Lie Angle Analysis

Computer-vision putter fitting, down-the-line. Put at the camera; the shaft's true angle to the ground becomes directly measurable.

What is lie angle?

The angle between your putter shaft and the ground at address. When it's wrong, the toe or heel lifts and the face aims offline — misses you compensate for without knowing it. Getting it right is the fastest fix in putting.

Set the scene

  1. Prop the phone on the ground facing you, roughly 6–9 ft away. Lens near grip height or lower.
  2. Turn and putt straight at the camera. Take three steps back from the phone, turn around, and set up as if the lens were the hole.
  3. Line the ball up on the plumb line. A dashed vertical guide appears on screen — put the ball on it, at your putter face, and take your address.
  4. Keep the phone upright. Use the plumb line against a fence post or door frame to check the phone isn't rolled to one side.
📐 Why down-the-line? Lie angle lives in the plane across your target line. From the side, a 65° and a 75° putter look identical — the view carries no lie information at all. Putting at the camera is the only setup where the shaft's true angle to the ground is visible.

Optional, but enables the scale cross-check — two independent measurements that verify each other.

How to measure wrist-to-floor

Stand naturally with arms hanging. Measure from the floor up to the crease on the back of your wrist. Record in inches or cm.
