How To Measure
Use a soft tailor's tape and stand naturally relaxed. If you are between two sizes, prioritize your chest circumference.
Chest Circumference
Measure horizontally around the fullest part of your chest, keeping the tape snug, level, but not restrictive.
Waist Line
Measure around your natural waistline, typically situated right above your hip bones.
Back Length
Measure straight from the highest shoulder point downwards to where you want the bottom jersey hem to fall.
Sleeve Reach
Measure from the center back of your neck, over the shoulder ridge, down to your wrist bone.
Fit By Sport
Chest dimensions are consistent across our catalog, but athletic cuts vary by sport. Here is how each league style sits on body:
Soccer / Football
Tailored close to the body. Take your standard size for match wear; size up one if wearing over hoodies.
NBA Basketball
Roomy by design with wide armholes. Your normal size gives comfortable ease; size down for a tighter aesthetic.
NFL Football
Engineered with room for base layers or streetwear tees. If you sit between two sizes, choose the larger.
NHL Hockey Sweaters
Breakaway fits run loose; authentic player editions sit closer. Always verify chest span prior to selection.
MLB Baseball
Traditional button-downs feature an open, boxy cut. Size down one for a streamlined, modern street profile.
Custom Name & Number
Custom printing does not alter garment proportions. Simply order by your standard chest measurement.
Common Sizing Questions
Quick answers regarding fit, editions, and swaps.
Do these measurements match the size options on the product page?
Yes. The chest ranges shown here are taken directly from the size options on our products, so if a size says 41–44 in on the product page, it is the same L in this chart.
Do Game, Limited and Player Edition versions use the same size scale?
Yes. Every version we sell is listed on the same scale, so your size does not change between them. What changes is how the jersey sits on you: player edition styles are cut closer to the body, while game and breakaway versions are cut looser. Between sizes on a player edition? Take the larger one.
I am between two sizes. Which one should I select?
Take the larger one for a relaxed or layered fit, the smaller one if you want the jersey to sit close to the body. Football shirts and player edition styles are cut slimmer, so most people size up once there.
Do personalised jerseys fit differently?
No. Adding a name and number does not change the cut, so choose your size exactly as you would for a blank jersey.
Will my size be the same across brands and leagues?
The chest ranges in this guide are standardised across our range, so your size stays consistent from one league to another. The fit notes above cover the differences in cut.
What if it still does not fit upon arrival?
Get in touch within the returns window and we will help you exchange it. Unworn, unpersonalised items are the easiest to swap.
