Chinese size chart to US baby clothes
Chinese baby clothes are usually labeled by height in centimeters. The height number is more useful than age because babies grow at different speeds.
Quick answer: Chinese baby size 66 is often around US 3-6 months, 73 is around 6-9 months, 80 is around 12 months and 90 is around 18-24 months.
01 /Examples and fit notes
Taobao baby label
A listing marked 80 is usually designed for a baby around 75-85 cm tall, not exactly every 12-month-old baby.
Fit note
Check garment length, chest and sleeve length when buying coats or sleepwear.
Important note
Baby clothing varies by brand, diaper room and garment type.
Note 2
Use child height in centimeters as the first check, then compare the seller chart.
02 /How to use this lookup
This page answers one specific size search intent. For the best fit, start with the linked main converter and use the centimeter measurements on the Chinese chart whenever they are available.
Marketplace labels are useful shortcuts, but brand charts, garment type, fabric stretch and body measurements can change the final fit. Treat the lookup as a nearest match, not a guaranteed size.
03 /Size conversion context
Chinese size labels are practical lookup shortcuts, not universal brand guarantees. A CN shoe label, clothing size, bra code or Taobao chart row can vary by seller, product category, last shape, fabric stretch and whether the chart shows body measurements or garment measurements.
When possible, use the centimeter value first: foot length for shoes, bust/waist/hip for clothing, under-bust and cup difference for bras, and the specific Taobao chart row for marketplace listings. Then use the converter result as the nearest US, UK or EU match.
