What Is a Driver in Golf?

By Spencer Lanoue
July 24, 2025

The golf driver, often called the Big Dog, is the most powerful club in your bag, designed for one primary mission: hitting the ball as far as possible down the fairway. It’s the club you’ll typically use to start on par 4 and par 5 holes, setting the stage for the rest of the hole. This guide will walk you through exactly what a driver is, how to set up to hit it properly, and the fundamental swing thoughts that will help you unleash its incredible distance potential with confidence.

What is a Driver? The 'Big Dog' Explained

At its heart, a driver is a specialized wood built for speed and distance. It stands out from every other club in your bag because of a few distinct characteristics:

  • The Longest Shaft: Drivers feature the longest legally permitted shaft, usually ranging from 44 to 46 inches. This length creates a wider swing arc, which translates directly into more clubhead speed - the primary ingredient for distance.
  • The Largest Clubhead: Drivers have the biggest head of any club, with modern ones maxing out at the legal limit of 460 cubic centimeters (cc). This massive size allows for a large, forgiving face, making it easier to make solid contact even on slight mishits.
  • The Lowest Loft: Loft is the angle of the clubface relative to a vertical line. Drivers have the lowest loft in the bag, typically between 8 and 12 degrees. This low angle helps produce a lower-spinning, penetrating ball flight that maximizes roll-out and overall distance.

When you combine these three elements - a long shaft for speed, a large head for forgiveness, and a low loft for a powerful flight - you get a club engineered to be a pure distance machine. However, these same traits also make it the most challenging club for many players to control. The long shaft can feel awkward to swing, and the low loft is less forgiving on poorly struck shots, often exaggerating slices or hooks. That’s why understanding its design is the first step toward taming it.

The Anatomy of a Modern Driver

To really get a feel for how a driver works, it helps to understand its individual parts. Think of it less as a single piece of equipment and more as a system of components working together to send your golf ball soaring.

The Clubhead

The head is the engine of the driver. Modern driver heads, usually made from lightweight and strong titanium, are marvels of engineering. The perimeter of the head is weighted to increase the an idea known as the Moment of Inertia (MOI). High MOI simply means the clubhead is more resistant to twisting on off-center hits. If you strike the ball on the toe or heel, a forgiving, high-MOI head will twist less, helping the ball fly straighter and lose less distance. This is where the 460cc size really helps - it gives engineers a ton of real estate to push weight to the edges and maximize forgiveness.

The Shaft

If the clubhead is the engine, the shaft is the transmission that delivers the power. The most important characteristic of a driver shaft, aside from its length, is its flex. Shaft flex refers to how much the shaft bends during the swing. It’s typically categorized into: Extra Stiff (X), Stiff (S), Regular (R), Senior (A), and Ladies (L).

Choosing the right flex is about matching it to your swing speed. A faster swing needs a stiffer shaft to keep the clubhead stable and deliver it squarely to the ball. A slower, smoother swing benefits from a softer flex, which helps "kick" through impact to generate extra speed. Playing a shaft that’s too stiff for you can result in a loss of distance and shots that tend to go low and to the right (for a right-handed golfer). Playing one that’s too soft can lead to a feeling of 'looseness' and shots that fly high and left.

The Loft

As we mentioned, the driver’s low loft is built for distance, but you have options. Many golfers, especially beginners, make the mistake of thinking a lower loft (like 8 or 9 degrees) is for "better" players. In reality, a bit more loft can be your best friend. A higher loft (10.5 or 12 degrees) makes it easier to get the ball airborne, promotes a higher launch, and can actually reduce the sidespin that causes slices. Don’t let your ego choose your loft, choose the one that gives you the most consistent, playable drives, not just the occasional bomb.

Setting Up for Success: How to Tee It Up and Address the Ball

A great drive begins before you even start your swing. The setup for a driver is fundamentally different from an iron. With an iron, you are trying to hit down on the ball. With a driver, your goal is to hit slightly up on the ball, sweeping it off the tee at the bottom of your swing arc. Your entire setup should be built to encourage this ascending angle of attack.

Step 1: Get the Tee Height Right

This is the first and perhaps simplest adjustment. When you place your driver head next to the teed-up ball, roughly half of the ball should sit above the top line (or crown) of the driver. This elevated position is what allows you to make contact as the club is traveling upward, which is the key to launching the ball high with low spin for maximum distance.

Step 2: Position the Ball Forward

Unlike an iron, which is played near the center of the stance, the driver needs to be played far forward. Place the teed-up ball so it’s in line with the heel or armpit of your lead foot (your left foot for right-handed players). This forward position ensures that by the time your clubhead reaches the ball, it has already passed the lowest point of its arc and is on the way up.

Step 3: Widen Your Stance

Your swing with a driver is your fastest, most powerful swing. To support that, you need a stable foundation. Widen your stance so your feet are about shoulder-width apart, or even slightly wider. This gives you the solid base you need to rotate your body powerfully without losing your balance.

Step 4: Establish Spine Tilt

This is the final and most important piece of the setup puzzle. To promote that upward swing, your upper body needs to be tilted slightly away from the target. From your address position, imagine your spine tilting a few degrees to the right (for a righty), so your lead shoulder feels slightly higher than your trail shoulder. A great way to feel this is to stand in your setup, take your trail hand (right hand) off the club, and slide it down your trail leg a few inches towards your knee. That simple move will tilt your spine correctly and put you in a perfect position to launch your drive.

The Driver Swing: Your Key Swing Thoughts

With a solid setup, the swing itself becomes much simpler. You've already put your body in a position to do the right things. Now, it's about making a free, athletic move.

A Big, Smooth Turn

Think "wide and smooth" on your backswing. As you rotate your torso away from the ball, feel like you're creating as much space as possible between your hands and your chest. The goal is to fully rotate your shoulders and hips around your spine, coiling up like a spring. A lot of golfers focus on just their arms, but the power in the golf swing is created by the body. Let your arms just go along for the ride created by your body's turn.

Unwind from the Ground Up

Starting the downswing is all about sequence. You want to unwind the power you’ve stored up, starting with your lower body. The feeling is a slight shift of weight to your lead foot, followed by the unwinding of your hips. This action pulls your torso, shoulders, and finally your arms and the club down into the ball. Trying to hit with just your arms and hands leads to an 'over the top' move and that dreaded slice. Let your body be the engine.

Sweep, Don't Hit

Your main swing thought through impact should be to "sweep the ball off the tee." Forget about forcefully hitting at the ball. Because your setup has put you in the perfect position, all you need to do is continue your body's rotation through the ball. The club will naturally find its way back to the ball on a shallow, ascending path. This feeling frees you up to make a powerful, unrestrained swing instead of a tight, anxious one.

Final Thoughts

The driver might seem intimidating, but it follows a clear set of principles. By understanding it's built for distance, adopting a setup that specifically promotes an upward strike, and trusting a full body rotation, you can turn the most challenging club in your bag into one of your greatest assets on the course.

Of course, knowing *how* to hit a driver is only half the battle, knowing *when* to hit it is just as vital. Standing on a tight par 4, unsure if the "Big Dog" is the smart play, can destroy commitment.

Having that confidence and a clear plan helps you make a committed, athletic swing, every single time.
