          Size & Fit

          The right size, the first time.

          All charts below use international standard body measurements — in inches and centimeters — covering jerseys, shorts, jackets, hoodies and pants across all six leagues.

          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.

          03Quick Size Finder

          Know your chest measurement? Find your size in every league at a glance:

          33–35" 84–89 XS–S S S S S
          35–37" 89–94 S S–M S S–M S
          37–40" 94–102 M M–L M M S–M

          55"+ 140+ 3XL 3XL 4XL 3XL 3XL

          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.

          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.

          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)

          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.

          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 & Baby Sizes

          This is the most complete kids' sizing reference on the page. Our youth sizes run unisex and are consistent across NFL, NBA, MLB, NHL and soccer jerseys, but the label on a listing can vary — Youth S, YthS, “Age 8–10”, a plain number like “10”, or a Boys tag.

          Why do the size brackets look wide? Each kids' jersey is only stocked in a few sizes (S / M / L / XL, or YthXS–YthXL). So one size has to cover several ages — that's the catalog, not a measuring error. The fix is to pick by chest, not by age: measure to the inch and use the ladder below, and you'll land on the right one of the few sizes we carry. When two sizes both fit, take the larger for growth.

          Measure the chest — it's more accurate than age

          • Chest — wrap the tape around the fullest part of the chest, just under the armpits, level. This single number decides the size.
          • Height — barefoot, heels together, head to floor.
          • Weight — a tie-breaker between two sizes.
          • Age — a rough guide only; a tall-for-age child usually needs the size above their age.

          Children's sizes are body measurements, not garment measurements — a Youth M is cut to fit a body of that size, with a little ease. They are not an adult S/M/L shrunk down, so don't guess from an adult size.

          Chest → size ladder (1-inch steps)

          Measure the child's chest in inches and read across. Every band is 1″ wide — as fine as the stocked sizes allow:

          Chest (in) Chest (cm) Recommended size Typical age
          22 56 Boys XS / Toddler 5/6T 4–5
          23 58 Boys XS / 5/6T / YthXS 5

          26 66 Youth S 7–8
          27 69 Youth S 8–9
          28 71 Youth M 9–10
          29 74 Youth M 10–11
          30 76 Youth L 11–12
          31 79 Youth L 12–13
          32 81 Youth XL 13–14
          33 84 Youth XL 14–15
          34 86 Youth XL / Adult XS 15–16
          35 89 Adult XS 16
          36+ 91+ Adult XS / S 16+

          Height → size ladder (2-inch steps)

          If you know the height but not the chest, use this ladder instead — jersey length follows height:

          Height (in) Height (cm) Recommended size Typical age
          33–35 84–89 2T 2
          36–38 91–97 3T 3
          39–41 99–104 4T 4
          42–45 107–114 5/6T / YthXS 5–6
          46–49 117–124 YthXS / Youth S 6–7
          50–53 127–135 Youth S 7–9
          54–56 137–142 Youth M 9–10
          57–59 145–150 Youth M / Youth L 10–12
          60–62 152–157 Youth L 12–13
          63–65 160–165 Youth XL 13–15
          66+ 168+ Adult XS / S 15+

          Height decides the length of the jersey; chest decides the width. If the two ladders disagree (tall and slim, or short and broad), trust the chest ladder for the width and expect a longer or shorter body — or size for chest and accept a little extra length, which reads fine on a casual jersey.

          Fine age chart — half-year steps to age 7, then yearly (ages 2–16)

          The finest reference on this page. Kids grow fastest before 7, so those ages are broken into 6-month bands; from 7 on, one row per year. Find your child's exact age and read across:

          The catalog labels, tightened

          These are the size words that actually appear on listings. We've tightened the age ranges so each band is no more than ~2–3 years:

          One size, many labels

          Don't be thrown by the wording. The catalog writes kids' sizes at least five ways; they overlap. Here's how they map to the ladder above:

          Youth cuts by league — same as adult

          The league silhouette carries down to kids: a youth soccer jersey is still the slimmest, a youth NHL jersey still the roomiest, NFL still boxy. Size by the chest ladder above; only shift if your child is between builds — a slim kid in soccer can take the size down, a broad-chested kid in NHL stays true.

          Buying ahead & layering

          • Size up for growth. If you're between ages or gifting, take the next size. A little room reads as intentional and buys a season of wear.
          • Layer-ready. For winter wear over a hoodie, size up one in NFL/NHL youth; soccer and NBA are fine true-to-size under a light layer.
          • Don't over-size. More than one size up looks sloppy and the sleeves swallow small hands. One size is the safe maximum.

