How to measure
- Height: Have your child stand straight against a wall and mark the top of their head. Measure from the floor to the mark.
- Chest: Wrap the tape under their arms and around the fullest part of the chest. Keep the tape level.
- Tip: Measure a shirt they already own and compare it to the chart above for the safest pick.
- Between sizes?: Kids grow fast — size up if they're near the top of a range.
Shorts are sized by waist. Basketball shorts run long and loose; soccer shorts sit higher and shorter. When between sizes, size up for a relaxed feel.

How to measure shorts
- Waist: measure around your natural waistline, just above your belly button. Keep the tape snug but not tight.
- Hips: wrap the tape around the fullest part of your hips and seat. This is the widest point shorts need to clear.
- Inseam: measure from the inside leg seam straight down to where you want the hem to sit. Basketball shorts run longer; soccer shorts are shorter.
- Between sizes? For a relaxed basketball fit, size up. For a closer soccer fit, stay true to size.
Fit by sport
Different leagues cut differently. Here's what to expect before you order.
Soccer jerseys
Standard cut is loose and boxy; tailored cut is slim, stretchy, and shorter. Europeans usually prefer a tighter soccer fit, US fans often size up for a casual look.
NBA jerseys
Standard cut is relaxed and long (drops below the hips). Tailored cut is closer to the body. If you're under 5'10", the body length can feel long — size down for a cleaner fit.
NFL jerseys
Designed boxy with longer sleeves. Most fans buy true to size for a roomy game-day layer. If you want to wear it over a hoodie, size up one.
NHL jerseys
Very boxy because they're designed to fit over hoodies or layers. A Men's Medium NHL jersey often fits like a Large in other sports. Size down if you want a normal silhouette.
MLB jerseys
Button-front, relaxed cut. Similar to a casual baseball shirt. Standard versions run true to size; tailored cuts are slightly trimmer.
NCAA jerseys
Follows the same cuts as US college leagues (football = NFL-like, basketball = NBA-like). Check the league equivalent above for the best guess.

Common questions
Should I size up for jerseys?
Only if you want a loose, streetwear fit or plan to layer over a hoodie. For tailored cuts, many buyers actually size down because the cut is slim.
Are your sizes US, UK, or EU?
We list chest and length in both cm and inches, so you can match by body measurement no matter where you're shopping from.
My chest is between two sizes — which do I pick?
For standard fit, go with the larger size. For athletic fit, check the length too — if you're tall, take the larger size; if you're shorter, the smaller one may fit better.
Can I return a jersey if the size is wrong?
Yes — unworn items with tags attached can be returned within 30 days. See our Return Policy for details.
