A Vinted listing shows the size label used in the seller's country, so the same dress can be tagged EU 38, UK 10 or US 6 depending on where the seller lives. Because Vinted is a cross-border secondhand marketplace, the size on a listing is not a unified international number — it is the same label the seller sees in their own wardrobe. To shop with confidence you have to translate that label into the system you already know, and the fastest way to do that is the Clothing Size Converter, which reads across women's and men's US, UK and EU charts in a single click.
Conversion is not the same as memorising a formula. A US 8 women's dress is a UK 12 and an EU 40. A US 38 men's jacket is a UK 38 and an EU 48. Each country standardised ready-to-wear sizing independently, so the numbers line up predictably for women's tops and dresses (UK = US + 4, EU = US + 32) and for men's chest sizes (EU = US/UK + 10), but the underlying body measurements are not perfectly equal between systems. Treat conversion as a starting point, then narrow your choice against the brand's own chart.
This guide walks through how to change clothing size on Vinted listings in three steps, the exact numbers to expect for women's and men's apparel, what the S/M/L letter labels really mean, and what to do beyond conversion to land on the right fit.
Why Vinted Sizes Vary by Seller Country
Vinted operates across most of Europe and North America, and each country's garment industry developed its own size convention. French, German, Spanish and Italian sellers tend to list in EU (continental) numbers, which is the same number printed inside Zara, Mango and H&M garments. UK sellers list in UK numbers, and US-based sellers list in US numbers. There is no automatic translation between these systems inside the Vinted app — the listing shows the seller's local label verbatim.
Two factors make this more confusing on Vinted than on a single-brand site. First, the same physical garment (a vintage Levi's trucker, a secondhand Cos blazer, a preloved Mango midi dress) can be listed by sellers in three different countries with three different numbers. Second, Vinted listings rarely include detailed measurements in the photo, and the seller's profile does not specify their country or unit system, so you have to recognise the system from the number alone. An EU 38 is recognisably continental, a UK 10 is recognisably British, and a US 6 is recognisably American — once you know which column to read.
How to Change Clothing Size on Vinted
Follow these three steps every time you meet an unfamiliar size on a Vinted listing.
- Open the Clothing Size Converter and choose women's or men's. Women's and men's apparel follow different rules and cannot be cross-read.
- Pick which system the number on the listing is written in: US, UK or EU. The number tells you the seller's country — a 38 in a men's jacket is the seller's chest inches if they are US or UK, and a continental number if they are EU.
- Type the size number into the box and read the equivalent US, UK and EU sizes plus the closest S/M/L letter, updated in real time. If the number you entered is not a standard size, the converter snaps to the nearest standard one and says so.
For a worked example, take a women's Vinted dress tagged EU 40. Set the input system to EU, enter 40, and the converter subtracts 32 to give you US 8, then adds 4 to the US to give you UK 12, with an approximate letter size of M. Reverse the input system to US and enter 8 to confirm: you get UK 12 and EU 40 from the same body.
Women's Size Conversions for Vinted
Women's tops and dresses on Vinted use the same numbering as the brand's own inside labels: a continental (EU) number on continental labels, a UK number on British labels, and a US number on American labels. The three columns line up predictably for these garments.
| US | UK | EU | Letter |
|---|---|---|---|
| 0–2 | 4–6 | 32–34 | XS |
| 4 | 8 | 36 | S |
| 6 | 10 | 38 | S |
| 8 | 12 | 40 | M |
| 10 | 14 | 42 | M |
| 12 | 16 | 44 | L |
| 14 | 18 | 46 | L |
| 16 | 20 | 48 | XL |
| 18 | 22 | 50 | XL |
The simple formulas are UK = US + 4 and EU = US + 32. A US 6 is a UK 10 and an EU 38; a US 10 is a UK 14 and an EU 42; a US 14 is a UK 18 and an EU 46. Use these to read across any Vinted listing the moment you see a number you do not recognise.
Men's Size Conversions for Vinted
Men's tops, jackets and suits on Vinted are sized by chest measurement in inches, and the US and UK use the same number. The EU number is 10 higher than the US/UK. A US/UK 40 chest is an EU 50, a US/UK 38 is an EU 48, and a US/UK 44 is an EU 54.
| US / UK (chest in) | EU | Letter |
|---|---|---|
| 34 | 44 | S |
| 36 | 46 | S |
| 38 | 48 | M |
| 40 | 50 | M |
| 42 | 52 | L |
| 44 | 54 | L |
| 46 | 56 | XL |
| 48 | 58 | XL |
These conversions apply to shirts, blazers, knitwear and outerwear. Men's bottoms (jeans and trousers) use a separate system based on waist inches in the US and UK and a different continental number. For jeans on Vinted, compare the waist measurement in inches directly against your own.
Reading Letter Sizes (S/M/L) on Vinted
Letter sizes appear on Vinted listings alongside the numeric label, especially from sellers listing casual or fast-fashion brands. Letters are the least standardised part of any conversion. As a rough guide, women's S is about US 4 to 6 (EU 36 to 38), M is US 8 to 10 (EU 40 to 42), and L is US 12 to 14 (EU 44 to 46). For men's, S is a 34 to 36 chest, M is 38 to 40, and L is 42 to 44.
Two brands can cut a medium to different bodies, and vanity sizing has shifted numbers over time within the same brand. Treat the letter shown on the Vinted listing as a quick filter, then read the numeric column through the converter and cross-check the brand's own chart before committing. The converter shows you the closest letter next to the numeric result so you can sanity-check the seller's label.
Beyond Conversion: Fit Tips for Vinted Shoppers
A converted size gets you to the right neighbourhood, not the right door. Three quick checks shrink the risk on every secondhand buy.
- Ask for measurements. Vinted lets you message the seller before paying. Ask for the garment laid flat: pit-to-pit for tops and jackets, waist for bottoms, and length top-to-bottom. A 2 cm difference changes fit dramatically on a fitted blouse.
- Match the brand to its home system. If the listing says Mango, Zara, H&M, COS, Massimo Dutti or Sézane, the number is an EU continental size. If it says Marks & Spencer, Next or Boden, the number is UK. If it says J.Crew, Madewell or Levi's, the number is US.
- Read the photos and fabric notes. Stretch fabrics (jersey, elastane blends) forgive a smaller converted size, while structured fabrics (wool, linen, cotton poplin) need the converted size or one up. A "runs small" note from the seller is worth more than any chart.
