What Is High MOI in a Putter?

MOI, or Moment of Inertia, is a measurement of a putter’s resistance to twisting upon impact. A high MOI putter is designed to remain stable even on off-center strikes, helping golfers maintain better direction and distance control.

How Is MOI Measured in a Putter?

MOI is measured in grams per centimeter squared (g/cm²) or grams per millimeter squared (g/mm²), depending on the manufacturer. It quantifies how much force is required to rotate the clubhead around its center of gravity.

A higher MOI value means the putter is less likely to twist, leading to improved stability on off-center hits.

How Manufacturers Increase MOI:

1. Perimeter Weighting – Moving weight to the edges of the putter head increases MOI.
2. Multi-Material Construction – Using lightweight materials (like aluminum) in the center and heavier materials (like tungsten or steel) around the edges boosts stability.
3. Wider or Mallet Designs – Larger putters naturally distribute weight more effectively, increasing MOI compared to blade putters.

How Do Golfers Benefit from a High MOI Putter?

High MOI putters are particularly beneficial for golfers who struggle with consistency in their stroke. Key benefits include:

1. More Forgiveness on Mishits – A high MOI putter resists twisting, ensuring that even off-center strikes stay on line.
2. Improved Distance Control – Less energy loss on off-center hits means putts travel more consistently.
3. Enhanced Stability Through Impact – High MOI putters stay square to the target longer, leading to fewer pulled or pushed putts.
4. Better Performance Under Pressure – When nerves affect stroke quality, a high MOI putter provides extra margin for error.

What Is an Ideal MOI for a Putter?

There is no single “ideal” MOI number, as it depends on a golfer’s stroke type and preferences. However, here are some general guidelines:

• Low MOI (2,500 – 4,000 g/cm²): Traditional blade putters, best for golfers with an arc stroke.
• Mid MOI (4,000 – 5,500 g/cm²): Balanced putters offering a mix of forgiveness and feel.
• High MOI (5,500+ g/cm²): Mallet-style putters designed for maximum stability and straight-back, straight-through strokes.

For reference, some of the most stable putters today exceed 6,000 g/cm², such as the TaylorMade Spider or Odyssey Ten series.

Here are five putters with the highest MOI available today, designed for maximum forgiveness and stability:

1. TaylorMade Spider GT Max

• MOI: ~6,000+ g/cm²
• Why It’s High MOI: Multi-material construction with tungsten weight bars on the perimeter and adjustable weighting system for stability.
• Best For: Golfers who want customization in weighting while maintaining extreme forgiveness.

2. Ping Heppler Tomcat 14

• MOI: ~6,300 g/cm²
• Why It’s High MOI: A large, multi-material mallet with a steel and aluminum body, increasing perimeter weighting.
• Best For: Players needing extra stability and alignment help with a high-contrast design.

3. Odyssey Ten Triple Track Putter

• MOI: ~6,000+ g/cm²
• Why It’s High MOI: A massive mallet design with a White Hot insert and a multi-material head that boosts weight distribution.
• Best For: Golfers who want an ultra-stable putter with built-in alignment features.

4. Evnroll ER11V Mallet

• MOI: ~6,000 g/cm²
• Why It’s High MOI: Uses tungsten weighting on the edges and features Evnroll’s patented groove technology for added consistency.
• Best For: Players who want forgiveness with precision-milled face tech for better roll consistency.

5. PXG Battle Ready Blackjack

• MOI: ~5,800+ g/cm²
• Why It’s High MOI: Heavy tungsten weighting and a deep, stable head design reduce twisting on off-center strikes.
• Best For: Golfers who want an aggressive, modern design with extreme stability.
