Quick answer
Replica shirt? Buy your normal size. Authentic shirt? Size up one.
If you remember nothing else from this page, remember that. Replica shirts (the £75 ones with a loose fit) fit normally. Authentic / player versions (the £110+ ones cut for athletes) fit a full size smaller than every casual T-shirt you already own.
Replica vs Authentic — what's the difference?
Replica (fan)
The £75 option
- • Thicker, more forgiving polyester
- • Loose, comfortable fit
- • Stitched-on badge (most cases)
- • Full range of sizes: XS to 3XL
- • Fits like a normal T-shirt — buy your usual size
Authentic (player)
The £110+ option
- • Lightweight performance fabric (Vaporknit / Heat.rdy)
- • Slim, athletic cut
- • Heat-sealed badge
- • Usually XS to 2XL only
- Size up one — medium players wear large authentic shirts

Women's football shirt sizing
Most 2026 World Cup kits are sold in unisex sizing cut for the average male torso. For women, that usually means sizing down two from your normal UK women's size — so a UK 12 fits a men's XS or S comfortably.
Nike, Adidas and Puma also sell dedicated women's cut shirts for the most popular teams (England, USA, Spain, Brazil, France) — same colours, narrower shoulders, shaped waist, slightly shorter body. The women's cut typically retails at the same price as the unisex replica.
| Women's UK size | Bust | Men's unisex equivalent | Women's cut size |
|---|---|---|---|
| UK 6–8 | 79–84 cm | XS | XS |
| UK 10–12 | 85–92 cm | S | S |
| UK 14–16 | 93–100 cm | M | M |
| UK 18–20 | 101–108 cm | L | L |
| UK 22–24 | 109–116 cm | XL | XL |
Kids football shirt sizing
Kids kits are sold by age range, which roughly corresponds to height. The cut is slim and athletic — kids who are tall for their age should size up. Nike and Adidas age ranges are identical; Puma runs slightly smaller.
| Age | Height | Chest | Brand label |
|---|---|---|---|
| 4–5 yrs | 104–110 cm | 57 cm | XS / 110 |
| 6–7 yrs | 116–122 cm | 60 cm | S / 122 |
| 8–9 yrs | 128–134 cm | 64 cm | M / 134 |
| 10–11 yrs | 140–146 cm | 69 cm | L / 146 |
| 12–13 yrs | 152–158 cm | 74 cm | XL / 158 |
| 14–15 yrs | 164–170 cm | 80 cm | XXL / 170 |

Buying on Amazon — pro tips
- 1. Check the seller. If the seller is “Amazon EU” or the official brand store (Nike, Adidas, Puma), you're getting genuine product with easy returns. Third-party sellers with no reviews are the riskiest.
- 2. Always read the size chart on the listing. Manufacturer charts vary between cycles. The size chart in the listing itself is the authoritative one.
- 3. Check the fit tag. “Regular fit” means replica. “Slim fit”, “Authentic”, “Vaporknit”, “Heat.rdy” or “Player version” all mean authentic — size up.
- 4. Use Prime for free returns. If you're not sure about the size, order two sizes and return one. Amazon Prime members get free returns on most kit purchases.
- 5. Buy early. Popular sizes of the top-selling teams (England, Brazil, Argentina) sell out 4–6 weeks before kick-off. Don't leave it to matchday one.
