The number one complaint from international shoppers buying Chinese clothing is not quality or shipping — it is fit. A "large" from a Taobao seller can fit like a Western small, and the printed tag is often meaningless. The good news is that most listings include a detailed measurement chart. The bad news is that almost nobody reads it. Here is how to stop guessing and start ordering sizes that fit.
Why Chinese sizes run small
Chinese sizing is calibrated to a smaller average body frame, so a CN XL is frequently closer to a US medium or even small. The letter on the tag is a local convention, not a universal standard, and it varies wildly between sellers. The only number you can actually trust is the garment measurement in centimeters — which is why every serious shopper learns to read the chart instead of the label.
Standard size chart: tops
| CN size | Approx. US | Shoulder (cm) | Chest (cm) | Length (cm) |
|---|---|---|---|---|
| M | S | 43–45 | 100–104 | 66–68 |
| L | M | 45–47 | 106–110 | 68–70 |
| XL | L | 47–49 | 112–116 | 70–72 |
| 2XL | XL | 49–51 | 118–122 | 72–74 |
| 3XL | 2XL | 51–53 | 124–128 | 74–76 |
Standard size chart: bottoms
| CN size | Approx. US | Waist (cm) | Hip (cm) | Length (cm) |
|---|---|---|---|---|
| M | S / 30 | 72–76 | 96–100 | 98–100 |
| L | M / 32 | 78–82 | 102–106 | 100–102 |
| XL | L / 34 | 84–88 | 108–112 | 102–104 |
| 2XL | XL / 36 | 90–94 | 114–118 | 104–106 |
These tables are a starting point only — treat them as a rough map, because individual sellers deviate constantly. The chart inside the actual listing always wins.
How to read a listing's own size chart
- Find the measurement image — most listings include a diagram showing exactly where each measurement is taken.
- Note the tolerance. Chinese sellers often state a 1–3 cm margin of error; a 106 cm chest might arrive at 104 or 108.
- Compare to a garment you own, not to your body. Lay your best-fitting shirt flat and measure it the same way.
- Check the style. Oversized or "loose fit" pieces are meant to be much bigger than your body measurements.
- Read the reviews for "runs small" or "size up" comments from buyers with similar builds.
Measure a garment you already own
Body measurements tell you half the story; the other half is how a garment that fits you well actually measures when laid flat. Take your best-fitting shirt and measure it the same way a seller's chart does: chest from armpit to armpit (then double it), shoulder seam to seam, and length from the collar to the hem. Do the same for your favorite pair of pants — waist laid flat, then doubled, plus the inseam. These "garment reference numbers" are worth more than any generic table, because they are calibrated to your preference for fit, not to an average body.
Once you have both your body numbers and your garment reference numbers, reading any listing becomes mechanical: compare the seller's chart to the garment you love, and the decision makes itself. This is the single biggest upgrade over guessing from the letter size.
Notes for women's and unisex sizing
Women's Chinese clothing runs even smaller relative to Western sizing than men's does, and "one size" or "free size" items usually assume a petite frame — check the measurements carefully, since a free-size top may cap out around a 92 cm chest. Unisex pieces are typically cut from the men's block, so women often need to size down one from the unisex chart and still expect a roomier, boxier fit. When a listing is vague, ask the seller for the exact flat measurements before paying.
And do not ignore length. Chinese tops and pants are frequently cut shorter, so a tall shopper can hit every other measurement and still end up with sleeves or inseams that stop short. Always check the length column against your own height before finalizing.
When in doubt, size up
Too big can usually be tailored; too small usually cannot. If you are between sizes or the chart is ambiguous, order up — especially for shoulders and chest, which are the hardest to fix. Track each item's actual measurements in one place as you learn which sellers run true to size, and use the Oopbuy Spreadsheet method to log them. The planning tools at sheetquik.com are built for exactly this — keeping your measurements and each listing's chart side by side so the wrong-size gamble stops being a gamble.
