Our Conversion Process

1. Reference standard body measurement ranges defined by sizing authorities
2. Map equivalent sizes across US, UK, EU, and AU systems using overlap in measurement ranges
3. Present closest equivalent sizes (some systems do not have exact 1:1 mappings)
4. Display conversion in an interactive table format for easy lookup

What is EU size 38 in US clothing?

EU 38 is a US size 8 in women's clothing. The offset between EU and US dress sizes is roughly 30: subtract 30 from the EU number to get the US size. So EU 36 is US 6, EU 38 is US 8, EU 40 is US 10, and EU 42 is US 12. This applies to dresses, tops, and pants. Shoe sizing uses a different scale.

How do I convert US shoe size to UK?

For women's shoes, subtract about 2 from your US size to get the UK equivalent. A US 8 is roughly a UK 5.5 to 6. The exact offset can vary by half a size depending on the brand, so treat this as a starting point. EU shoe sizes follow a completely different numbering system where US 8 is approximately EU 38 to 39.

Is UK size 12 the same as US size 12?

No. UK 12 and US 12 are different sizes. A UK 12 equals a US 8 in women's clothing. UK sizes run about 4 numbers higher than US sizes for the same garment. This catches a lot of first-time international shoppers off guard, so always double-check which country's sizing system a brand uses.

Are clothing sizes consistent across all brands?

No. Sizing varies between brands and sometimes even between different items from the same brand. A Zara EU 38 can fit differently than an H&M EU 38 because of vanity sizing and different fit models. Our converter gives you standard equivalents based on international sizing standards, but checking the brand's own size chart is always worth the extra minute.

What is vanity sizing and how does it affect conversions?

Vanity sizing means labeling clothes with a smaller number than the garment actually measures. A US size 8 today is physically larger than a US size 8 from 20 years ago. It varies by brand and region. This is one reason why measurement-based tools, like our Body Shape Calculator, give more reliable results than size labels alone.

What is EU shoe size 39 in US?

EU 39 is approximately a US women's size 8.5 to 9. EU shoe sizes use the Paris point system where each size equals 6.67mm of shoe length. The exact US equivalent depends on the brand, so use this conversion as a guide and try shoes on when possible.

Can I use this converter for Zara, H&M, or ASOS?

Yes, as a starting point. Our converter gives you the standard international equivalent, then you can adjust based on how the brand fits. Zara tends to run small (size up 1), H&M runs slightly large due to vanity sizing, and ASOS is generally true to UK sizing. We list more brands in our sizing guide above.

Why do UK and US shoe sizes use the same numbers but fit differently?

UK and US shoe sizes share a numbering system but are offset by about 2 sizes for women. A US 8 is approximately a UK 5.5 to 6. The EU system uses a completely different scale where US 8 equals roughly EU 38 to 39. Always use a converter rather than assuming the numbers match across countries.

What size is EU 40 in US clothing for men?

EU 40 is a US/UK men's shirt size small. Men's shirt sizing in the EU generally runs S = EU 38, M = EU 40, L = EU 42, and XL = EU 44. For pants, the systems work differently: EU sizing runs about 16 higher than the US waist in inches, so a US 32 waist is an EU 48.

How do I convert kids' clothing sizes between countries?

US, UK, and AU kids' sizes are based on age (a US size 6 is roughly a UK 5-6 and an AU 6), while EU sizes are based on the child's height in centimeters (that same size is about EU 116). Because EU sizing tracks height rather than age, measure your child before ordering from a European brand, especially if they are tall or small for their age.

What is the formula to convert EU shoe size to US?

For women, subtract roughly 30 to 31 from the EU shoe size to estimate the US size (EU 38 is about a US 7.5 to 8). EU shoe sizes are based on the Paris point system, where each whole size equals 6.67mm of internal shoe length, so the exact US equivalent can shift by half a size depending on the brand's last.

Are men's and women's shoe sizes the same numbering system?

No. US men's and women's shoe sizes use the same scale but are offset by about 1.5 to 2 sizes: a US women's 8 is roughly a US men's 6 to 6.5. UK sizing is shared between men's and women's shoes without an offset, which is why UK sizes are often used as the reference point for cross-gender conversions.

How many centimeters is a US women's size 8 shoe?

A US women's size 8 shoe corresponds to a foot length of approximately 24cm (9.4 inches). This is an approximation based on standard shoe-industry length charts; exact fit still depends on the shoe's width and the brand's last shape.

Why do clothing sizes vary so much between brands?

There is no single global body-measurement standard that every brand follows. Companies also use vanity sizing, labeling garments with smaller numbers than their actual measurements to appeal to shoppers, and fit models differ by brand and target customer. That is why the same labeled size can measure differently at two stores, and why checking a brand's own size chart is always worth the extra minute.
