Jersey Sizing Guide: Men, Women, Youth & Kids
Jersey Sizing Guide: Men, Women, Youth & Kids
Find the right cut across men's, women's, youth, infant, toddler, preschool and unisex. Measure chest and length, and size up for growing kids.
Sizing is where most mistakes happen — fix it before you order
Jerseys run by chest and length, and kids' cuts shrink the window fast.
A jersey that fits right looks twice as good and avoids a return. The single biggest miss is assuming your t-shirt size carries over — jersey blocks are cut for layering, so they often run a touch larger, and youth/infant scales are tighter than adult. The sections below walk the cuts, the measuring method, and the kids-specific gotchas, each linking to the live collection so you can order the right one.
Pick your cut
Seven cuts cover every fan from infant to adult.
- Men's is the traditional male block; women's is tailored narrower through the waist.
- Unisex uses one block for all fans and is the largest single collection.
- Youth, infant, toddler and preschool each have their own size run — do not size down from men's.
How each cut is shaped differently
Seven collections, seven blocks — the label on the tag is not the shape of the jersey.
It helps to know what each cut is designed around before you compare numbers. Men's is the traditional straight block with the longest body and widest shoulders; it is the reference most buyers picture when they think of a jersey. Women's keeps the same team artwork but narrows through the waist and usually shortens the body slightly, so it is not simply men's in a smaller size. Unisex removes the shaping entirely — one straight block meant to tolerate the widest range of body types, which is why it is the safest gift. The four kids cuts are staged by age and proportion rather than by scaling down: youth covers school-age fans, preschool and toddler sit below it with shorter lengths and smaller armholes, and infant is built around onesie-style wear with a more forgiving neckline. Switching cuts changes length, shoulder and armhole at the same time, so always read the chart for the cut in your cart, not the one you measured last.
- A women's cut is shaped, not just smaller — do not convert from men's by dropping a size.
- Unisex tolerates the widest range of shapes; it is the default when the wearer is unknown.
- Kids cuts are staged by proportion, not by dividing an adult size down.
- Team artwork stays the same across cuts; only the block changes.
How to measure
Two numbers decide the fit; write them down before you open the chart.
- Chest: measure across the fullest part, armpit to armpit, and double it.
- Length: measure from the highest shoulder point down to the hem you want.
- Compare both to the size chart for the specific cut — charts are not interchangeable.
- If you are between sizes, size up for a relaxed game-day fit.
Five measurements that decide the fit
Chest and length start the decision; three more explain why a jersey can still look wrong.
Chest and body length are the two numbers on almost every chart, but they do not explain every fit complaint. Shoulder width decides whether the seam lands on the shoulder or slides down the arm; armhole depth decides whether the jersey gaps when you lift your arms; hem width decides whether the bottom sits flat or flares. All three change independently of the chest number, which is why two jerseys with the same chest measurement can wear very differently. Measure each on a garment laid flat, with the tape relaxed rather than pulled tight, and write them down together. If a chart only gives chest and length, use those two and judge the rest from the product photos — the shoulder seam position in a front view is a surprisingly reliable clue.
| Measurement | How to take it | What it controls | Common mistake |
|---|---|---|---|
| Chest width | Armpit to armpit, laid flat, then doubled | Room across the torso and nameplate | Measuring around the body instead of the garment |
| Body length | Highest shoulder point down to hem | Where the hem sits on the hip | Starting the tape at the collar |
| Shoulder width | Seam to seam across the back | Whether the seam drops onto the arm | Ignoring it because the chart omits it |
| Armhole depth | Top of the side seam down to the underarm | Gaping when you raise your arms | Assuming it always scales with chest |
| Hem width | Straight across the bottom edge | Whether the jersey hangs flat or flares | Stretching the fabric while measuring |
- Keep the tape relaxed; pulling it tight quietly adds ease that is not really there.
- Record all five in the same unit before you compare listings.
