How to choose shirt sizes for a group order

If you know who will wear the shirts, ask them for sizes before you order. If you’re buying for an event where you don’t know the attendees, use your own past sales or registration information to build an estimate. A size ratio from the internet can help start that conversation, but it cannot tell you what your particular group needs.

You also don’t need a finished size list just to start planning. Our quote request lets you enter an approximate quantity and confirm sizes later. Keep that estimate separate from the final breakdown used to buy the blanks.

Choose the garment before collecting sizes

“What size shirt do you wear?” is a useful first question. “What size do you want in this shirt?” is a better final one. Give everyone the actual style, fit description and matching size chart. Otherwise, you can end up collecting answers for three different ideas of a medium.

Pick the main style and color first. If you’re still comparing a lightweight tee with a heavier relaxed style, finish that decision before calling the size list final. Our Bella+Canvas 3001 and Gildan 5000 comparison explains the garment differences without asking you to choose by brand name alone.

If the shirt changes after people respond, send the new chart and let them check their selection. Don’t silently carry their answers over to a different cut.

For staff or a known group, collect individual choices

A simple shared form or spreadsheet is enough. Ask for a name, garment choice, adult or youth sizing, requested size and quantity. Add a response deadline so one missing answer doesn’t hold up the whole list.

Keep the information specific. “Two large shirts” is ambiguous when you’re offering both a tee and a hoodie. “Adult unisex tee, large, quantity two” gives you something you can count and check.

Before totaling the order, remove duplicate responses and check anyone who requested several garments. A second response might be a correction, not another shirt. Keep unresolved answers in a separate column instead of guessing what the person meant.

Check what the size chart is measuring

A body-size chart and a garment specification sheet answer different questions. A body chart describes the wearer. A garment sheet describes the shirt. Don’t compare a measurement around someone’s chest directly with a number taken across the front of a flat shirt.

For example, BELLA+CANVAS publishes both a general fit and size chart and a separate 3001 garment measurement sheet. Use the instructions and measurements for the exact style you’re ordering. A familiar shirt can be a helpful reference when measured the same way, but the letter on its tag is not the whole comparison.

For a group with strong fit preferences, ask about the actual garment rather than telling everyone to size up automatically. Someone who wants a closer fit and someone who wants an oversized shirt may choose differently from the same chart.

For an open event, keep the size mix an estimate

If you’re selling shirts at an event, you may not have individual responses to collect. Start with evidence you do have: the previous event’s starting quantities, what sold, which sizes ran out and what remained. Sold-out sizes need special attention because sales alone don’t show how many more people wanted them.

A generic ratio should be a fallback, not a guarantee. Don’t exclude a size simply because an example chart leaves it out. Think about who can attend, what styles you’re offering and whether people can reserve their size ahead of time.

Separate confirmed requests from the unallocated event stock. For a hypothetical 60-shirt order with 42 reservations, you have 18 shirts left to allocate. Keep the 42 actual selections intact and make a deliberate plan for the remaining 18. That is an arithmetic example, not a recommended size distribution.

Keep adult, youth and different styles on separate rows

Youth large and adult large are not interchangeable entries. Neither are a fitted tee, a relaxed tee and a hoodie just because all three say large. Give each garment style and sizing range its own row, then total the pieces across the order.

This matters for artwork too. If the same design goes on adult and youth garments, tell us before the mockup is finalized. Placement and print dimensions need to be checked against the garments, including the smallest one. A shirt-size list does not approve a print size.

Check the totals before buying blanks

• Each row names the garment, color and adult or youth range.

• Size quantities add up to that row’s total.

• The garment totals add up to the full order quantity.

• Unconfirmed sizes are identified instead of mixed into confirmed counts.

• Any extra event stock is separated from named reservations.

Ask us to confirm availability and the complete quote for the final mix. A change in style, color, size range or quantity can affect what is available and how the order is priced. Don’t assume the initial estimate covers a changed list.

Start with what you know

If all you have is “about 50 shirts for an event,” that’s enough to begin a conversation. Send the quantity, date, preferred garment or feel, color ideas and any artwork you have. We can help narrow down the shirt while you collect the size breakdown.

Request a quote with the details you know. You can confirm sizes later, before the order moves ahead.
