Ball speed
In short
Ball speed is the speed of the golf ball immediately after impact. It is measured in km/h or mph and is regarded as the single most important number for how far a shot travels. It depends on club head speed and on strike quality. Launch monitors such as TrackMan show it after every shot.
Ball speed in golf: the meaning explained
After impact the ball leaves the clubface at a certain speed. That speed is the ball speed. TrackMan describes it as the speed of the ball's centre of gravity immediately after separation from the clubface.
It is regarded as the most important factor for distance. A fast ball carries further, a slow ball less, even if the swing looks the same. Ball speed comes from two things. First, club head speed, the speed of the club at impact. Second, strike quality, meaning how centrally and cleanly you hit the ball.
In German you will hear ‘Ballgeschwindigkeit’ or ‘Ball Speed’. On the monitor it is almost always the English term. It always means the speed of the ball after the shot, not of the club.
Units: km/h, mph and m/s
Launch monitors show ball speed in miles per hour (mph) or kilometres per hour (km/h), depending on the setting. One mph is about 1.61 km/h. One metre per second is 3.6 km/h.
Publications from the USA almost always give mph, so a conversion helps. 100 mph is about 161 km/h, 150 mph about 241 km/h. When you compare two values, just make sure you use the same unit.
To calculate smash factor you need ball speed and club head speed in the same unit. This glossary explains smash factor in its own entry. In simple terms: ball speed equals club head speed times smash factor.
Typical values: tour, amateurs and benchmarks
TrackMan publishes averages for the driver. On the PGA Tour ball speed averages about 171 mph, roughly 275 km/h. On the LPGA Tour it is about 143 mph or roughly 230 km/h.
Among male amateurs the values fall with handicap:
- Handicap 0 or better: about 161 mph (roughly 259 km/h)
- Handicap 5: about 147 mph (roughly 237 km/h)
- Handicap 10: about 138 mph (roughly 222 km/h)
- Average golfer, handicap 14.5: about 133 mph (roughly 214 km/h)
- Bogey golfer: about 131 mph (roughly 211 km/h)
For female amateurs the values range from about 131 mph (roughly 211 km/h) at handicap 0 or better to about 111 mph (roughly 179 km/h) at handicap 15. These are driver averages. With irons the values are lower because clubs are shorter and have more loft.
How much distance does more ball speed bring?
According to TrackMan, 1 mph more ball speed can add up to about 2 yards of driver distance, around 1.8 metres. In km/h, each extra km/h is worth a little over a metre, always provided that launch angle and spin are right.
An example: an average golfer reaches 133 mph ball speed with the driver, about 214 km/h. If better strikes lift that to 138 mph, it is 5 mph more. That can mean up to about 10 yards, roughly 9 metres, of extra distance. It is a guide, not a promise. If your strike gets worse in the process, the gain disappears at once.
The gap between groups is striking too. Between a golfer with handicap 0 (161 mph) and the average golfer (133 mph) there are 28 mph. By TrackMan's rule of thumb that is worth up to about 50 metres on a drive.
What determines ball speed
Three factors act most strongly.
- Club head speed: more club speed gives the ball more speed. It grows with mobility, strength and a good sequence of movement.
- Strike location on the face: the sweet spot transfers the most energy. A strike towards the toe or heel costs a lot of ball speed.
- Loft and club type: the less loft, the higher the smash factor. With the driver the upper limit is about 1.50, with wedges clearly lower.
In addition, the equipment rules of the R&A and USGA limit the spring effect of the driver face. That is why smash factor with the driver tops out around 1.5. The ball can also affect the value slightly, for example through hardness and construction. Measurements should therefore always be made with the same ball.
Practical example: more ball speed without swinging faster
A player swings the driver at 150 km/h club head speed. The ball starts at 207 km/h, a smash factor of 1.38. His aim is more distance.
Instead of swinging faster he works on strike location. With foot powder or impact stickers he sees that he often hits the ball near the toe. After two practice sessions he hits the centre more often. At the same swing speed the smash factor rises to 1.45 and the ball now leaves at 218 km/h.
A gain of 11 km/h is about 7 mph. Using TrackMan's rule of thumb that is worth up to about 14 yards, a good 12 metres. The gain comes purely from better strike quality. The example is a simple model. How much you gain depends on your technique and equipment.
Tips and comparison: ball speed, club speed and distance
Ball speed, club head speed and smash factor are often confused.
- Club head speed: the speed of the club before impact.
- Ball speed: the speed of the ball after impact.
- Smash factor: the ratio of the two.
- Carry: the distance to the first bounce, not a speed.
How to improve your ball speed:
- Hit the centre first before you try to swing faster.
- Hit sets at about 80 per cent of your speed and focus only on strike location.
- Judge averages of ten shots rather than single shots.
- Use a club fitting if shaft or loft do not match your speed.
A high number on its own is not enough. Launch angle and spin have to suit the speed, otherwise the gain does not turn into distance.
Try it at Golf Lounge
At the Golf Lounge Resort Hamburg, TrackMan measures ball speed at every hitting mat on the range and in the indoor simulator bays. The simulator offers more than 20 measured values, including club head speed, launch angle, spin and carry. After every shot you can see how much speed arrives in the ball. The simulators can be used all year round whatever the weather. If you would like to review the numbers with a PGA pro, you can book a one-to-one lesson with TrackMan data.
Frequently asked questions
What is ball speed in golf?
Ball speed is the speed of the ball immediately after impact, measured in km/h or mph. It comes from club head speed and strike quality. Launch monitors such as TrackMan show it after every shot, and it is regarded as the single most important number for distance.
What is the average driver ball speed?
According to TrackMan it is about 171 mph (roughly 275 km/h) on the PGA Tour and about 143 mph (roughly 230 km/h) on the LPGA Tour. The average male amateur with a handicap of 14.5 reaches about 133 mph, roughly 214 km/h. With irons the values are lower.
How much distance does more ball speed add?
According to TrackMan, 1 mph more ball speed can add up to about 2 yards of driver distance, around 1.8 metres. That is a guide. It only applies if launch angle and spin suit the higher speed. Gaining speed without a good strike or a matching launch angle brings little in practice.
What is the difference between ball speed and club head speed?
Club head speed is the speed of the club just before impact, ball speed the speed of the ball afterwards. The ratio is called smash factor. With the driver it is about 1.5 at best, so the ball is faster than the club.
How can I increase my ball speed?
Often the biggest gain comes from a centred strike, because it improves smash factor. Beyond that, more club head speed through mobility, strength and a good sequence of movement helps, as does suitable equipment. A PGA professional can use TrackMan data to show where you lose the most speed.
