Mini Tennis Guide
Mini tennis (sometimes called "Hot Shots" in Australia) is the internationally recognised system for introducing children to tennis using modified courts, slower balls, and shorter rackets. It's not a dumbed-down version of tennis — it's the smartest way to develop real skills from the start.
What Is Mini Tennis?
The International Tennis Federation (ITF) introduced the "Play + Stay" initiative to solve a simple problem: a full-size tennis court with full-speed balls is too big and too fast for children. Kids were spending more time chasing balls than hitting them, and many quit before they ever experienced what makes tennis fun — rallying.
Mini tennis uses three colour-coded stages (red, orange, green) with progressively larger courts and faster balls. The system is designed so that from their very first lesson, a child can serve, rally, and play points — building confidence and genuine technique from day one.
Tennis Australia's "Hot Shots" programme follows the same ITF framework. Most tennis clubs and coaching programmes in Australia use this system, so the balls your child uses at lessons are the same ones they should practise with at home.
The Three Stages
Stage 1: Red Ball
Ages 4–8 (approx.)
Court Size
11m x 5–6m (roughly the size of a badminton court). Can be set up on any flat surface — driveway, park, school playground.
Ball
75% slower than a standard ball. Larger diameter (8–9cm vs 6.5cm). Low compression foam or felt. Bounces low and slow — easy to track and hit.
Racket Size
19–23 inches. Should be light enough that the child can swing freely without straining their arm or wrist.
Net Height
80cm at the centre (standard tennis net is 91.4cm). A portable net or makeshift barrier works fine for practice.
What kids learn: Basic forehand/backhand grip, tracking the ball, hand-eye coordination, rallying, and scoring. The small court means every shot is within reach.
Stage 2: Orange Ball
Ages 8–10 (approx.)
Court Size
18m x 6.5m (three-quarter length of a full court). Uses the service boxes plus some baseline space. Fits on a standard court with modified lines.
Ball
50% slower than a standard ball. Standard diameter (6.5cm). Slightly heavier compression than red. Bounces higher — introduces topspin and slice.
Racket Size
23–25 inches. More weight than a red-stage racket, building arm strength gradually.
Net Height
80cm at centre (same as red stage). Some programmes use standard height nets at this stage.
What kids learn: Serving (overarm introduced), volleys, movement to the ball, rally construction, and basic match tactics. The bigger court demands better footwork.
Stage 3: Green Ball
Ages 9–12 (approx.)
Court Size
Full court (23.77m x 8.23m singles). Standard dimensions. This is the real thing — just with a slightly easier ball.
Ball
25% slower than a standard ball. Standard diameter and similar feel. Close enough to a real ball that the transition is seamless.
Racket Size
25–26 inches. Some larger juniors move to 27-inch (full-size) rackets at the end of green stage.
Net Height
Standard (91.4cm at centre). Full regulation height prepares kids for the move to regular balls.
What kids learn: Full-court movement, spin variations, tactical serving (placement and power), approach shots, and match-play strategy. Green ball players can compete in junior tournaments.
Stage Comparison Table

|---|---|---|---|
| Age Range | 4–8 | 8–10 | 9–12 |
| Ball Speed | 75% slower | 50% slower | 25% slower |
| Court Length | 11m | 18m | 23.77m (full) |
| Racket Length | 19–23 in | 23–25 in | 25–26 in |

| Scoring | Simplified (first to 7/11) | Tie-break sets | Standard or short sets |
Transitioning Between Stages
The ages above are guidelines, not rules. A child moves to the next stage when they're consistently comfortable at their current level — not when they turn a certain age. Signs your child is ready to move up:
- They're winning most of their rallies easily — the ball isn't challenging them any more
- They're hitting the ball past the baseline regularly — they've outgrown the court size
- Their coach recommends it — coaches who see your child weekly are the best judges
- They're asking for it — motivated kids who want the "harder" ball adapt quickly
What to avoid: rushing the transition. A child struggling on orange balls won't suddenly improve by moving to green. Staying at the appropriate stage builds confidence, which builds enjoyment, which builds retention. The goal is for your child to still be playing tennis at 15 — not to be the youngest kid on a full court at 7.
How Parents Can Help
You don't need to be a tennis player to support your child's development. Here are the practical things that make a real difference:
- Buy the right balls for their stage. Practising at home with regular balls undermines everything they learn in lessons. A 12-pack of stage-appropriate balls costs under $20 and lasts months.
- Hit with them. Stand on the other side of a makeshift net and feed balls gently. You don't need technique — just patience and willingness to collect stray balls.
- Set up a mini court. A portable 3m net and some training cones turns a driveway or park into a practice court in 2 minutes.
- Watch without coaching. At lessons and matches, resist the urge to call out instructions. Encouragement is always welcome; sideline coaching is not.
- Keep it fun. If your child doesn't want to practise, don't force it. The best junior players are the ones who enjoy the sport long enough to develop naturally.
Buying the Right Balls
Stage-specific balls look similar but perform very differently. A red ball dropped from 1 metre bounces about 40cm. A green ball from the same height bounces about 65cm. Using the wrong stage ball is like giving a child a full-size basketball — they can still play, but they'll develop compensating habits instead of proper technique.
