Kids’ Sports Jersey Size Guide

Not sure which size? Compare a T-shirt your child already wears with the measurements below — that's usually all you need.

Size	Approximate Age
XS	4–5 years
S	6–7 years
M	8–9 years
L	10–12 years

Age ranges are estimates only. Children grow at different rates, so always check the garment measurements before choosing a size.

Between sizes? Size up for a looser fit and a little extra growing room.

Fit: Regular fit, standard length, with stretchy fabric for easy movement — perfect for sports, outdoor adventures and everyday play.

Full Garment Measurements

Lay a well-fitting T-shirt or jersey flat and compare its width and length below:

Size	½ Chest (in)	½ Chest (cm)	Length (in)	Length (cm)
XS	12¼	31.1	17	43.2
S	13⅞	35.2	19	48.3
M	15½	39.4	20⅝	52.4
L	17½	44.5	22½	57.2

All measurements refer to the garment, not your child's body. ½ chest is the width across the garment laid flat — double it for the full garment chest circumference.

How to measure a jersey

½ Chest: Lay the jersey flat and smooth out any wrinkles without stretching it. Measure straight across the chest from armpit to armpit.

Length: Measure from the highest point of the shoulder beside the neckline straight down to the bottom hem.

Measurements may vary slightly between garments.
