How to Collect Shirt Sizes for Your Group (The Complete Guide)

Why Collecting Shirt Sizes Is Harder Than It Sounds

You've decided to do group shirts — a reunion tee, a bachelorette party look, a team uniform, or company swag. Exciting. But then reality sets in: you have 40 people to coordinate, everyone is busy, and you just need one simple piece of information from each of them: their shirt size.

It should take five minutes. Instead, it takes two weeks of follow-up texts, a spreadsheet full of holes, and at least one person who ends up with the wrong size because they said "medium" but meant "women's medium" — which is completely different from a unisex medium.

Sound familiar? You're not alone. Collecting shirt sizes from a group is one of those tasks that looks trivial on paper but falls apart in execution. The problem isn't your group — it's the tools most organizers reach for. They're designed for other jobs, and shirt-size collection just doesn't fit neatly into any of them.

In this guide, we'll walk through every common method for collecting group shirt sizes — from the old-school text-message approach all the way to purpose-built tools — and help you pick the one that's right for your situation. Whether you're organizing 10 people or 200, there's an approach that will save you time and frustration.

Method 1: Text Messages & Email

The most natural first instinct: just text or email everyone. "Hey, what size shirt do you wear?" Easy, right? For a group of five close friends, this genuinely works fine. For anything larger, it quickly becomes a part-time job.

How it works

You send a message to each person individually (or to a group chat), wait for replies, then manually track each response in a list or your memory. When someone doesn't reply, you chase them down. When they reply with something ambiguous — "medium-ish" or "whatever fits" — you follow up again. Rinse and repeat until you have every last size.

Pros

• Zero setup time — you're using tools you already have
• Works for very small groups (under 10 people)
• Direct, personal communication

Cons

• Responses are scattered across multiple conversations, DMs, and inboxes — impossible to keep organized
• Manual data entry into whatever tracking system you're using, introducing typos and errors
• No size chart — people guess their size, and guesses are often wrong
• No structure forces people to give you a clean, usable answer
• Follow-ups are entirely manual; nothing reminds stragglers automatically
• Totaling up sizes (how many mediums? how many XLs?) means counting by hand

Best for: Groups of fewer than 8 people who all respond quickly and are low-maintenance.

Method 2: Spreadsheets (Google Sheets / Excel)

The next step up: a shared spreadsheet. You create a Google Sheet or Excel file with columns for Name, Size, and maybe Style, then share it with your group and ask everyone to fill in their row. It sounds organized, and it is — at least in theory.

How it works

You set up a spreadsheet with a clear layout, share the link, and give everyone edit access. People find their name (or add it themselves), type in their size, and you watch the sheet fill up over time. When it's done — or when your deadline arrives — you total up the sizes and place your order.

We've put together free templates for this exact setup: see our free t-shirt size collection spreadsheet templates.

Pros

• More organized than scattered messages
• Centralized — everything lives in one place
• You can use formulas to count sizes automatically
• Free with Google or Microsoft accounts

Cons

• Many people don't fill it out without repeated reminders — "I'll do it later" is death for group spreadsheets
• People can accidentally delete or overwrite other rows
• No size chart within the spreadsheet — people still have to guess
• Editing access means anyone can see everyone else's data, which some people dislike
• Still requires manual counting and double-checking before ordering
• Not mobile-friendly — editing a shared spreadsheet on a phone is clunky

Best for: Groups of 10–30 where most people are tech-comfortable and you're willing to do some manual follow-up.

Method 3: Google Forms

Google Forms is a genuine step forward in structure. Instead of asking people to edit a shared document, you send them a link to a form. They fill it out, hit submit, and their response is recorded automatically. No accidental overwrites, no messy threads of replies.

How it works

You create a form with fields for name, email, and a size dropdown (S, M, L, XL, 2XL, 3XL). You share the link. Responses automatically flow into a linked Google Sheet that you can review at any time. When the deadline hits, you export or read from the sheet and calculate your order quantities.

Pros

• Clean, structured responses — no accidental overwrites
• Works well on mobile
• Automatic response collection into a Google Sheet
• Free
• Can add basic validation (required fields, etc.)

Cons

• No size chart — people still guess, leading to wrong-size orders after shirts arrive
• No real-time dashboard showing who has and hasn't responded
• No automatic reminders for non-responders
• Manually calculating totals (how many of each size?) still requires spreadsheet work
• No connection to any ordering system — data collection and ordering are entirely separate steps
• No way to handle style preferences or gender-specific sizing elegantly

Best for: Groups of any size that need something more structured than a spreadsheet but don't mind a manual data-to-order workflow.

Method 4: Dedicated Size Collection Tools (Like GGROUPT)

The fourth — and most efficient — approach is a tool built specifically for the job. These aren't general-purpose form builders or spreadsheet apps repurposed for shirt sizes. They're designed from the ground up to handle the exact problem you're solving: getting accurate sizes from a group of people so you can place a correct, on-time order.

