Putter Types Explained: Blade vs Mallet vs High-MOI

Your putter is the most-used club in the bag — and the one most golfers choose wrong. Here's how to match head design to your stroke type.

Putter Types Explained: Blade vs Mallet vs High-MOI

Why Your Putter Choice Matters More Than Your Driver

The average golfer takes 29-32 putts per round — roughly 40% of all strokes. Yet most players spend ten times longer researching drivers than putters. According to Arccos Golf data (based on millions of tracked rounds), putting accounts for more scoring variance among amateur golfers than any other shot type.

The putter market has exploded in the last decade. What was once a simple choice between a Ping Anser and a Bulls Eye has become a dizzying array of blade, mallet, high-MOI, face-balanced, toe-hang, insert, and milled options. But the core decision remains straightforward once you understand your stroke type.

Here's what most fitting guides won't tell you: there is no objectively best putter type. A $400 Scotty Cameron blade will perform worse for a straight-stroke golfer than a $150 Odyssey mallet that matches their mechanics. If you're building your full bag, start with our equipment roadmap.

The Three Putter Head Types

Blade Putters

The traditional putter design — compact, narrow, and heel-weighted. Blade putters have won more majors than any other type. Think Scotty Cameron Newport, Ping Anser, Odyssey #1.

Blades provide the most tactile feedback. You feel center vs mis-hit immediately. For skilled putters this feedback is valuable; for inconsistent putters, it's punishing.

Mallet Putters

Larger head with weight distributed toward back and perimeter. Range from semi-mallet (Odyssey #7) to full mallet (Odyssey 2-Ball, Cleveland HB SOFT).

High-MOI Putters

Oversized mallets engineered to maximize moment of inertia. Examples: Odyssey Ai-ONE, TaylorMade Spider GT Max, Ping Tyne G, Evnroll ER11.

What is MOI? Moment of Inertia measures resistance to twisting. Higher MOI = the face stays more stable on off-center hits. Since most amateurs miss the sweet spot by 0.5-1" (Quintic Ball Roll data), higher MOI translates to more made putts from 6-15 feet.

How to Identify Your Stroke Type

The Arc Stroke

Putter face opens slightly on backstroke, closes through impact. Tiger Woods, Jordan Spieth use arc strokes.

Best match: Blade or semi-mallet with moderate toe hang.

The Straight-Back-Straight-Through (SBST)

Minimal face rotation. Bryson DeChambeau uses this method.

Best match: Face-balanced mallets and high-MOI putters.

The Slight Arc (Most Common)

Most amateurs fall here. This is the most common stroke in club fittings.

Best match: Semi-mallets with slight toe hang (10-20°).

Insert vs Milled Face: Does It Matter?

Milled Face (Scotty Cameron, Bettinardi)

CNC-machined from a single block. Firmer "clickey" feel. Most direct feedback. Consistent ball speed when struck well.

Insert Face (Odyssey White Hot, TaylorMade Pure Roll)

Softer material (urethane/polymer) embedded in face. Dampens vibration and — crucially — produces more consistent ball speed on off-center hits. Cleveland research shows 15-20% less speed variance on mishits.

Bottom line: Rarely miss the sweet spot? Milled rewards precision. Average golfer? Inserts are more forgiving.

DIY Putter Fitting Tips

Length

Standard is 34-35". Under 5'8"? Try 33". Over 6'1"? Try 35". Eyes should be over or slightly inside the ball.

Grip Size

Larger grips (SuperStroke) reduce wrist action — good for "handsy" strokes. Standard grips give more feel.

The 6-Footer Test

Putt twenty 6-footers with each putter. Track makes. The one that sinks the most is right for your stroke. This distance is where design differences show most, per equipment testing.

Frequently Asked Questions

Are blade putters only for good golfers?

No, but they are less forgiving. Blades work best with arcing strokes. A 20-handicap with a natural arc may putt better with a blade than a high-MOI mallet that fights their mechanics.

What MOI do I need?

Most amateurs benefit from 5,000+ MOI. MyGolfSpy testing shows putters above 8,000 MOI retain 90%+ ball speed on mishits vs 70-75% for blades.

Face-balanced or toe-hang?

Straight stroke → face-balanced. Arc stroke → toe hang. Mismatching causes inconsistent face angles at impact.

How much should I spend?

Diminishing returns above $250. A $150 Cleveland performs nearly identically to a $400 Scotty Cameron in testing.
