A football kit should feel like part of your game, not something you keep pulling at between passes. Too tight and it can distract you when you need freedom. Too loose and it may feel heavy, bunch up, or get in the way of a clean first touch. This football kit size guide helps players and parents choose a fit that feels confident from warm-up to the final whistle.
The right size is not about chasing a number on a tag. It is about how the shirt and shorts move with your body, how you like to wear your kit, and whether you are buying for training, match day, or everyday football style. When performance meets faith, you should feel ready to play with purpose.
Start With Measurements, Not Guesswork
Sizes can vary between brands and cuts, so the most reliable starting point is a few simple measurements. A tape measure is best, but a piece of string against a ruler can work if that is what you have at home.
For a football shirt, measure around the fullest part of the chest while keeping the tape level and comfortably relaxed. For shorts, measure around the natural waist, then consider hip and thigh room if you prefer a less restrictive feel. Youth players may also need their height checked, especially when they sit between age-based sizes.
Do not pull the tape tight. A kit is designed for movement, breathing and repeat sprints. The measurement should reflect your normal body shape, not the smallest number you can get.
If you already own a shirt or pair of shorts that fits well, lay it flat and measure across the chest or waist. Double that measurement for a useful comparison with a size chart. This is often easier for parents buying a surprise gift or for players ordering their first kit online.
Measure at the right time
Take measurements over a light T-shirt or close-fitting sportswear, not a bulky hoodie. If you are measuring after a big meal, a gym session, or a long day at school, leave a little room for normal changes in comfort. The goal is a fit you will actually want to wear, not a kit that only works while standing still in front of a mirror.
Football Kit Size Guide: Choose the Fit You Want
Not every player wants the same look. Some love a closer, athletic fit that feels quick and clean. Others want a relaxed silhouette that works for training, travelling, watching matches, and kicking about with mates. Both can be right if the kit still gives you full movement.
A closer fit sits nearer to the chest and shoulders without pulling across the back. It is a strong option for players who want minimal excess fabric and a focused match-day feel. Check that you can lift both arms, twist at the waist and take a deep breath without the shirt riding up or feeling restrictive.
A regular fit has a little more room through the body. It suits most players, especially those wearing a base layer underneath in cooler weather. It is also a practical choice for younger players who are growing quickly or for parents who want a bit more wear from a kit across the season.
An oversized fit is more about off-pitch style than tight match performance. It can look great with track pants, shorts or casual streetwear, but it may not be everyone’s preferred choice for intense sessions. If you want a relaxed look while still training hard, choose enough room to move but avoid a shirt that hangs so low it catches on your shorts.
When you are between two sizes
Being between sizes is common, and there is no single answer. Size down if you like a fitted feel, have a narrower frame, and will mostly wear the shirt on its own. Size up if you prefer a relaxed fit, have broader shoulders, plan to layer underneath, or are buying for a growing young player.
For shorts, comfort around the waist and thighs matters more than how the number looks. A waistband that digs in can become annoying fast during running and shooting drills. If the waist is comfortable but the shorts feel restrictive through the thigh, going up a size is usually the better call.
How a Football Shirt Should Feel in Motion
The best fit test is movement. Put the shirt on and mimic a few football actions: raise your arms for a throw-in, rotate your torso as if striking a ball, bend forward to tie your boots, and jog on the spot. The fabric should move with you rather than fight you.
Look at the shoulders first. Shoulder seams that sit far down the upper arm can signal an oversized fit, while seams pulled high towards the neck may mean the shirt is too small. Across the chest and upper back, the fabric should not stretch tightly or create strong horizontal lines when you move.
Length matters too. A football shirt should generally cover the waistband of your shorts when standing naturally. It does not need to be long and baggy, but it should not expose your midriff every time you reach or sprint. Players with longer torsos may prefer the extra coverage that comes from sizing up, provided the chest still feels comfortable.
Getting Youth Football Kit Sizing Right
For young players, age alone is only a rough guide. Two children of the same age can have completely different heights, builds and growth patterns. Check chest, waist and height wherever possible, then think ahead to how often the kit will be worn.
Buying a kit that is far too big can be tempting, especially when a growth spurt feels close. But oversized sleeves, long hems and loose shorts can make a young player feel less comfortable and less confident. They may also spend more time adjusting their kit than concentrating on the game.
A small amount of growing room is sensible. Aim for a shirt that has comfortable space through the chest and body, while keeping the sleeves and length manageable. If a young player is right at the top end of a size range, moving up may give better value without sacrificing their movement.
Parents and mentors can make sizing a positive part of preparation. Ask the player how they want the kit to feel. A young footballer who feels seen, comfortable and proud in their colours often carries that confidence onto the pitch.
Do Not Forget Shorts, Socks and Layers
A complete kit works as one system. Shorts should sit securely at the waist without needing constant adjustment, and they should allow a full stride, squat and stretch. If the hem pulls across the thighs when you move, the fit is likely too tight.
Socks should feel supportive without cutting into the calf. If shin guards are part of the plan, try the socks with them before match day. Some players prefer a firmer sock for security, while others need extra room through the calf. Comfort is the priority, particularly for junior players who may be less likely to speak up if something is rubbing or pinching.
Think about weather as well. Australian football can mean cool early starts, warm afternoons and changing conditions during the same weekend. If you regularly wear a base layer beneath your shirt, allow for it when deciding between sizes. A close-fit shirt that feels perfect indoors may feel too snug once layers are added.
Check Before You Remove Tags
When your kit arrives, try it on indoors before removing tags or washing it. Wear the type of shorts, socks or base layer you would normally use. Take a few minutes to move properly rather than only checking the mirror.
Ask yourself whether the neckline feels easy, the shoulders can rotate freely, and the waist stays comfortable when you sit down. For a shirt with expressive graphics or faith-centred details, also check that the design sits where you want it to across the chest and body. Fit affects how the whole look comes together.
