How to measure bust
Wrap a tape measure around the fullest part of your bust, keeping it parallel to the floor. Don't pull tight, leave a finger's width of ease. Measure in centimetres.
How to measure waist
Measure around your natural waistline, the narrowest part of your torso, usually about 2–3 cm above your belly button. Stand relaxed, don't suck in.
How to convert clothing sizes
Three steps. Works for any international sizing system.
- 01
Select gender and category
Men's and women's sizing use completely different scales. Tops and bottoms also differ: a women's M top doesn't guarantee a women's M bottom fits.
- 02
Choose your known size system and select your size
Pick US, UK, EU, or Asia as your starting point, then tap your size. The converter shows all four equivalents instantly. You can also tap any row in the chart to load that size.
- 03
Check the measurement in cm
Each result includes the corresponding bust/chest or waist measurement in centimetres. If you're between sizes, measure yourself and use the cm range to decide which size to order.
When you need this
Ordering from international fashion sites
A US women's M is a UK 12-14 and EU 40-42. On sites like ASOS (UK), Zara (EU), or Shein (Asia), the size labels mean different things. This converter prevents the wrong order.
Buying gifts for someone abroad
If you know someone wears a US men's L, you can convert to EU 52-54 and order from a European brand without guessing or asking.
Shopping Asian fashion brands
Asian sizing (especially from Chinese and Korean brands) runs smaller than Western sizing. A Western M often maps to an Asian XL or XXL. The chart makes this explicit.
Comparing sizes across brands
H&M, Zara, and Uniqlo all size differently even within the same country. The cm measurement column is the most reliable anchor when brands don't agree.
Measure, then compare: how to use the chart
Letter sizes such as M and L mean different things in different countries and brands, so the measurements in the chart are the reliable part. Measure with a soft tape over light clothing, keeping it level and snug but not tight. Chest or bust goes round the fullest part, under the arms. Waist goes round your natural waist, usually just above the belly button. Hips go round the widest part of the seat.
Match your measurement to the chart's range, then read across to the size system you're buying in. If you fall between sizes, choose by the measurement that matters most for the garment: chest for shirts and jackets, waist for trousers and skirts, hips for fitted dresses and jeans.
Why sizes still vary between brands
There's no single international clothing standard that brands follow. Many fashion labels have drifted towards labelling larger measurements with smaller sizes over the years, often called vanity sizing, and fast-fashion, sportswear and luxury brands each cut differently. Asian sizing, used by many brands selling in Japan, Korea and China, typically runs one or two sizes smaller than US labels for the same letter.
- Always check the specific brand's size chart before ordering, and use this one to translate between systems.
- Read the fit description: slim, regular and relaxed cuts of the same size can differ by several centimetres.
- For online orders, check the return policy before you buy a size you're unsure of.
