Step 1
Grip putter of choice and point the putter to the sky with elbows close to your side.
Step 2
Bend from waist until putter is parallel to the ground.
Step 3
Allow arms to fall. Determine length and lie angle by toe of putter. Toe up = too long or too upright. Heel up = too short or too flat.
Step 4
Spread feet to shoulder width for a more accurate determination. Brow of nose should be just inside and behind the golf ball.
