New Season, New Numbers: Why Grassroots Football Starts at 3v3 (and What Happens Next)
Football Made Simple for Every Family
A new season, a lot of new questions
If your child is starting football this season, you've probably already noticed something: the game your 6-year-old plays on a Saturday morning looks nothing like the game you watch on TV on a Sunday afternoon. Tiny pitch. Handful of players. A ball that looks almost too small to bother with.
That's not a scaled-down version of "real" football. It's the starting point of a carefully designed journey, one that changes, gradually and deliberately, every couple of years as your child grows. Understanding that journey now will save you a lot of head-scratching later, so let's walk through it.
It all starts with 3v3
At the youngest age group, Under 7s — English grassroots football is now played at 3v3. Three players a side, on a tiny pitch roughly the size of a large living room (about 15–20 yards long), with a small size 3 ball and goals just 4 feet wide.
Games last only 6 to 10 minutes at a time, with no breaks, and a child's total playing time in a single day is capped at 40 minutes for a normal fixture, up to 60 minutes at a festival or tournament. There are no trophies, no leagues and results aren't published anywhere.
To a parent who grew up watching 11-a-side football, that can look almost unrecognisable. But every part of it is intentional.
Why start so small?
Think about what a 6-year-old actually needs from their first taste of football:
Lots of touches on the ball. With only three players a side on a small pitch, nobody is standing around waiting. Everyone is constantly involved.
Simple decisions. A small pitch and small numbers mean less overwhelming choice, easier for a young child to understand what's happening around them.
Short bursts of focus. Young children can't concentrate for long periods, so matches are short and playing time is limited across the day.
No pressure. Without published results or league tables, the focus stays entirely on enjoyment and development rather than winning.
In short: everything is scaled to the child, not the other way around.
The game grows as your child grows
From here, the format changes roughly every one to two age groups, and each change follows the same idea, a slightly bigger pitch, slightly bigger teams, a slightly bigger ball and slightly longer playing time, matched to what children are developmentally ready for.
Here's the general shape of that progression:
Under 7: 3v3, tiny pitch, size 3 ball, 6–10 minute games
Under 8–9: 5v5, bigger pitch, size 3 ball, games played in quarters or halves (10–20 minutes total)
Under 10–11: 7v7, bigger pitch again, size 3 ball, halves up to 25 minutes
Under 12–13: 9v9, a much bigger pitch, size 4 ball, halves up to 30 minutes and this is the point where season-long league tables start to appear
Under 14 and up: 11v11, the full-size game with a size 5 ball, growing pitch and goal sizes and halves up to 45 minutes by the older age groups
Each step isn't arbitrary. It reflects a child's growing physical stamina, spatial awareness and ability to understand teamwork and tactics. A pitch and ball sized for a 7-year-old would be pointless — even unfair — for a 13-year-old, and vice versa.
The bit that catches parents out: more players needed
Here's something that quietly becomes a real challenge for a lot of families and clubs: as the format grows, so does the number of players your child's team actually needs.
A 3v3 team can function with a handful of children. But by the time a team moves to 9v9 or 11v11, clubs need a much bigger squad, enough players to field a full team plus sensible cover for injuries, illness, holidays, and rest. Going from needing 5 or 6 committed children to needing 15 or more isn't a small jump, and it's one of the reasons some smaller clubs merge age groups, share players between teams, or occasionally struggle to field a side during a season.
If you've ever wondered why a coach seems to be constantly recruiting or why your child's team sometimes plays with unfamiliar faces filling in, this is usually why. It's not disorganisation, it's the natural consequence of the format growing up alongside the players.
There's a second, less obvious reason coaches carry larger squads than the pitch strictly needs: players can't be developed overnight. A coach can't simply add five new children to a squad in September and expect them to be ready to contribute in the same way as those who've trained together for a season or two. Every player needs time on the ball, time learning the team's shape, and time building the confidence and understanding that only comes from regular training and match experience. A bigger squad isn't just about having enough bodies for matchday, it's about giving a wider group of children that development time in parallel, so the team has depth that's actually ready when it's needed, not just present.
That's also why game time and rotation can feel like a juggling act as squads grow. With more players to give meaningful minutes to and each of them at a different point in their development, a coach is constantly balancing fairness, learning opportunities and simply picking a team that works on the day. If your child's playing time varies week to week, it's rarely personal, it's usually this balancing act playing out in real time.
Why none of this is published or scored (yet)
One detail that often surprises new parents: for the youngest age groups, right up to Under 11s, results and league tables aren't published, even though matches are still very much played and enjoyed. It's a deliberate choice, designed to keep the early years focused on development, confidence and enjoyment rather than competition and outcome.
That changes from Under 12s onward, when season-long tables start to appear, by which point children are that bit older, more resilient and better equipped to handle the ups and downs of a competitive table.
What this means for you this season
You don't need to memorise pitch sizes or ball dimensions to be a brilliant football parent. But knowing the shape of this journey helps in a few real ways:
You'll understand why your child's game looks different from a friend's older sibling's game — it's not a different sport, just a different stage.
You'll know what's coming next, so the jump to a bigger team or a longer match won't catch you off guard.
You'll understand why clubs sometimes need more volunteers and players as age groups progress and maybe feel ready to help when they ask.
You'll recognise that the lack of scores and tables for younger children isn't an oversight. It's protecting something important: your child's love of the game, before it ever needs to be about winning.
Every stage of this journey exists to meet your child’s needs. As a parent, that's really all you need to know to support them well — the rest, as always, you'll pick up as you go.
Welcome to the season. We are all on the touchline together.
