what size is 38 in us

A European size 38 is usually a US women’s shoe size 7.5 and roughly a US men’s shoe size 6–6.5, depending on the brand and chart used.

Because your question is short, here are the two most common interpretations:

• EU 38 shoes → US size
  • Women: typically US 7.5.

* Men: often around US 6–6.5 in many conversion charts.

• “38” as US clothing size
  • In US menswear, “38” by itself can also mean a 38‑inch waist in pants or jeans.

If you tell me whether you mean shoes or clothes (and men’s or women’s), I can narrow this down more precisely.
