Chinese Clothing Sizing Guide: Do Not Get It Wrong

Chinese sizes run differently. Here is how to measure yourself and convert sizes correctly when ordering from AllChinaBuy.

The number one reason international shoppers return clothing purchased from China is sizing. Not quality, not color accuracy, not shipping damage — sizing. Chinese clothing manufacturers design primarily for the domestic market, where average body dimensions differ significantly from Western populations. A size Large from a Chinese brand often fits like a Western Small or Medium. The "Asian fit" phenomenon is real: shorter sleeves, narrower shoulders, smaller armholes, and shorter torso lengths are standard. Understanding these differences before you order can save you weeks of waiting, return shipping fees, and the frustration of receiving an item you cannot wear. This guide teaches you how to measure yourself accurately, interpret Chinese size charts, and make adjustments for different garment types.

The Body Measurement Method

Before ordering anything, take your body measurements. Do not guess based on what size you wear at Zara or Uniqlo — those brands vanity-size their garments. You need a flexible measuring tape (the sewing kind, not a metal construction tape). For tops, measure: shoulder width (across the back from bone to bone), chest circumference (fullest part, keep tape level), sleeve length (shoulder bone to wrist bone), and overall length (base of neck to desired hem). For bottoms: waist circumference (at your natural waistline, not where your jeans sit), hip circumference (fullest part of buttocks), inseam (crotch to ankle along inside leg), and thigh circumference (fullest part of upper thigh). Write these down in both inches and centimeters since Chinese sellers use metric.

Reading Chinese Size Charts

Chinese size charts list measurements in centimeters, not inches. They typically show garment dimensions rather than body dimensions, which is a critical distinction. If a chart says "Chest 108cm," that means the garment measures 108cm around the chest when laid flat — not that it fits someone with a 108cm chest. For a comfortable fit, you want the garment measurement to exceed your body measurement by at least 4-8cm for woven fabrics and 2-4cm for stretch fabrics. When a seller lists only one measurement per size (like "Length 70cm"), they are showing the garment flat measurement for the primary dimension, and you may need to message them for a full chart.

Size Conversion Reference

While every brand varies, these conversion ranges provide a useful starting point for Chinese-to-Western size translation. For men: Chinese M roughly equals Western XS-S, Chinese L equals Western S-M, Chinese XL equals Western M-L, and Chinese XXL equals Western L-XL. For women: Chinese S equals Western XS, Chinese M equals Western XS-S, Chinese L equals Western S-M. The gap widens significantly at larger sizes. A Chinese 3XL may only fit like a Western XL. Oversized streetwear is an exception — many Chinese streetwear brands intentionally cut large, so a Chinese M in an oversized hoodie may fit like a Western L. Always check the product description for terms like "oversized," "loose fit," or "Asian sizing."

Garment-Specific Adjustments

Different clothing types require different sizing strategies. For hoodies and sweaters, if you want the oversized streetwear look, order your converted size. For a standard fit, size up once. For t-shirts, most Chinese reps run slim in the body and short in the sleeves. Size up once for a normal fit, twice for a relaxed fit. For jackets and outerwear, these typically require the most upsizing because they are designed for layering over thin clothing. Size up at least once, sometimes twice depending on the cut. For pants and shorts, the waist measurement is most critical. If the chart shows a 76cm waist for size M and your waist is 80cm, you need at least a size L, possibly XL depending on fabric stretch.

When to Ask the Seller

If a listing has no size chart, a vague chart, or confusing measurements, message the seller before ordering. Most Weidian sellers respond within 24 hours during business days. Ask specific questions: "What is the chest measurement for size L in centimeters?" or "Does this hoodie fit oversized or true to size?" Screenshots of your measurements help communicate clearly despite language barriers. If the seller is unresponsive or gives evasive answers, consider it a red flag and look for the item from another store. Good sellers take pride in accurate sizing information because it reduces returns and negative reviews.

What to Do If It Does Not Fit

Despite your best efforts, sizing mistakes happen. If an item arrives and does not fit, you have options. The ideal path is requesting a return through AllChinaBuy within the QC review window, but this only works if the item has not left the warehouse yet. For items already shipped internationally, returns to China are usually not economically viable due to shipping costs. In these cases, your options are reselling locally, tailoring the garment (feasible for pants and jackets but not for knitwear or sneakers), or accepting the loss as a learning experience. The best prevention is spending an extra five minutes measuring yourself before every order.

Summary

Chinese clothing sizing does not have to be a gamble. With accurate body measurements, careful chart reading, and a willingness to size up, you can achieve a hit rate well above 80%. The thirty minutes you spend measuring yourself and understanding these principles will save you hours of frustration, weeks of return logistics, and potentially hundreds of dollars in unsellable clothes. Make sizing the first skill you master as an international shopper, and everything else becomes easier.
