Sizing help
Find your NFL fit.

One league, three charts, zero guesswork. Every number below is a body measurement — inches and centimetres side by side — across men’s, women’s and youth NFL kit. Measure once, read your row, and if you would like a second opinion before your parcel is packed, send us the numbers and we will check them against these charts for you.

Order first, check second. Torn between two rows? Order the size you lean towards, then email your height, chest and waist to fanservice2026@outlook.com. We compare your numbers against these charts before the parcel is packed and swap the size if a different one fits you better. Nothing ships until we agree the size is right.
01

The tape, not the guess

How to measure

Ninety seconds with a soft tape measure settles what no amount of label-squinting will. Wear a single thin layer, stand the way you normally stand, and let the tape touch you without squeezing. No tailor’s tape? Use a piece of string, pinch where it meets, then lay it against a ruler.

Chest — the number that runs the showWrap the tape around the fullest part of your chest, straight under the armpits. Keep it level front to back and breathe normally — do not puff up, do not hollow out.
Waist — your fit-check numberMeasure at the narrowest part of your torso, usually just above the belly button. Tape snug, not cinched. The charts use it to confirm the cut, not to pick the letter.
Body lengthFrom the highest point of the shoulder next to your collar, straight down to where you want the hem to sit. Compare against the length column before committing.
SleeveShoulder seam to wrist bone with your arm slightly bent.
Gap rule: if your measurement lands between two rows, take the larger size. Room reads better than a pull, and the 30-day postage paid return is there if the letter still feels wrong.
02

Right number, right chart

Which number decides

Most sizing mistakes are measurement mismatches — a waist compared against a chest, or a flat-laid garment width read as a body number. This page uses body measurements throughout. Confirm the deciding number here:

Football Sundays

Men’s NFL chart

NFL cuts run full and boxy — the classic oversized game-day shape, made to layer over a hoodie when the temperature drops. Seven sizes, S through 4XL.

NFL jersey — men’s, the full boxy cut, body measurements.

SizeChest (in)Chest (cm)Waist (in)Length (in)Length (cm)Sleeve (in)

Broad through the chest already, or planning to wear it over a hoodie? Order one size up from your row. Otherwise your true size is the right call.

Tapered, not shrunk

Women’s NFL chart

The women’s cut follows the body through the waist and finishes higher on the hip. Six sizes, XS through 2XL.

NFL jersey — women’s, tapered through the waist, body measurements.

SizeChest (in)Chest (cm)Waist (in)Length (in)Length (cm)

XL41–44104–11234–3728.572
2XL44–47112–11937–402974

If the loose, boxy silhouette is what you are after, a men’s small or medium does that job better than sizing up the women’s rows.

The next generation

Youth NFL chart

Youth sizing runs on age bands, confirmed by chest and height. When age and measurements disagree, trust the measurements.

NFL youth jersey — choose by age, confirm with chest and height.

SizeAgesChest (in)Chest (cm)Height (in)Height (cm)
S7–826–2766–6950–54127–137
M9–1228–3071–7655–60140–152
L13–1531–3379–8461–63155–160
XL16–1834–3686–9164–67163–170
Where to look: chest decides an NFL jersey. If your measurement lands in the gap between two rows, take the larger size — a shirt with a little room always looks better than one that pulls.

The questions we get weekly

Sizing questions

Six short answers to the sizing queries that fill our inbox. If yours is not here, email fanservice2026@outlook.com and we will sort it within 48 hours.

Do these charts use body measurements or garment measurements?
Body measurements, throughout — the tape wrapped around you, not the shirt laid on a table. That is why the chest figures read smaller than a flat-laid width.
Which measurement matters most for an NFL jersey?
Chest. Length and sleeve fine-tune the fit, but chest is the number that decides whether the size is right at all.
Do youth sizes follow the same chart as adults?
They do not. The youth chart runs on age bands confirmed by chest and height — see section 05.
I am between two rows. Up or down?
Up. Room reads better than a pull, and the 30-day postage paid return is your safety net if the larger letter still feels off.
Can you check my size before my order ships?
Yes — that is the deal in the box at the top of this page. Email your height, chest and waist with your order number and we will confirm or swap the size before packing.
What if the size that arrives still is not right?
Send it back — 30 days, postage paid, no argument. Start the return by emailing fanservice2026@outlook.com with your order number.

Measure once, cheer all season.

The right size is one email away if the charts leave any doubt.

Youth San Francisco 49ers The Faithful Scarlet Team Game Jersey

YOUR TEAM. YOUR FIT.
A San Francisco 49ers Jersey that earns its place outside the stadium too. Clean lines, a relaxed drape and colors that sit easily next to denim, cargos or a hoodie. Roll the sleeves of an outer layer and let the team graphic sit center frame.

Build & Materials

Wash-tested graphics
Printed and stitched details are checked to stay flat through a normal cold-wash routine.
Two-way stretch
Gives a little in both directions, so it moves with you rather than holding its shape rigidly.
Reinforced neckline
The collar keeps its shape instead of stretching out after a season of wear.

Where It Works

  • Practice, pickup games and playground football.
  • Playing catch in the yard before the game comes on.
  • Gifting to the San Francisco 49ers supporter who already seems to own everything.
  • Airport days and road trips following San Francisco 49ers on the road.

Product Highlights

  • Warm enough for a late-season game with a layer over it
  • Shoulder seams reinforced against stretching
  • Contrast trim that picks up the team colors

Fit, Personalization & Version

Personalization: If you want the classic look, order it plain. If you want it yours, add a name and number and we will build it to the text you supply.
Sizing: Youth sizes follow age-based ranges, so check the chart rather than guessing from height alone.
Version: This is the supporter-grade version - the one you actually wear. It carries the team identity and colors without the collector price tag.

What To Know Before Checkout

Shipping and returns are stated up front. Delivery windows and the return policy are on the site, not buried at checkout.
The jersey you receive matches the page. Edition, color and audience details are the same on the listing and the label.
Listing clarity. Every edition, color and audience is stated up front so there are no surprises.

FAQ

Will the numbers stay on after several washes?
Yes, provided you wash cold and avoid high heat. Heat-sealed and stitched applications are both built for repeat washing.
Is this the same jersey the players wear?
No. This is the supporter-grade version built for everyday wear, not the on-field specification.
Does the jersey have side splits?
Yes. Small splits at the hem keep the fabric from bunching when you sit or lean.
Youth San Francisco 49ers Jersey
Wear the San Francisco 49ers colors with the game look. Add it to the bag and have it ready before the next kickoff.
