Why Dress Sizes Don't Match Across Countries

There's no single global sizing standard for women's clothing — every country built its own numbering system independently, decades apart, around different reference bodies. A US 8 and a UK 8 were never meant to be the same garment, even though they use the same digit. That's the entire reason conversion charts exist: not because the numbers are inconsistent by accident, but because they were never the same system to begin with.

How To Use This Converter

Pick the country whose size you already know, choose that size from the second dropdown, and you'll get the equivalent across US, UK, EU, Italy, France and Australia instantly. It's especially handy right before ordering from an overseas boutique, a UK or European resale site, or a size label you don't recognize on a secondhand piece.

A Few Things The Chart Can't Account For

Vanity sizing. Many US brands quietly size their labels smaller than the industry standard used to be — a modern US 8 often fits like an older US 10-12. Fast-fashion and luxury labels tend to run truer to the standard chart than mall staples do.
Cut and silhouette. A bodycon dress and a shift dress in the "same" size can fit completely differently. When a brand publishes its own measurement chart, trust that over any general conversion.
Petite, tall and plus ranges. These usually follow their own separate charts rather than a straight scale-up or scale-down of standard sizing.

Reading An Italian Or French Size Tag

Italian sizes run a few points above the equivalent EU size (a EU 40 is roughly an Italian 44), which trips people up constantly when shopping directly from Italian labels. French sizing sits closer to standard EU numbering, usually just two points above it.

Frequently Asked Questions

No — a UK 12 is roughly a US 8. UK sizing runs about four points above the equivalent US size, which is one of the most common mix-ups when shopping from British retailers.

There is no legally enforced sizing standard in fashion, so every brand sets its own chart based on its own fit model. This conversion tool bridges countries, but it can't bridge brand-to-brand differences — when in doubt, check that brand's own size chart.

Use the converted size as your starting point, then check the retailer's own body measurements (not just the size number) against your own if they're listed — that's the most reliable way to avoid a return.
