To choose the right World Cup jersey size and fit, measure your chest, check the brand’s size chart (adidas, Nike, and Puma each cut differently), and decide between an authentic “player” fit, which is slim and body-hugging, or a replica “stadium” fit, which is relaxed and true to size. When in doubt, the replica fit suits most fans best.

Authentic fit vs replica fit: which should you buy?

The biggest fit decision is not your size, it is the version. Authentic (player-issue) jerseys are cut slim to sit close to an athlete’s body, so they run tight, especially across the chest and arms. Replica (stadium or fan) jerseys use a regular, relaxed cut that is true to everyday sizing and comfortable for normal wear. Most fans should buy the replica version and order their usual size.

How to measure yourself for a jersey

Use a soft tape measure around the fullest part of your chest, under the arms, keeping the tape level. Match that measurement to the chart above, and if you land between two sizes, size up for a relaxed fit or down for a snug, athletic look. If you plan to wear layers underneath in cold weather, size up.

Men’s, women’s, and youth cuts

Most national-team jerseys come in a men’s (unisex) cut by default. Women’s versions are tailored with a shorter, more contoured body, while youth sizes follow age ranges rather than S/M/L. If you are buying for a child, our guide to kids’ jersey sizing breaks down the youth chart in detail.

Common sizing pitfalls

The biggest mistake is buying authentic (player) versions in your usual size, they run a full size smaller than replicas. If you buy an authentic L expecting your normal L fit, it will likely feel tight. Always check whether a kit is authentic or replica before ordering.

Brand differences

Nike, adidas, and Puma each cut slightly differently. Nike tends to run true to size, adidas often runs slim, and Puma varies by model. When in doubt, consult the specific brand’s size chart rather than assuming.

The chest measurement test

Measure around the fullest part of your chest, under the arms, with the tape level. Match the measurement to the chart in centimetres. This is the most reliable way to get the right size, far better than guessing.

Body type considerations

Athletic builds suit true-to-size in both versions. Larger upper bodies should size up in authentic but stay true in replica. Slim builds can size down in replica for a closer look. Choose based on how you want the kit to fit.

Layering and care

If you’ll layer over a long-sleeve top in cold weather, size up. Wash cold, inside out, air dry. Read our full care guide to keep your kit fitting and looking great.

Frequently asked questions

Do World Cup jerseys run big or small?

Replica jerseys run true to size. Authentic player versions run small and slim. If you want a relaxed fit, choose the replica version in your normal size.

Should I size up in a soccer jersey?

Size up if you are between sizes, prefer a loose fit, or plan to layer underneath. Size down only if you want a tight, athletic look.

What is the difference between player and fan jerseys?

Player (authentic) jerseys are slim, lightweight, and pricier. Fan (replica) jerseys are relaxed, durable, and more affordable. Both share the same design.
