Clothing Size Converter
Convert clothing sizes between US, UK, European, and international sizing systems for men, women, and children. Find your perfect fit across different brands and countries.
Why Do Clothing Sizes Differ Between Countries?
Clothing sizes vary worldwide because each country developed its own sizing system independently. The US uses numerical sizes (0–24 for women, S–3XL for men), the UK uses a similar but offset system (UK sizes are typically 4 numbers higher than US for women), and the EU uses centimeter-based measurements (EU 36–56).
This converter maps sizes across US, UK, EU, and International (S/M/L) systems for women's tops, bottoms, and bras, men's shirts and pants, and children's clothing. Select your gender, clothing type, and current size to see equivalents in all systems instantly.

How to Measure Yourself for the Best Fit
What You Need
A flexible measuring tape, a mirror, and thin clothing (or measure over underwear). Stand straight and relaxed. Don't pull the tape too tight — it should be snug but not compressing.
Bust / Chest
Wrap the tape around the fullest part of your chest, keeping it level across the back. For women, measure over the fullest part of the bust while wearing a non-padded bra.
Waist
Measure around your natural waistline — the narrowest part of your torso, usually just above the belly button. Bend sideways to find the crease; that's your natural waist.
Hips
Stand with feet together and measure around the fullest part of your hips and buttocks. Keep the tape level and parallel to the floor. This is typically 7–9 inches below your natural waist.
FAQ – Clothing Size Converter
What is a clothing size converter?
A clothing size converter translates sizes between different international sizing systems (US, UK, EU, International S/M/L). Since each country uses its own numbering, a US size 8 doesn't mean the same as a UK 8 or EU 8. This tool maps equivalent sizes across all systems for women, men, and children.
How do US and UK women's sizes compare?
UK women's sizes are typically 4 numbers higher than US sizes. A US 4 = UK 8, US 8 = UK 12, US 12 = UK 16. To convert US to UK, add 4. To convert UK to US, subtract 4. EU sizes use a different scale entirely (US 4 = EU 36).
How do EU clothing sizes work?
European sizes are based on body measurements in centimeters. For women, EU sizes typically range from 32 (XXS) to 56 (3XL). For men, they range from 44 (XS) to 56+ (3XL). The EU number roughly corresponds to half the chest measurement in centimeters for men's clothing.
Are men's sizes the same in the US and UK?
For most men's clothing (shirts, pants), US and UK sizes are the same or very similar. A US Medium is the same as a UK Medium. Men's pants use waist measurements in inches (28, 30, 32, etc.) which are consistent across both systems. The main difference is in EU sizing, which uses a different numbering system.
How do I convert children's clothing sizes?
Children's sizes vary the most between countries. US sizes use age-based labels (2T, 3T, 4T, then 5–16). UK sizes use age ranges (2–3, 3–4, etc.). EU sizes use height in centimeters (92, 98, 104, etc.). The converter maps all these systems so you can find the right equivalent.
Why do sizes vary between brands?
There's no universal standard enforced across brands. Each brand creates its own size chart based on their target customer. "Vanity sizing" is also common — some brands label clothes with smaller numbers to make customers feel better. Always check the specific brand's size chart when possible.
How do I convert bra sizes between US and EU?
US/UK bra band sizes use inches (30, 32, 34, 36, 38), while EU uses centimeters (65, 70, 75, 80, 85). To convert: US 30 = EU 65, US 32 = EU 70, US 34 = EU 75, US 36 = EU 80. Cup letters (A, B, C, D) are generally the same across systems, though some EU brands use different cup progressions.
What should I do if I'm between sizes?
If you fall between sizes, consider the garment type: for fitted items (blazers, dress shirts), size up for comfort. For relaxed items (t-shirts, casual wear), either size works. Check if the brand offers "regular" vs "slim" fits. When shopping online, look for the brand's specific measurements rather than just the size label.
How accurate are online size converters?
Size converters provide a reliable general guide based on standard international size charts. However, actual fit varies by brand, fabric stretch, cut style, and manufacturing. Use the converter as a starting point, then check the specific retailer's size guide. Body measurements (bust, waist, hips in inches/cm) give the most accurate results.
Do Asian clothing sizes differ from Western sizes?
Yes, significantly. Asian sizing (Japan, Korea, China) tends to run 1–2 sizes smaller than Western sizing. A US Medium might be an Asian XL or XXL. Japanese women's sizes use numbers like 7, 9, 11, 13 (odd numbers). Korean sizes often use measurements in cm (55, 66, 77). Always check Asian brand size charts carefully.
