Is My Child Too Short To Be Good At Tennis?

It’s a question we hear more often than many people realise.

Sometimes it’s asked directly.
More often, it’s asked indirectly.

“My child is one of the smallest in their age group.”
“They’re competing against children who are much bigger.”
“Will they be at a disadvantage if they don’t grow much more?”

For some families, particularly those with ambitious tennis goals, concerns about height can become a source of genuine anxiety. Parents watch tournaments and see taller children serving harder, hitting bigger and often enjoying success against physically smaller opponents. They watch professional tennis and notice that many of the world’s best players are well over 180cm tall.

It’s easy to conclude that height determines success.

Like many assumptions in junior tennis, the reality is more complicated.

Height Matters In Tennis

Let’s start with an honest observation.
Height does matter in tennis.

A taller player generally has a higher contact point on serve. They can create steeper angles, generate more natural power and often cover the court differently. At the professional level, height can provide significant advantages, particularly on faster surfaces where serving becomes increasingly important.

Pretending otherwise doesn’t help anyone.

However, acknowledging that height matters is very different from saying that height determines success.

Those are two completely different conversations.

Junior Tennis Is Full Of Early Developers

One of the most common patterns we see in junior tennis is parents comparing their child to players who are physically more mature.
A twelve-year-old who has already started puberty can look dramatically different from a twelve-year-old who hasn’t.
They may be taller, stronger and faster. They may hit the ball harder and appear more dominant in competition.
The challenge is that physical maturity and future potential are not the same thing.

As we discussed in The Best 10-Year-Old Rarely Becomes The Best 20-Year-Old, many of the strongest junior players are simply early developers. Their physical advantages create immediate success, but those advantages often reduce as their peers catch up.
This doesn’t mean early developers won’t become excellent players. Many do.

It simply means that junior results can be heavily influenced by physical maturity, and parents should be careful about making long-term predictions based on short-term observations.

What Coaches Look At

When coaches evaluate younger players, height is rarely the first thing we’re looking at.
We’re far more interested in questions such as:

How well do they move?
How well do they compete?
Can they solve problems?
Are they coachable?
Do they enjoy the process of improving?

Over the years we’ve worked with plenty of players who were among the smallest in their age group and yet consistently outperformed larger opponents because they developed exceptional movement, consistency, tactical awareness and resilience.

Physical attributes matter.
But they’re only one part of the equation.

The Professional Tour Tells An Interesting Story

Parents are often surprised by the range of physical profiles that exist at the highest levels of tennis.

At first glance, professional tennis can appear to favour height. Many of today’s leading ATP players stand well over 190cm, and there is no doubt that height can provide advantages on serve and when generating power.

However, history shows there is no single physical blueprint for success.

One of the best examples is Diego Schwartzman, who stands just 170cm tall. Despite competing against opponents who were often 20–30cm taller, he reached a career-high ranking of World No. 8 and became one of the most respected competitors on the ATP Tour. He achieved this through exceptional movement, anticipation, consistency and competitive resilience.

Another example is David Ferrer, who stands 175cm tall. Ferrer reached World No. 3, won 27 ATP titles and spent years competing successfully against some of the biggest and most powerful players in the sport. His athleticism, work ethic and ability to absorb pressure became defining features of his game.

On the women’s side, Simona Halep stands 168cm tall. She became World No. 1 and won multiple Grand Slam titles through outstanding movement, court coverage and tactical intelligence rather than overwhelming power.

More recently, Ashleigh Barty, standing 166cm tall, became World No. 1 and won three Grand Slam titles. Barty demonstrated that variety, touch, decision-making and problem-solving can be just as valuable as physical size.

What these players illustrate is not that height is irrelevant. Height clearly provides advantages in certain areas of the game.

What they demonstrate is that elite tennis can be achieved through many different pathways. Some players build their success around power and serving. Others build it around speed, movement, consistency, tactical awareness and resilience.

The challenge for young players is not trying to become taller. The challenge is identifying and developing the strengths they do possess.

The Danger Of Lowering Expectations

One of the biggest risks associated with concerns about height is that adults begin lowering expectations too early.
We’ve occasionally seen situations where parents quietly decide that certain opportunities are unrealistic because their child is smaller than their peers.
The child hasn’t made that decision.
The parent has.

The problem is that nobody knows how a twelve-year-old will look physically at eighteen.
Growth patterns vary enormously.
Some children mature early.
Others mature late.
Some experience significant growth during their teenage years.
Others develop more gradually.

Predicting future physical characteristics from current junior results is often a dangerous exercise.

Height Is Not The Same As Potential

This is particularly important for families who are thinking about performance pathways, college tennis or long-term development.
It’s natural to want certainty. Parents want to understand what opportunities may exist in the future and whether a child is likely to reach a particular level.
Unfortunately, sport doesn’t work that way.
Potential is influenced by many factors:

Technical development
Athleticism
Competitive mindset
Work ethic
Coaching environment
Physical development
Love of the game

Height is simply one piece of a much larger puzzle.

A taller player with poor movement and limited resilience will often struggle. A smaller player with exceptional speed, anticipation and competitive skills can achieve remarkable things.

Focus On What Can Be Controlled

One of the reasons height creates anxiety is that it sits completely outside a player’s control.
No amount of extra practice can change genetics.

What players can control is how they move, how they train, how they compete and how they respond to challenges.
The most successful young players tend to focus their energy in those areas.

They improve their footwork.
They develop better technique.
They learn how to construct points.
They become stronger athletes.

Over time, these improvements often have a far greater impact on performance than parents initially expect.

The College Tennis Question

This concern often becomes more prominent when families start thinking about college tennis or high-performance pathways.
The reality is that college coaches recruit good tennis players.
They are not running height-based selection programmes.
A coach is interested in whether a player can contribute to their team, compete effectively and continue developing.
If a player has built a strong game, demonstrated competitive success and developed a solid UTR, height rarely becomes the deciding factor.

Playing The Long Game

One of the most valuable lessons junior tennis teaches is that development is rarely linear.
The tallest twelve-year-old does not automatically become the best eighteen-year-old.
The strongest fourteen-year-old does not automatically become the strongest adult player.
And the smallest child in a coaching group should never be written off because of their current size.

At The Game, we’ve learnt that the players who ultimately surprise people are often the ones who continue improving while others become distracted by comparisons. Height may influence the style of tennis a player develops, but it rarely determines their commitment, work ethic, coachability or love of the game. Those qualities remain some of the strongest predictors of long-term success, regardless of how tall a player eventually becomes.

Because while height may influence how a player competes, it doesn’t determine how far they can go.