- If a chart omits a measurement, use the front-view photo to judge seam position.
Read the size chart before the mirror
Body measurements are useful, but a garment you already own is a better reference.
The most reliable way to translate a size chart is to measure a jersey or tee that already fits the way you want, laid flat. Measure straight across the chest from armpit to armpit and double that number for the full chest, then measure from the highest shoulder point down to the hem. Compare those two numbers with the chart for the exact cut you are buying — men's, women's, youth and unisex charts are not interchangeable, and one size label means different things across them. Check whether the chart is in inches or centimeters before you compare, and do not convert in your head. If chest and length land in two different sizes, prioritize chest for a jersey you will layer and length for one you will wear on its own.
- Lay a well-fitting shirt flat and smooth out the fabric.
- Measure armpit to armpit, double it, and record shoulder-to-hem length.
- Note the chart's unit (inches or centimeters) for that specific cut.
- Match chest first, then check length; size up if you plan to layer.
- Measure the garment, not the body — it removes the guesswork about ease.
- A size up from one cut is not the same as a size up from another.
- Write both numbers down before opening a collection; comparing listings gets much faster.
How to read a size chart on a product page
The chart is trustworthy only once you know what its numbers represent.
The first thing to settle is whether the numbers are flat garment measurements or body circumferences — a chest figure can be written either way, and treating one as the other doubles the error. Check the unit next (inches or centimeters) and keep every comparison in that unit. Then look for a tolerance note: measurements are taken by hand from a soft mesh fabric, so a small variance is normal rather than a defect. Do not borrow a chart from another cut, another team or another product line; the same size label is not a shared standard across the catalog. Model photos are styling references, not size evidence — a jersey photographed oversized may simply be the wearer's measured size on a relaxed block. The reliable method is to copy the two or three numbers you need into a note and compare them with the garment you already measured at home.
- Flat garment measurement versus body circumference is the single biggest reading error.
- Keep the unit consistent; do not convert inches to centimeters in your head mid-comparison.
- A hand-measured mesh chart carries a small tolerance — do not treat it as a precision part.
- Use model photos for styling, never for sizing.
Kids sizing in practice
The most common gift mistake, solved.
- Kids grow fast — if the child is mid-range, buy the next size up so the gift lasts the season.
- Infant and toddler cuts are designed for onesies-style wear; check the length especially.
- When unsure of the size, a custom jersey still works as a gift because the sentiment carries.
Once you know the size
Turn the measurement into an order.
With the cut and size confirmed, open Custom to add a name and number in that exact size, or jump to the audience guide to filter by who you are buying for.
Roomy vs snug: pick your fit
Jersey blocks are cut for layering; decide how you want it to sit before sizing.
| Want | Choose | Notes |
|---|---|---|
| Relaxed game-day | Size up | Room for a base layer |
| True to body | Your measured size | Standard jersey block |
| Snug / tuned | Size down | Runs larger than a tee |
| Kids growth | Next size up | Lasts the season |
Between sizes: a decision rule you can reuse
Landing between two sizes is normal — the intended use decides which way to go.
Rather than guessing, run the same short rule every time. If the jersey is for everyday wear with nothing underneath and your chest sits between two sizes, take the smaller one for a cleaner line — provided the length still reaches the hip. If you plan to layer it over a long-sleeve base, take the larger one; the extra room is the point. For a child, take the larger one for growth room, but stop at one size up so the armholes and hem still work. For a gift where the size is uncertain, skip the decision and choose unisex or a custom name-and-number jersey. What you should not do is size up in anticipation of shrinkage: follow the care label, wash cold and hang dry, and treat the chart as the finished dimension rather than a starting point that will change.
- Decide the use first: solo wear, layering, a growing kid, or a gift.
- Compare chest first, then confirm the body length still lands at the hip.
- Solo and between sizes go smaller; layering or a growing kid goes larger, by one size only.
- Unknown wearer goes to unisex or custom — not to a guess.