          Kids sizing FAQ

          Why is one size listed for several ages?

          Because each jersey is only stocked in a few sizes (S/M/L/XL or YthXS–YthXL). A single size has to cover the ages in between. That's why we lead with chest measurement — measure to the inch and use the ladder, and you'll pick the right one precisely instead of guessing by age.

          Do youth jerseys fit like the adult ones?

          Yes — same league silhouette, just scaled down. A youth soccer jersey is still the slimmest; a youth NHL jersey still the roomiest. Size by chest using the ladder above.

          What's the difference between YthS and “S (Age 8–10)”?

          Two labels for the same youth small. Some teams use the Yth prefix, others spell out the age. Both fit roughly a 7–9 year old — confirm with the chest column, not the wording.

          My child is 5'6″ — youth or adult?

          Youth XL tops out around 5'6″ (168 cm). At or above that, move to an adult XS or S using the chest chart in Section 01.

          Are toddler and baby sizes true to age?

          They're body measurements, not garment sizes, offered for select teams only. When between two, choose the larger.

          What if the product shows “Size 12” instead of S/M/L?

          That's the numbered kids line: Size 8 = XS, 10 = Small, 12 = Medium, 14 = Large, 16 = XL, 18 = XXL. The printed chest (in inches) is the most reliable number — match it to the ladder above.

          Do you offer youth in Big & Tall?

          Big & Tall (T and B cuts) is an adult range only. For a taller teen, step into an adult XS–S with a Tall (T) cut rather than youth.

          My child is slim / broad for their age — what then?

          Age is a starting point, not a verdict. A slim child can take the size below their age in a fitted cut (soccer, NBA); a broad-chested child should stay true or size up, especially in NFL/NHL. Always confirm with the chest column.

          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

          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

          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

          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)

          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).

          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).

          Measure twice, cheer once.

          Sixty seconds with a tape measure beats two weeks of waiting for an exchange.

          Men's Ty Detmer Royal BYU Cougars Heisman Football Jersey

          Ask most Cougars fans which jersey to buy first and the answer is usually the royal Football one. This is that jersey, in a polyester build made for regular wear.

          Sizing is listed on this page, so the decision does not need a second opinion.

          The Royal BYU Cougars Jersey to Start With

          Polyester Build

          Smooth polyester construction that dries quickly, resists creasing and stays comfortable through a long day of wear.

          Easy to Style

          Works open over a tee, under a jacket, or on its own with jeans. Three outfits from one item.

          Lightweight Comfort

          The polyester build keeps the jersey light on the shoulders, which matters on a warm afternoon in the stands or a long day on campus.

          Comfortable Short Sleeve

          The short sleeve cut keeps the arm free and works under a light jacket when the weather turns on the walk to the ground.

          Why This Is the BYU Cougars Jersey to Start With

          Most people buying their first BYU Cougars jersey want one that fits easily, reads clearly and does not need special care. This royal jersey does all three, which is why it is the version to order rather than deliberate over.

          The royal colourway is the one supporters recognise instantly, the relaxed cut suits more body types than a slim build, and the lightweight polyester fabric works from the tailgate to the drive home. Nothing here needs a second opinion.

          • royal colourway supporters recognise at a glance

          How Supporters Wear It

          Take it to the ground, take it on holiday, or take it to the pub for an away game. It folds small, wears light and keeps the royal reading clearly.

          Fit, Sizing and Ordering Notes

          Size advice: jerseys run a little more generously than t-shirts at the same size. If you are between sizes and want a close fit, take the smaller one; if you want room, take the larger. The size chart on this page lists chest and length.

          Number and name detail: the design carries team graphics in the royal palette. Where a custom build is chosen, the number and name are confirmed at checkout and printed to the football template for this BYU Cougars design.

          Buying Questions, Answered

          How long does it take to arrive?

          Delivery options and the estimated timing are shown at checkout before you pay, so you can see what applies to your address. Nothing about the jersey changes the process - it ships like anything else on the site.

          Is this suitable for kids?

          Youth, kids and toddler sizes are available on many builds in the same royal design, so the whole family can match. Check the size chart by height as well as chest when ordering for a growing child.

          Does it need ironing?

          No. The knit does not crease in normal wear or when folded for travel. If you do iron it, use a low setting and never press directly onto the graphics.

          What size should I order?

          Take the size you normally wear in a t-shirt for a clean fit, or one size up if you want a looser, layered look. The chest measurement is the one that matters most, so compare it against a jersey you already own. A full size chart is on this page.

          Order the BYU Cougars royal jersey and stop comparing. It is the version most Cougars supporters settle on.
