Every launch monitor number, explained

How fast the ball leaves the face immediately after impact.

Why it matters. The single biggest driver of distance — more ball speed is more potential carry. It's club speed multiplied by strike quality (smash).

TrackMan driver ball speed: ~171 mph PGA Tour, ~161 for a scratch amateur, ~132 for a 15-handicap.

How fast the ball is spinning backward as it leaves the face.

Why it matters. Backspin controls how high the ball climbs, how long it holds the air, and how it stops. Too little and drives fall short; too much and they balloon. It's a window, not 'lower is always better'.

TrackMan driver spin: ~2,545 rpm PGA Tour, ~2,900 for a scratch amateur, ~3,275 for the average golfer; irons and wedges spin far higher (a wedge is ~8,000–11,000 rpm).

The tilt of the ball's spin. A right-tilted axis curves the ball right (for a right-hander); level is straight.

Why it matters. Curvature comes from the spin axis, not a separate 'side spin' force. It's the truest read on why a ball drew, faded, or fought sideways.

Curvature scales with tilt: a few degrees of axis is a gentle shape; large tilts are a slice or hook. Derived from face-to-path at impact.

How fast the clubhead is travelling through impact.

Why it matters. Sets the ceiling for ball speed and distance. Radar units measure it directly; camera units without club tracking infer it from ball speed.

TrackMan driver club speed: ~113–118 mph PGA Tour, ~93 mph for the average male amateur (~14 handicap).

Benchmarks from TrackMan

Ball speed divided by club speed — a measure of strike efficiency.

Why it matters. Tells you how much of your speed is reaching the ball. Off-centre strikes and poor delivery bleed smash; it's the cleanest read on contact quality.

TrackMan driver smash tops out near 1.50 (Tour ~1.48–1.50); a 14-handicap averages ~1.44. Higher-lofted clubs run lower (a wedge is ~1.15–1.25).

The horizontal direction the clubhead is moving through impact — in-to-out (+) or out-to-in (−).

Why it matters. Path plus face angle explains every shot shape. Path is the second half of the face-to-path relationship that sets curvature.

Together with face angle, path resolves to face-to-path → the ball's curve.

Benchmarks from TrackMan

Where the clubface points at impact relative to the target — open (+, right) or closed (−).

Why it matters. Face angle sets ~85% of your start line and dominates curvature. It's usually the real culprit behind a miss — often more than path.

Roughly 85% of start line; the primary lever on shot shape.

Benchmarks from TrackMan

The face angle measured relative to the club path — the difference between the two.

Why it matters. This single number is the cause of curvature: face open to the path fades, closed to the path draws. The cleanest diagnostic for shot shape.

Face open to path → fade/slice; closed to path → draw/hook. Zero = straight (a push or pull along the path).

Benchmarks from TrackMan

Whether the clubhead is moving up (+) or down (−) through impact.

Why it matters. Drives launch and spin, and whether you compress irons or hit up on the driver. Hitting up on driver adds distance; hitting down on irons is compression.

Tour hits up on driver (~+3° to +5° is a common goal) and down on irons (a descending strike).

Benchmarks from TrackMan

The actual loft delivered to the ball at impact (not the loft stamped on the club).

Why it matters. Dynamic loft, with attack angle, is what really sets launch and spin. Adding or de-lofting the face at impact changes flight more than the static loft.

Dynamic loft minus attack angle ≈ spin loft, which drives spin.

Benchmarks from TrackMan

The angle between the club's dynamic loft and its attack angle — the true 'gap' the ball climbs.

Why it matters. Spin loft is the master control on spin: bigger spin loft means more spin and less ball speed. Managing it is how you flight the ball and control distance.

Larger spin loft → more spin, lower smash; the core trade-off in ball-striking.

Benchmarks from TrackMan

Where on the face the ball made contact — toe/heel and high/low.

Why it matters. Strike location explains smash, spin, and gear-effect curvature. Only camera/photometric units that track the club can see it; radar units cannot.

Toward the toe/heel adds gear-effect curve; low strikes add spin, high strikes lose it.

Benchmarks from TrackMan

The vertical angle the ball climbs on immediately after impact.

Why it matters. With spin, launch angle sets your trajectory and carry window. Optimal launch depends on speed — slower swingers generally want to launch it higher.

TrackMan driver launch: ~10–12° is a common optimal window for amateurs; higher lofted clubs launch higher.

Benchmarks from TrackMan

The horizontal direction the ball starts, relative to your target line.

Why it matters. Start line is roughly 85% face angle at impact — so a ball starting well offline is a face problem, and it's the first half of the two-part face/path shot-shape story.

Start line tracks face angle at impact (roughly an 85/15 face-to-path split).

Benchmarks from TrackMan

The highest point the ball reaches in its flight.

Why it matters. A read on trajectory and how the ball will land — higher apex generally stops faster. Ties launch and spin together into one number.

Tour driver apex is often ~30+ yards; peak height rises with launch and spin.

Benchmarks from TrackMan

The angle the ball is coming down at when it lands.

Why it matters. Steeper descent stops the ball faster and holds greens; shallow descent runs out. Key for whether an approach will hold.

Comes from apex + spin; steeper with more height and spin.

Benchmarks from TrackMan

How far the ball travels through the air before its first bounce.

Why it matters. The number that actually matters for gapping and club selection — total distance depends on turf and roll, but carry is repeatable. Radar measures it; camera units model it from launch conditions.

Shot Scope carry by handicap — driver ~250 yd (scratch) to ~195 (20-hcp); 7-iron ~165 to ~130. Modelled carry on camera units assumes standard conditions.