Do not pre-shrink in your head
Cold wash, inside out, hang dry keeps the fabric stable. Sizing up to allow for shrinkage usually just produces a jersey that is too long on day one.
Wrong size? Returns & exchanges
A miss is fixable — here is the path.
If the jersey does not fit, unwashed and unworn pieces can be returned within 30 days from delivery. Re-measure with the steps above, confirm the cut (men's, women's, youth, etc.), then reorder the right size. For gifts where you are unsure of the size, a custom name-and-number jersey sidesteps the problem because the sentiment carries even if the fit is slightly off.
Fit problems and what actually fixes them
Most wrong-size complaints are a specific, fixable mismatch.
When a jersey feels off, name the symptom before you order a different size — the fix is often a different cut rather than a different number. A hem that hangs past the hip is a length problem; a chest that pulls the nameplate out of shape is a chest problem; shoulder seams sliding onto the upper arm point to a block that is too wide across the back. Gaping armholes on a child are the classic sign of an adult cut sized down instead of an age-appropriate kids cut. Keep unwashed and unworn pieces within the standard 30-day return window so you can exchange, and re-measure the garment that did not work before reordering — that one measurement is worth more than any second guess.
| Symptom | Likely cause | What to change |
|---|---|---|
| Hem hangs past the hip | Body length too long for the frame | Check length; consider a youth or shorter cut |
| Nameplate pulls or bows | Chest too small | Go up one size in the same cut |
| Shoulder seams slide down the arm | Shoulder width too wide | Try a shaped women's cut or a kids cut |
| Armholes gape on a child | Adult block sized down | Switch to the age-appropriate kids cut |
| Rides up when arms are raised | Length too short | Go up one size or choose a longer block |
- Change one variable at a time: size first, then cut — not both at once.
- Measure the jersey that failed before you order its replacement.
Size for what you'll wear under it
Cold-arena and winter wear changes the number you pick.
- Plan to layer? Size up so a long-sleeve base fits under the jersey.
- Summer or indoor wear? Your measured size is correct.
- Kids in winter: next size up leaves room for a thermal base.
Still unsure?
When the size is genuinely unknown — common for gifts — choose unisex or a custom jersey. Both land without an exact measurement.
Youth sizing is not adult sizing scaled down
Kids' jerseys change proportions, not just numbers.
It is tempting to buy the smallest adult size for a child and call it done, but youth, toddler, preschool and infant blocks are proportioned differently: shorter body length, narrower shoulders, smaller armholes and a neckline built for a smaller frame. An adult small on a kid usually hangs long and gaps at the arms even when the chest number looks close. That is why each kids cut has its own size run. For a gift, growth room matters more than a perfect fit on the day — one size up gives the jersey a usable season rather than a few weeks — but avoid going so large that the armholes and hem interfere with movement.
| Adult cut | Youth / kids cut | |
|---|---|---|
| Body length | Longer through the torso | Shorter, scaled to height |
| Shoulders | Wider block | Narrower, smaller armholes |
| Neckline | Adult proportions | Sized for a smaller frame |
| Gift approach | Buy the measured size | Size up for growth room |
Sizing checklist before you check out
Ten seconds of checking saves a return.
- Confirm the cut in the cart matches the wearer: men's, women's, youth, toddler, preschool, infant or unisex.
- Write down chest and length from a garment that already fits the way you want.
- Confirm the chart's unit and whether its numbers are flat garment measurements.
- Check that the chart belongs to this exact cut, not a neighboring one.
- Decide solo wear or layering, and move by one size at most.
- For kids, allow one size of growth room — no more.
- For custom jerseys, re-read the name and number; personalization is not a sizing fix.
- Keep the order confirmation so an exchange inside the 30-day window is straightforward.
When the size is genuinely unknown
Unisex and custom name-and-number jerseys are the two options that do not require an exact measurement. Both are covered in the audience and custom guides.
