Size Guide

Last updated: 12 November 2026

The best size chart you own is already in your drawer: the shirt you reach for on game day because it simply fits. This guide shows you how to measure that shirt, how to compare it with ours, and how a squad organiser can collect sizes from a whole roster without a single “wait, did you say L or XL?” We do not publish a measurement chart on the site yet. Instead, send us your measurements and we will reply with the exact garment measurements for the shirt you are looking at.

Sizes and add-ons at a glance

All sizes are adult sizes, in one size row from S to 5XL. Sleeve options can vary slightly from shirt to shirt, so the product page is always the final word on what each one offers and what it costs.

How to measure a shirt you already own

You need a tape measure (a long ruler or a piece of string works too), a flat surface like a table or the floor, and the shirt that fits you the way you like. A sports top is ideal; a regular tee is fine if that is the fit you want.

1. Lay it flat. Put the shirt face up on the flat surface. Smooth it out with your hands so there are no folds or ripples, but do not stretch it.
2. Measure the chest. Find the two points where the sleeves meet the body, right under the arms. Measure straight across from armpit to armpit. That is the chest width.
3. Measure the body length. Find the highest point of the shoulder, where the shoulder seam meets the collar. Measure straight down to the bottom hem. That is the body length.
4. Write both down with the size on the label. For example: “my current shirt is a size L, chest so-many, length so-many”.
5. Email us. Send the two measurements, the size you are considering and the shirt you want to support@backheel.shop. We reply within 24 hours on business days with the exact garment measurements so you can compare like for like.

Measure in the units you are used to, inches or centimetres, and say which one you used. Measuring a garment flat is more reliable than measuring your body, because it already includes the room you like to have when you play.

Choosing between two sizes

If your measurements sit between two of our sizes, think about how you actually wear the shirt.

• Layers underneath. Wear a base layer or a thermal under your jersey on cold winter courts? Go for the bigger of the two.
• Keepers. Keepers dive, reach and often wear padding underneath, so many prefer room in the body and arms. Size up if in doubt.
• Off the court. Buying the art to wear out rather than to play in? Pick the size you would choose for a regular tee you like.
• Shorts. Choose by the size you normally buy in shorts, and compare with a pair you own if you are unsure.
• Still torn? Email us both measurements. Seeing the real garment numbers usually settles it in one message.

If it turns out wrong anyway, you are not stuck with it. See the section on size swaps below.

Collecting sizes from a whole squad

A squad of six to ten players is where sizing goes sideways: one person replies with a size, another with a number, someone else with a thumbs-up. Send one message to the group and ask everyone to answer in the same order on one line:

1. Name as it should appear on the back, up to 12 letters (it will be printed in capitals).
2. Number, from 0 to 99, and check nobody else has it.
3. Size, from S to 5XL.
4. Sleeves: Short or Long.

A reply then looks like this: “RIVERA, 9, L, Short”. Copy each line straight into a shirt in the cart. When you are done, the cart repeats NAME · NUMBER under each shirt, so you can read the roster back against the message thread before you pay. Set a deadline in your message a few days before your order date. With winter registration running from September to November and first games often in January, an early deadline gives you room to order at least 17 business days ahead.

Tip for organisers: ask anyone unsure of their size to measure a shirt they own using the steps above and send you the two numbers. Forward those to us in one email and we will reply with the garment measurements for each.

Sleeves: short, long and sleeveless

Short sleeves

The standard pick for most court art jerseys and the usual choice for outfield players: the pivo (your target player up front), the two alas (the wingers) and the fixo (the last player at the back). Short sleeves are included in the base price.

Long sleeves

Available on most jerseys for $5 more. Popular with keepers, with players on cold courts in winter, and with anyone who wants the all-over pattern running down to the wrists. The Rain or Shine keeper jersey is long sleeve only. When you mix sleeves in one squad order, the sleeve choice is set per shirt, so each player can pick their own.

