How it works
The conversion follows the common retail comparison chart, not a single international standard, because there is none for dress size numbers. Each row moves up one size in every system at the same time: US 0, 2, 4 and so on match UK 4, 6, 8, France and Spain 32, 34, 36, Germany and the Netherlands 30, 32, 34, and Italy 36, 38, 40. In formula form, UK = US + 4, France = US + 32, Germany = US + 30 and Italy = US + 36. Australian sizes use the same numbers as UK sizes on most retail charts.
Letter sizes cover two number sizes each on the same chart: XXS is US 0, XS is US 2 to 4, S is US 6 to 8, M is US 10 to 12, L is US 14 to 16, XL is US 18 to 20 and XXL is US 22 to 24.
Japanese sizes come from the Japanese standard JIS L 4005, which labels women's sizes 3, 5, 7 and so on by bust, from 74 cm upwards in steps of 3 or 4 cm. The converter matches each row by bust, using the traditional British rule that bust in inches = UK size + 24, and picks the Japanese size with the nearest bust within 3 cm. Japanese steps are smaller than UK steps, so sizes such as 9, 13 and 21 sit between two rows.
To find your size from measurements, the tool compares each measurement with the body measurements in the US standard ASTM D5585-11 for misses sizes 0 to 20 (straight figure). For each one it picks the smallest size whose chart measurement is at least yours. For a dress it suggests the largest of those sizes, so the garment fits your fullest part.
What it cannot tell you
- Sizes are not the same from brand to brand. Two shops can label the same garment a different size, and many brands make their sizes larger over time. Always check the brand's own size chart.
- The measurement table is the 2011 version of ASTM D5585, which ASTM withdrew in 2020. UK, European and Japanese brands measure their sizes differently, so a measurement result is a US size first and the other systems are the usual equivalents, not a guarantee.
- Your shape matters as much as the numbers. Someone with a fuller bust or hips than the chart may need different sizes for tops and bottoms, or a petite, tall or curvy fit.
- Jeans are left out. Jeans sizes are often a waist measurement in inches, but conversion charts disagree too much to give one reliable answer.

Common questions
A UK size 12 is usually a US size 8 on standard comparison charts. In Europe it is usually a 40 in France and Spain, a 38 in Germany and a 44 in Italy, and in Australia it is also a 12. Brands vary, so check the brand's own size chart.
To convert a US dress size to a UK size, add 4. A US 6 is usually a UK 10 and a US 10 is usually a UK 14. This is the common retail rule rather than a standard, and some brands differ by a size.
A women's medium is usually a US 10 to 12 or a UK 14 to 16 on general comparison charts. Letter sizes vary more between brands than number sizes do, so some brands call a US 8 a medium. Check the measurements on the brand's chart.
Australian and UK women's clothing sizes usually use the same numbers, so a UK 10 is normally an AU 10. Some people find that individual Australian brands fit a little differently, so check each brand's chart.
To measure for clothing size, use a soft tape held level and snug but not tight. Measure the bust around the fullest part, the waist around the narrowest part of your torso, and the hips around the fullest part of your bottom. Measure over light underwear, not over clothes.
