How do I convert US dress size to EU?

To convert US dress sizes to EU, add 30 to the US size for most women's clothing. For example, US size 8 equals EU size 38. However, this is a general rule and can vary by brand and clothing type. Our converter provides accurate conversions across all major sizing systems including US, UK, EU, China, and Japan.

Are clothing sizes the same across all brands?

No, clothing sizes can vary significantly between brands, even within the same country. This is known as "vanity sizing" or size inconsistency. Always check each brand's specific size chart when possible. Our converter provides standard international conversions as a starting point, but individual brand measurements may differ by 1-2 sizes.

What measurements do I need to find my size?

For accurate sizing, measure your bust/chest, waist, and hips in inches or centimeters. For tops, bust and waist are most important. For bottoms, focus on waist and hip measurements. Use a soft measuring tape, keep it parallel to the floor, and measure in the morning for consistency. Compare your measurements to size charts rather than relying solely on your usual size.

How do Chinese clothing sizes compare to US sizes?

Chinese sizes typically run smaller than US sizes. A Chinese size L often equals a US size S or M. Chinese sizing also uses a different numbering system (e.g., 165/88A) where the first number is height in cm and the second is bust/waist measurement. When shopping from Chinese retailers, always check measurements in centimeters and size up 1-2 sizes from your US size.

Understanding International Clothing Sizes

International clothing size conversion can be confusing when shopping online or traveling abroad. Different countries use different sizing systems, and even within the same country, sizes can vary between brands. Our converter helps you navigate these differences with accurate conversions.

Major Sizing Systems

United States (US)

US sizes use numerical sizing (0, 2, 4, 6, 8, etc.) for women and letter sizes (XS, S, M, L, XL) or chest measurements for men. US sizes tend to run larger than European sizes.

United Kingdom (UK)

UK sizes are typically 2 sizes larger than US sizes for women (US 8 = UK 12). Men's sizing is similar to US but may vary by brand.

European Union (EU)

EU sizes use a different numbering system (34, 36, 38, 40, etc.). Generally, add 30 to US women's sizes to get EU sizes (US 8 = EU 38). Men's sizing uses chest measurements in centimeters.

China (CN)

Chinese sizes typically run 1-2 sizes smaller than US sizes. They often use a height/measurement system (e.g., 165/88A where 165 is height in cm). Always check measurements when buying from Chinese retailers.

Japan (JP)

Japanese sizes run small compared to Western sizes. A Japanese M is often equivalent to a US XS or S. Japanese sizing uses numbers (5, 7, 9, 11) or letters (S, M, L).

How to Measure Yourself

Bust/Chest: Measure around the fullest part of your chest, keeping the tape parallel to the floor
Waist: Measure around your natural waistline (smallest part of your torso)
Hips: Measure around the fullest part of your hips and buttocks
Inseam: For pants, measure from crotch to ankle along the inside of your leg
Tips: Measure in the morning, wear minimal clothing, don't pull the tape too tight

Size Conversion Tips

Always check the specific brand's size chart when available
Read customer reviews for sizing feedback
When between sizes, size up for a more comfortable fit
Consider the fabric—stretchy materials are more forgiving
Asian sizes (China, Japan) typically run smaller—size up 1-2 sizes
Luxury brands may have different sizing than fast fashion
Vintage clothing often uses older sizing standards (smaller)

Common Sizing Challenges

Vanity Sizing

Many brands use "vanity sizing" where sizes are labeled smaller than actual measurements to make customers feel better. This means a size 8 from one brand may fit like a size 10 from another.

Body Shape Variations

Standard sizes assume certain body proportions. If you have a different body shape (pear, apple, hourglass, etc.), you may need different sizes for tops and bottoms.