How GGROUPT works

As the organizer, you create a collection campaign in GGROUPT and choose the shirt style your group will be ordering. GGROUPT generates a unique shareable link — the same kind of link you'd send in a text or a group chat. When a group member clicks it, they land on a clean, mobile-friendly page that shows them:

• The actual shirt style they'll be receiving
• A visual size chart with real measurements so they can pick accurately
• A simple selection interface — tap your size, submit

On your end, you get a real-time dashboard showing every response as it comes in. You can see at a glance who has responded and who hasn't, and the tool automatically totals up sizes for you — no counting required.

When collection closes, your size breakdown is ready to go directly into your order. If you're ordering through GGROUPT's integrated catalog, you can move from collection to order in minutes — no copy-pasting, no manual re-entry.

Whether you're planning family reunion shirts, bachelorette party shirts, or company apparel, the workflow is the same: share a link, watch sizes come in, order.

Pros

• Visual size charts built in — members pick the right size, not a guess
• Real-time dashboard — see who's responded and who hasn't, instantly
• Automatic size totals — no manual counting
• Mobile-first — members submit in 30 seconds on any device
• Directly connected to ordering — no copy-pasting data
• Purpose-built — every feature is designed for this exact task

Cons

• Requires signing up for an account (free)
• Slight learning curve compared to tools you already know

Best for: Any group of 10 or more where accuracy matters, you want real-time tracking, and you don't want to spend hours chasing people or manually tallying sizes.

Tips for Getting Everyone to Respond Quickly

Regardless of which method you choose, the biggest challenge is the same: getting people to actually respond. Human nature being what it is, people deprioritize tasks that don't feel urgent — especially if clicking a link or filling something out takes more than 60 seconds. Here are strategies that actually work:

Set a firm, specific deadline

"ASAP" doesn't work. "By Thursday at noon" does. Be specific and tie it to a real consequence ("I have to place the order by Friday or we won't get shirts in time"). Deadlines with stakes get responses.

Make it as easy as possible

Every extra click or field kills response rates. The simpler the process, the faster people will complete it. This is one of the core reasons purpose-built tools like GGROUPT outperform generic forms — the member experience is optimized to take under a minute.

Send to the right place

Drop the link where your group already lives: the group chat, the family Facebook group, the team Slack. Don't make people check their email if they rarely do. Meet them where they are.

Send a reminder — one, then two

A friendly nudge 48 hours before the deadline, and a final one the morning of, will dramatically increase completion rates. Keep the tone light and personal, not nagging.

Use social proof

"30 out of 40 people have already submitted — can you be next?" People respond to knowing others have done it. If your tool shows a real-time count, share it in the group chat.

Have a fallback plan

Decide in advance: if someone doesn't respond, what do you do? Order them a medium? Skip them? Knowing your plan removes the anxiety of chasing down the last few holdouts.

What to Do After You've Collected Sizes

You've got all your sizes. Now what? Here's the standard order flow for group shirts:

1. Verify your totals

Double-check your size counts before placing any order. Common mistakes include counting the same person twice, missing a late submission, or mixing up men's and women's sizes. If you used GGROUPT, your dashboard does this automatically — no manual verification needed.

2. Confirm your shirt style

Make sure the style you're ordering has all the sizes you need in stock. If you need 3XL or tall sizes, check availability before finalizing. For a deep dive into sizing, see our complete t-shirt size chart guide.

3. Get a sample if the budget allows

For large orders, ordering a sample blank shirt in the style you've chosen lets you verify the actual fit before committing. Sizing can vary meaningfully between brands — a Bella+Canvas medium fits very differently from a Gildan medium.

4. Finalize your design

Sizes and design can be finalized in parallel, but you need both before placing an order. Make sure your design is high-resolution (300 DPI minimum) and properly formatted for the print method you're using.

5. Place the order

If you're using GGROUPT, your collected sizes flow directly into the order — no copy-pasting required. If you're using another vendor, you'll need to enter your size breakdown manually. Either way, review everything once more before submitting.

6. Communicate the timeline

Let your group know when to expect shirts. People appreciate being kept in the loop, and it cuts down on the "where are my shirts?" questions during production.

Conclusion

Collecting shirt sizes from a group doesn't have to be painful. If you're organizing a very small group of close friends, a quick text works fine. For anything larger — and especially when accuracy matters — you need a more structured approach.

Spreadsheets and Google Forms are a meaningful improvement over message threads, but they still leave you doing manual work and chasing people who forget to fill things out. They also don't solve the root cause of wrong-size orders: people guessing their size without a real size chart in front of them.

Purpose-built tools like GGROUPT exist precisely to fix these problems. Members get a size chart when they pick, you get a live dashboard as responses come in, and your totals calculate automatically. Setup takes two minutes, and the whole group is done in a fraction of the time it takes with any other method.
