How to measure yourself

Use a soft tape measure over thin clothing and keep it level and snug, not tight. For the bust or chest measure around the fullest part. For the waist measure the narrowest part of the torso, usually just above the belly button. For the hips measure around the fullest part of the seat. For kids, measure height standing barefoot against a wall.

If your measurements fall between two sizes, size up for a relaxed fit and down for a tailored one, and for stretchy fabrics the smaller size usually works.

Why clothing sizes differ

There is no single worldwide clothing size standard. The UK women's size is the US size plus 4, the EU size is the US size plus 32, and the Italian size is the EU size plus 4, but these are conventions that brands follow loosely. Men's UK and US sizes are the same, and are simply the chest or waist measurement in inches, while the EU men's top size is that number plus 10 and the EU trouser size is the waist in inches plus 16. Treat the conversion as a reliable starting point rather than a guarantee, and check the brand's own chart when you can.

A worked example: a UK 14 dress, converted

Worked example

You usually buy a UK 14, and you're shopping on an American site. In the converter, pick Women's, convert from UK, and choose 14.

You get US 10, EU 42, AU 14 and IT 46, a letter size of M, and the measurements that size is built for: about 96 cm bust, 77 cm waist and 102 cm hips. Compare those three numbers with your own tape measure. If they match, order the size. If they don't, go by the measurements, not the label.

The rules of thumb

You don't need a chart for most of this. Here's the quick version:

Women's: UK = US + 4. EU = US + 32 (or UK + 28). Italy = EU + 4. Australia matches the UK.
Men's tops and suits: US and UK sizes are the chest measurement in inches. EU is that number plus 10.
Men's trousers: US and UK sizes are the waist in inches. EU is that number plus 16.
Kids: the EU size is the child's height in centimetres.

Why a size 12 isn't always a 12

There's no worldwide standard for clothing sizes. Each brand decides its own, and many brands have quietly made their sizes larger over the years so customers feel they fit a smaller number (it's called vanity sizing). The result: the same person can be a 10 in one shop and a 14 in another. Fabric matters too. A stretchy knit forgives a size, while a stiff woven fabric doesn't.

So treat the label as a starting point and the measurements as the truth. Brands that publish a size chart in centimetres are doing you a favour, so use it.

How to shop internationally without guessing

Measure yourself with a soft tape, over thin clothes. Bust or chest, waist and hips.
Find the brand's own size chart, and compare your measurements with it, not just the size label.
Use the converter above to see how the brand's system matches the one you know.
Check the fabric. If it has stretch, you have more room. If it doesn't, be strict.
Read a few reviews. "Runs small" or "true to size" is the most useful thing a stranger can tell you.
If you're between sizes, go up for a relaxed fit and down for a close fit.

Shirts are sized by the collar

Men's formal shirts are sized by the collar, not by S, M or L. In the UK and US that's in inches, and in Europe it's in centimetres. Here's how they line up, roughly:

Collar (in)	Collar (cm)	EU shirt size
15	38	38
15½	39	39–40
16	41	41
16½	42	42
17	43	43

Kids: go by height, not age

Children of the same age can be 10 cm apart in height, so "age 6" on a label is a guess. Measure the child's height, standing straight without shoes, and use the Kids' tab. If they're between sizes, buy the bigger one. Children grow quickly, and a size that's slightly big is more useful than one that's slightly small.

Why this matters

Clothing is one of the most-returned things people buy online, and wrong sizing is one of the main reasons. A couple of minutes with a tape measure before you order saves you the return, the postage and the wait.

Frequently asked questions

What is the difference between US and UK clothing sizes?

For women's clothing a UK size is the US size plus 4, so a US 8 is a UK 12. For men's tops, suits and trousers the US and UK use the same numbers, which are the chest or waist measurement in inches.

How do I convert a UK dress size to EU?

Add 28 to the UK size: a UK 12 is an EU 40 and a UK 8 is an EU 36. Italian sizes are the EU size plus 4, so a UK 12 is an IT 44.

What are the standard measurements for each size?

A US women's 8 (UK 12) fits a bust of about 91 cm, a waist of about 72 cm and hips of about 97 cm. The chart on this page lists the measurements for every size, but brands cut differently, so always check the maker's own chart if they publish one.

How do I measure myself for clothes?

Use a soft tape measure over thin clothing. Measure the fullest part of the chest or bust with the tape level, the narrowest part of the waist, and the fullest part of the hips. Keep the tape snug but not tight, and type the number into the measurement option in the converter.

Why does the same size fit differently between brands?

Clothing sizes are not governed by a single standard. Each brand sets its own fit and sizing, and fast-fashion brands often cut smaller than their label suggests (called vanity sizing). Use the conversion as a starting point and check reviews and the brand's own size guide.
