Sizing is the most common reason a good find becomes a disappointment. The cause is not usually a bad listing; it is a label difference. Asian sizing runs smaller than US and EU sizing, often by one to two full sizes, and agent pages rarely shout about it because the label simply prints what the factory printed.
This guide explains how to convert between the two worlds without guesswork, and it leans on one habit: measure a garment you already own and trust, then compare those numbers with the chart rather than trusting a letter on a tag.
Why the letters lie
An XL on a Chinese-market hoodie may correspond to a chest circumference closer to a US medium. The label reflects the local size run, not the international one. Treat every letter as a rough bucket and every number as the truth.
Shoes are similar but a little more forgiving. A US 9 is roughly an EU 42.5 and about a 27 cm foot length in most of these listings, and half-size differences matter more on narrow silhouettes than on chunky ones.
Measure a garment you already like
Take a hoodie or tee that fits the way you want, lay it flat, and measure three things: chest circumference from pit to pit and doubled, body length from the high point of the shoulder to the hem, and shoulder width across the back. Write those numbers down. They are your personal size chart and they beat every label on the internet.
For trousers and jeans, measure waist, rise and inseam on a pair you like. For anything with a cuff, add the sleeve length. It takes five minutes and it eliminates most return shipping.
Read the chart in the QC set
Many finds include a measurement note or a chart in the QC photos. Compare it against your personal numbers, not against a size letter. If the chart is missing, the warehouse can often measure on request before you approve shipping.
Watch for notes that explain stretch, shrinkage or a relaxed fit. A garment described as oversized is usually designed to sit loose, so the number to match is your chest measurement plus a comfortable margin rather than an exact figure.
When to size up, and when not to
Size up on cotton that will shrink, on anything you intend to layer over another garment, and on fleece that packs down. Do not size up on technical shells where the cut is already generous, or on knitwear that is meant to sit close.
For shoes, size up a half step if you wear thick socks, and check the QC photos for the insole length if the listing offers it. If a silhouette is known to run narrow, half a size up is usually the safer call.
Reading Kakobuy size guide: how to read Asian sizing before you order well begins with the four things a spreadsheet row can and cannot tell you. It can tell you the platform the item came from, a reference price, and whether a quality-control photo set exists. It cannot tell you how the current batch fits, how heavy the parcel will actually be once packed, or whether the seller will still hold stock next week. Treat every row as a starting point and verify the rest as you go.
Price on a spreadsheet is a reference, not a quote. The same product family typically sells in several batches between the cheapest and the most expensive entry, and the gap is almost never random. Higher batches usually mean better fabric weight, cleaner stitching and a more accurate silhouette. If a listing is dramatically cheaper than its neighbours, assume a thinner material or a simplified construction until the QC photos prove otherwise.
Sizing deserves its own pass. Asian sizing runs smaller than US and EU sizes, often by one to two full sizes, and the label on the tag reflects the local size run rather than the international one. Before you order, measure a garment you already own across the chest, the body length and the shoulder, write the numbers down, and compare them with the measurement note in the QC set. Numbers beat letters every time.
Quality control is where the agent model earns its keep. After the warehouse receives your item, it photographs the goods against a plain background and posts the set to your order. That set is your last cheap moment to catch a defect: a domestic return inside China costs far less than discovering the same problem once the parcel has already crossed a border. Open every photo, zoom in, and compare it with what you expected.
Shipping is the cost that surprises people most. The first kilogram of any parcel dominates the bill, which means a two-kilogram parcel and a four-kilogram parcel to the same country often differ by far less than buyers assume. The practical consequence is simple: consolidate. Adding an item to an existing parcel is cheaper than starting a new one, and removing shoeboxes trims volumetric weight before the warehouse weighs the finished parcel.
