How do red, orange and green ball tennis competitions work for my 8U to 10U child (aged 10 and under on 31 December 2026)? Age groups, courts and balls, match formats, grades and Recent Form, line calls, coaching from the sidelines, behaviour, lateness, withdrawing and prizes.
Age groups go by calendar year: your child's age group for the whole of 2026 is set by how old they'll be on 31 December 2026 (Regulation 6 and Appendix Eight, LTA Competition Regulations 2026).
| Year of birth | Own age group in 2026 | Ball | Can also enter |
|---|---|---|---|
| 2018 or later | 8U | Red | 9U only |
| 2017 | 9U | Orange | 10U only |
| 2016 | 10U | Green | 11U only |
| 2015 |
| 12U and older junior age groups |
They're the three stages of tennis for 10 and under, using slower balls and smaller courts. In LTA competitions, 8U plays red, 9U plays orange and 10U plays green. The court and ball specifications come from the ITF Rules of Tennis 2026 (Appendix VIII):
| Stage | Ball | Court | Net height (centre) | Recommended racket |
|---|---|---|---|---|
| Red (up to 8) | Stage 3 red ball | 10.97 to 12.80 m long, 4.27 to 6.10 m wide | 0.800 to 0.838 m | Up to 23 in (58.4 cm) |
| Orange (8 to 10) | Stage 2 orange ball | 17.68 to 18.29 m long, 6.10 to 8.23 m wide | 0.800 to 0.914 m | 23 to 25 in (58.4 to 63.5 cm) |
| Green (advanced 9 to 10) | Stage 1 green ball | Full-size court | Standard | 25 to 26 in (63.5 to 66.0 cm) |
Matches are short. The LTA sets approved and recommended formats by age group (Appendix Seven, LTA Competition Regulations 2026):
| Age group | Approved formats | Recommended format |
|---|---|---|
| 8U (red) | One match tie-break | One match tie-break (all grades) |
| 9U (orange) | One match tie-break; best of three tie-breaks; one FAST4 set | Grades 1-3: best of three tie-breaks. Grades 4-5: one match tie-break |
| 10U (green) | One FAST4 set; best of two FAST4 sets with a match tie-break at one set all | Grades 1-3: best of two FAST4 sets with a match tie-break. Grades 4-5: one FAST4 set |
What the terms mean:
The competition fact sheet states the format before entries open. Under the ITF Rules of Tennis, organisers of 10-and-under events can also set a time limit for matches.
The minimum rest periods between matches that apply to older players (30 or 60 minutes) don't apply to 8U, 9U and 10U events.
Every LTA sanctioned competition is graded (Regulation 5.1, LTA Competition Regulations 2026):
| Grade | Level |
|---|---|
| 1 and 2 | National |
| 3 | Regional |
| 4 | County |
| 5 | Local |
| 6 | Matchplays |
| 7 | Internal venue (club) competitions |
| Ungraded | Recreational competition |
First steps the LTA offers for young players:
Grade 4 and above (County Tour, County Cup, Regional Tour, national events) are aimed at improving and advanced players.
What counts: grades 1 to 5 count towards LTA Ranking (11U and up). Grades 6 and 7 don't count towards Ranking, but from the year your child turns 10, results at any grade from 1 to 7 count towards their World Tennis Number.
Grade 6 and 7 events must use one of the LTA's approved scoring formats for the age group.
Under the LTA Acceptance & Seeding Criteria for mini (ball-colour) events:
| Grade | Who gets in if it's oversubscribed | Seeding |
|---|---|---|
| Grade 5 (local) | First come, first served by date and time of entry; exact ties decided by Recent Form | Recent Form |
| Grades 1 to 4 (county, regional, national) | Recent Form at the closing deadline; ties drawn by lot | Recent Form |
Recent Form is your child's best three individual tournament performances at that ball colour in the last six months.
Tips that follow from the rules:
LTA Membership: yes. Every player in an LTA sanctioned competition must hold LTA Membership (Regulation 15.2), and your child's membership number is needed to enter.
