Clothing Size Conversion: US, UK & EU Guide
Convert men's and women's clothing sizes across US, UK, and EU standards. Use our guide and free converter tool to find your international fit every time.
Shopping for clothes from international retailers is easier than ever, but navigating US, UK, and EU size labels can still be confusing. Whether you are buying a dress from a European boutique or ordering a suit from a UK brand, our clothing size converter takes the guesswork out of finding your match.
Below is a practical breakdown of how men's and women's clothing sizes compare across the three major sizing systems.
Men's Suits, Shirts & Pants
Men's suit jackets and blazers typically use a chest measurement in inches for the US and UK, while EU sizes use half the chest circumference in centimeters. For example, a US 40 jacket roughly equals a UK 40 and an EU 50. Dress shirts use neck circumference (inches) in the US and UK versus collar size in centimeters in the EU. Pants follow waist and inseam measurements in inches for US and UK, while EU pants are labeled in centimeters.
Women's Dresses, Tops & Bottoms
Women's clothing sizing is where the biggest differences appear. A US size 6 is approximately a UK size 10 and an EU size 38. US sizes typically run 2 to 4 sizes smaller than UK sizes and about 30 numbers lower than EU sizes. Tops use bust measurements, while bottoms rely on waist and hip dimensions. Always refer to the specific brand's size chart alongside our international clothing size converter for the best accuracy.
Measuring Yourself for the Best Fit
The most reliable way to convert sizes is to know your own body measurements. Use a soft measuring tape to record your chest, waist, hips, and inseam. Compare these numbers against the brand's size chart rather than relying on your usual label size. For children's sizing, check our kids size converter for age and height-based conversions.
