Peak Height in a Driver Fitting

Peak height confirms how high the ball actually flew. The engine uses it to check whether launch and spin produced a playable flight window.

What is Peak Height?

The apex of the shot trajectory, used to judge whether launch, spin, and ball speed are producing a playable flight window. For a fitting, the important part is how this number connects to the rest of the shot pattern, not whether it looks good by itself.

Field	Meaning
Technical definition	Peak Height is the maximum height the golf ball reaches above the launch elevation during its flight.
Common launch monitor labels	FlightScope: Apex Height; TrackMan: Height (Apex)
Typical unit	yards/metres or feet/metres
Role in Smart Golf Fitting	Optional flight-window signal

How does Smart Golf Fitting use Peak Height?

Peak height is optional. When present, it strengthens the flight-window read: high peak with high spin can support low-spin family direction, while low peak with low launch can support more launch help and soften low-spin recommendations.

Confirms whether the flight is too high, too flat, or playable.
Supports low-spin heads when high spin also produces a high flight.
Supports launch-help direction when the flight is flat.
Improves hosel loft-up confidence when height is poor.

Which related launch monitor metrics should be checked with Peak Height?

Peak Height becomes useful when it is read beside the numbers that explain its cause or its outcome. These relationships are what stop a fitting from chasing one attractive number while making the full shot pattern worse.

Related metric	How the relationship works
Launch Angle	Launch angle is the start of the flight; peak height is what the flight became. Peak height confirms whether the launch number created enough playable height.
Spin Rate	Spin can help the ball climb or make it balloon. Peak height confirms whether the spin number is creating a useful flight or too much height.
Ball Speed	Ball speed gives the flight enough energy to climb. Peak height shows whether that energy created a playable window or a flight that was too flat or too high.
Carry Distance	Peak height helps explain carry. A flight that never climbs enough may leave carry short even when ball speed looks reasonable.
Descent Angle	Peak height usually influences descent angle. A ball that climbs higher often lands steeper, while a flatter peak tends to produce more rollout.

What can be misleading about Peak Height?

Peak height cannot be judged without club type and ball speed. A driver and wedge can have similar apex heights but very different flight shapes and landing behaviours.

What does the engine do when Peak Height looks unusual?

Peak height should not be judged by one universal target. The same height can be strong for one speed band and weak for another.

First check

Check whether height is caused by launch, spin, or speed, then adjust loft, head model, shaft profile, or set make-up accordingly.

Fitting principle

The engine looks for agreement across the full shot pattern before changing the recommendation. If the related metrics do not support the same story, the report stays more conservative.
