What Is Attack Angle? Up With Driver, Down With Irons

What is attack angle?

Attack angle is whether the club head is moving upwards or downwards at the moment it reaches the ball. It is measured in degrees against the horizon, so a positive number means the club is travelling up and a negative number means it is travelling down.

It is the single clearest explanation for why the same swing produces a good drive and a thin 7-iron, because the two clubs need opposite numbers.

Key takeaways

• Positive is up, negative is down
• Driver wants positive, because the ball sits on a tee
• Everything off the turf wants negative, because you must reach the ball before the ground
• TrackMan put the LPGA Tour driver average at +2.8 degrees and the PGA Tour at -0.9
• Most amateurs hit down on the driver, which is the wrong direction for distance

The one rule that covers almost everything

Ball on a tee: hit up. Ball on the ground: hit down.

That is it, and it explains more bad shots than any other single idea in ball striking.

With a driver the ball sits above the turf, so there is nothing to catch behind it. Hitting up launches the ball higher with less spin, and higher with less spin is the recipe for carry. You are getting distance for free, without swinging any faster.

With an iron, a wedge or a fairway wood off the deck, the ball is sitting on the ground and the turf is directly behind it. You have to strike the ball first and the ground afterwards, which can only happen if the club is still descending. That is why a good iron divot starts in front of where the ball was.

Golfers who try to help the ball into the air with an iron are applying driver logic to a turf shot. The club bottoms out behind the ball, and the result is either fat or, after the body compensates, thin.

What the numbers actually look like

Tour averages

• PGA Tour: driver -0.9 degrees, 6-iron -3.7 degrees
• LPGA Tour: driver +2.8 degrees, 6-iron -2.3 degrees

Amateur averages with a driver

From TrackMan's Combine data.

Men

• Scratch or better: -0.9
• 5 handicap: -1.1
• 10 handicap: -1.2
• Average golfer, 14.5 handicap: -1.8
• Bogey golfer: -2.1

Women

• Scratch or better: -0.9
• 5 handicap: -1.8
• 10 handicap: -1.7
• 15 handicap: -2.3

Typical iron numbers

TrackMan's standard assumptions put a 6-iron around -3.2 degrees and a pitching wedge around -3.9, at normal club speeds and a mid trajectory.

The LPGA number is the interesting one

Look again at those two tour figures. LPGA players average plus 2.8 degrees with a driver. PGA Tour players average minus 0.9.

The shorter hitters are hitting up. The longer hitters are hitting down. That seems backwards until you understand what attack angle is actually buying you.

A positive attack angle adds launch and removes spin. For a player with moderate club speed, that combination is worth a lot of carry, because they need all the help they can get turning speed into flight. Hitting up is one of the few ways to gain distance without gaining speed.

A player swinging at 115 mph has so much ball speed that they can produce a good flight from a slightly descending strike, and many of them prefer the control it gives.

What this means for you. Almost every amateur in the data above is hitting down on the driver, and almost every amateur would benefit from not doing that. If you are a 14.5 handicap averaging -1.8 degrees, moving towards zero and then positive is distance sitting on the table. The LPGA number shows you what is possible.

How to move it in the right direction

With the driver, change your set-up before your swing.

• Tee it higher. You cannot hit up on a ball that is barely off the ground. Half the ball above the crown of the driver is a reasonable starting point.
• Move the ball forward, roughly off your lead heel, so the club reaches it after the bottom of the arc rather than before.
• Tilt your spine slightly away from the target at address, so your trail shoulder sits lower and your head is behind the ball. This is the one shot in golf where leaning back is correct.
• Keep your weight behind the ball through impact rather than drifting onto the lead side.

With irons, do the opposite of all of that. Ball nearer the centre, chest over or slightly ahead of the ball, weight a touch forward. Our guide to iron contact goes through those positions in detail, and it is the same geometry working the other way.

The mistake worth naming: a lot of golfers carry their driver set-up into their irons, or their iron set-up into their driver. Attack angle is where that shows up first.

Two things attack angle is not

It is not swing plane. Swing plane is the tilt of the whole swing. Attack angle is just the up-or-down direction in the few inches around impact. You can have a flat swing and still hit down.

It is not the same as low point, though they are related. Low point is where the bottom of your swing arc sits relative to the ball. Attack angle is how steeply the club is moving as it arrives. Two golfers can share an attack angle and have their low point in different places.

Does it actually matter to your score?

With the driver, genuinely yes. Moving from -2 degrees to +2 degrees changes your launch and spin enough to be worth real carry, and it costs nothing in effort.

With irons, the number matters less than people assume. Somewhere between about -2 and -5 degrees is a wide and perfectly playable range. What matters is that it is negative and that your low point sits in front of the ball. Chasing a specific iron attack angle is usually a distraction from chasing clean contact.

And if your driver attack angle is already positive, leave it alone and go and look at your strike location instead.

Measuring it at Grip

Attack angle is almost impossible to judge by feel, which is the whole problem. A swing that feels like it is lifting the ball is usually descending, and a swing that feels level is usually anything but.

Every bay at both our London studios runs Trackman 4, so attack angle is measured on every shot. The useful test takes ten minutes: hit ten drivers, note the average, raise your tee and move the ball forward, then hit ten more. Most golfers see the number move immediately, and seeing it move is what convinces you the change is real rather than imagined.

Deptford Park is our coaching home in SE8, with dedicated coaching bays where one of our professional coaches can put your set-up on video alongside the number. Tower Bridge gives members 24/7 access on a door code, which suits the short repeat sessions this kind of change needs.

For the direction half of your data rather than the vertical half, our guide to club path covers the same impact moment from the side, and the Trackman technology page explains the rest of what the system reads.

Book a session

Ball on a tee, hit up. Ball on the ground, hit down. Get those two the right way round and a surprising amount of your ball striking sorts itself out.

Book a free trial at Tower Bridge or Deptford Park and find out which way your club is actually moving. If you are hitting down on your driver, there is free distance waiting in a change that takes about two minutes to make.
