Grip putter of choice and point the putter to the sky with elbows close to your side.

Bend from waist until putter is parallel to the ground.

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.

Spread feet to shoulder width for a more accurate determination. Brow of nose should be just inside and behind the golf ball.
