Total programme

⚠️ Indicative starting curves, not a rule. These splits are common US wholesale planning defaults — your customer base, fit block and channel (DTC vs boutique) all shift the curve. After your first season, replace the default with your own sell-through data. Units are rounded to whole pieces and always sum to your exact quantity.

How to use a size curve well

01

Start with a curve, refine with data

A first order has no sales history, so a standard curve is the honest starting point. From the second order on, your own sell-through is the only curve that matters — reorder to it.

02

Knitwear is knit to size

Flat knitwear is knitted to shape from a per-size machine programme — no fabric markers, no lay plans. That's why a size run with 25 units of XS is routine here, while the same split can be a problem in cut-and-sew.

03

The minimum is per colour and per size

Our 250 MOQ applies to each colour-and-size combination — every size is its own machine programme. So one navy colourway across XS–XL is five 250-piece programmes; this planner sets the ratio between sizes above that floor.

04

Don't over-buy the tails

XS and XL sell slowest for most brands. Keeping tails lean and restocking core sizes (65–80 days on a repeat programme) beats guessing big on every size up front.

Frequently Asked Questions

What is a size run (size curve) in clothing production?

A size run is how the units in a production order split across sizes — e.g. 250 pieces of one colourway spread over XS to XL. The percentages behind that split are the size curve. Factories knit against the size run you give them, so getting the curve roughly right decides whether you sell out of M while sitting on unsold XS.

What is a typical US size curve for knitwear?

A common starting point for US womenswear over five sizes is roughly XS 10%, S 20%, M 30%, L 25%, XL 15% — core sizes M and L carry about half the run. It's a planning default, not a rule: replace it with your own sales data as soon as you have a season of sell-through.

Does a factory MOQ apply per size?

At Kiwi Giyim, yes — the 250-piece minimum applies per colour and per size, because each size is knitted from its own machine programme. So one colourway across an XS–XL run is five separate 250-piece programmes. Use this planner to set the size ratio and see the total quantity once you are ordering above that per-size floor.

Can I change the size curve on a reorder?

Yes — and you should. The first run's curve is a forecast; the reorder's is data. Restocking a winner with a corrected size split (typically 65–80 days on a repeat programme) is exactly how small first runs are meant to work.
