Introduction
We have all been there. You find the perfect streetwear hoodie or a stunning vintage-style dress on a Chinese marketplace. The photos are incredible, the price is unbeatable, and you eagerly hit “Buy.” But when the package finally arrives weeks later, excitement turns to confusion. You ordered a “Large,” yet the garment that emerged from the bag looks like it was sized for a pre-teen. You try to squeeze into it, but the sleeves stop at your forearms and the shoulders feel like a straitjacket.
This is the “Global Shopping Challenge”—a rite of passage for almost every Western shopper dipping their toes into the world of direct-from-China e-commerce.
Understanding the “Asian Fit”: The root of this issue isn’t deceptive marketing; it is anthropometry. “Asian Fit” is structured around the average East Asian body type. It typically features narrower shoulders, higher armholes, shorter sleeve lengths, and a slimmer torso cut compared to the standard American “Boxy” fit.
To navigate this marketplace successfully, you need more than just a lucky guess. This guide is designed to be your definitive manual for bridging that gap. We will move beyond simple T-shirts to cover the “Big Four” essential categories: Clothing (Tops), Pants, Shoes, and Belts.
Navigating these numbers doesn’t have to be a gamble. Whether you are looking for a detailed mens Chinese size to us conversion chart to buy a suit, or simply figuring out how to convert Chinese clothing sizes to US sizes for a casual haul, accuracy is key.
A Note on Accuracy (EEAT): To ensure reliability, our conversion data is derived from the Standardization Administration of China (GB/T standards) and cross-referenced with major US apparel industry sizing charts.
The Fundamentals: Measuring for Success
Before you even click on a product link, you need to recalibrate how you think about size. In the US, “Vanity Sizing” often shifts numbers to flatter the ego. In China, sizing is strictly mathematical. To win at this game, you must become a stickler for precision.
Metric is King: Abandon the Inch
The first rule of Chinese size to US size conversion is to stop thinking in inches. The entire Chinese garment industry operates on the Metric system. Flip your tape measure over to the centimeter (cm) side. It is more precise and aligns directly with every size chart you will encounter on Taobao, Weidian, or Tmall.
The “Chi” (尺) Factor: The Secret Unit
If you have ever browsed pants on a Chinese marketplace and seen sizes like “2尺2,” you have encountered the Chi (尺). This is a traditional Chinese unit of length still widely used in domestic manufacturing.
💡 Knowledge Point: Chi Conversion
- ✅ 1 Chi (尺) ≈ 33.33 cm
- ✅ 1 Chi (尺) ≈ 13.12 inches
Example: A “2尺4” waist is roughly 80cm (31.5 inches).
How to Measure Yourself (Step-by-Step)
- 1. Chest (The Anchor for Tops): Wrap the tape measure under your armpits and around the fullest part of your chest. If the garment’s chest measurement isn’t at least 2-4cm larger than your body, it will be skin-tight.
- 2. Shoulder Width (The “Make or Break” Stat): Measure from the outer edge of one shoulder bone across your back to the other. This is critical for Asian fit.
- 3. Waist: Measure your Pant Waist (where you actually wear your pants, roughly 2-3cm below the navel) rather than your natural waist for most trousers.
- 4. Foot Length: Place your heel against a wall and measure to the tip of your longest toe in millimeters.

Category 1: Clothing & Tops
Unlike the US system of “S, M, L,” the Chinese system uses strict anthropometric codes. Learning to read the GB/T standard code (like 170/92A) is your superpower.
170
Recommended Height (cm)
92
Chest Circumference (cm)
A
Body Type (Standard)
Women’s Tops Conversion
| US Size (Numeric) | US Alpha | Chinese Size | Label Code |
|---|---|---|---|
| 0 – 2 | XS | S | 155/80A |
| 4 – 6 | S | M | 160/84A |
| 8 – 10 | M | L | 165/88A |
| 12 – 14 | L | XL | 170/92A |
| 16 | XL | XXL (2XL) | 175/96A |
Caution: For Plus size China to US items, a standard Chinese 3XL often only equals a US Large/XL. Look for specialized “Large Size” (大码) stores.
Men’s Tops: The “Shoulder Gap”
Western men’s fashion typically accommodates broad shoulders (V-taper). Chinese sizing assumes a more linear frame. This creates the “Shoulder Gap.”
The “2-Up” Heuristic
As a general starting point for men:
- US Small ➔ Asian Large
- US Medium ➔ Asian XL
- US Large ➔ Asian XXL
Pro Advice: Always prioritize your Shoulder Measurement. If the chart’s shoulder width is smaller than yours, do not buy it. You cannot tailor shoulders wider.
Category 2: Pants & Bottoms
Buying pants requires mastering three variables: the traditional “Chi” unit, the silhouette difference, and the inseam gap.
Chi (尺) to CM/Inch Cheat Sheet
Many domestic sellers still use the traditional Chi unit. Save this table:
| Chi (尺) | Waist (CM) | Waist (Inch) | Approx. US Size |
|---|---|---|---|
| 1尺9 | 63.3 cm | ~25″ | XS / 25 |
| 2尺0 | 66.6 cm | ~26″ | S / 26 |
| 2尺1 | 70.0 cm | ~27.5″ | S-M / 28 |
| 2尺2 | 73.3 cm | ~29″ | M / 29 |
| 2尺4 | 80.0 cm | ~31.5″ | L / 31-32 |
| 2尺6 | 86.6 cm | ~34″ | XL / 34 |
| 2尺8 | 93.3 cm | ~36.5″ | XXL / 36 |
The Hip & Inseam Issue
US pants are often cut with a curvier Hip-to-Waist ratio. Chinese pants are often straighter.
Pro Tip: If you have a curvy figure (hourglass/pear), do not size by waist. Size by your hip measurement. It is easier to tailor a waist gap than to create fabric for tight hips.
Also, watch the inseam. Standard Chinese inseams are often 29-30 inches. If you are over 6’0″, look for “Extended Length” (加长版).
Category 3: Shoes
Chinese footwear follows the Mondopoint (mm) system. It is strictly linear and logical.
- 👞 Size 250 (25) = Fits a foot length of 250mm.
- 👞 Size 265 (26.5) = Fits a foot length of 265mm.
Men’s & Women’s Quick Reference
Common question: “What is size 40 in chinese shoe size to us?”. For men, it is approx US 7.5. For women, standard Chinese shoes are Width B. If you have wide feet (D), size up by 0.5 to 1 full size.
| CN Size | Foot Length (mm) | Men’s US Approx | Women’s US Approx |
|---|---|---|---|
| 36 | 230 | – | 6 |
| 37 | 235 | – | 6.5 |
| 39 | 245 | 6.5 | 8.5 |
| 40 | 250 | 7.5 | 9 |
| 42 | 260 | 8.5 – 9 | 11 |
| 44 | 270 | 10.5 | – |
| 46 | 280 | 12 | – |

Category 4: Belts
Belts in China are sold by Total Length (buckle to tip), not by pant size. If you buy a “110cm belt” thinking it fits a 110cm waist, it will be too small.
📏 The Golden Calculation
Waist Size (cm) + 20cm = Ideal Belt Length
Example: If you wear size 34 pants (87cm waist), you need: 87 + 20 = 107. Buy the 110cm belt.
