To determine your putting stroke type, observe the path your putter head follows during your stroke. Using a mirror can be helpful to see the path of your club. Alternatively, you can video tape your swing so you can watch the stroke from behind.
If it moves directly back and forth along a straight line, you likely have a straight-back, straight-through putting stroke. Conversely, if your putter head follows an arc, curving slightly inside or outside your target line, you likely have an arching putting stroke.
You can further confirm your stroke type by assessing your tendencies for face rotation during the stroke—minimal rotation indicates a straight-back, straight-through stroke, while more rotation suggests an arching stroke. Understanding your putting stroke type is crucial for selecting the right putter design and fitting to enhance your putting performance.
