Chinese clothing sizes usually run smaller than US and EU sizes, so you cannot trust the letters on the tag. A Chinese “M” often fits more like a US “XS” or “S”, and larger sizes can jump even more. The only reliable way to convert Chinese sizes to US/EU is to work from measurements: get your (or your customer’s) bust, waist, hip, shoulder, and inseam in centimeters, match them to the supplier’s size chart, and then decide what US/EU size that measurement corresponds to. On marketplaces like DHgate, that means reading charts for each listing, often sizing up 1-2 US/EU sizes, and never assuming one brand’s “L” is the same as another.
China is a major source of apparel for US and EU markets, so sizing mistakes translate directly into returns and complaints. If you’re importing or dropshipping, a clean conversion process matters almost as much as the design and fabric.
Why Chinese Clothing Sizes Don’t Match US/EU Labels
Chinese sizing systems are built around local body measurements and proportions, not US or EU standards. Many Chinese suppliers cut garments for relatively shorter heights and smaller frames, which means the same “size letter” covers a different body.
That’s why you see broad patterns like:
- Chinese sizes commonly running 1-2 sizes smaller than US/EU equivalents.
- A Chinese “M” aligning with something closer to a US “XS” or “S” in many charts.
These are only patterns, not rules. One factory’s CN L might fit like a US S, another might be closer to a US M. Garment type matters too: streetwear hoodies can be boxy and oversized, while tailored dresses or slim-fit shirts can feel much tighter than the label suggests.
Plus-size and XXL+ categories are often limited in many Asian markets. That doesn’t mean they don’t exist; it means sizing jumps can be irregular and fewer suppliers cut for broader shoulders, larger busts, or fuller hips. For Western buyers, especially in the US, that’s where blind reliance on letters (XL, XXL, 3XL) creates the most dramatic misfits.
Practical Steps to Convert Chinese Sizes to US/EU Measurements
The safest way to shop or build size charts for your store is a simple measurement-first workflow.
Step 1: Get accurate body measurements in centimeters
For clothing sourced from Chinese suppliers, always work in centimeters. If you have measurements in inches, multiply by 2.54 or use a conversion tool such as the guide at Yijiansuan.
Key measurements:
- Bust/chest – fullest part, parallel to the floor.
- Waist – narrowest part of the torso.
- Hip – fullest part of the seat.
- Shoulder width – from shoulder point to shoulder point.
- Sleeve length – shoulder point to wrist.
- Inseam – crotch seam to ankle.
If you resell, build a simple intake form or reference chart that uses these measurements, not just S/M/L.
Step 2: Read the supplier’s Chinese size chart
On DHgate and similar marketplaces, many listings include a detailed size chart. You want a table that shows measurements for each size, usually in centimeters. If a listing only says “Asian size, runs small”, that’s a red flag for resellers.
Match your body measurements to:
- Bust/shoulder for tops and dresses.
- Waist/hip/inseam for pants and jeans.
Pick the size whose garment measurements are 2-6 cm larger than the body measurement at the main fit point (bust for tops/dresses, hip for tight bottoms). That allowance is your ease room; going smaller risks a tight or unwearable fit.
Step 3: Use a conversion pattern as a sanity check
Once you’ve picked a Chinese size from the chart, translate it to a rough US/EU size so customers understand what they’re buying.
Here’s an example reference pattern for adult tops from common charts:
| Chinese letter size | Typical garment bust (cm) | Rough US letter | Rough EU size* |
|---|---|---|---|
| CN S | ~84-88 | US XXS–XS | EU 32-34 |
| CN M | ~88-92 | US XS–S | EU 34-36 |
| CN L | ~92-96 | US S–M | EU 36-38 |
| CN XL | ~96-100 | US M–L | EU 38-40 |
| CN XXL | ~100-104 | US L–XL | EU 40-42 |
*EU sizes vary widely by brand; treat these as ballpark ranges, not guarantees.
