Women's Dress and Shoe Size Converter: US, UK, EU, Japan and Korea

You found the perfect dress on a Korean site, or the heels of your dreams from an Italian brand, and then you hit the size menu. Is a 38 small or large? What on earth is a 55? Is a 240 a shoe or a phone number?

This free women's size converter turns any dress or shoe size into US, UK, EU, French, Italian, Japanese and Korean sizes in one tap, with body measurements so you can double-check before you buy.

Why your size changes from country to country

There's no single global sizing system. The US, the UK, mainland Europe, Italy, Japan and Korea each built their own over the last century, based on different measurements and different average body types. On top of that, many brands use "vanity sizing", labeling clothes a size smaller to make shoppers feel good. That's why you can be a 6 at one store and a 10 at another.

A converter gets you close. Your measurements get you the rest of the way. That's why the tool shows typical bust, waist and hip numbers next to every dress size.

Korean and Japanese sizes, decoded

Korean brands often use 44, 55, 66, 77 and 88. A 55 is roughly a small and a 66 a medium. The numbers come from an old standard based on height and bust, so each one covers about two US sizes. Japanese brands use odd numbers like 7, 9 and 11, where 9 is the classic medium. Asian brands also tend to cut shorter in the torso and sleeves, so if you're tall, check the length measurements too.

Women's shoe size chart

US	UK	EU	Japan / Korea	Foot length
5	3	35.5	220	22 cm
6	4	36.5	230	23 cm
7	5	37.5	240	24 cm
8	6	38.5	250	25 cm
9	7	40	260	26 cm
10	8	41	270	27 cm

Japan and Korea size shoes by foot length in millimeters, which is actually the most precise system. If you know your foot length, you know your Asian size.

How to measure your feet at home

1. Stand on a sheet of paper against a wall, heel touching the wall.
2. Mark the tip of your longest toe. It isn't always the big toe.
3. Measure from the wall to the mark in centimeters. Do both feet and use the longer one.
4. Measure in the evening. Feet swell a little during the day, and that's when your shoes need to feel good.

Heels are a different game. A pointed toe or a high arch can mean going half a size up. For more comfort tricks, read how to wear heels all night without the pain.

Smart tips for shopping international brands

• Always check the brand's own size chart for the exact item, especially for stretch versus woven fabrics.
• Read reviews for "runs small" or "runs big" before you order.
• Know your three numbers: bust, waist and hips. Our body shape calculator tells you how to measure and which cuts flatter you.
• Lingerie has its own system. Use the bra size calculator for bras.
