Clothing Size Converter
Convert women's, men's, and kids' clothing sizes across US, UK, DE, FR, IT, JP, KR, and AU. Measure yourself or pick a known size. Data-insufficient systems (like CN) are shown honestly instead of hidden.
Measure → Size
How to measure yourself
Use a soft measuring tape (not a rigid ruler). Wear thin, close-fitting clothing or measure directly on skin for accuracy.
- 1
Chest / bust
Wrap the tape around the fullest part of your chest or bust, keeping it parallel to the floor. Don't pull tight — the tape should sit snugly, not compress.
- 2
Waist
Find your natural waistline (the narrowest point, usually just above the navel). Wrap the tape around it without sucking in.
- 3
Hip
Stand with feet together and wrap the tape around the fullest part of your hips/seat, roughly 20 cm below your waist.
- 4
Neck (for shirts)
Wrap the tape around the base of your neck where a collar would sit, then slip two fingers under the tape for breathing ease.
Measure loosely around the fullest part of your bust, tape parallel to the floor.

Why the same size fits differently across brands
"Vanity sizing" means brands label garments with smaller numbers than the body measurements would strictly imply, to make shoppers feel good about the size they're buying. The US women's size formula (chest in inches minus 28) is a nominal, historically-anchored number — it hasn't kept pace with how brands actually cut clothes today, so a US size 8 at one brand can measure very differently from a US size 8 at another.
This converter gives you standards-based reference numbers (Wikipedia-sourced formulas and tables), not brand-specific fits. Use it to get in the right neighborhood, then always check the specific brand's own size chart before buying — especially for fitted garments like dresses, blazers, or tailored trousers.
We also show systems marked "data insufficient — pending" (like most CN correspondences) instead of quietly hiding them. If a field is blank, it's because we couldn't verify a number against a real source — not because the size doesn't exist.
How this converter works
Each size system is anchored to a real body measurement in centimeters, then looked up by nearest match — the same approach used by our shoe and bra size converters.
- Women's tops/dresses are anchored on bust circumference; women's bottoms are anchored on waist circumference (same source table, different anchor column).
- Men's shirts use neck circumference (collar sizing); men's T-shirts/casual tops use chest circumference — these are two different systems, not one.
- Men's suit sizing (letter ↔ EU number) has no published body-measurement anchor, so it's shown as a reference chart only — not part of the measure-to-size calculator.
- Kids' sizing uses height in centimeters directly (EU size code = height in cm). US and UK codes vary meaningfully between sources — we show both cited sources side by side rather than averaging them into a false consensus.
- DE, FR, and IT are always shown as three separate columns. They differ by small constant offsets (roughly 2 cm apart) and merging them into one "EU" number would silently lose precision.
- Fields with no verifiable source data (mainland China's GB/T 1335 numeric correspondence, most men's and kids' JP/KR breakdowns, IT trouser sizing above waist 34in) are shown as "pending" rather than estimated.
Glossary
**Vanity sizing** — the practice of labeling clothes with smaller size numbers than strict body-measurement formulas would produce, common in US women's wear.
**Nominal size** — a size number that follows a naming convention (like the US women's formula) rather than a precise, universally-enforced measurement standard.
**Letter size (XS–XXL)** — an alpha size label used across many countries; the underlying cm measurements it maps to can still vary by brand and region.
**Collar size** — a men's shirt sizing system based on neck circumference in inches or centimeters, distinct from chest-based T-shirt sizing.
**Sister size logic** — not used for clothing the way it is for bra sizes; clothing letter sizes don't have a direct equivalent, which is why we show ranges rather than a single derived alternate size.

Frequently asked questions
- How do I convert US clothing size to EU size?
- There's no single "EU" clothing size — DE, FR, and IT sizing differ by small but real offsets (roughly 2 cm apart at the same nominal size). Using the Wikipedia-sourced formulas: DE = bust(cm)/2 − 6, FR = bust(cm)/2 − 4, IT = bust(cm)/2. So a US 8 (bust ~87cm) is roughly DE 38, FR 40, IT 44 — three different numbers, not one. Use the converter above to see all three side by side instead of guessing which "EU" a size chart means.
- What is a women's size chart from US to UK?
- UK sizes run 4 sizes ahead of US at the same body measurement: UK size = US size + 4 (e.g. US 8 = UK 12). This mirrors the Wikipedia letter/number table used in this converter: US 8/UK 12 both map to letter "M" with bust 86–89cm. Always double check against a specific brand's chart since UK high-street brands vary in cut.
- What is an international clothing size converter and how accurate is it?
- An international clothing size converter maps a size in one country's system (US, UK, EU, JP, KR, etc.) to the nearest equivalent in another, using standardized body-measurement tables. Accuracy is inherently limited: these standards are nominal reference points, and individual brands routinely deviate from them (this is sometimes called vanity sizing). Treat converted sizes as a starting point, then check the brand's specific chart for a garment you actually intend to buy.
- How does kids' clothing size by age work, and why do sources disagree?
- Kids' sizing is most reliably anchored to height in centimeters — the EU size code is literally the child's height in cm (e.g. EU code 104 ≈ 104cm tall). Age-based labels ("2T", "size 4", "4–5 years") vary significantly between brands and even between reference sources for the same market — we've seen two commonly cited sources disagree on whether a 92cm-tall toddler is US size "2" or "2T". When sources disagree, measure height and use the EU code as ground truth rather than trusting an age label alone.
- How do I convert a dress size between US, UK, and EU?
- Dress sizing generally follows the same women's bust/waist/hip correspondence table as tops, since most international standards don't publish a separate dress-specific chart. Enter your bust measurement (or the size you already own) in the Dress tab above to see it mapped across all systems. Keep in mind fitted dresses are especially sensitive to brand-specific cut, more so than tops.
- How do men's clothing sizes convert between US and international systems?
- It depends on the garment. Dress shirts use neck (collar) circumference — e.g. a 39cm neck is a men's Medium in the US/UK/EU/JP system used here. T-shirts and casual tops use chest circumference instead, on a completely separate scale. Trousers use waist circumference in inches, with EU sizes given as centimeter ranges. Check which measurement type applies to the garment you're converting before reading the chart.
- How do I find my shirt size using a size converter?
- For dress shirts, measure your neck circumference where a collar would sit (adding two fingers of ease), then match it against the collar size chart above — e.g. 39cm neck corresponds to UK/US 15.5in collar, roughly a Medium. For casual/T-shirts, measure chest circumference instead and use the chest-based chart, since collar and chest sizing don't share the same size labels.
- How do I convert pants/trouser sizes between countries?
- Enter your waist measurement (or a known US/UK waist-inch size) in the Bottom tab under Men. US and UK trouser sizes are usually identical (waist in inches), while EU sizes are given as centimeter ranges and Italian sizes follow their own separate numbering. Note that IT sizing data above a 34in (86cm) waist isn't available from our source and is marked pending rather than estimated.
- Why does this converter show some sizes as unavailable instead of guessing?
- Some correspondences — most notably mainland China's GB/T 1335 numeric sizing, and many JP/KR breakdowns for men's and kids' clothing — don't have a verifiable published conversion table we could confirm against a real source. Rather than making up a plausible-looking number, we mark these as "data insufficient — pending" so you know to check a brand-specific or region-specific chart instead of trusting an invented figure.