Sleeveless

The Fence Line street jersey is sleeveless, made for summer blacktop and pickup games where winner stays on and nobody wants to sit out. It is a set design, so it does not take a name or number. Size it like your usual sleeveless top; if you have none, measure a tee you like for the chest and length, and mention that it is a sleeveless shirt you are comparing against when you email us.

Socks sizes

The Gym Floor Lines crew socks come in two sizes: S/M and L/XL. Pick the one that matches the shoe size range you normally buy socks in. If you sit right at the border between the two, email us your usual sock size and we will help you choose. Socks are a set design, with no name or number.

Names, numbers and add-ons

Personalisation is not a size, but it changes what you see on the back, so it belongs here too.

• Name on back: up to 12 letters, printed in capitals. Optional on most jerseys, required on the three Custom shirts.
• Number on back: 0 to 99. Optional on most jerseys, required on the Custom shirts.
• Front chest number: a small number on the front, $3, available on the Custom Flying Keeper, Custom Free Agent and Custom Back Heel Name Bar shirts.
• Name bar colour: on the Name Bar shirt only, choose Mustard or Concrete for the bar behind the name.
• Plain back: leave the name and number empty on an optional jersey and the back panel stays plain.

Every pattern keeps a calm back panel behind the name and number, so they stay readable for the referee and the bench whatever the size. The pattern itself runs round the front, back and sleeves. On the product page, the turntable shows your name and number live on the back as you type, and the “Read the back out loud” line repeats them, so check spelling there before you add the shirt.

Names and numbers are personal only. We do not print team, league, club, college or country names, crests or logos, or player, character or brand names.

Keepers and clash colourways

Sizing a keeper is the same as anyone else, but the shirt needs to look different from the four outfield players. Pick a clash colourway of your squad’s pattern, or one of the Keeper Shirts. If your team plays a flying keeper, the outfield player who steps up as an extra attacker, the Custom Flying Keeper shirt has a required name and number in the same S to 5XL size row.

Size swaps after the shirt arrives

Ordered the wrong size? Every product can be returned within 60 days of delivery, including for the wrong size, and personalised shirts follow the same rule. We email you a free return label, and there is no restocking fee.

1. Email us with your order number and the size you need. A subject like “Order #1234 — size swap” is perfect.
2. We send a free return label for the shirt that does not fit.
3. Place a new order for the right size, with the same name and number if it is personalised.
4. Once your return reaches us, the refund for the first shirt is sent within 7 days, or you can ask for store credit, which never expires.

Caught it before it shipped? Within 24 hours of ordering you can simply change the size by email, with no return needed. See Cancel or Change an Order and the Returns & Exchanges Policy for the details.

Common sizing questions

Is there a youth or kids range?

Not at the moment. Every shirt, short, tee and hoodie comes in adult sizes from S to 5XL. If you are ordering for a younger player, compare one of their own shirts with our garment measurements by email before you order.

Can everyone in the squad wear a different size in the same colourway?

Yes. Size, sleeves, name and number are chosen per shirt, so a roster can run from S to 5XL in one shared colourway, with the keeper in a clash colourway of the same art.

Do my shorts have to match my shirt size?

No. Shorts are their own product with their own size choice. Many players wear a different size top and bottom, so pick each one on its own.

Can I order two sizes and send one back?

You can. Every product can be returned within 60 days of delivery with a free label from us. If the shirts are personalised, remember each one is made with the name and number you typed, so it is often simpler to ask us for garment measurements first.

Where can I check the size I picked after ordering?

Your size, sleeves, name and number are listed for each shirt in the order confirmation email. If you checked out with an account, they also show under Orders in My Account. Read them as soon as the email lands: within 24 hours you can still change a size by email.

I have no shirt to measure. What now?

Borrow one from a teammate whose fit you like, or measure any tee you are happy wearing. The point is to give us two real numbers from a real garment. If that is not possible, email us your usual size in sports tops and how you like it to fit, and we will help you choose.

Care

Follow the care label inside the garment. If anything on the label is unclear, email us and we will help.
