What is Golf Shaft Flex?
Golf shaft flex simply means how much the shaft bends when you swing the club. The bend is a critical factor in the launching of the ball, the speed, and the direction of the ball. All golfers swing differently; some have a fast and aggressive swing, some a smoother and more in control swing. Due to this, not every shaft works for every golfer.
Here are the common types of shaft flex you’ll find in golf clubs:
- Ladies (L) – best for slow swing speeds, usually under 70 mph.
- Senior (A or M) – good for slightly slower swing speeds (70–80 mph).
- Regular (R) – designed for average golfers with moderate swing speeds (80–95 mph).
- Stiff (S) – ideal for faster swing speeds, usually between 95–105 mph.
- Extra Stiff (X) – used by players with very high swing speeds (105+ mph).
For example, if your swing is at roughly 100 mph, in which case a Stiff shaft flex would give you the best control and distance. When you select an incorrect flex, e.g., Regular rather than a Stiff, the balls will travel too high, get less distance, or they might curve off target. This is why it is critical to learn about such a concept as shaft flex before selecting new clubs.

Why Golf Shaft Flex Matters
Choosing the right shaft flex is not just about comfort; it directly affects your game. The wrong shaft flex can cause:
- Shots that go too high or too low
- Loss of distance
- Hooks or slices due to poor timing
- Inconsistent ball flight
On the other hand, the correct shaft flex helps you:
- Maximize distance by matching energy transfer
- Improve accuracy and control
- Hit straighter, more predictable shots
- Feel more comfortable with your swing
For example, if you swing fast but use a Regular flex, the shaft may bend too much, causing you to lose accuracy. But with a Stiff or Extra Stiff shaft, your swing stays in sync, giving you more power and precision.
That’s why it is important to utilize our Golf Shaft Flex Calculator so you do not waste your money and time on the wrong clubs. Proper shaft flex will make it much easier to get straight distance improvement and consistent results.
Selecting the proper shaft flex can completely turn your golf performance, and our Golf Shaft Flex Calculator can help you with that decision. Instead of guesswork and experimentation, you are provided with a definite recommendation after determining your swing speed, carry distance, tempo, and type of club. Proper shaft flex will give you more distance, straight accuracy, and consistency on the golf course.
