Size Guide

Last updated: 14 November 2026

This guide helps you choose a size for a Teach Tee tee or crewneck sweatshirt, for yourself or for a whole grade team. We will be straight with you first: we have not published a measurement chart yet. We only want to print numbers we have confirmed for the exact garments we sell, and that work is not finished. Until it is, this page gives you a reliable method that does not depend on a chart, and our returns policy covers the rest: if the size is wrong, you have 60 days from delivery and a free return label. Questions go to support@teachtee.shop, and we reply within 24 hours on business days.

The sizes we sell

Every tee and every crewneck sweatshirt comes in the same eight adult sizes. The names below are exactly the names on the size buttons on each product page.

These are adult sizes. We do not sell youth or student sizes, so please do not order an S hoping it will fit a child. Tote bags, tumblers and the gift set have no size option at all.

Why there are no measurements on this page

A size chart is a promise. If we printed chest and length figures here and the shirt in your parcel measured differently, the chart would have misled you. So the figures stay off the page until they are confirmed, and we flag that openly instead of filling the gap with typical numbers copied from somewhere else.

The same goes for how a garment is cut, what it is made of, whether it shrinks and how to wash it. We do not describe those here. If one of them decides your order, email us and ask about the exact product. We will tell you what we know and say so when we do not know.

How to measure a shirt you already own

The most dependable guide to your size is a shirt in your drawer that fits the way you like for a school day. You are not measuring your body. You are measuring a garment you trust.

1. Pick the right shirt. Choose a plain crew-neck tee you would happily wear on a spirit day Friday. Not your tightest, not the one you paint in.
2. Lay it flat. Use a table or the floor. Smooth it out without stretching it. Button nothing, tuck nothing.
3. Measure the width. Run a tape straight across the chest from one side seam to the other, just below the sleeves. Write the number down.
4. Measure the length. Run the tape from the highest point of the shoulder, beside the collar, straight down to the bottom hem. Write that down too.
5. Read the label. Note the size printed in the collar. That label, together with how the shirt fits you, is your starting point.

With those three notes you can do two useful things today. You can order the size on that label with more confidence than a guess. And you can email us your two measurements and the product you are looking at, and ask which of our sizes is closest. That is a question we can answer for one product at a time, even before a full chart is published.

No tape measure in the classroom? A ruler works. So does a strip of paper marked with a pencil and measured later.

Choosing between two sizes

Many people sit between two sizes. A PE teacher who wears L in some shirts and XL in others is the usual case. Without a chart, decide by how you will wear it rather than by the letter.

If you still cannot decide, order the size you wear most often in other shirts. Should it turn out wrong, the swap is free. Please do not order two sizes “to compare” on a tight deadline, though. A return takes time to travel, and the 17 business days for a new order start again.

Tee or crewneck sweatshirt

A tee and a crewneck sweatshirt are different garments, and people often want them to fit differently. A sweatshirt usually goes over something, and a tee usually goes under something or stands alone.

• If you measured a tee from your drawer, use it to choose a tee. For the sweatshirt, measure a sweatshirt you own in the same way.
• If you want the sweatshirt to sit over a collared shirt on a cold morning duty, think about the layer when you choose.
• Do not assume your tee size and your sweatshirt size are the same letter. For many people they are. For some they are not.
• A grade team can mix the two. Four tees and two sweatshirts still read as one team in the photo when the design matches. Compare what is offered in Teacher Tees and Teacher Sweatshirts.

How a grade team collects sizes

Team orders go wrong in one place: the list. Someone says “medium, I think” in the hallway, and it is typed as M three weeks later. Here is a routine that takes one planning period.

