If you're a coach, committee member or parent connected to grassroots football this season, you'll have heard the term FutureFit doing the rounds. It's the FA's biggest shake-up of youth football formats in years, and clubs across the country are rolling it out for 2026/27. It's not just a tweak to the fixture list — it changes squad sizes, pitch dimensions, and even the equipment kids need. So we've put together a practical guide to what's changing and how to make sure your kit bag (or your club's stock cupboard) is ready for it.
What's changing, and why
FutureFit is the result of the FA working with Liverpool John Moores University, studying more than 400 grassroots matches to see how kids actually experience the game. The findings won't surprise anyone who's stood on a touchline watching a crowded 11v11 U8 match: too many players chasing one ball means fewer touches, less involvement, and less development for the majority of the squad.
The new framework is designed to fix that, with smaller-sided formats at every age group up to U13, alongside extended heading restrictions. Previously capped at U7-U10, heading guidance now applies right up to U11, reflecting the same evidence-led approach to managing physical impact in the modern game.
3v3, 5v5, 7v7, 9v9 explained: youth football formats by age group
Here's how the new structure breaks down nationally from this season:
- U7 – 3v3, no goalkeeper, no referee, no mid-game substitutions, played on a small pitch of roughly 10m x 15m
- U8-U9 – 5v5, first introduction to a goalkeeper
- U10-U11 – 7v7
- U12-U13 – 9v9
- U14 and above – 11v11, unchanged
The logic is simple: smaller formats mean more touches of the ball, more decisions per player, and more space to actually develop skills — rather than eleven kids and one ball on a full-size pitch.
Football ball sizes by age (UK): getting it right
One of the most common kit mix-ups at grassroots level is using the wrong ball size for the age group — it sounds minor, but it affects everything from first touch to shooting technique. Under FutureFit, ball size is tied to format rather than to age alone, so it stays the same right across the foundation-phase formats before stepping up:
- U7-U11 – Size 3
- U12-U13 – Size 4
- U14 and above – Size 5
A good all-rounder like the Optimum Classico Football (Sizes 3, 4 & 5) covers every age band, so it's worth checking your club's ball bag against the sizes above before the season kicks off properly. If you're a committee member sorting balls for multiple age groups at once, buying in a Classico Football Bulk Pack of 10 or 25 is usually the most cost-effective way to get every team sorted in one order.
Goalkeeper kit: when do you actually need it?
Under the new format, U7 football is played without a goalkeeper at all — so there's genuinely no need to kit out a keeper for your youngest players this season. That changes as soon as squads move up to 5v5 at U8-U9, when a goalkeeper is introduced for the first time. That's usually the point where a first pair of proper gloves makes sense — something like the Optimum Mosquito MX PRO Goalkeeper Gloves gives young keepers grip and confidence without overcomplicating things for a first-timer in goal.
Junior football boots: a guide as kids progress
Footwear is one area where it really does pay to buy for the stage a child is at, not just their shoe size. Younger players at U7-U9 tend to get on best with easy-fasten styles that they can manage themselves before training — the Optimum Razor Junior Easy Fasten Boots are a solid option here.
As players move into the 7v7 age groups and start playing on bigger pitches with more running, a traditional lace-up boot like the Optimum Ignisio Junior Lace-Up Boot offers a more secure, locked-in fit. By the time kids reach 9v9 and 11v11, with more twisting, turning and grass-pitch play, a boot built for durability and support — such as the Optimum Junior Razor 6 Stud Football Boots — is worth the step up. If you're not sure which stage your player is at, the full junior boot range is a good place to compare options side by side.
Shin pads: still non-negotiable
Whatever the format — 3v3 right through to 11v11 — shin pads remain mandatory. It's an easy one to overlook when everything else about the season is changing, but it's worth checking every player's pads still fit properly, especially after a growth spurt over the summer. A lightweight, comfortable option like the Optimum Velocidade Ankle Sock Shin Guards is a straightforward way to tick that box for the whole squad.
Training kit for smaller squads and groups
One knock-on effect of FutureFit that's easy to miss until you're actually on the training pitch: smaller match-day formats mean many clubs are now splitting bigger squads into smaller practice groups to mirror the 3v3/5v5/7v7 structure in training. That's brilliant for development, but it does mean more grids, more mini-games running side by side, and more distinct teams to mark out — which usually means more kit is needed, not less.
A decent supply of Training Bibs makes it far easier to run three or four small-sided games at once without confusion over who's on which team, and a set of Collapsible Training Marker Cones (Set of 4) is invaluable for quickly marking out multiple smaller pitches and grids across one session.
Kit checklist by age group
To pull it all together, here's a quick kit list for youth football teams under the new structure:
- U7 (3v3) – Size 3 ball, shin pads, easy-fasten boots, no goalkeeper kit required
- U8-U9 (5v5) – Size 3 ball, shin pads, boots, first goalkeeper gloves for the squad's keeper
- U10-U11 (7v7) – Size 3 ball, shin pads, lace-up boots, goalkeeper gloves
- U12-U13 (9v9) – Size 4 ball, shin pads, supportive boots, goalkeeper gloves
- U14+ (11v11) – Size 5 ball, shin pads, match-ready boots, full goalkeeper kit
Ready for the new season
FutureFit is a genuinely positive change for grassroots football — more touches, more involvement, and a format built around how kids actually develop. Getting the kit right alongside it doesn't need to be complicated: right-sized balls, shin pads for everyone, boots that match the pitch and stage your players are at, and enough bibs and cones to run smaller training groups smoothly.
Once you've sorted the essentials, a Sport Player Kit Bag or Boot Bag makes carrying it all to training and matches a lot easier — for players and parents alike. And if you want to browse everything in one place ahead of the season, our full Sports - Football collection has you covered.
