Sizing up your kit is as crucial as picking your favourite player. For fans of the Stars and Stripes, finding the right fit means you can support the team in comfort all year round. Nothing spoils a match day like a shirt that’s too tight or shorts that ride up because you guessed the size.
Wondering which size is best for you? The USA kit size guide is here to help you get it right, whether you’re kitting out yourself, your kids, or shopping as a thoughtful gift. Knowing which measurements matter will give you peace of mind and ensure every cheer feels just right on game day.
How to measure correctly
To find your best fit, always start by measuring your chest with a flexible tape measure. Wrap it under your arms, across the fullest part, keeping the tape flat but not tight. Then, check your height from head to toe with shoes off, standing straight. For little ones, lay them flat and measure from top of the head to heel. Get the chest size right first, then use height as a tiebreaker, especially for fast-growing youngsters. If you sit between sizes or prefer a relaxed feel, move up a size , these supporter kits can come up slim compared to standard sportswear.

Sizing tips for this specific kit brand
USA supporter kits, inspired by the latest Nike design, lean towards a slimmer fit compared to some brands. If you’re between sizes or enjoy a looser style for kickabouts and pub meetups, sizing up is the safer bet. Always check your chest measurement first, as it’s a better guide than just guessing by age or height. For kids, especially those growing quickly, a size larger ensures room to move and extra wear through the season. Babies grow quickly too, so go up a bracket if your little one is near the top of an age or measurement range , softer fabrics make a touch more room feel even more comfortable.
