Search for "best formation for 7-a-side football" and most of what comes back was written for the old age groups, or for adult five-a-side and seven-a-side leagues rather than kids' grassroots football. From the 2026/27 season, the FA's FutureFit changes moved every format up a year, so the formation advice your league used two seasons ago for Under 9s now belongs to Under 10s.
This covers what actually changed, the pitch, ball and substitution rules for both formats, the FA's own suggested formations for each, and how to pick one that fits the squad you've actually got.
Football Formats by Age Group in 2026/27
England Football's FutureFit changes took effect this season, and it's a mandatory change across English grassroots football rather than a trial clubs can opt out of. Every format now starts a year later than it used to:
- Under 7: 3v3
- Under 8 and Under 9: 5v5
- Under 10 and Under 11: 7v7
- Under 12 and Under 13: 9v9
- Under 14 and above: 11v11
If your child is 7 or 8, they're now in 5v5, not 7-a-side. Our drills guide for 7 and 8 year olds covers that age band directly. This article is for the two formats either side of it: 7-a-side from Under 10, and 9-a-side from Under 12.
7-a-Side (7v7): The Format for U10 and U11
England Football's coaching guidance for 7v7 sets out a recommended pitch of 55 x 37 metres (46 x 27m minimum), 12 x 6ft goals and a size 3 ball. Matches run for up to 50 minutes with a match official, rolling substitutions, and deliberate heading not permitted. There's no offside rule at this stage, and it still uses a retreat line and powerplay, both carried over from mini-soccer to help less confident players get on the ball.
England Football suggests two formations for 7v7:
- 2-3-1: two defenders, three midfielders, one striker
- 3-2-1: three defenders, two midfielders, one striker
Both put one outfield player up front and build the rest of the team from there. The choice between them usually comes down to whether you want more width and control in midfield (2-3-1) or more solidity across the back (3-2-1).
When I coached a 7-a-side team, I went with two defenders, three midfielders and a striker, which is one of the two shapes England Football suggests for 7v7. It gave a good balance: one defender could mark the opposition's striker while the other stayed spare, assuming the other team lined up the same way. It also gave me good width from the wide midfielders, and I liked having an attacking player through the middle with the energy to get up and down the pitch.
9-a-Side (9v9): The Format for U12 and U13
England Football's 9v9 guidance covers the step up: a recommended pitch of 73 x 46 metres (64 x 37m minimum), 16 x 7ft goals and a size 4 ball, with matches running for up to 60 minutes. Two things change here that catch out parents used to the old under-11 format: heading is allowed again from this format onward, and offside is introduced for the first time. Rolling substitutions still apply, and England Football's own coaching guidance recommends every player gets at least 50% of the game.
Suggested formations for 9v9:
- 3-3-2: three defenders, three midfielders, two strikers
- 4-3-1: four defenders, three midfielders, one striker
Both add real width and a genuine midfield unit compared to 7-a-side, and with two strikers available for the first time, 3-3-2 gives you a way to play two different types of forward together rather than choosing one.
Choosing the Right Formation for Your Squad
The right formation depends on the players you actually have on a given Saturday, and it's worth revisiting as your squad changes across a season. Three things worth thinking about before settling on one:
- Play to your squad's actual strengths. A formation built around two quick wide players doesn't work if your two fastest children are your central defenders.
- Leave room to develop players outside their favourite position. A good development environment usually involves rotating children through more than one role across a season, rather than locking a talented player into the same position every week because it's convenient.
- Keep it simple in your first season. If you're new to coaching, a straightforward shape the whole team understands is worth more than a more elaborate formation nobody quite remembers under pressure. Our guide to coaching qualifications covers what's actually expected of you at this stage; formation sophistication isn't part of it.
Common Formation Mistakes at This Age
- Copying a formation graphic without adapting it. A shape built around a professional squad's specific players doesn't account for rolling substitutes, mixed ability, or the fact that your "striker" this week might be your best defender next week.
- Treating positions as fixed for the season. Children can start to specialise in one role by Under 12, but Under 10 and Under 11 is still a good age to rotate them through different positions.
- Judging a formation on one result. A shape that concedes three goals against a stronger side isn't necessarily wrong: it's worth watching how it performs across several matches before changing it.
The 2-3-1 shape worked well, but rotating the squad sometimes created its own challenges. I had two strikers: one fast, mobile and a good all-rounder, the other stronger but a bit slower. I enjoyed coaching to their different strengths rather than picking one "right" way to play the position. The bigger, slower striker wasn't as clinical in front of goal, so we worked on his shielding and holding the ball up to bring the midfielders into play.
Formations, Rotation and Fair Playing Time
Both formats run on rolling substitutions. The FA's Standard Code of Rules for Youth Competitions allows a player to come off and go back on more than once during a match, which is what makes the 50% game-time guideline above achievable in practice. A formation that only really works with one specific set of players makes that harder to deliver, since every substitution becomes a small puzzle about who can play where. Our guide to equal playing time in grassroots football covers the maths of fair rotation in more detail.
Building and adjusting a formation for a full squad, while keeping rotation fair across a season, is exactly the kind of admin the Coach App's team selector is built for: drag and drop players into a formation, switch on equal-time rotation, and let it handle the maths you'd otherwise be doing on a notepad at half time.
Frequently Asked Questions
What are the current rules for Under 9 and Under 10 football?
From the 2026/27 season, Under 9s play 5v5, the same format as Under 8s. Under 10s move up to 7v7 alongside Under 11s, using the format and rules covered above. If your child has just turned 9, they're still a year away from 7-a-side.
What if my child's league hasn't moved to the new age bands yet?
The FutureFit changes are mandatory nationally from 2026/27, but individual leagues can take slightly different timelines to fully implement them. If your child's fixtures still look like the old format for their age, check with your league rather than assuming the national timetable, and see England Football's FutureFit pages for the current position.
Do I need to coach the offside rule before a child's first 9-a-side match?
It's worth a short explanation beforehand rather than assuming it'll make sense from watching adult football. Offside is new at 9v9, having not applied at 5v5 or 7v7, so it's often the first time both players and match officials are applying it consistently in a children's match, and a quick, simple explanation before their first game tends to save confusion on the pitch.
Where should less confident players play in a 7-a-side or 9-a-side formation?
Give them a role with clear support nearby for a difficult match, such as alongside a settled midfielder rather than isolated out wide, and treat it as that match's plan rather than a fixed position for the season. Parking a developing player in one "easier" spot every week tends to slow down the rounded development that would actually close the gap with their teammates.
Can you change formation partway through a season?
Yes, and it's normal to. It's worth adjusting as players develop, join or leave the squad, or grow into different positions across a season.
