Size Guide
NBA Jersey Size Guide: Fit, Measurements & Numbers
NBA · Basketball
Urban basketball, measured right.
Every chart on this page is an NBA chart, built from body measurements in inches and centimetres, men’s and women’s, from small to 3XL. The basketball cut runs standard through the chest with a hem that sits lower than a soccer shirt, so matching your chest once is all it takes.
Know your cut
The basketball cut
Cut: standard, with a longer hem
Sleeveless by design, with a hem that sits lower than most football shirts and a shoulder line that stays close to standard. Nothing to size around — match your chest and you are done.
Basketball sits in the middle of the six leagues we stock: closer to the body than a football or hockey shirt, roomier than a soccer one. The NBA jerseys we carry keep that shoulder line and that longer hem, so the size you already wear is the size to order.

Men’s sizing
Men’s NBA chart
Men's NBA — standard through the chest, hem sits lower than a soccer jersey.
| Size | Chest — in | Chest — cm | Body length — in | Body length — cm | Shoulder — in |
|---|---|---|---|---|---|
| S | 37–39 | 94–99 | 28.5 | 72 | 17 |
| M | 39–41 | 99–104 | 29.5 | 75 | 18 |
| L | 41–43 | 104–109 | 30.5 | 77 | 19 |
| XL | 43–46 | 109–117 | 31.5 | 80 | 20 |
| 2XL | 46–49 | 117–124 | 32.5 | 83 | 21 |
| 3XL | 49–52 | 124–132 | 33.5 | 85 | 22 |
The shoulder column is the fastest way to sanity-check the fit: if your shoulder measurement lands on a row but your chest sits in the row below, trust the chest. Sleeveless shirts show a tight shoulder line immediately.
Women’s sizing
Women’s NBA chart
Women's NBA — sleeveless, contoured, with a shorter hem.
| Size | Chest — in | Chest — cm | Body length — in | Body length — cm |
|---|---|---|---|---|
| S | 33–35 | 84–89 | 26.5 | 67 |
| M | 35–37 | 89–94 | 27 | 69 |
| L | 37–40 | 94–102 | 27.5 | 70 |
| XL | 40–43 | 102–109 | 28 | 71 |
| 2XL | 43–46 | 109–117 | 28.5 | 72 |
For growing fans
Youth NBA chart
Youth sizing, by height
Youth kit is not a shrunken adult shirt — the shoulders and chest come in far narrower, which is why a youth XL is a poor stand-in for a small adult. Youth sizing runs by age band rather than by league, so the scale below is a single youth guide that covers every NBA shirt we carry. Read the height column first, then confirm with the chest.
Youth sizing — body measurements, height first, chest second.
| Size | Height — in | Height — cm | Chest — in | Chest — cm | Waist — in | Waist — cm | Hip — in | Hip — cm |
|---|---|---|---|---|---|---|---|---|
| S | 50–53 | 127–135 | 27 | 69 | 23.5 | 60 | 27.5 | 70 |
| M | 54–60 | 137–152 | 28.5–30 | 72–76 | 25–26 | 64–66 | 29.5–31.5 | 75–80 |
| L | 61–63 | 155–160 | 32 | 81 | 27 | 69 | 33.5 | 85 |
| XL | 65–68 | 165–173 | 35–37 | 89–94 | 29–30 | 74–76 | 37.5–39.5 | 95–100 |
The jersey measured flat
The youth jersey is also measured laid flat rather than worn. The garment range runs in two bands — S/M and L/XL — which is why this second table has two rows against the four above, instead of a line for every letter. Garment figures always read wider than body figures, so do not compare a number across the two tables.
Youth jersey measured flat — garment figures, not body figures.
| Size | Chest — in / cm | Shoulder — in / cm | Length — in / cm | Sleeve — in / cm |
|---|---|---|---|---|
| S/M | 36 / 91 | 17 / 43 | 23.75 / 60 | 18.75 / 48 |
| L/XL | 40 / 102 | 19 / 48 | 26.5 / 67 | 19.75 / 50 |
Between youth and adult
Youth XL tops out at 165–173 cm of height and a 35–37" chest. Past that, a men’s small gives you the extra body and sleeve length a youth XL cannot — see the men’s chart.
Straight answers
Sizing questions
How do I work out my NBA size from scratch?
Measure your chest, then read the row for it in the men’s or women’s chart above. Basketball shirts are sleeveless and cut standard through the chest, so the chest measurement settles the letter on its own — the body-length column tells you where the hem will finish, not which size to take.
My measurement sits between two rows. Which way do I go?
Up. The extra half inch disappears into a relaxed basketball cut, and a longer hem reads as the standard street look rather than a mistake. The one league where you should stay on your true size instead is hockey, where the cut is already very generous.
Are these charts in inches or centimetres?
Both. Every measurement column appears twice, once in inches and once in centimetres, so you can work in whichever unit your tape uses without converting anything in your head. The figures match after rounding to the nearest centimetre.
Men’s or women’s cut?
Women’s jerseys are shaped through the waist and finish higher on the hip; men’s jerseys run straight and boxy. Choosing the men’s cut for the oversized look is a style decision, not a sizing mistake. If you normally wear a women’s size and switch to the men’s chart, go down one size.
