How to measure yourself

Use a soft tape measure over thin clothes or underwear. Keep it level and snug but not tight, and breathe out normally.

Bust: round the fullest part of the chest, under the arms and across the shoulder blades.
Chest (men): round the fullest part, under the arms, with your arms down.
Neck: round the base of the neck, where a shirt collar sits, with one finger under the tape.
Waist: round the narrowest part, usually just above the belly button. For men’s trousers, measure where you wear your trousers.
Hips: round the fullest part of the bottom, feet together.
Inside leg: from the crotch down the inside of the leg to the floor, without shoes.
Children: height without shoes, standing straight against a wall.

Size charts vary by brand. Every chart on this page is a typical one, as commonly published. Always check the brand’s own size chart before you buy, and compare your measurements, not just the label.

The formula

your size = the smallest chart size whose typical measurement + tolerance is at least yours
several measurements: take the largest size any of them needs
women: UK = US + 4 · EU = US + 32 · France = EU + 2 · Italy = EU + 4 · Japan = US + 3 · Australia = UK
men’s jackets: US/UK = chest in inches · EU = chest + 10 · Australia = chest in cm
men’s shirts: collar cm = collar inches × 2.54, rounded
men’s trousers: US/UK = waist in inches · EU = waist + 16 · Japan = waist in cm
children: EU = height in cm · Japan and China = height to the nearest 10 cm

A size label is just a row on a chart. Converting a size means finding its row and reading across to the other systems. Finding your size from measurements means finding the first row that is big enough for you. The tolerance lets a measurement be a little over the chart and still count: the default is 1 cm, for a snug fit.

Worked example

Converting US 6 in women’s dresses and tops:

UK: 6 + 4 = 10. Australia uses the UK number: 10.
EU: 6 + 32 = 38. France: 38 + 2 = 40. Italy: 38 + 4 = 42.
Japan: 6 + 3 = 9. Letter size: S (S covers US 4 and 6).
A typical US 6 is made for a bust of 88 cm, waist 70 cm and hips 95 cm, so China (height/bust) is 160/88A.

Finding a size from a bust of 89 cm, waist 71 cm and hips 98 cm, with 1 cm tolerance:

Bust: 89 ≤ 88 + 1, so US 6 is big enough.
Waist: 71 ≤ 70 + 1, so US 6.
Hips: 98 is more than 95 + 1 (US 6) but 98 ≤ 97 + 1, so US 8.
The largest is US 8 (UK 12, EU 40) for a dress. For a top, the bust decides: US 6.

Notes on each system

EU: Germany, the Netherlands, Austria and the Nordic countries use the plain EU numbers. France, Spain, Portugal and Belgium are usually 2 higher for women, and Italy 4 higher.
UK and Australia: women’s sizes go up in twos from 4. Australia and New Zealand usually follow UK numbers for women.
Japan: women’s sizes go up in odd numbers (5, 7, 9, 11). Letter sizes often run one size smaller than US letters, and LL or 3L stand for XL and XXL.
China: labels such as 160/84A give height and bust (or chest, or waist for trousers) in cm, and a letter for body shape. They come from the Chinese national sizing system; the rows shown here are typical matches.
Men’s shirts: the collar is measured in inches in the US and UK, and in cm almost everywhere else. Sleeve length is a separate number, often 32–35 in (81–89 cm).
Men’s trousers: often written as W32 L32: waist 32 in and leg (inside leg) 32 in. Short is about 30 in, Regular 32 in and Long 34 in.
EN 13402: the European standard (also published by ISO) for labelling clothes describes how to show body measurements in cm on a label. It does not give one size chart that all brands follow.

Every chart here is typical, built from commonly published retailer and size-guide charts, not an official standard. Brands and countries differ, often by a whole size, and vanity sizing makes labels drift over time. Check the brand’s own chart before you buy. Checked 19 October 2026.

Common questions

What is a US size 6 in UK and EU sizes?

On a typical women’s chart, US 6 is UK 10, EU 38 (Germany and the Netherlands), France 40, Italy 42, Japan 9 and Australia 10, which is a small (S). Brands differ, so check the brand’s own chart before you buy.

How do I convert UK dress sizes to US sizes?

Take 4 off the UK size: UK 10 is US 6, UK 12 is US 8 and UK 14 is US 10. For EU (German) sizes take 32 off the EU size to get the US size: EU 40 is US 8. French sizes are 2 more than EU and Italian sizes 4 more.

What size am I from my measurements?

Measure your bust, waist and hips, then find the smallest size whose typical measurements are at least yours. If they point to different sizes, dresses and trousers go by the largest measurement and tops by the bust. Type them in with “My measurements” to see your size in every system.

How do men’s suit sizes work?

In the US and UK the jacket size is your chest in inches, such as 40. Italian and other European sizes add 10, so a 40 is an EU 50. Australian suits are usually labelled by chest in cm, so a 40 is about a 102. Short, regular and long (S, R, L) refer to your height.

Are Asian clothing sizes smaller?

Often yes. Letter sizes in Japan and China tend to run about one size smaller, so a US M is often a Japanese L. Chinese labels such as 165/88A give the height and bust or chest in cm, which is the most reliable thing to compare. Check the measurements on the brand’s chart.

Is there an official international clothing size chart?

No single chart is used by every brand. The European standard EN 13402 (also an ISO standard) describes how to label clothes with body measurements in cm, but brands still choose their own sizes. The charts here are typical, commonly published ones, so always check the brand’s own chart.
