When to use it

Use this converter when buying clothes from another country, ordering from an international online shop, or buying a gift when you only know someone’s size in one system. It covers women’s clothing and men’s suits and jackets, shirts, and trousers and jeans, across letter, US, UK, EU, Italian, Japanese and Australian sizes.

How to use it

  1. Choose the Clothing: Women’s clothing, Men’s suits and jackets, Men’s shirts or Men’s trousers and jeans.
  2. Under I know my size in, choose the system you know, such as US or UK.
  3. Pick your Size from the list.
  4. Read the Equivalent sizes in every system.
  5. Check the full chart below. Your size is highlighted, and men’s charts include body measurements in centimeters.

Worked example

You wear a women’s US 10 and want to order a dress from a British shop. Choose Women’s clothing, US and size 10. The equivalent sizes are UK 14, EU 40, Italy 46, Japan 13, Australia 14 and letter size M/L.

For a men’s shirt, choose Men’s shirts and find your collar size. A US 15.5 inch collar is a European 39, for a neck of about 39 to 40 cm.

Measuring yourself

Use a soft tape measure and keep it level and snug, not tight.

  • Chest or bust: around the fullest part.
  • Waist: around your natural waist, usually just above the belly button.
  • Hips: around the widest part.
  • Neck: around the base of the neck, plus one finger for comfort.

Buying for someone else

If you are buying a gift, look at the label of something they already wear and convert that size here. When in doubt, choose a slightly larger size and keep the receipt, since a little room is easier to live with than a tight fit, and many shops offer gift returns.

Tips

  • Read the reviews. Shoppers often say whether an item runs small or large.
  • Check the fabric. Stretchy fabrics are more forgiving than stiff ones.
  • Size up for layering. Coats and jackets worn over thick jumpers may need one size more.

Common mistakes

  • Assuming a UK 12 is a US 12. It is closer to a US 8.
  • Ignoring Italian sizes. Many designer brands use them, and they run larger in number than EU sizes.
  • Buying by letter size only. M in one brand can be L in another.

Frequently asked questions

Are clothing sizes the same for every brand?

No. Sizes vary between brands, countries and even styles, and some brands use "vanity sizing", labelling clothes a size smaller than they are. Use the converter as a starting point and check the brand's own size chart and measurements.

Why are US and UK women's sizes different?

They use different number scales. A US women's size is usually 4 smaller than the UK size for the same fit, so US 10 is about UK 14. EU, Italian, Japanese and Australian sizes use their own scales too.

How do I measure for a men's suit or shirt?

For suits and jackets, measure around the fullest part of your chest under your arms. For shirts, measure around your neck where the collar sits, with one finger of space. The charts show these measurements in centimeters.

What do sizes like M/L mean?

Some sizes fall between two letter sizes. M/L means the size sits between medium and large, so it may fit either depending on the brand.

Which measurement matters most when buying online?

The one for the part that must fit closely: chest for jackets, neck for shirts, waist for trousers, and bust, waist and hips for dresses. Compare your measurements with the seller's chart.
