24 minimum. 100 is the usual first order.
The curve changes because the audience does.
Each colour needs its own curve.
| Size | Pieces | Share | Ext. size? |
|---|
The curve is a starting point, not a rule. If you know your audience — a gym skews L/XL, a school event skews M/L, a running club skews S/M — move 3–5 pieces between sizes rather than adding more. Prices shown are 2026 list prices for 230gsm US stock; extended sizes carry the mill surcharge shown. Minimum order is 100 pieces per style and colour.

How the curve is calculated
Each audience has a different peak. Unisex adults cluster at M and L; streetwear shifts the mass up to L, XL and 2XL because the fit is worn loose; women's cuts peak one size lower; kids' sizes follow school-age distribution rather than adult body size. The tool takes the shape, multiplies by your quantity, and then rounds so the total is exactly your number — not 99, not 101.
The rounding method matters more than it sounds. Rounding each size independently is how you end up one shirt short on an invoice, or paying for a piece you did not order. The tool uses largest-remainder rounding, which distributes the leftover pieces to the sizes closest to rounding up.
How to read the result
- Smalls are the size you will regret. If the tool says 10 and you buy 25 because "it is cheaper per unit", you have converted $58 of stock into a box.
- 2XL is not optional. It is a small share with a higher price, and it is the size that wins repeat customers among bigger buyers.
- Two colours means two curves of half the size. It also usually means you fall back to the lower quantity tier, so the per-piece price goes up — the tool shows you the price for the total quantity, so halve it yourself when pricing each colour.
