Size Guide

Last updated: November 8, 2026

A jersey that fits feels better, looks better in photos and moves with you when you swing, shoot, skate or sprint. Jerz Hub sells jerseys for five sports, and each sport is cut a little differently: hockey sweaters are roomy so they slide over pads, basketball jerseys hang loose under the arms, and baseball tops are shaped for a full throwing motion. This guide explains how to choose a size with confidence, without relying on a label that varies from brand to brand. The sizes available for each jersey are always listed in the size menu on its product page, and you can email [email protected] for a personal recommendation before you order.

Why we measure a jersey rather than a body

Most people already own a top that fits them well. Measuring that garment tells you far more than a tape around your chest, because it already includes the amount of ease you like: snug, regular or roomy. Size labels differ between makers, so “Large” from one shop may be closer to “Medium” from another. When you compare a garment you trust with ours, you avoid that problem. OWNER_CONFIRM: a garment measurement chart per style will be added here once confirmed with the production partner; until then this guide gives method and advice only and does not quote numeric measurements.

How to measure a jersey you own

1. Lay it flat. Put the jersey face up on a table or the floor, buttoned or zipped if it has a front closure. Smooth out wrinkles without stretching the fabric.
2. Chest width. Measure straight across the front from one side seam to the other, about one inch below the armholes. This is the half-chest measurement; doubling it gives the full circumference.
3. Body length. Measure from the highest point of the shoulder, where the collar meets the shoulder seam, straight down to the bottom hem. For a jersey with a curved or dropped back hem, measure the front.
4. Sleeve, if it matters to you. For hockey and baseball styles, measure from the shoulder seam to the end of the sleeve.
5. Write the numbers down in inches or centimetres, and note what you like or dislike about the fit, for example “a bit tight across the shoulders”.

Email those numbers to [email protected] with a link to the Jerz Hub jersey you are looking at, and we will reply within 24 hours on business days with the size we suggest.

If you prefer to measure yourself

If you do not have a jersey to compare with, measure your body instead and tell us the numbers:

• Chest: wrap a soft tape measure around the fullest part of the chest, under the arms, keeping it level and snug but not tight.
• Height: useful for judging length, especially for tall players.
• Equipment: say whether the jersey will be worn over shoulder pads, chest protectors or other gear.

We will use those details, together with the style you have chosen, to recommend a size.

Advice by sport

Baseball jerseys

Baseball tops are cut to allow a full throwing and batting motion through the shoulders. Many players wear them over a fitted base layer. If you sit between two sizes and like room to swing, go for the larger one; if you prefer a neat look tucked into trousers, the smaller of the two is usually better. Browse Custom Baseball Jerseys.

Softball jerseys

Softball styles follow the same reasoning as baseball. Think about whether you will tuck the jersey in and whether you wear a layer underneath. Players who slide often tend to prefer a slightly longer body so the jersey stays tucked. See Custom Softball Jerseys.

Football jerseys

Football jerseys are designed to look good with or without shoulder pads. For casual wear, game days or flag football without pads, choose your usual size. If you will wear full pads, compare the chest width of a jersey you already wear over pads, or ask us before ordering. See Custom Football Jerseys.

Basketball jerseys

Basketball jerseys are sleeveless and meant to hang loosely so they do not restrict the arms. Choose your usual size for a relaxed fit. Size down only if you prefer a close fit, and keep in mind that wide armholes are part of the style. See Custom Basketball Jerseys.

Hockey jerseys

Hockey sweaters are deliberately roomy because they go over shoulder pads, elbow pads and a neck guard. For on-ice use, your usual size is normally right. If you will wear the jersey only as a casual top without equipment, it will feel generous, and some people prefer one size smaller. Sleeves are long so they cover elbow pads. See Custom Hockey Jerseys.

Blank jerseys

Our blank jerseys use the same sport cuts as the custom ones, just without any decoration, so the same advice applies. Coaches ordering for a group should check each player’s size rather than ordering one size for everyone. See Blank Jerseys.

