Choosing the right golf shaft flex is crucial for any golfer, especially beginners. The flex of a golf shaft affects the performance, feel, and accuracy of your shots. Understanding the differences between stiff and regular flex can help you make an informed decision that enhances your game.

Importance of Choosing the Right Shaft Flex

The flex of your golf shaft determines how much it bends during your swing. The right flex can improve your accuracy, distance, and overall performance, while the wrong flex can lead to inconsistent shots and frustration on the course.


In this guide, we will explore the differences between stiff and regular flex golf shafts, factors to consider when choosing the right flex, and tips for testing and selecting the best shaft for your game.

Understanding Golf Shaft Flex

Golf shaft flex refers to the ability of the shaft to bend as force is applied during the swing. The amount of flex impacts how the club feels and performs.


Shaft flex is classified into different categories: extra stiff (X), stiff (S), regular (R), senior (A), and ladies (L). Each category is designed to match different swing speeds and player preferences.

Types of Flex

  • Extra Stiff (X): Minimal bend, suited for very fast swing speeds.
  • Stiff (S): Slightly more bend than extra stiff, for fast swing speeds.
  • Regular (R): Moderate bend, suited for average swing speeds.
  • Senior (A): More bend than regular, for slower swing speeds.
  • Ladies (L): Maximum bend, designed for the slowest swing speeds.

What is Stiff Flex?

Stiff flex shafts are designed for players with faster swing speeds who need less bend in their shafts to maintain control.


  • Less Bend: Stiff shafts have less flexibility, providing a more controlled and accurate shot.
  • Heavier Weight: Often, stiff flex shafts are slightly heavier, adding stability during the swing.


  • Increased Control: Less bend translates to more precise shots.
  • Better Accuracy: Ideal for players who can generate higher swing speeds and need to maintain shot consistency.

Ideal Users

  • Fast Swing Speeds: Typically above 90 mph with a driver.
  • Stronger Players: Those who can handle the extra stiffness and weight.
  • Experienced Golfers: Those with refined swings looking for greater control.

What is Regular Flex?

Regular flex shafts are designed for players with average swing speeds who benefit from more flexibility in their shafts.


  • Moderate Bend: Regular shafts provide a good balance of flexibility and control.
  • Medium Weight: These shafts are generally lighter than stiff flex shafts.


  • Improved Distance: More flex helps in generating higher clubhead speed, translating to longer shots.
  • Better Feel: Suitable for players who need more feedback during their swing.

Ideal Users

  • Average Swing Speeds: Typically between 75-90 mph with a driver.
  • Moderate Strength: Suitable for players with average physical strength.
  • Beginner to Intermediate Golfers: Those still developing their swing mechanics.

Differences Between Stiff and Regular Flex

Understanding the key differences between stiff and regular flex shafts helps in making an informed decision.

Swing Speed

  • Stiff Flex: Best for swing speeds over 90 mph.
  • Regular Flex: Best for swing speeds between 75-90 mph.


  • Stiff Flex: Offers more control for players with faster swings.
  • Regular Flex: Provides more forgiveness and feel for average swing speeds.


  • Stiff Flex: May result in slightly lower distances if the swing speed is not high enough.
  • Regular Flex: Can help achieve greater distances with moderate swing speeds.

Factors to Consider When Choosing Shaft Flex

Several factors should be considered when choosing between stiff and regular flex shafts.

Swing Speed

Your swing speed is the most critical factor in determining the appropriate shaft flex. Faster swings require stiffer shafts, while average speeds benefit from regular flex.


Swing tempo, or the rhythm of your swing, also affects your flex choice. A smooth, consistent tempo might work better with a regular flex, while a quick, aggressive tempo might need a stiff flex.


Physical strength influences your ability to handle different shaft flexes. Stronger players may prefer stiffer shafts for better control.

Experience Level

Beginners often benefit from regular flex shafts due to their forgiving nature, while experienced players might opt for stiffer shafts for precision.

Swing Speed and Shaft Flex

Knowing your swing speed helps in selecting the right shaft flex.

How to Measure Swing Speed

Launch Monitor: Use a launch monitor at a golf store or fitting center.

Swing Speed Radar: Personal swing speed radars are available for home use.

Professional Fitting: A professional fitting session provides accurate swing speed measurements.

Ideal Flex for Different Speeds

  • Below 75 mph: Senior or ladies flex.
  • 75-90 mph: Regular flex.
  • 90-105 mph: Stiff flex.
  • Above 105 mph: Extra stiff flex.

Tempo and Shaft Flex

Matching your swing tempo with the right shaft flex can improve your performance.

Understanding Swing Tempo

Swing tempo is the speed and rhythm of your golf swing. It can be fast, medium, or slow.

Matching Tempo with Flex

  • Fast Tempo: Stiff flex provides better control.
  • Medium Tempo: Regular flex offers a good balance.
  • Slow Tempo: More flexible shafts like senior or ladies flex.

Strength and Shaft Flex

Physical strength plays a role in shaft flex choice.

Role of Physical Strength

Stronger players can handle stiffer shafts, which provide less bend and more control.

Choosing the Right Flex Based on Strength

  • Strong Players: Stiff or extra stiff flex.
  • Moderate Strength: Regular flex.
  • Less Strength: Senior or ladies flex.

Experience Level and Shaft Flex

Your experience level influences the appropriate shaft flex for your game.

Beginners vs. Experienced Players

  • Beginners: Regular flex shafts are more forgiving and easier to control.
  • Experienced Players: Stiff flex shafts offer more precision and control for refined swings.

How Experience Influences Flex Choice

As you gain experience and improve your swing mechanics, you might transition from regular to stiff flex for better performance.

Benefits of Choosing the Right Shaft Flex

Selecting the right shaft flex offers several advantages.

Improved Accuracy

The right flex helps you hit more accurate shots by matching your swing characteristics.

Increased Distance

Choosing the appropriate flex can help you achieve greater distances with your shots.

Better Feel

A shaft that matches your swing speed and tempo provides a better feel and feedback.

Common Mistakes When Choosing Shaft Flex

Avoid these common mistakes when selecting your shaft flex.

Overestimating Swing Speed
