Jersey Size Guide: NFL, NBA, MLB, NHL, NCAA & Soccer Charts
Every jersey fit, decoded. Measure once, check the chart for your league, and order with confidence — all charts below cover both inches and centimeters, with US–EU conversions included.
How to Measure Yourself
Grab a soft tape measure and wear a thin t-shirt. Two numbers are all you need.
| Measurement | How to take it | Why it matters |
|---|---|---|
| Chest | Wrap the tape under your armpits around the fullest part of your chest. Keep it level, snug but not tight. | The #1 sizing number for every jersey chart on this page. |
| Length | Measure from the highest point of your shoulder straight down to where you want the hem to sit. | Jersey cuts vary by league — hockey and football run long. |
Soccer Jerseys
Soccer fan-edition jerseys use an athletic cut that sits closer to the body. If you prefer the loose terrace look, go one size up.
| Size | Chest (in) | Chest (cm) | Length (in) | Length (cm) |
|---|---|---|---|---|
| S | 35-37.5 in | 89‑95 cm | 27.5 in | 70 cm |
| M | 37.5-41 in | 95‑104 cm | 28.5 in | 72 cm |
| L | 41-44 in | 104‑112 cm | 29.5 in | 75 cm |
| XL | 44-48.5 in | 112‑123 cm | 30.5 in | 77 cm |
| 2XL | 48.5-53.5 in | 123‑136 cm | 31.5 in | 80 cm |
| 3XL | 53.5-58 in | 136‑147 cm | 32.5 in | 83 cm |
NFL Football Jerseys
Football jerseys are cut roomy through the body and sleeves — they're designed to go over a hoodie on cold game days. Most fans take their regular t-shirt size.
| Size | Chest (in) | Chest (cm) | Length (in) | Length (cm) |
|---|---|---|---|---|
| S | 35-37.5 in | 89‑95 cm | 30 in | 76 cm |
| M | 37.5-41 in | 95‑104 cm | 31 in | 79 cm |
| L | 41-44 in | 104‑112 cm | 32 in | 81 cm |
| XL | 44-48.5 in | 112‑123 cm | 33 in | 84 cm |
| 2XL | 48.5-53.5 in | 123‑136 cm | 34 in | 86 cm |
| 3XL | 53.5-58 in | 136‑147 cm | 35 in | 89 cm |
NBA Basketball Jerseys
Basketball jerseys have a longer, straighter hem and a sleeveless cut. Measure a tank top you love and compare the chest width if you're unsure.
| Size | Chest (in) | Chest (cm) | Length (in) | Length (cm) |
|---|---|---|---|---|
| S | 35-37.5 in | 89‑95 cm | 29 in | 74 cm |
| M | 37.5-41 in | 95‑104 cm | 30 in | 76 cm |

| 2XL | 48.5-53.5 in | 123‑136 cm | 33 in | 84 cm |
| 3XL | 53.5-58 in | 136‑147 cm | 34 in | 86 cm |
MLB Baseball Jerseys
Baseball button-ups run true to size with a slightly relaxed body. Between sizes? Size down for a tucked-in look, up for wearing it open over a tee.
| Size | Chest (in) | Chest (cm) | Length (in) | Length (cm) |
|---|---|---|---|---|
| S | 35-37.5 in | 89‑95 cm | 29 in | 74 cm |
| M | 37.5-41 in | 95‑104 cm | 30 in | 76 cm |
| L | 41-44 in | 104‑112 cm | 31 in | 79 cm |
| XL | 44-48.5 in | 112‑123 cm | 32 in | 81 cm |
| 2XL | 48.5-53.5 in | 123‑136 cm | 33 in | 84 cm |
NHL Hockey Jerseys
Hockey jerseys are the roomiest cut in sports — built to fit over pads. They also come in numeric sizes; both charts below say the same thing two ways.
| Size | Chest (in) | Chest (cm) | Length (in) | Length (cm) |
|---|---|---|---|---|
| S | 35-37 in | 89‑94 cm | 30 in | 76 cm |
| M | 37-40 in | 94‑102 cm | 31 in | 79 cm |
| L | 40-44 in | 102‑112 cm | 32 in | 81 cm |
| XL | 44-48 in | 112‑122 cm | 33 in | 84 cm |
| 2XL | 48-52 in | 122‑132 cm | 34 in | 86 cm |
| 3XL | 52-56 in | 132‑142 cm | 35 in | 89 cm |
Numeric size conversion

