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 league chart below.
Length	Measure from the highest point of your shoulder straight down to where you want the hem to sit.	League cuts vary — hockey and football run longest.

NFL Jersey Sizing — Football Jerseys

NFL fan version jerseys are cut roomy for layering over hoodies on cold gamedays. The shoulders are generous, the sleeves hit mid-bicep, and the body is boxy by design — that is how football jerseys are meant to be worn.

Size	Chest (in)	Chest (cm)	Length (in)	Length (cm)
XS	32-35	81-89	27	69
S	35-37.5	89-95	28	71
M	37.5-41	95-104	29	74
L	41-44	104-112	30	76
XL	44-48.5	112-123	31	79
XXL	48.5-53.5	123-136	32	81
3XL	53.5-58	136-147	33	84
4XL	58-63	147-160	34	86
5XL	63-68	160-173	35	89

How it fits: True to size for most fans. Size up one if you plan to layer a hoodie underneath.

NBA Jersey Sizing — Basketball Jerseys

NBA fan version jerseys are sleeveless with a longer, straight body — the classic on-court cut. Armholes are cut deep so the jersey moves with you, whether you wear it solo in summer or over a t-shirt.

Size	Chest (in)	Chest (cm)	Length (in)	Length (cm)
XS	32-35	81-89	26	66
S	35-37.5	89-95	27	69
M	37.5-41	95-104	28	71
L	41-44	104-112	29	74
XL	44-48.5	112-123	30	76
XXL	48.5-53.5	123-136	31	79
3XL	53.5-58	136-147	32	81
4XL	58-63	147-160	33	84
5XL	63-68	160-173	34	86

How it fits: True to size worn solo. Go one size up for the oversized streetwear look or layering over a tee.

MLB Jersey Sizing — Baseball Jerseys

MLB fan version jerseys are button-up with a relaxed, straight cut. Because the front opens, the fit is more forgiving than a pullover; the back half is where your chest measurement matters.

Size	Chest (in)	Chest (cm)	Length (in)	Length (cm)
XS	32-35	81-89	28	71
S	35-37.5	89-95	29	74
M	37.5-41	95-104	30	76
L	41-44	104-112	31	79
XL	44-48.5	112-123	32	81
XXL	48.5-53.5	123-136	33	84
3XL	53.5-58	136-147	34	86
4XL	58-63	147-160	35	89
5XL	63-68	160-173	36	91

How it fits: True to size. The button front gives 1-2 in of natural give, so there is rarely a need to size down.

NHL Jersey Sizing — Hockey Jerseys

NHL fan version jerseys are the roomiest cut we carry — built for the ice, where players pad up underneath. Extra-long sleeves, a big angular shoulder line, and a hem that drops well below the waist.

Size	Chest (in)	Chest (cm)	Length (in)	Length (cm)
XS	34-37	86-94	29	74
S	37-40	94-102	30	76
M	40-43	102-109	31	79
L	43-46	109-117	32	81
XL	46-50	117-127	33	84
XXL	50-55	127-140	34	86
3XL	55-60	140-152	35	89
4XL	60-65	152-165	36	91
5XL	65-70	165-178	37	94

How it fits: True to size unless you want a closer fit — many fans actually size down in hockey. Layer-friendly even at your normal size.

NCAA Jersey Sizing — College Jerseys

NCAA fan jerseys follow the cut of their pro counterparts — college football jerseys wear like NFL, college basketball wears like NBA, college hockey like NHL. Check which sport your team plays and use that league chart.

Size	Chest (in)	Chest (cm)	Length (in)	Length (cm)
XS	32-35	81-89	27	69
S	35-37.5	89-95	28	71
M	37.5-41	95-104	29	74
L	41-44	104-112	30	76
XL	44-48.5	112-123	31	79
XXL	48.5-53.5	123-136	32	81
3XL	53.5-58	136-147	33	84
4XL	58-63	147-160	34	86
5XL	63-68	160-173	35	89

How it fits: True to size, matching the pro-league cut of the same sport. The chart below covers football and basketball cuts.

Soccer Jersey Sizing — Soccer Jerseys

Soccer fan version jerseys are the slimmest cut we carry — athletic and close to the body, just like the kits on the pitch. There is little room for layering; this is a summer-fit jersey.

Size	Chest (in)	Chest (cm)	Length (in)	Length (cm)
XS	32-35	81-89	26	66
S	35-37	89-94	27	69
M	37-40	94-102	28	71
L	40-43	102-109	29	74
XL	43-47	109-119	30	76
XXL	47-52	119-132	31	79
3XL	52-57	132-145	32	81
4XL	57-62	145-157	33	84
5XL	62-67	157-170	34	86

How it fits: Between sizes, size up — the slim cut has no give. Fans who prefer a looser fit regularly go one size up.

Fit Tips & FAQ

The four questions our team answers most.

Between two sizes?

Size up. A slightly relaxed jersey always looks intentional; a tight one never does. (Soccer is the one league where sizing up is almost mandatory — the cut is already slim.)

Do fan version jerseys run big or small?

Neither — they run true to size with a relaxed, everyday cut. Player (on-field / on-court) versions are the slim ones.

Do custom stitched jerseys use the same chart?

Yes. Custom names and numbers follow the exact same league chart as stock jerseys — XS through 5XL.

Will my jersey shrink?

Barely — if you wash cold inside out and hang dry. High-heat drying is what shrinks and cracks graphics.

Men's Buffalo Bills Alternate Game Day Custom Jersey

A Buffalo Bills shirt should outlast a single campaign. This jersey is built for the long version of support - the training sessions, the away trips, the ordinary Tuesdays. Short version: Buffalo Bills jersey in the game day cut, for men, 2026.

What you get

Heat-sealed detail that sits flat on the fabric
Stitched trim on the seams and collar

The Game Day build

The Game Day build is the matchday-facing tier of the range: a performance-weight knit, a close athletic cut, and badge and trim work finished to match what is worn for kick-off.

Care that keeps it new

Cold machine wash, inside out, then tumble dry low.

Fit and sizing

Cut to a standard athletic shape that follows the body without gripping it.

Fan version vs on-field version

Fan version: softer knit, roomier fit, lower price.
On-field version: closer cut, firmer fabric, premium price.
Team colours and crest are the same on both.

Version, sizing and what you are buying

Here is the honest positioning: this is the game day build. Supporter-facing fabric and fit, identical team colours and badge detail, and a price that reflects what it is for - standing in the stands.

The fit is true to a normal sports cut for supporters. Order your usual size for a close-but-comfortable fit, or size up if you prefer something looser.

This one is a custom listing, so a name and number can be set before it ships. Use any player, any squad number, or your own name - the print sits flat and stays sharp.
