder and know a full swing with your pitching wedge goes 110 yards. You also know that a full swing with your sand wedge only travels 80 yards.

What’s the play? Without a Gap Wedge, you have two imperfect options:

  1. Take something off the Pitching Wedge: You try a gentle three-quarter swing, but it’s a difficult feel-based shot to execute under pressure. Sometimes you’ll catch it too clean and fly the green. Other times you’ll decelerate and leave it 15 yards short. It’s a low-percentage play for most amateurs.
  2. Force the Sand Wedge: You swing extra hard with your sand wedge, hoping to squeeze another 15 yards out of it. This usually results in a rushed swing, poor contact, and an unpredictable ball flight. You might hit it fat, thin, or pull it way left.

This "in-between" yardage is exactly where the gap wedge shines. It allows you to make a smooth, confident, full-effort swing and trust that the club's loft will produce the right distance. It replaces guesswork with commitment, and commitment is the foundation of a good golf shot.

When and How to Use Your Gap Wedge

The beauty of a gap wedge is its versatility. While its primary role is for full swings, it’s an excellent tool for a variety of other shots that can help save you strokes around the green. Let's look at the most common uses.

1. Full Shots from the Fairway

As we discussed, this is the gap wedge's main duty. It's your go-to club for any approach shot that falls into that pesky yardage gap. For most male golfers, this will be in the 85 to 105-yard range. Because of its loft - higher than a PW but lower than an SW - it produces a high, arcing ball flight that lands softly on the green. This allows you to be aggressive and aim at pins, knowing the ball won't roll out excessively once it lands.

How to hit it: Treat it like any other iron. Play the ball in the middle of your stance, just as you would with a 9-iron or pitching wedge. Take your normal, balanced swing and trust the loft to do the work. Don't try to help the ball up or force a specific trajectory. A smooth, repeatable swing is all you need.

2. Delicate Pitch Shots (30-50 Yards)

A gap wedge is a fantastic option for longer pitch shots where you have some green to work with. Imagine you are 40 yards from the green. A sand wedge or lob wedge might fly high but stop very quickly, making it hard to get the ball all the way to a back pin. Conversely, a pitching wedge might come out too low and hot, running through the green.

The gap wedge offers the perfect middle ground. It produces a lower, more controlled flight than a sand wedge but has enough loft to provide a soft landing with a bit of check and a gentle release towards the hole. It's a highly predictable shot trajectory.

How to hit it: Narrow your stance slightly, put about 60% of your weight on your front foot, and make a controlled swing that feels like a third or half of your full swing length. Focus on accelerating through the ball to create clean contact.

3. Controlled "Bump-and-Run" Chips

For chipping, controlling roll-out is everything. When you’re just off the green, a sand wedge can sometimes pop up too high and check up short of the hole, while an 8 or 9-iron might roll out too far. The gap wedge fits in here beautifully. It provides enough loft to easily carry the fringe or a bit of rough, but not so much that it kills all forward momentum.

How to hit it: Play the ball back in your stance slightly, keep your hands ahead of the clubhead, and use a simple, stable "putting-style" stroke. Your goal is to land the ball a few feet onto the green and let it release and roll like a putt the rest of the way to the hole.

4. Specific Bunker Situations

While the sand wedge, with its typically higher bounce, is purpose-built for most greenside bunkers, a gap wedge can be very effective in certain situations. If you're in a fairway bunker needing to carry the ball 100 yards, a gap wedge is a great choice as it will give you more distance than an SW. It’s also very useful from greenside bunkers with very firm, compacted sand where the higher bounce of a sand wedge might cause the club to skim off the sand instead of digging in.

A word of caution: For average golfers playing from soft, fluffy sand, stick with your sand wedge. Its design is meant to help you slide the club under the ball with ease.

Choosing the Right Gap Wedge for Your Game

Adding a gap wedge to your bag is a smart move, but picking the right one requires a little thought. You want to ensure it creates a consistent and uniform progression in your set. Here’s a simple, step-by-step approach.

Step 1: Find the Loft of Your Pitching Wedge

The first and most important step is to know the loft of your current pitching wedge. This is the cornerstone of your entire wedge setup. If it’s not stamped on the clubhead itself, a quick online search for your iron set's specific model and year will give you the specs.

Step 2: Know the Loft of Your Sand Wedge

Next, identify the loft of your sand wedge. The most common lofts are 54°, 56°, and 58°. Just like the PW, this loft is almost always stamped directly on the club.

Step 3: Apply the "4 to 6 Degree" Rule

Golf coaches and club fitters generally recommend spacing your wedges out by 4 to 6 degrees of loft. This typically creates a manageable 10 to 15-yard distance gap between each club, which is exactly what you want.

Let's use a real-world example:

  • Your Pitching Wedge is 44°.
  • Your Sand Wedge is 56°.

The total loft gap between them is 12 degrees (56 - 44 = 12). To fill this, a 50° gap wedge would be the perfect fit. Your wedge progression would then be 44°, 50°, and 56° - a perfect 6 degrees between each club. If your PW was 45° and your SW was 54°, a 49° or 50° GW would fit perfectly.

Step 4: Think About Bounce (But Don't Overthink It)

Wedge "bounce" is the angle of the club's sole from the leading edge to the trailing edge. In simple terms, it's what helps the club interact with the turf or sand without digging in too much.

  • High Bounce (12°+): Best for soft turf, fluffy sand, and for golfers with steep attack angles (who tend to take big divots).
  • Low Bounce (4°-8°): Best for firm turf, hardpan lies, and for golfers with shallow attack angles (who tend to "sweep" the ball).

For a gap wedge, a mid-bounce option (around 8° to 12°) is usually the most versatile and a safe bet for the majority of golfers and course conditions.

Final Thoughts

The gap wedge is far more than just another club, it's a dedicated scoring tool designed to solve a very specific problem that holds many golfers back. Adding the right one to your bag armed with the knowledge of how and when to use it will remove guesswork, build confidence, and ultimately help you post lower scores.