|---|---|---|

NCAA College Jerseys
College football and basketball jerseys follow a standard athletic cut, true to size for most fans.
| Size | Chest (in) | Chest (cm) | Length (in) | Length (cm) |
|---|---|---|---|---|
| S | 35-37.5 in | 89‑95 cm | 29.5 in | 75 cm |

| 2XL | 48.5-53.5 in | 123‑136 cm | 33.5 in | 85 cm |
Women's Jerseys
Women's cuts are shaped through the waist. If you prefer the oversized boyfriend-jersey look, take a men's size instead — one size down from your usual women's size.
| Size | Chest (in) | Chest (cm) | Length (in) | Length (cm) |
|---|---|---|---|---|
| XS | 29.5-32.5 in | 75‑83 cm | 25 in | 64 cm |

| L | 38.5-41.5 in | 98‑105 cm | 26.5 in | 67 cm |
| XL | 41.5-44.5 in | 105‑113 cm | 27 in | 69 cm |
| 2XL | 44.5-47.5 in | 113‑121 cm | 27.5 in | 70 cm |
Kids Jerseys (6‑12 Years)
Kids' jerseys use the international (EU) height-based numeric standard — the size number simply equals your child's height in centimeters. One row per year of age; chest and height always win over age.
| Size (EU · Age) | Height (in) | Height (cm) | Chest (in) | Chest (cm) |
|---|---|---|---|---|
| 122 · 6‑7 Y | 46-48 in | 117‑122 cm | 24.8 in | 63 cm |
| 128 · 7‑8 Y | 48.5-50.5 in | 123‑128 cm | 25 in | 64 cm |
| 134 · 8‑9 Y | 51-53 in | 129‑134 cm | 26.5 in | 67.5 cm |
| 140 · 9‑10 Y | 53.5-55 in | 135‑140 cm | 28 in | 71 cm |
| 146 · 10‑11 Y | 55.5-57.5 in | 141‑146 cm | 29.5 in | 74.5 cm |
| 152 · 11‑12 Y | 58-60 in | 147‑152 cm | 30.5 in | 78 cm |
Data from official kids' size charts published by major sportswear manufacturers (adidas kids' sizing). Between sizes? Size up — kids grow fast.
Teen Jerseys (12‑16 Years)
The range continues per year with no gap. International youth sizing officially tops out at 176 (15‑16 years) — older or taller teens should move to an adult XS or S from the league charts above.
| Size (EU · Age) | Height (in) | Height (cm) | Chest (in) | Chest (cm) |
|---|---|---|---|---|
| 158 · 12‑13 Y | 60.5-62 in | 153‑158 cm | 32.5 in | 82 cm |
| 164 · 13‑14 Y | 62.5-64.5 in | 159‑164 cm | 34 in | 86 cm |
| 170 · 14‑15 Y | 65-67 in | 165‑170 cm | 35 in | 89 cm |
| 176 · 15‑16 Y | 67.5-69.5 in | 171‑176 cm | 36 in | 91.5 cm |
Official manufacturer kids' size data. 16‑18-year-olds: go by chest — adult XS fits 33‑35 in (84‑89 cm), adult S fits 35‑37.5 in (89‑95 cm).
Toddler Jerseys (2‑5 Years)
Toddler sizes (2T‑5T) pick up right where infant sizes end — the “T” stands for toddler, cut with a little extra room for movement.
| Size | Height (in / cm) | Chest (in / cm) | Weight |
|---|---|---|---|
| 2T 2 yrs | 33-35 in 84‑89 cm | 20-21 in 51‑53 cm | 26‑30 lbs |