Adult and youth sizes

Where a jersey is offered in both adult and youth sizes, the two are listed separately in the size menu. Youth sizes are for children and younger teens, and their proportions are different from simply smaller adult sizes. For a child who is growing quickly, many parents choose the next size up so the jersey lasts the season. If you are ordering for a child, measure a top that fits them now and email us the numbers.

Choosing between two sizes

• Size up if you wear equipment underneath, like a relaxed look, have broad shoulders or want room to grow.
• Stay with the smaller size if you prefer a close fit, will tuck the jersey in or plan to wear it without layers.
• Ask us if you are still unsure. A quick email with your measurements saves you a return later.

Sizing for a team

When you order jerseys for a group, collect each person’s size before you start adding items to the cart. A simple method is to pass one jersey around and let everyone say whether it fits, is too small or is too big. Add one jersey per player, with that player’s size, name and number. If you have a long roster or mixed adult and youth sizes, email us the list first and we will help you check it.

Personalisation and size

Names and numbers are placed to suit the size you choose, so a long surname on a small jersey still fits within the back panel. Check the live preview on the product page as you type; it shows roughly where the text will sit. We print exactly what you enter and do not send a proof before production, so make sure the size and the text are both right before checkout. If you notice a mistake, email us within 24 hours of ordering; see Cancel or Change an Order.

If the size is not right

Do not worry if the jersey does not fit. You have 60 days to return it. For a change of mind, including a size that is not right, we send a free return label. Tell us whether you want a different size, a refund or store credit; refunds are sent within 7 days of the return reaching us, and store credit never expires. Full details are on our Returns & Exchanges Policy page.

Care and fit over time

How a jersey is washed and dried can affect its fit and the printed text. Follow the care instructions on the garment label. If a product page does not give care details, wash inside out in cool water and avoid high heat as a general precaution, and email us if you have a specific question. OWNER_CONFIRM: per-product care instructions.

Common sizing questions

Do your jerseys run small or large?

That depends on the sport, which is why this guide gives advice by sport rather than one rule for all. Hockey and basketball styles are naturally roomy; baseball and softball styles are more tailored. Comparing with a jersey you already own is the most reliable way to judge.

Are your sizes unisex?

Unless a product page states otherwise, our adult sizes are a standard athletic cut that many people of all genders wear. If you usually wear a fitted women’s cut, consider whether you like a relaxed look; if not, compare measurements with a top you own or ask us.

Can I order different sizes in one order?

Yes. Each jersey in your cart has its own size, name and number, so a family or team can order several sizes together. Add each jersey separately with its own details.

Will the name fit on a small size?

The fields on each product page limit the number of characters so that the text fits the back panel. Long names are set to suit the space. Check the live preview as you type.

Can I exchange for a different size?

Yes, within 60 days, with a free return label for change of mind. Email us with your order number and the size you want instead. A personalised jersey in a new size is printed again with the same name and number.

Measuring tips that save returns

• Use a soft tape measure. A metal tape or ruler bends badly around a garment and can add errors.
• Measure twice and use the average if your two readings differ.
• Do not stretch knitted or mesh fabric while measuring; let it lie naturally.
• Measure the jersey you actually like wearing, not the one at the back of the drawer.
• For children, measure a top that fits now, then decide how much growing room you want.

Fit words we use on product pages

• Relaxed means extra room through the body and arms, typical of basketball and hockey styles.
• Regular means a standard athletic fit with some ease, typical of football and many baseball styles.
• Room for pads means the cut is meant to go over equipment, so it will feel generous without it.

If a product page does not use one of these words, treat the advice for its sport above as the starting point and ask us if you are unsure.

A note on layering

Think about the weather and season when you choose. A baseball or softball jersey worn over a long-sleeve base layer in early spring needs a little more room than one worn on its own in summer. A hockey sweater over full equipment needs the space it was designed with. A basketball jersey worn over a T-shirt for a casual game may feel tighter around the armholes. When in doubt, tell us how you plan to wear it and we will recommend a size.

Remember that the size you pick also decides how the name and number are scaled, so a correct size gives the cleanest result on the back.
