Understanding the Side Angle – Data & Statistics in Golf

In recent years, data, numbers, and metrics have become increasingly important in golf, and their significance continues to grow. On the PGA Tour, there are numerous statistics for each player, and the players themselves are well-versed in all the data, metrics, and parameters related to their swings, constantly working to optimize them.

The goal is to use data and metrics to measurably improve and optimize your game. With modern equipment like launch monitors, it’s very easy to generate a wealth of data points and metrics about your swing.

In addition to fitness, on-screen training already plays a very important role for professional golfers. But even as an ambitious amateur golfer, you can learn a lot from the data. First, however, you need to know and understand the key metrics. That’s what this is all about: we’ll explain the key metrics and parameters for golfers.

The side angle (also known as the azimuth) describes the horizontal launch angle of the golf ball immediately after impact. It indicates how many degrees to the left or right the ball starts relative to the target line.

Side Angles on the Launch Monitor

• 0.0° = The ball starts exactly toward the target
• + Side Angle = Ball starts to the right (push)
• – Side Angle = Ball starts on the left (Pull)

(for right-handed people; for left-handed people, the opposite applies)

What causes the side angle?

At the moment of impact, the side angle is determined almost entirely by the clubface angle.

Rule of thumb (scientifically proven):

The clubface determines approximately 75–90% of the direction of the shot

The shorter the club:

the more the clubface dominates

The longer the racket:

the greater the influence on the swing path

Example:

• Clubface 2° open
• Neutral swing path

➡️ The ball starts about 1.5–1.8° to the right with a side angle of +1.7°

Typical side-angle values

Practical application:
Even a 2° side angle results in a deviation of over 5 m at a 150 m carry—without a curve, i.e., on a straight pull or push!

Why Side Angle Is a Key Metric

For serious golfers, the side angle is an important factor because it:

• Technical error clearly separates
• Start Line Problems Explained Objectively
• shows whether Face Control or Path Control is the main issue

Motto:

“The side angle determines whether you have any chance of hitting the target at all—the curve just determines how you miss it.”
