How to get your measurements right
Measuring up correctly at home takes only a minute but saves a world of faff with returns. Start with your chest: run a measuring tape under your arms around the fullest part. Keep it snug, but not tight. Next, check your height standing straight, heels together, for those in-between scenarios where you’re close to a size cut-off.
For kids and babies, chest measurement is your main guide. If your child is nearly at the top of their age bracket or is growing rapidly, do them a favour and size up. For all ages, bigger is usually better for comfort, layering during those chilly away days, and letting little ones enjoy their kit for as many matches as possible.
Sizing tips specific to Belgium supporter kits
Belgium fan kits, like many high street supporter shirts, tend to follow current Nike and Adidas trends toward a slimmer, more athletic cut compared to baggier sportswear of years gone by. Adults, especially those preferring a looser fit or planning to wear the kit over a t-shirt, should choose one size larger than their everyday top. Women’s fits mirror this with a tapered shape at the waist, so sizing up brings a relaxed, comfy feel.
For junior and infant Belgium kits, softer fabrics are the norm, but growth spurts catch up fast, so always check those chest and height guides together. Anyone on the cusp between sizes is always better off choosing the next size up, particularly if gifting or buying before a tournament,nobody wants a tight shirt before a big match!
Home vs away , does sizing differ?
Belgium home and away kits are made to the same cut and feel, regardless of colour or design details for each season. Whether you’re backing the team in iconic red or the latest away pattern, sizing will be consistent across both versions. Fan kits for major tournaments and regular seasons follow these same measurements.
Keep in mind, if a limited-edition kit is released around the 2026 World Cup, sizing will likely stick to the same measurements as above. Always check this Belgium kit size guide before ordering to stay confident you’re buying what fits your matchday plans.