1. One person holds the list. Usually the team lead or whoever is placing the order. Nobody else edits it.
2. Ask in writing. Send one message: the design, tee or sweatshirt, and “reply with your size from S, M, L, XL, 2XL, 3XL, 4XL, 5XL”. Written replies end the “I thought I said large” conversation.
3. Send this page with the question. Anyone unsure can measure a shirt at home that evening.
4. Set a reply date. Work back from your day. The order should be placed 17 business days before it, so ask for sizes a few days before that.
5. Read the list back. Before you open the cart, send the full list to the team once: name, garment, size. Give them a day to correct it.
6. Add to the cart from the list, top to bottom. One line per teacher. Check the cart against the list before you pay.
7. Keep the list. When the parcel arrives, it tells you which shirt is whose.

Remember the people who are easy to miss: the para who works in two rooms, the long-term sub, the student teacher, the specials teacher who has adopted your grade. Ask them too before the order goes in. Adding one shirt later means a separate order with its own 17 business days.

If you find a mistake after ordering, you have 24 hours to email us and change a size. See Cancel or Change an Order.

Buying a shirt as a gift

A room parent rarely knows a teacher’s size, and asking spoils the surprise. Three ways around it:

• Ask her teammate or the para in her room. They often know, or can find out quietly.
• Choose a gift with no size. A tote or a tumbler from the teacher bag fits every teacher.
• If you do order a shirt, tell her it can be swapped. She has 60 days from delivery, and the return label is free.

If the size is wrong when it arrives

Try it on soon after it arrives, not on the morning of the 100th day. If it does not fit:

1. Email support@teachtee.shop within 60 days of delivery. Give the order number, the item and the size you would like instead.
2. We send a free return label. You do not pay postage, even though the shirt itself was fine.
3. Post the shirt back. Your refund is sent within 7 days of our receiving the return, to the original payment method, or you can take store credit that never expires.
4. For the new size, the returns page explains how an exchange runs. If your day is close, tell us and we will explain the quickest route.

This applies to every tee and sweatshirt, including the personalised name tee. There is no restocking fee. The full process is on Returns & Exchanges, and the money side is on the Refund Policy.

Five sizing mistakes we see

• Measuring a favourite old shirt. A tee that has been washed for years may no longer match its label. Measure one that is fairly new.
• Choosing by the letter you wore years ago. Go by the shirt that fits you this term.
• Ordering for a teammate from memory. Ask her in writing. It takes one message.
• Leaving the try-on until the day. Try it the week it arrives, while a free swap still has time to travel.
• Assuming labels mean the same everywhere. Teachers in Australia and New Zealand often shop by number sizes at home. Our buttons use letter sizes only, S to 5XL, so compare with a letter-sized shirt you own or email us for help.

None of these is serious, because the 60-day return covers all of them. They only cost time, and time is the one thing a fixed school day does not give back.

Totes, tumblers and the gift set

These have no sizes. Each is sold in a single size, so the only choices are the design and, on the personalised ones, the name and the grade or role. We have not published dimensions or capacity for them yet, for the same reason we have not published a shirt chart. If you need to know whether a tote takes a laptop or a stack of composition books, or whether a tumbler fits a particular cup holder, email us and ask about the exact product before you order.

Questions we get about sizing

Do the larger sizes cost more?

The price for each size is shown on the product page when you select it. What you see there is what you pay, and shipping is free.

Will the print be the same on an S and a 5XL?

The design is the same. How large it appears against the shirt can differ between the smallest and largest sizes. If that matters for a team photo, ask us about the specific design.

Can I get a size outside S to 5XL?

Not at the moment. Those eight sizes are the full range, and they are the same on every tee and every crewneck sweatshirt, so nobody on the team is left with a different design because of her size.

When will the measurement chart be added?

When the figures are confirmed for the garments we sell. We would rather the page stay honest than look complete. The date at the top of this page changes when the chart goes in.

Ask us before you order

Email support@teachtee.shop with the product name, the size you usually wear and, if you have them, the two measurements from a shirt you own. We reply within 24 hours on business days. If you are ordering for a team, send one email with the whole list and we will answer for everyone at once. For timing, see Shipping & Delivery. For quick answers, see the FAQs.
