# Do You Need a Stiff or Regular Flex Shaft?

By Fayrway Pros · Published 25 September 2026

**The short version**

Shaft flex should match your swing speed. Most club golfers suit regular flex. Choose stiff only if you swing fast (around 95 mph or more of driver speed), and a softer senior or ladies flex if your swing is slower.

- Regular flex suits most amateur golfers
- Stiff for faster, stronger swings
- Wrong flex costs you distance and accuracy

Shaft flex is one of the most misunderstood parts of buying clubs, and getting it wrong quietly costs you distance and accuracy. **The rule is simple: match the flex to your swing speed. Most club golfers suit regular flex, and only fast swingers need stiff.**

### What is shaft flex?

Flex is how much the shaft bends during the swing. A stiffer shaft bends less and needs more speed to load and release properly, while a softer shaft bends more and helps slower swings launch the ball. The flexes, from soft to stiff, are Ladies (L), Senior (A), Regular (R), Stiff (S) and Extra Stiff (X).

### How to choose your flex

Driver swing speed, or how far you carry your driver, is the best guide:

| Driver carry | Rough swing speed | Flex |
| --- | --- | --- |
| Under 200 yards | Under 85 mph | Senior or Regular |
| 200 to 240 yards | 85 to 95 mph | Regular |
| 240 to 260 yards | 95 to 105 mph | Stiff |
| 260 yards plus | 105 mph plus | Stiff or Extra Stiff |

Most amateurs sit comfortably in the regular bracket, which is why regular is the standard choice.

### What happens if the flex is wrong?

- **Too stiff for your swing:** the ball flies low, tends to leak right (for a right-hander), and you lose distance because you cannot load the shaft.
- **Too soft for your swing:** the ball balloons high, can hook left, and feels whippy and inconsistent.

### Should you get fitted?

If you can, yes. A quick fitting measures your actual swing speed and ball flight and removes the guesswork, and it is the single best way to be sure. If you are buying a first set, a forgiving package set in regular flex is a safe starting point.

### Frequently asked questions

#### Do I need a stiff or regular shaft?

Match flex to swing speed. Most club golfers suit regular flex. Choose stiff only if you swing around 95 mph or faster (roughly 240 yards of driver carry), and a softer senior or ladies flex for slower swings.

#### What happens if my shaft is too stiff?

You struggle to load the shaft, so the ball flies low, tends to leak to the right for a right-hander, and you lose distance. If regular feels easier and longer, your stiff shaft is probably too stiff.

#### Is regular or stiff more forgiving?

For most amateurs, regular flex is easier to use and effectively more forgiving, because it helps launch the ball and does not demand high swing speed. Stiff only helps if you genuinely swing fast.

#### How do I know my swing speed?

A launch monitor at a fitting or a golf shop measures it precisely. As a rough guide, your driver carry distance maps to swing speed: around 200 yards is about 85 mph, around 250 yards about 100 mph.