| 5T 5 yrs | 41-44 in 104‑112 cm | 23-24 in 58‑61 cm | 39‑45 lbs |
Infant & Baby Jerseys (3‑24 Months)
The tiniest fans are covered too. Infant sizes are sized by month and cut generous for diapers and growth spurts.
| Size | Height (in / cm) | Chest (in / cm) | Weight |
|---|---|---|---|
| 3‑6M 3‑6 mos | 24-27 in 61‑69 cm | 16-17.5 in 41‑44 cm | 12‑17 lbs |
| 6‑12M 6‑12 mos | 27-30 in 69‑76 cm | 17.5-18.5 in 44‑47 cm | 17‑22 lbs |
| 12‑18M 12‑18 mos | 30-32 in 76‑81 cm | 18.5-19.5 in 47‑50 cm | 22‑26 lbs |
| 18‑24M 18‑24 mos | 32-34 in 81‑86 cm | 19.5-20.5 in 50‑52 cm | 26‑30 lbs |
Between months? Size up — babies outgrow jerseys faster than any trophy drought.

Fit Tips & FAQ
Do fan-edition jerseys run big or small?
They run true to standard US sportswear sizing. The charts above reflect the standard industry sizing used across major jersey manufacturers, so your usual t-shirt size is the right starting point — then adjust for the league's cut (roomy for hockey and football, athletic for soccer).
What if my jersey doesn't fit?
No stress. We offer size exchanges — email fkvservice@outlook.com within 30 days of delivery, keep the tags on, and we'll get the right size on its way. Full details are on our Returns & Exchanges page.
Are measurements exact for every product?
Charts show standard body-measurement sizing; individual styles can vary by about ±1 in (2.5 cm) due to fabric and cut. Any product with a notable fit difference says so on its product page.
How do I care for my jersey so it keeps its size?
Cold wash inside-out, hang dry, never tumble dry on high heat. Heat is what shrinks jerseys and cracks heat-pressed names and numbers — treat it right and the fit stays true for years.

About Us
Fan Kits Vault is an independent online retailer of fan edition and replica sports jerseys, founded in 2018 by lifelong supporters and jersey collectors. Today we serve fans in more than 90 countries and regions, shipping from six warehouse and service hubs around the world.
The vault, as we always imagined it — every wall a different game day.
It Started in the Stands
We weren't retailers first. We were the people singing until our voices gave out — the founder and the core crew of Fan Kits Vault are die-hard fans who have spent years following our teams across leagues and continents. And like a lot of supporters, we caught the collecting bug early: a first shirt framed on the bedroom wall, then a shelf, then a closet, then a spreadsheet. (Every collector swears the spreadsheet is just for insurance purposes. It is not.)
Jerseys were never just fabric to us. Each one is a season, a city, a night you'll never forget — the rookie year, the comeback, the final at the last second.
The Problem Every Collector Knows
Here's the honest part: this hobby is expensive. Retail prices kept climbing, and every new season meant choosing between the kit we loved and the budget we had. Passion, it turns out, has a price tag — and it was pricing out the very fans who care the most. We watched friends give up on collecting, or settle for one shirt a year when they wanted five.
At some point, complaining about it over post-match drinks stopped being enough.
So We Built the Shortcut
We spent years doing the unglamorous work: visiting factories, comparing fabrics and stitching side by side, testing wash after wash, walking away from suppliers who didn't meet our standard — and going back to negotiate with the ones who did. Slowly, we built direct channels to quality sources for fan edition and replica jerseys across the sports we love: soccer, American football, basketball, baseball, hockey and college ball.
In 2018, that work became Fan Kits Vault — a discount jersey store built by collectors, for collectors. The idea never changed: the same excitement, the same details, at a price that lets your collection grow faster than one shirt a season.
