EU vs US sizing for yoga wear: how to get fit right

Updated 24 October 2026 · WORLUXFIT sourcing team

An “M” is not the same M in Xiamen and in Los Angeles. Production made to the wrong size system is the single most expensive mistake in a first order — and it is avoidable with three measurements and one clear spec sheet.

The short answer

  • Asian sizes run about one size smaller than US sizes for the same label.
  • Anchor everything to bust, waist and hip in centimetres — not to S/M/L.
  • For leggings, inseam and rise matter as much as the waist.
  • Ask for a graded size set in your market’s sizes, not a translated label.
  • Test fit on a body, not on a hanger — a 2 cm difference at the waist is a return.

Why an Asian M is not a US M

Size labels are convention, not measurement. A Chinese M is typically built for a bust around 84–86 cm; a US M is built for roughly 89–92 cm. Put the same label on both and you create a size run that fits nobody.

XXL44121698–10280–84106–110

These ranges describe our EU blocks. If your market expects a different grading, the pattern is re-graded to your chart — that is a normal request, not a special favour.

The three measurements that decide fit

  1. Bust — around the fullest point, arms down, tape level.
  2. Waist — the natural crease, not where the waistband sits.
  3. Hip — the widest point, usually 18–22 cm below the waist.

For leggings add two more: rise (crotch seam to waistband) and inseam. A 68 cm inseam suits a 165 cm body; a 71–73 cm inseam is a tall fit. Getting inseam wrong produces the “flooded” look that photographs badly and returns fast.

How to write a size spec a factory can make

Fit intentCompressive, high waist, squat-proof

Fit testing before bulk

Put the sample on at least three body shapes in your target size, not one. Ask each tester to squat, sit and walk for two minutes, then check four points: waistband roll-down, crotch drop, knee bagging, and show-through at full stretch.

Note the fixes as changes to the pattern — a 1 cm rise increase or a 2 cm waistband elastic upgrade — rather than “make it tighter”. Vague feedback produces a second sample round, which costs two weeks.

The grading question

If you plan to sell XS–XXL, ask for a graded set, not a scaled copy. Grading rules differ: waist rises more slowly than hip across sizes, and sleeves lengthen. A factory that “just enlarges” every point produces an XXL with a waistband too large for the body it is meant to fit.

Questions buyers ask

Can you just relabel an Asian size M as a US S?

Sometimes, and that is exactly what “Asian sizes run one smaller” means in practice. Check the body measurements against the table above rather than trusting the relabel.

What tolerance is acceptable on a waistband?

±0.5 cm relaxed, measured flat after two hours of rest. More than that and the same style fits differently across colours.

Do you grade to our chart or yours?

Yours. Send the chart with your size range and we re-grade the pattern before sampling — no extra cost on an existing block.

How long does a fit revision add?

Three to five days per round, plus courier. One round is normal; two usually means the original brief was unclear.

See our full size and fabric guide or send your size chart with your enquiry and we will confirm the grading before sampling.
