Take these measurements over a thin t-shirt (never outerwear), standing relaxed with your arms at your sides. Use a soft measuring tape - if you don't have one, wrap a piece of string around the point, mark it, then measure the string against a ruler.

Golden rule: your chest measurement is the number that matters most for jerseys, jackets and hoodies; your waist and hip drive shorts and pants. Match them to the charts below - and if you're between two sizes, always size up.

Not all jerseys are cut the same way. Before you pick a size, know how each league's jersey is designed to fit:

All replica and fan-edition jerseys follow the league's traditional silhouette, matching official retail sizing standards.

Chest measurements are body measurements, not garment measurements. Prefer a looser fit? Choose the larger size whenever you're between two.

NFL replica jerseys are cut full and boxy, the classic sideline look. They're designed to layer over a t-shirt or hoodie.

Men's NFL Jerseys

Order your true size for the classic boxy NFL fit. Already broad-chested or planning to layer over a hoodie? Go one size up.

Women's NFL Jerseys

Women's NFL jerseys have a tapered, contoured cut. If you prefer the classic boxy look, order a men's size S or M instead.

Youth NFL Jerseys

Youth XL fits most teenagers up to about 5'6" (168 cm); after that, move to a men's S.

NBA jerseys are sleeveless with a slightly longer hem, standard through the chest and shoulders.

Men's NBA Jerseys

Women's NBA Jerseys

Youth NBA Jerseys

Youth NBA jerseys follow the same sizing as the general youth chart in Section 9 (S / M / L / XL by age and height).

MLB jerseys are button-front with a relaxed traditional baseball cut - full through the chest and body, hem sits at the hip.

Men's MLB Jerseys

Women's MLB Jerseys

Hockey jerseys are the roomiest cut in sports - wide through the chest and body with extra-long sleeves, designed to be worn over layers. Order your true chest size; do not size up unless you want an extremely oversized fit.

Men's NHL Jerseys

NHL jerseys naturally run 1-2 sizes roomier than soccer or NBA jerseys of the same label. A 40" chest wears an NHL S the way it wears a soccer L.

Soccer jerseys are the slimmest, most tailored cut - designed to sit close to the body like the kits players wear. If you like a relaxed fit or plan to wear a layer underneath, size up one.

Men's Soccer Jerseys

Women's Soccer Jerseys

Youth Soccer Jerseys

Youth soccer jerseys follow the general youth chart in Section 9 . Youth XL transitions naturally into a men's S.

Our youth sizes run unisex and are consistent across NFL, NBA, MLB, NHL and soccer jerseys. When buying for a growing fan, size up - kids always grow into jerseys faster than they wear them out.

Youth Jerseys (Ages 7-18)

Toddler Jerseys (Ages 2-4)

Toddler sizes are only available for select teams. When in doubt between 2T and 3T, choose 3T - toddlers grow fast.

Our basketball, soccer and training shorts follow international athletic-wear standards, sized by waist measurement . Most styles have an elastic waist with drawstring, so each size covers a comfortable range - match your waist and don't overthink it.

Men's Shorts

Length shown is outseam (waistband to hem). Basketball shorts run longer (9-11" inseam); soccer shorts run shorter (5-7" inseam) with a slimmer cut - for soccer shorts, size up if you're between sizes.

Women's Shorts

Women's shorts are cut with a shorter rise and slightly slimmer thigh than men's. Prefer a longer, looser fit? Order a men's small instead.

Youth Shorts

Youth shorts follow the general youth chart in Section 9 - match the child's waist or weight to the same youth S / M / L / XL as jerseys.

Bomber jackets, track jackets, windbreakers and hoodies are cut to international standard outerwear sizing - roomy enough to layer over a jersey or t-shirt. If you plan to wear yours over a hoodie in winter, go one size up.

Men's Jackets & Hoodies

Sleeve is measured from the center back of the collar to the cuff (standard outerwear method), so it runs longer than the shoulder-to-wrist measurement used for jerseys.

Women's Jackets & Hoodies

Cropped jacket styles run 2-3" shorter than shown. Product pages will note when a style is cropped or oversized.

Youth Jackets & Hoodies

Youth jackets and hoodies follow the general youth chart in Section 9 by age and height.

Track pants and joggers are sized by waist with a drawstring closure, so each size adjusts comfortably. Match your waist first; then check inseam for length. Regular inseam fits heights from 5'6" to 6'1" (168-185 cm).

Men's Pants

Taller than 6'1" (185 cm)? Let us know in your order message and we'll prioritize longer-inseam stock for you.

Women's Pants

Women's leggings-style pants run one size snug; track pants follow the chart above.

Youth Pants

Youth track pants and joggers follow the general youth chart in Section 9 by age and height.
