What Size AFL Guernsey Should You Choose?

A guernsey that is too tight across the chest can make match day uncomfortable. One that is far too loose can feel more like sleepwear than supporter gear. If you are wondering what size AFL guernsey to buy, the best answer is not simply the size you wear in every other shirt. Check the individual product’s size guide, compare it with a garment you already like wearing, and allow for how you plan to wear it.

AFL guernseys are made for supporters of all ages, whether you are heading to the footy, watching from home, buying a birthday gift or adding an officially licensed piece to a growing club collection. Getting the fit right means the guernsey gets worn with pride rather than left in the wardrobe.

What size AFL guernsey is right for you?

Start with the product’s own measurements. This is the most reliable step because sizing can vary between manufacturers, ranges and cuts. A men’s, women’s or youth guernsey may use different dimensions even when the label shows the same size. Retro-inspired styles can also sit differently from a current supporter guernsey.

Your chest measurement is usually the key figure. Using a flexible tape measure, measure around the fullest part of your chest, keeping the tape level and comfortably firm rather than pulled tight. Compare that number with the sizing information supplied for the guernsey you are considering.

If you do not have a tape measure, lay a favourite T-shirt or singlet flat, measure straight across the chest from underarm to underarm, then compare that garment’s fit with the listed measurements. This is especially helpful when buying online, as it gives you a real-world reference point rather than relying on the letter or number on a tag.

When you fall between two sizes, think about fit preference. Choose the smaller option if you like a neater, closer fit and expect to wear the guernsey in warm weather. Go up a size if you prefer room through the body, want to layer a tee underneath, or simply enjoy a relaxed match-day look.

Understand AFL guernsey fits before ordering

Not every AFL guernsey is designed to fit the same way. The term covers several types of supporter apparel, and the intended fit makes a genuine difference to the size that will feel best.

Adult supporter guernseys

Adult guernseys commonly have a straight, relaxed shape that allows easy movement. They are a popular choice for wearing over a T-shirt at the ground, at a barbecue or while kicking the footy with the kids. If that is how you will wear yours, make sure there is enough room across the chest and under the arms without the fabric pulling.

A looser fit is not automatically better. Excess fabric can bunch beneath a hoodie or jacket, and a very long guernsey may feel awkward if you are shorter in the body. Check the garment length where it is provided, particularly if you are buying a larger size for extra width.

Women’s AFL guernseys

Women’s guernseys may be shaped differently through the waist, chest and shoulders. Do not assume a women’s medium will match an adult unisex medium. The product size guide is more useful than converting sizes across ranges.

For supporters who prefer a roomier style, an adult or unisex fit can be a good option, provided the chest and length measurements work. For a closer, more contoured fit, a women’s cut may be the better choice. Neither is more correct - it comes down to comfort and how you want to wear your club colours.

Kids’ and youth guernseys

For children, avoid buying solely according to age. Kids grow at different rates, and an eight-year-old size may be ideal for one child but too snug or too long for another. Measure their chest or compare a well-fitting top with the size guide.

A little extra room is sensible if the guernsey is intended for a full season of footy, but going several sizes up can make it uncomfortable to wear and harder to move in. The shoulder area matters too. If the shoulder seams sit well beyond the child’s shoulders, the guernsey is likely too large right now.

Allow for layers and the way you support

An AFL guernsey is often worn differently depending on the time of year. During an early-season afternoon game, it may be the only top you need. At a cold night match, you might wear it over a long-sleeve tee or under a club hoodie and jacket.

If you are buying a guernsey mainly for summer wear, choose a size that sits comfortably against your body without restriction. If it will be part of your winter match-day kit, allow enough room for a light base layer. You do not usually need to size up for a thin T-shirt, but a heavier long-sleeve top can change the fit across the chest and armholes.

Collectors may take a different approach. If a guernsey is being framed or displayed rather than worn regularly, the exact fit is less important. Even so, selecting the intended adult, youth or infant format helps ensure the piece looks proportionate in a display and is correctly identified as part of your collection.

Do not rely on another brand’s size alone

It is tempting to order the same size as your usual polo, hoodie or NRL jersey. That can be a useful starting point, but it should not be the final decision. Fabric weight, cut and manufacturing specifications all affect how a garment sits.

A cotton T-shirt might stretch and drape differently from a performance-style polyester guernsey. A fitted training top may feel narrower than a classic supporter guernsey with the same chest measurement. Even two AFL products from different seasons can vary slightly.

This is why the size chart on the specific listing matters. Check it each time you buy, particularly when choosing a new style, a retro design or a different range for someone else.

Buying an AFL guernsey as a gift

A guernsey is a memorable gift for a committed supporter, but sizing can feel tricky when you want the surprise to stay a surprise. Start by checking a top they wear often. A quick look at the label may give you a useful guide, while measuring it flat is better again.

Think about their usual style. A supporter who wears oversized hoodies and relaxed tees will probably appreciate more room in a guernsey. Someone who prefers fitted sportswear may be happier with a closer cut. If you are uncertain between two sizes, a relaxed supporter fit generally gives more flexibility than a guernsey that is tight from the first wear.

For children, it can be worth asking a parent or carer for a current clothing size and approximate height. This prevents a well-meant gift arriving after a growth spurt or being too large to enjoy straight away.

Check these details before you commit

Before placing your order, take a moment to confirm the product type, the sizing format and the measurement guide. Look for whether measurements refer to the wearer’s body or the garment itself. If they are garment measurements, compare them with a top you own rather than measuring your body and expecting an exact match.

Also consider whether you are buying an officially licensed AFL guernsey for regular wear, a special occasion, a young fan or a display collection. Your use matters as much as the number on the label. Official supporter merchandise should feel good to wear and look right when you are representing your club.

At Exclusive Collections Australia, the 30-day hassle-free returns policy offers extra reassurance if the fit is not what you expected, provided the item meets the return conditions. It is still worth checking sizing carefully before ordering so your new guernsey is ready for the next siren, family gathering or game-day photo.

The right size is the one that lets you move comfortably, wear your colours confidently and reach for the guernsey every time your club runs out onto the ground.
