Center of Gravity
Center of gravity (CG) is the single point inside a golf club head where its weight is balanced in every direction. Where that point sits changes how high the ball launches, how much it spins, and how forgiving the club feels.
What is a center of gravity in golf?
In golf, “center of gravity” almost always describes the balance point of a club head. Tom Wishon, a longtime club designer, defines it as the point where all the possible balance points of an object intersect. Balance a driver head on its face, then on its sole, then on its toe, and the spot where those balance lines cross inside the head is the CG.
That point is fixed by where the weight sits. A taller head or extra mass near the crown raises the CG; a shallow head or weight along the sole drops it. Because the point lives in three dimensions, designers describe it three ways: how high it is from the sole, how far back it is from the face, and how close it is to the shaft.
The same term sometimes refers to a golfer’s own balance during the swing, meaning the point where body weight is centered as it shifts from backswing to follow-through. Both meanings come from the same physics, but a reader who runs into “CG” in a club review or a fitting session is reading about the club head.
How center of gravity affects ball flight
CG location is one of the reasons two drivers with the same loft can fly completely differently. Where engineers place the weight decides the launch and spin a club tends to produce, which is why a single driver model can be sold as “low spin” or “high launch.” The position works along three axes.
Low versus high CG
A lower CG sits closer to the sole. It helps the face get under the ball at impact, so the shot launches higher and spins a little less. A higher CG does the opposite: a lower, more penetrating flight with more spin. This is why fairway woods and game-improvement irons push weight low, and why control-oriented irons sit a touch higher.
Forward versus back CG
CG depth, how far the point sits from the face, is the lever modern driver design pulls hardest. A forward CG (toward the face) cuts spin and lowers launch, which adds rollout and distance for a fast, descending strike, but it leaves less margin on mis-hits. A rearward CG (toward the back) raises launch and spin and makes the club more stable on off-center contact. According to GOLF.com’s Gear 101 series, Tiger Woods’s former TaylorMade M5 driver was built with a forward, heel-biased CG to produce a low draw.
Heel versus toe CG
Side-to-side position matters too. Wishon explains that the closer the CG sits to the shaft, the easier it is for a golfer to square or close the face by impact, which reduces the tendency to push or fade. The farther the CG moves toward the toe, the harder the face is to close, so the ball is more likely to leak right for a right-handed player.
| CG position | Launch | Spin | General feel |
|---|---|---|---|
| Low | Higher | Lower | Easier to get airborne |
| High | Lower | Higher | More penetrating, more control |
| Forward (near face) | Lower | Lower | Less forgiving, more rollout |
| Back (away from face) | Higher | Higher | More forgiving, more stable |
Center of gravity vs moment of inertia (MOI)
CG and moment of inertia get mentioned in the same breath, and they are easy to confuse. CG is a location, the balance point. MOI is a measurement of how much a club head resists twisting when the ball strikes away from that point. The two are linked: pushing weight low and back, away from the face, usually raises MOI, which is why “low and back” designs feel both higher-launching and more forgiving.
| Center of gravity (CG) | Moment of inertia (MOI) | |
|---|---|---|
| What it is | A point (the balance point) | A number (resistance to twisting) |
| Mainly affects | Launch and spin | Forgiveness on mis-hits |
| Designers chase | Optimal placement | A higher value |
How center of gravity differs across clubs
Drivers see the most attention, partly because their large heads leave room to move weight around. Many modern drivers carry sliding or swappable sole weights that let a fitter shift the CG forward, back, or toward the heel or toe. As a rule, a low and back setting suits most golfers because it launches high and forgives mis-hits, while stronger players sometimes prefer low and forward for less spin.
Irons and wedges usually have a CG that is set in the design and cannot be moved. Many sets are built with a progressive CG: lower in the long irons to help them climb, and gradually higher through the short irons and wedges, where the ball is often struck higher on the face. A reader does not need to track these positions to play, but it explains why a 4-iron and a pitching wedge from the same set behave so differently.
MyGolfSpy’s testing adds a useful reality check on the marketing. Across the drivers it measured, every CG fell inside a box roughly 14mm front-to-back and 12mm top-to-bottom, about the size of a microSD card. The advertised graphics that show weight sliding from the rear of a head all the way to the face overstate how far the point actually travels.

Frequently Asked Questions
Where is the center of gravity on a golf club?
It sits inside the club head, usually close to the geometric center but shifted by where the designer places mass. Drivers tend to have it low and toward the back; blade irons sit higher and more forward.
Is a low or high center of gravity better?
Neither is better in every case. A low CG launches the ball higher with less spin and suits most amateurs, while a higher CG gives a flatter, more controlled flight that stronger players often want in their irons.
Can the center of gravity of a club be changed?
On many drivers and some fairway woods, yes, using adjustable sole weights. On most irons and wedges, the CG is fixed by the design and cannot be moved.
Does center of gravity affect distance?
Indirectly. By shaping launch and spin, CG position changes how efficiently a shot carries and rolls. A forward CG that lowers spin can add rollout, while a low, back CG can help a golfer carry the ball farther through the air.