ITF World Tennis Number: issued to players aged 10 or older, or in the calendar year they turn 10 (Regulation 33). Juniors start at 40.9 on a scale from 40 to 1, with separate singles and doubles numbers, and the number comes down as results improve. Results from grade 1 to 7 competitions count towards it.
Rankings and Recent Form:
So a younger child doesn't need a ranking to start. Membership is what they need to enter.
When there's no umpire on court, the players call their own lines (Regulation 29, LTA Competition Regulations 2026):
Wrong calls: if a player calls a ball out and then realises it was good, the point is replayed, unless it was a clear winner, in which case they lose the point. After one wrong call in a match, any further wrong call loses the point.
If your child is unhappy with an opponent's calls or behaviour, they can call the Referee or court supervisor to the court. Parents and other spectators must not get involved or try to influence the decision.
No coaching. Under the Competition Code of Conduct (LTA Competition Regulations 2026), players must not receive coaching during a match, including the warm-up, unless play is suspended and the players have left the court.
"Coaching" is interpreted widely: any communication, audible or visible, between a player and someone off court, including a relative, may be treated as coaching. Signals and gestures count, not just words.
Why it matters for your child: parents count as "Player Support Personnel", and a player is responsible for their support personnel. If you're judged to be coaching, your child can receive a code violation (warning, then point penalty, then game penalty).
Disputes on court: if there's a disagreement over a call, your child should call the Referee or court supervisor. Spectators and parents must not try to resolve the issue or influence any decision.
General conduct: parents and other supporters must behave professionally at the venue and must not attack, disparage or criticise players, organisers, officials or the LTA, including on social media. Breaches can be dealt with under the LTA Disciplinary Code.
The Competition Code of Conduct applies to every player, including 8U to 10U. Code violations include ball abuse, racket abuse, swearing, obscene gestures, verbal or physical abuse, time-wasting, receiving coaching, unsportsmanlike conduct, not trying, and leaving the court without permission.
Penalties during a match (Appendix Five, LTA Competition Regulations 2026):
| Violation | Sanction |
|---|---|
| 1st | Warning |
| 2nd | Point penalty |
| 3rd | Game penalty |
| 4th and later | Game penalty or default |
Minor incidents can be dealt with by a quiet word instead. For something serious (such as hitting someone with a ball or racket, abuse, threats or spitting) the Referee can default the player immediately, from all events at that competition.
Code Violation Points:
Parents' behaviour counts too. Parents are "Player Support Personnel". A player is responsible for their supporters' conduct, so a parent's behaviour can lead to sanctions against the child, as well as action against the parent under the LTA Disciplinary Code.
Under Regulation 21 of the LTA Competition Regulations 2026:
If you arrive ready to play more than 15 minutes after the match was called, the Referee may still agree not to treat it as a withdrawal. They can take into account whether you phoned ahead and how much notice you gave, whether the match can easily be rescheduled, and whether the delay was outside your control. That decision is entirely at the Referee's discretion and can't be appealed.
It depends when you withdraw and the age group (Appendix Six, LTA Competition Regulations 2026).
Before the withdrawal deadline (shown on the competition fact sheet): no penalty.
After the deadline, players get Withdrawal Points, except in 8U events, where no Withdrawal Points are given:
| When | Withdrawal Points |
|---|---|
| After the deadline, up to 2pm the day before the event | 2 |
| After 2pm the day before, or during the event | 4 |
| Not turning up for a match without withdrawing | 6 |
10 points in a rolling 12 months leads to an automatic two-week suspension from LTA competitions (longer for repeat suspensions in the same period).
No points if your child:
Ill before the deadline? Withdraw before the deadline. Points for withdrawing later because of an illness or injury your child already had before the deadline can't be appealed.
Appeals are only for exceptional circumstances outside your control that arose after the deadline, and must be made within 14 days of the LTA's email, with evidence. For a child, the circumstances must have been outside the reasonable control of the parent or carer as well.
Under Regulation 31 of the LTA Competition Regulations 2026:
Separately, the LTA runs LTA Youth Compete Rewards, a participation scheme for 8U to 10U players that recognises their progress through competing.
