CN 38 is a Chinese shoe size that usually fits a foot about 24–24.5 cm long and roughly corresponds to around a women’s US 6.5–7 (about EU 37–38, UK about 5–5.5), depending on brand.

What is CN 38 shoe size?

In the Chinese sizing system, CN 38 is a number that’s based on foot length in centimeters.

Most guides place CN 38 at around 24.0–24.5 cm foot length.

Typical conversions (can vary by brand and chart):

  • About US women’s 6.5–7
  • About US men’s 6–6.5
  • About EU 37–38
  • About UK 5–5.5

Because different brands (and even different guides online) sometimes list slightly different equivalents, it’s normal to see small variations like “US 6.5” vs “US 7” for the same CN 38.

Quick tips before you buy

  • Measure your foot length in cm (heel to longest toe) and compare to the seller’s own size chart, not just “CN 38 = US 7”.
  • If you’re between two sizes, going up half a size is usually safer, especially for closed shoes or sneakers.
  • Check reviews to see if that model runs small, large, or true to size, as this often matters more than the printed conversion.

TL;DR

CN 38 ≈ 24–24.5 cm foot length and is roughly equal to a women’s US 6.5–7 / EU 37–38 / UK 5–5.5, but always confirm with the specific brand’s size chart before ordering.
