Group order size calculator
Ordering shirts for a group and can't collect everyone's size? Enter your headcount and group type and this tool suggests an S–XL breakdown from common group-order size curves — then sends it straight to a free quote.
Why groups over-order M/L — and run out of the tails
The single most common bulk-apparel mistake is ordering an even split — the same number of every size. Real groups don't distribute evenly. Most adult orders cluster in the middle, around L and XL, with fewer at the extremes. Order a flat split and you end up with a stack of XS nobody claims and a shortage of the sizes people actually asked for.
The fix is a size curve: a weighting that puts more of the order in the middle sizes and a sensible tail on either end. This calculator uses the same starting curves published on our size guide — one for mixed adult groups, one for youth-heavy school orders, and one weighted toward the middle for walk-up event giveaways where you can't collect sizes at all. Pick the closest match, enter your headcount, and you'll get a breakdown that's far closer to reality than an even split.
It's a starting point, not a spec. Whenever you can, collect real sizes — a quick form beats any curve. But when you can't, or you just need a defensible number to price against, this gets you close. For the whole approach, including how to run a size-collection form, see our guide to collecting team apparel sizes.
A common starting split for a mixed adult group. Most orders center on L and XL; adjust up a size for older or larger groups, down for youth-heavy ones.
