Finding the right West Ham United kit fit is a must for families, friends, and Hammers fans across generations. Whether it’s little ones getting their first kit or parents surprising their teenagers, picking the right size saves hassle and guarantees matchday joy. With so many supporter kit options available for babies, kids, women, and adults, this size guide breaks it down by age group for the smoothest possible shopping experience.
Buying for a baby or toddler
There’s nothing better than welcoming a new member of the West Ham United family with their first kit. Baby and toddler kits are made to be soft and comfortable, so they’re ideal for matchday photos or gentle play. Since babies grow quickly and these kits sometimes run slim, it’s smart to size up if your little Hammer is near the top of an age range.
| Size label | Age | Chest (inches/cm) | Height (inches/cm) |
|---|---|---|---|
| 3-6M | 3–6 months | 17″ / 44cm | 24″ / 62cm |
| 6-9M | 6–9 months | 18″ / 46cm | 26.5″ / 68cm |
| 9-12M | 9–12 months | 18.5″ / 47cm | 29″ / 74cm |
| 12-18M | 12–18 months | 19″ / 48cm | 31.5″ / 80cm |
| 18-24M | 18–24 months | 20″ / 51cm | 33.5″ / 86cm |
| 2-3Y | 2–3 years | 21″ / 53cm | 36″ / 92cm |
For infants, measure around the fullest part of the chest and use height as a secondary guide. If your child is between sizes, always choose the larger for extra comfort.
Junior and youth sizes ages 3 to 13
Kids aged 3 to 13 are especially excited to show their West Ham colours, and these energetic fans need room to move. Junior supporter kits are cut slim compared to everyday t-shirts, so measuring the chest is key before ordering. Go for a size up if your young fan is close to outgrowing their current size, leaving space for growing room over the season.
| Size label | Age guide | Chest (inches/cm) | Height (inches/cm) |
|---|---|---|---|
| XS Kids | 3–4 years | 22″ / 56cm | 39–41″ / 99–104cm |
| S Kids | 5–6 years | 24″ / 61cm | 43–45″ / 109–116cm |
| M Kids | 7–8 years | 26″ / 66cm | 48–50″ / 122–128cm |
| L Kids | 9–10 years | 28″ / 71cm | 53–55″ / 134–140cm |
| XL Kids | 11–12 years | 30″ / 76cm | 57–59″ / 146–152cm |
| XXL Kids | 13 years | 32″ / 81cm | 61″ / 155cm |
Fan versions of West football Ham kits give a slimmer fit than standard loungewear. Sizing up ensures your child stays comfortable during five-a-side kickabouts and stadium celebrations.
Teen to adult crossover
Teenagers on the cusp of outgrowing youth sizes may find themselves between the largest junior and the smallest adult kits. For those aged around 13 and up, especially if they are tall or broad across the chest, try measuring and comparing both the XXL Kids and the S Men’s Adult to see which will give a better, less restrictive fit. Going larger between brackets avoids outgrowing the kit mid-season.
Women’s sizing guide
The women’s supporter kits are styled for a fitted look, following the natural shape of the body while allowing for easy movement. Women’s sizing can feel tighter than unisex t-shirts, so if you prefer a relaxed fit, or find yourself between sizes after taking chest and waist measurements, always pick the larger. West Ham United fan kits for women are a great choice for female supporters joining friends for games, pub meet-ups, or family days at London Stadium.
| Size | Chest (inches/cm) | Waist (inches/cm) | Height (inches/cm) |
|---|---|---|---|
| XS | 31–33″ / 79–84cm | 25–26″ / 63–66cm | 61–63″ / 155–160cm |
| S | 33–35″ / 84–89cm | 27–28″ / 69–71cm | 63–65″ / 160–165cm |
| M | 35–38″ / 89–96cm | 29–31″ / 74–79cm | 65–67″ / 165–170cm |
| L | 38–41″ / 96–104cm | 32–34″ / 81–86cm | 67–69″ / 170–175cm |
| XL | 41–44″ / 104–112cm | 35–38″ / 89–96cm | 69–71″ / 175–180cm |
| XXL | 44–47″ / 112–120cm | 38–41″ / 97–104cm | 71–73″ / 180–185cm |
Men’s adult sizing
Adult men’s West Ham kits follow typical European sizing for supporter kits, but tend to have a slim, athletic cut as preferred by many modern football brands. Always measure around the fullest part of the chest, and size up if you’re between brackets or like a bit of room for layers underneath in winter. Larger sizes keep you comfortable whether you’re in the stadium, at the local, or watching from home with friends.
| Size | Chest (inches) | Chest (cm) |
|---|---|---|
| S | 35–37″ | 89–94 |
| M | 38–40″ | 96–102 |
| L | 41–43″ | 104–109 |
| XL | 44–46″ | 112–117 |
| XXL | 47–49″ | 120–125 |
| 3XL | 50–53″ | 127–135 |
When in doubt or between sizes, always choose the larger option for a relaxed supporter look.
