Of the 691 items on our shelf, 47 carry a size chart. That is not a scraping failure. It is what the market looks like: a photograph, a price, a size letter, and nothing else.
So the normal case is that you are buying a garment with no measurements at all, and the fix is not a conversion table. It is a message.
Why the numbers are missing in the first place
A Yupoo album is a photo album, not a product page. The seller uploads shots of the item and, if you are lucky, a photographed size card among them. There is no field where measurements are supposed to live, so nothing complains when they are absent. How a Yupoo album is put together explains why so much of what you need sits outside the listing.
Where a chart does exist, it is usually an image — a card in Chinese, screenshotted, sometimes rotated, sometimes for a different item in the same batch. The 57 charts we hold were read out of images one at a time, and all 57 came from a single seller. Eight other sellers on our shelf publish none we could read.
The message that actually gets answered
Sellers and agents answer short, specific, single-item questions. They ignore essays. Send the item link, then the fields, then stop typing.
Ask for these, in centimetres, measured flat on the garment:
- Chest or waist, straight across, at the widest point of the body of the garment.
- Total length, from the highest point of the shoulder or the top of the waistband down.
- Shoulder, seam to seam, for anything with a set-in sleeve. Hip and hem opening for anything with legs.
- Sleeve, from shoulder seam to cuff, or rise and inseam for trousers.
- The size they measured. An answer with no size attached to it is not an answer.
Name the size you are asking about rather than asking for the whole grid. One size measured is worth more than five sizes quoted from a card the seller did not make.
If the item comes in more than one colourway or fabric, say which one. Batches of the same silhouette are not always cut identically, which is the whole reason batch language exists.
Reading the answer you get back
Three replies are common and only one of them is useful.
A set of numbers. Good. Note that they came from the seller's tape, on one garment, and that the sellers who do print charts routinely attach a stated 1 to 3 centimetre margin of error to their own manual measurements. Assume the same tolerance on a number typed into a chat window.
"Fits true to size" or "normal size, don't worry." This is not a measurement, and treating it as one is how people end up with a jacket they cannot close. True to what? The reference is unstated, and unstated references are the recurring failure in all rep sizing — the reason we refuse to compare numbers between sellers is written up on the methodology page.
"What is your height and weight?" This is the seller offering to size you from a body, which is the mapping their own charts use. It is a real answer, and it is a weak one. In the charts we hold, a body of 178cm and 60kg is mapped by the same seller to eight different size labels across different items. Take the recommendation, then ask for the flat measurement of the size they named.
What to do when nothing comes back
Some stores never reply, some are brokered through a middleman, and some are gated shut. That is not a sizing problem you can solve with a better question, and there is no honest workaround that involves borrowing a different seller's numbers for the same silhouette. Two sellers' "chest 63" are not known to describe the same thing, and we will not pretend otherwise.
What you can do instead:
- Measure a garment you already own that fits the way you want this one to fit, and hold those four numbers ready. They are the reference you will compare against whenever a number finally appears.
- Buy the item whose seller answers. Responsiveness before an order is the cheapest signal you will get about responsiveness after one, and it is one of the things worth weighing when you evaluate a seller yourself.
- Decide in advance which way you will guess. For a boxy overshirt, too big is wearable. For anything cut close, it is not.
The measurement that always exists
Even with no chart and no reply, one real measurement is still available to you, and it is the best one in the process: the QC photo.
Your agent buys the item, receives it in their warehouse and photographs it before it ships. You can ask for a tape laid across the chest or the waistband in that shot. That number comes off the actual object you are buying, not off a card, not off a chat message, and not off a garment from a different production run.
It is also the last point where the answer still matters. Reading QC photos covers what else to look for while you are there, and what is still fixable once a parcel lands covers how little is left afterwards.
Paste the listing into the link decoder before any of this, so the link you are asking about is one that still resolves. Asking a seller detailed questions about a dead album wastes the one exchange they were willing to have with you.
