China Size Conversion Charts

LitBuy size charts help shoppers compare China marketplace sizing before ordering apparel or footwear from Taobao, Weidian and 1688 sellers. Size conversion is not exact because each seller, batch and product category can fit differently. The safest approach is to combine a conversion chart, seller measurements and warehouse QC measurement photos before shipping internationally.

This page explains how to use CN, US, UK and EU references without treating them as guarantees. A label marked XL can fit like a medium in another region. A shoe marked with a familiar EU size can still feel different because of last shape, insole length or material. Measurements are more reliable than labels.

How should buyers measure clothing?

Start with a garment that already fits well. Lay it flat and measure shoulder width, chest width, body length, sleeve length and waist where relevant. Compare those numbers with the seller chart, not only the size label. If the seller provides centimeters, use centimeters throughout the comparison to avoid rounding mistakes.

For hoodies, jackets and oversized streetwear, buyers should consider intended fit. A relaxed fit may require extra chest and shoulder room. A cropped fit may look correct even if body length is shorter than expected. If a product is expensive or hard to return, request warehouse measurement photos before shipping.

How should shoe sizes be checked?

Footwear should be checked by centimeter foot length or insole length whenever possible. US, UK, EU and CN conversions can differ across brands and styles. If the seller chart gives insole length, compare it with a shoe that already fits rather than relying only on a region label. For wide feet, narrow models or padded styles, allow extra room.

QC photos should show size labels, box labels and both shoes. If the shoe is high value or sizing-sensitive, ask for an insole measurement photo. This helps identify mislabeled pairs before the item leaves the warehouse.

What are common sizing mistakes?

Common mistakes include ordering by US size only, ignoring seller notes, assuming all batches fit the same, failing to check sleeve or shoulder measurements, and shipping before QC measurements arrive. Buyers also underestimate shrinkage, layering and the difference between slim, regular and oversized cuts.

A second mistake is comparing a body measurement directly with a flat garment measurement. A flat chest width is usually half of garment circumference. Buyers should compare garment-to-garment measurements when possible, not body-to-flat measurements without conversion.

How does sizing affect returns and shipping?

Sizing problems should be found before international shipping. Returning an item from the warehouse to a domestic seller is usually easier than returning it after it reaches another country. Once shipped internationally, return cost can exceed the item value. For this reason, measurement photos are one of the most useful QC requests for apparel and footwear.

Buyers should save the measurement evidence with the order record. If a dispute occurs, clear photos of the tape measure, size label and seller chart are more useful than a general statement that the item feels too small.

Common questions

Is a conversion chart enough?

No. Use conversion charts as a starting point, then confirm seller measurements and QC measurement photos.

Should buyers size up for China marketplace apparel?

Sometimes, but not always. The better method is to compare exact centimeter measurements with a garment that already fits.
