Four Specs Decide Whether a Putter Suits You
Length, lie, head weight and balance. Head shape is the fifth, and it matters considerably less than the marketing around it suggests.
-
Length, read off your eye line
We drop a plumb line from your eye at address and see where it falls relative to the ball. Inside the ball and you are standing too close for the length you are holding; well outside and the putter is too short. Almost every putter sold off a rack is longer than the player needs, because off-the-rack length is set for convenience of stocking rather than for people.
-
Lie, so the sole sits flat at impact
A putter whose toe or heel is off the ground at impact starts the ball offline before the face angle has any say in it. Sole tape and a roll surface show this in a handful of strokes, and lie is adjustable on most heads.
-
Head weight, matched to green speed
Slow, grainy greens want a heavier head to keep the stroke moving. Fast greens want less, so the stroke can stay small and controlled. Local greens run quick through the dry months and slow down markedly after the monsoon weeks, so we usually fit a head weight that suits the faster end and discuss a counterweight for the softer part of the season.
-
Balance, matched to your actual arc
The amount the face rotates through your stroke is a physical fact we measure rather than a style you choose. A stroke with a pronounced arc wants a head that hangs toe-down; a stroke that travels nearly straight wants one that balances face-up. Getting this backwards fights the player on every putt and is the single most common mismatch we find.
Grip Size Is a Fitting Variable Too
A larger putter grip reduces how much the hands can rotate the face. That helps a player whose misses come from an inconsistent face angle, and hurts a player who relies on feel for pace. It is not a fashion decision and it should not be made from a display rack.
We test three sizes on the same head and count where the ball starts and how far it finishes from a target distance. The one that wins is the one you take, regardless of which one looks right.
The Roll Surface, and Why It Is Cut Short
The indoor roll surface is kept at a speed close to what the better-conditioned public greens run around here in June. A putter that behaves well on a slow carpet is not evidence of anything, and fitting on one produces heads that feel dead on the course.
Bring your gamer. Even if you are certain you want to replace it, the putter you have been using is the reference every comparison runs against, and its specs frequently explain a habit you did not know you had.
Loft and Shaft Lean
Putters have loft, usually around three degrees, to lift the ball out of its small resting depression and get it rolling. A player who presses the handle forward removes that loft and drives the ball into the green, producing a skid before the roll starts. Adjusting putter loft to match how you deliver the handle is cheap, quick, and almost never done.
Most Putter Fittings End With an Adjustment, Not a Purchase
Length, lie and loft are all adjustable on the club you already own more often than not.
