Size Converter: Turn Chinese and EU Sizes Into Yours Before the Parcel Leaves China

Checked · the PandaBuy Alternatives desk

Short answer

With an agent, a wrong size can only be swapped while the item is still in China; once the parcel ships, it's yours. That was true on PandaBuy and it's true at every agent now. Shoe listings mostly use EU sizes or foot length in millimetres ('260' = a 26 cm foot, about EU 41, US men's 8, UK 7 on a common trainer chart). Chinese clothing labels like 175/92A mean a wearer 175 cm tall with a 92 cm chest and regular build, which usually fits like a Western M. The three converters below cover shoes, clothing labels and fitted caps, and run in your browser.

A widely used men's trainer conversion. Brands differ by half a size; a seller's own chart in millimetres beats it.

Measure standing, heel to longest toe, in the evening when feet are largest. Then ask the agent for the insole length of the pair you bought; it's the single most reliable number, and most warehouses will measure it on request.

What 170/88A on a Weidian tag really means

The first number is height in centimetres; the second is chest girth on tops or waist girth on bottoms; the letter is build, from Y (slim) through A (regular) to B and C (fuller). Sellers then attach their own letter sizes, which often run a size smaller than Western ones:

Based on China's height/chest labelling; shops vary, and oversized streetwear often fits true to your usual size.

Caps: from a tape round your head to a fitted size

Calculated: cap size = head circumference in inches ÷ π.

Measure with a soft tape where the cap sits, about a finger's width above the ears. Fitted caps don't adjust, so between sizes take the larger. Snapbacks don't need this.

Measuring so the size is right first time

Converters get you close; measurements get you right. The routine that avoids most size problems on an agent haul:

  1. Measure a garment you like lying flat: chest (armpit to armpit), length and sleeve, in centimetres.
  2. Check the listing's convention: flat width or full chest? The full figure is about double.
  3. Choose by centimetres, allowing 1–2 cm for measuring differences.
  4. Ask the warehouse to measure when the item arrives. Most agents will, and some include it in QC.
  5. Decide before the parcel ships. PandaBuy's 4 photos rarely showed a tape measure; ask for one.

The clothes sheet and shoes sheet carry model notes on their tiles, and the QC guide explains what to look for in measurement photos.

Verdict: Pick by centimetres, confirm with a warehouse measurement, and only then pay for shipping.

Size questions

Do Chinese clothes run small?

Fitted pieces often do, by about one size against Western letters, so a seller's L may fit like your M. Oversized streetwear is the exception and often fits true to your usual size. A label like 175/92A tells you the height and chest it was cut for. Compare the seller's centimetre chart with a garment you own, allowing 1–2 cm.

What is EU 42 in US sizes?

On a common men's trainer chart, EU 42 is about US men's 8.5, US women's 10 and UK 7.5, for a foot of roughly 26.5 cm. Brands can differ by half a size, so a seller's chart in millimetres beats any general table. Measure your foot in the evening. When the pair reaches the warehouse, ask the agent for the insole length.

What does 175/92A mean?

It describes the body the garment was cut for: about 175 cm tall, a 92 cm chest, and a regular build shown by the letter A. Y means slim, while B and C are fuller. Sellers often label that size L, yet it usually fits like a Western men's M. On trousers, the second number is waist girth instead of chest. Go by the centimetres, not the letter.

A shoe listing says 265. What does that mean?

It's foot length in millimetres, so 265 means a 26.5 cm foot. Many shoe listings use this instead of EU sizes; on a common trainer chart, a 260 listing is about EU 41 or US men's 8. Measure standing, from heel to longest toe, ideally in the evening. Choose the listing that matches your measured length rather than your usual size.

How are fitted cap sizes calculated?

Take your head circumference in inches, divide it by π, and round to the nearest eighth. A 58.8 cm head, for example, gives a fitted size of 7 3/8. Measure with a soft tape about a finger's width above the ears, where the cap sits. Fitted caps don't adjust, so if you fall between two sizes, order the larger one.

Can I return a wrong size from an agent?

Only while the item is still in the agent's warehouse in China and the seller agrees to an exchange. Once the parcel ships, the size is yours to keep. PandaBuy's 4 photos rarely showed a tape measure, and that gap still matters at today's agents. Ask the warehouse to measure before you pay for shipping, and settle every size question then.

Does the converter store anything?

No. All three converters, for shoes, clothing labels and fitted caps, run entirely in your browser. The sizes, foot lengths and head measurements you type aren't sent anywhere or saved between visits, and no account is needed. You can check as many listings as you want without leaving a trace. Use it freely while comparing sizes before you order.
