A putter fitting is a process where a golfer's putting stroke and preferences are analysed to determine the best putter for their individual needs. During a putter fitting, a fitter will typically evaluate the following using SAM PuttLab:

1. Stroke type: The fitter will observe the golfer's putting stroke, including their backswing, downswing, and follow-through, to determine their dominant stroke type (e.g. straight back and through, arcing, etc.).
2. Face angle: The fitter will evaluate the golfer's face angle at impact to determine if they have a square, open, or closed face at impact.
3. Lie angle: The fitter will measure the golfer's lie angle to ensure that the putter is set at the correct angle to the ground.
4. Length: The fitter will measure the golfer's arm length and posture to determine the optimal length of the putter.
5. Weight: The fitter will evaluate the golfer's preferred weight of the putter.
6. Look and feel: The fitter will analyse the golfer's personal preference on the look and feel of the putter.

Based on these evaluations, the fitter will recommend a putter that best matches the golfer's individual needs.
