Football Shirt Size Guide: How to Get the Perfect Fit (Nike, Adidas & Puma)

Ordering the wrong size is the most common mistake kit buyers make, and with replica shirts costing £60 or more, it’s an expensive error. This guide walks you through accurate chest measurements, brand-specific size charts for Nike, Adidas and Puma, the key differences between player versions and replicas, and a practical checklist for spotting counterfeits before you pay.

How to Measure Yourself

Grab a soft tape measure and wrap it around the widest part of your chest, just under your armpits and across your shoulder blades. Keep the tape level and don’t pull it tight. If your measurement falls between two sizes, go with the larger option for a more comfortable, relaxed fit.

It’s also worth measuring your waist (around the narrowest part of your torso) if you’re buying a slim-cut or player version shirt. A chest measurement alone won’t tell you how a fitted shirt will sit around your midsection.

Nike Football Shirt Sizes

Nike’s standard replica football shirts fit true to size for most buyers. A Medium corresponds to a 39.5-inch chest. The table below covers their full range.

Important: Nike Elite and Player version shirts are cut significantly slimmer than the chart above. If you’re buying a Nike Player version, size up by at least one full size, and often two if you want any comfort room.

Adidas Football Shirt Sizes

Adidas football shirts run slightly smaller than Nike at equivalent sizes. Their size guide uses chest ranges rather than fixed measurements. If you’re right on the boundary between two sizes, go up.

In practice, someone who wears a Nike Large will often find an Adidas Large is a snug fit. Check your chest measurement against the range rather than assuming your usual letter size carries over between brands. Browse our Adidas replica jerseys and remember to consult this chart before choosing your size.

Puma Football Shirt Sizes

Puma’s football shirts sit roughly in line with Adidas for sizing, though their cuts tend to be slightly boxier at larger sizes. Their range starts at Small rather than XS, so very slim buyers may find the S on the roomy side.

What Is the Difference Between a Player Version and a Replica Football Shirt?

Player versions are engineered for on-pitch performance. They use lighter, stretchier fabric with a slim, aerodynamic cut that reduces drag. Replicas, also called fan versions, use slightly heavier fabric in a relaxed fit built for everyday wear and gifting. The table below summarises the key differences.

If you’re buying a player version to actually wear rather than collect, go up at least one full size. Most buyers find that even two sizes up gives a better result — a player version in your standard size will feel restrictive unless you’re genuinely built like a professional footballer. The Colombia 2026 World Cup goalkeeper jersey is a good example of the slim player-cut silhouette.

How to Spot a Fake Football Shirt

Counterfeit football shirts are more common than many buyers realise. Knowing what to look for before you buy can save you both money and frustration.

1. Check the inner product code label. Every authentic shirt carries a specific product code on the inner label. Search that exact code online — it should match the specific shirt model, colourway and season. Counterfeit shirts often carry incorrect codes or none at all.
2. Look for pen or pencil marks on the label. This is a near-certain sign of a fake. Counterfeiters mark inner labels while counting stock during production. Authentic shirts from legitimate supply chains never carry these marks.
3. Examine the badge and crest. Authentic crests are sharp, centred and cleanly applied. Fakes often show blurry printing, off-brand colours, rough embroidery edges, or a crest that sits slightly off-centre.
4. Feel the fabric quality. Genuine shirts use lightweight technical performance fabric. Counterfeits tend to feel stiffer, heavier, or plasticky. Pay particular attention to the collar and armhole areas, where quality differences are most obvious.
5. Be suspicious of the price and stock availability. Authentic shirts under £40 new are almost certainly counterfeit. Equally, finding a rare vintage or limited shirt in every size from XS to XXL should raise immediate doubts — genuine stock runs out unevenly.

Kids’ and Women’s Sizing: What to Know Before You Order

Kids’ football kits from Nike and Adidas typically run 2–4 years small against the stated age label. A 12-year-old will usually need an age 14 shirt. Always cross-reference the chest measurement on the product page rather than relying on the age guide alone. The Kids Brazil 2026 World Cup kit and the England 2026 World Cup home kit both carry detailed chest measurements in their listings.

Women’s kits by Nike and Adidas are cut narrower through the waist than men’s equivalents. If you prefer a relaxed fit or plan to wear the shirt layered, many women size up within the women’s range or buy from the men’s range instead.

Frequently Asked Questions

Do Nike football shirts run true to size?

Nike standard replica shirts run true to size. However, Nike Elite and Player version shirts are cut slimmer and typically require sizing up by at least one size.

What is the difference between a player version and a replica football shirt?

Player versions use lighter, stretchier fabric with a slim aerodynamic cut designed for on-pitch performance. Replicas use slightly heavier fabric in a relaxed fit suited to everyday wear. Player versions also have heat-transferred badges rather than embroidered ones.

How can I tell if a football shirt is authentic?

Check the inner product code label and search it online. It should match the specific shirt. Authentic shirts have sharp, clean crests, lightweight technical fabric, and are never sold new for under £40.

Should I size up for a player version football shirt?

Yes. Player version shirts run approximately 1–2 sizes smaller than standard replicas due to their slim athletic cut. Most buyers go up at least one full size from their usual size.
