Not sure which size to pick? No problem — just place your order with the size you think fits best. Then send us your height, chest and waist measurements (plus hip for shorts and pants) via the order message or email to fanservice2026@outlook.com, and our team will double-check your size before shipping. If a different size fits you better, we'll send that one instead — you get the size that actually fits, not the one you guessed.

01How to Measure

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.

1. Chest — most important

Measure around the fullest part of your chest, directly under the armpits. Keep the tape parallel to the floor and don't puff your chest out.

2. Waist

Measure around your natural waistline — the narrowest part of your torso, usually just above the belly button.

3. Hip — for shorts & pants

Measure around the fullest part of your hips and seat, with your feet together. This is the key number for bottoms.

4. Body Length

Measure from the highest point of your shoulder (next to the collar) straight down to where you want the hem to sit.

5. Sleeve

For long-sleeve jerseys and jackets (NFL, MLB, NHL): measure from the shoulder seam down to your wrist with your arm slightly bent.

6. Inseam — for pants

Measure from your crotch straight down to your ankle bone along the inside of your leg. This determines pant length.

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.

02Fit by League

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

League	Fit Type	How It Should Feel
Soccer	Athletic / slim	Close to the body; size up for a looser look
NBA	Standard / slightly long	Relaxed through the chest, longer hem
NFL	Roomy / boxy	Classic oversized game-day look
MLB	Full / button-front	Relaxed traditional baseball cut
NHL	Very loose	The loosest cut of all leagues — order your true size, no need to size up

All replica and fan-edition jerseys follow the league's traditional silhouette and match standard retail sizing.

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

04NFL Football Jerseys

Roomy / boxy fit

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

2XL	44–47	112–119	37–40	29	74

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.

XL	16–18	34–36	86–91	64–67	163–170

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

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

05NBA Basketball Jerseys

Standard / long fit

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

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).

06MLB Baseball Jerseys

Full / button-front fit

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

Size	Chest (in)	Chest (cm)	Length (in)	Length (cm)	Sleeve (in)

2XL	43–46	109–117	28.5	72

07NHL Hockey Jerseys

Very loose fit

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

Size	Chest (in)	Chest (cm)	Length (in)	Length (cm)	Sleeve (in)
S	40–43	102–109	30	76	24

2XL	52–55	132–140	34	86	28
3XL	55–58	140–147	35	89	29

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.

08Soccer Jerseys

Athletic / slim fit

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

Youth Soccer Jerseys

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

09Youth & Toddler Sizes

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)

Size	Ages	Chest (in)	Chest (cm)	Height (in)	Height (cm)	Weight (lb)
S	7–8	26–27	66–69	50–54	127–137	55–70
M	9–12	28–30	71–76	55–60	140–152	75–95
L	13–15	31–33	79–84	61–63	155–160	100–120
XL	16–18	34–36	86–91	64–67	163–170	125–145

Toddler Jerseys (Ages 2–4)

Size	Ages	Height (in)	Height (cm)	Chest (in)	Chest (cm)	Weight (lb)
2T	2	33–35.5	84–90	21	53	26–29
3T	3	36–38.5	92–97	22	56	30–34
4T	4	39–41	99–104	23	58	35–39

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

10Shorts

Elastic waist / drawstring

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

Size	Waist (in)	Waist (cm)	Hip (in)	Hip (cm)	Shorts Length (in)	Length (cm)
S	29–32	74–81	35–37.5	89–95	18–19	46–48
M	32–35	81–89	37.5–41	95–104	19–20	48–51
L	35–38	89–97	41–44	104–112	20–21	51–53
XL	38–43	97–109	44–48	112–122	21–22	53–56
2XL	43–47	109–119	48–52	122–132	22–23	56–58
3XL	47–52	119–132	52–56	132–142	23–24	58–61

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

Size	Waist (in)	Waist (cm)	Hip (in)	Hip (cm)	US Size
XS	24–25	61–64	33–34.5	84–88	2–4
S	25–27	64–69	34.5–36.5	88–93	4–6
M	27–30	69–76	36.5–39	93–99	8–10

XL	33–37	84–94	41.5–44.5	105–113	16–18
2XL	37–41	94–104	44.5–47.5	113–121	20–22

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.

11Jackets & Hoodies

Layer-friendly fit

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

Size	Chest (in)	Chest (cm)	Waist (in)	Length (in)	Length (cm)	Sleeve (in)
S	35–38	89–97	29–32	26–27	66–69	33.5
M	38–41	97–104	32–35	27–28	69–71	34.5
L	41–44	104–112	35–38	28–29	71–74	35.5
XL	44–48	112–122	38–43	29–30	74–76	36.5
2XL	48–53	122–135	43–48	30–31	76–79	37.5
3XL	53–58	135–147	48–53	31–32	79–81	38.5

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

Size	Chest (in)	Chest (cm)	Waist (in)	Length (in)	Length (cm)
XS	31–33	79–84	25–26	23–24	58–61

2XL	44–47	112–119	37–40	28–29	71–74

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.

12Pants, Joggers & Track Pants

Drawstring waist

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

14Sizing FAQ

Do your jerseys run big or small?

Each league follows its traditional cut: soccer is slim, NBA is standard, NFL and MLB are roomy, NHL is the loosest. Match your chest measurement to the chart for your league and you'll get the intended fit. If you're ordering across leagues for the first time, check the Quick Size Finder in Section 3 — the same body often wears a different size in different leagues.

I'm between two sizes — which should I pick?

Size up. Jerseys are casual wear designed to be worn relaxed; a half-size of extra room always looks better than a snug fit. The only exception is NHL hockey jerseys — they already run very loose, so stay at your true size.

Should I buy men's or women's jerseys?

Women's jerseys have a tapered, contoured cut through the waist; men's jerseys are cut straight and boxy. Many fans prefer the men's fit for the classic oversized look — that's a style choice, not a sizing error. Women ordering a men's cut should typically go one size down from their women's size.

Youth XL or men's S — which one for a teenager?

Youth XL fits up to about 5'6" (168 cm) and a 34–36" chest. Above that, move to a men's S — it's cut longer in the body and sleeves.

Do I wear the same size in jerseys, shorts and jackets?

Usually close, but not always. Jerseys and jackets are sized by chest; shorts and pants are sized by waist and hip — many fans wear a jersey L but a shorts M. Always check the chart for the product type you're ordering rather than reusing your jersey size across categories.

What if the size still isn't right?

No problem. Every order is covered by our 30-Day Returns policy — swap for a different size and we'll make it right. Questions before you order? Email fanservice2026@outlook.com with your chest measurement and the item you're eyeing, and our team will recommend a size within 24–48 hours. Or simply place your order and send us your height, chest and waist measurements in the order message — we'll verify your size before shipping (see the note at the top of this page).

04What the Game spec means

The Game build is the supporter-grade version of the New Orleans Saints shirt: the same matchday look, cut for everyday wear rather than on-pitch use.

05How to Pick Your New Orleans Saints Jersey Size

1Lay a jersey that fits you flat

Use a New Orleans Saints shirt you already wear, or any youth top that sits right on the shoulders.

2Measure chest and length

Measure across the chest and from shoulder to hem, then match both numbers to the size chart on this page.

3Decide your layering
