Spin loft is defined as the three-dimensional angle between the path of the clubhead and the face angle at impact. Dynamic loft refers to the vertical angle of the club face at impact, while angle of attack is the vertical direction of the clubhead's movement. To determine spin loft, one takes the dynamic loft and subtracts the angle of attack. A higher spin loft leads to more backspin and better shot consistency compared to just hitting down more on the ball.

2. Definition - Spin Loft
• Spin loft is the three-dimensional angle between the
direction the club head is moving (both club path and
attack angle) and the direction the club face is pointing
(both face angle and dynamic loft). - Trackman

4. What Is Dynamic Loft?
• Dynamic Loft is represented by
the yellow line
• Dynamic loft is the vertical angle
of the club face at the center-
point of contact between the club
and ball at the time of maximum
compression. Dynamic Loft is the
amount of loft on the club face at
impact and is measured relative
to the horizon. - Trackman

5. What Is Angle Of Attack?
• Angle of Attack is represented
by the downward blue arrow
• Angle of Attack is the vertical
direction of the club head’s
geometric center movement
at maximum compression of
the golf ball. - Trackman

6. How To Determine Spin Loft?
• The equation to determine spin loft is:
Dynamic Loft-Angle of Attack=Spin Loft
Now plug in the values into the equation:
X - (-5*) = 20*
Dynamic Loft-Angle of Attack=Spin Loft
Dynamic loft is equal to 15*

7. Matters Spin Loft Has Explained To Us
• Hitting down more does NOT equate to more spin…
Increasing the spin loft does.
• The reason a flatter faced club (such as a driver) is more
difficult to hit is due to the lack of spin loft making it
easier to change the spin axis.