This kind of table is editorial judgment based on patterns described in sources such as ChinaFit AI and Rep Tools. It’s only a starting point; always override it with the actual chart from your seller.
Step 4: Adjust for garment type
Tops and hoodies Use bust and shoulder first. If your bust is 90 cm and the chart says:
- CN M bust 88 cm
- CN L bust 92 cm
CN L is safer, especially if it’s a woven shirt without stretch. For oversized hoodies, you might intentionally jump to CN XL or XXL to match US streetwear expectations.
Pants and jeans Focus on waist, hip, and inseam. For a customer with 74 cm waist and 96 cm hips, you might choose:
- A size where waist is 76-78 cm and hips 98-100 cm.
Don’t assume “CN 28” or “CN L” equals a US numeric size. Denim fits can vary more than tops.
Dresses and jumpsuits Use bust, waist, and hip. If one area is significantly larger than the chart for your height, prioritize the largest point and plan for tailoring.
Step 5: Watch the problem zones: plus-size and “one size”
Plus-size / XXL+ Because plus-size ranges are often limited in Asian production, the grading (how sizes increase) can be uneven. A CN XXL might jump a lot from XL, or barely at all. Double-check:
- How much bust/hip increases between XL, XXL, 3XL.
- Whether the cut looks straight (unisex) or shaped (curvy).
If charts stop at measurements below your target customer’s size, don’t try to force a conversion; pick a different supplier.
“One size” or “free size” listings Treat “one size” as a fit warning, not a convenience. Read the actual garment measurements and set clear expectations: for example, “fits best for bust 82-94 cm” instead of pretending it’s a universal M/L.
Worked example: converting a CN top and jeans
Example 1: Women’s blouse Customer bust: 92 cm, waist: 76 cm.
Supplier chart:
- CN M – bust 88 cm, waist 70 cm
- CN L – bust 92 cm, waist 74 cm
- CN XL – bust 96 cm, waist 78 cm
CN L is exactly 92 cm at bust, leaving almost no ease. CN XL adds 4 cm of ease at bust and 2 cm at waist, which is more comfortable for a structured blouse. You’d likely list this as roughly US M (EU 38) with a note that it runs small compared to some Western brands.
Example 2: Men’s jeans Customer waist: 84 cm, hip: 100 cm, inseam: 79 cm.
Supplier chart:
- CN L – waist 82 cm, hip 98 cm, inseam 78 cm
- CN XL – waist 86 cm, hip 102 cm, inseam 80 cm
CN XL provides 2 cm ease at waist and hip and a close inseam. That’s the safer choice. You’d describe it as roughly US 32-33″ waist but keep the centimeter measurements visible for accuracy.
Applying Size Conversion When Sourcing Chinese Clothing on DHgate
If you’re using DHgate as your sourcing marketplace, the same sizing workflow applies — but you add seller selection and product testing on top.
Here’s how to apply it practically:
- Filter for listings with detailed size charts. When a DHgate product page shows a full chart with bust, waist, hip, length, and sometimes shoulder, it’s much easier to build accurate US/EU conversions.
- Compare charts across sellers. Two sellers might both label a hoodie “XL” but one cuts it like a US M and the other like a US L. Treat each listing as its own sizing system.
- Order samples before you commit. For any style you plan to stock or advertise heavily, buy at least 2-3 adjacent sizes (say CN L, XL, XXL), measure them yourself, and try them on fit models whose measurements you know. That’s a common best practice highlighted by importer guides such as DailyFulfill.
- Publish your own conversion charts. On your site or marketplace storefront, translate each DHgate supplier’s chart into a clear US/EU-facing table, using the kind of mapping shown earlier and your sample findings. Label them per product; don’t reuse one chart across brands.
If a DHgate listing has no chart, only generic text, or very limited XXL+ options for your target audience, that’s usually a sign to keep browsing. There are many Chinese suppliers and marketplaces; your job is to pair the right products with honest sizing information so your buyers aren’t guessing.
