Convert clothing sizes between US, UK, EU, AU, and JP systems for men and women. Includes tops, bottoms, and dresses.
The free Clothing Size Converter maps sizes between US, UK, European (EU), Australian (AU), and Japanese (JP) systems for both men and women. Select your gender, garment type, and known size to see equivalents in all five international sizing standards.
Clothing sizes are notoriously inconsistent — not just between countries but between brands within the same country. US sizes have experienced significant "vanity sizing" over the decades, where today's size 8 would have been a size 12 in the 1950s. European sizes use actual body measurements, and Japanese sizes are similarly metric-based.
This converter uses standardized mapping tables that reflect the most common equivalences. For the best fit, always check brand-specific size charts and measure your body dimensions (chest, waist, hips) in centimeters.
This structured approach transforms vague productivity goals into measurable targets, making it easier to track improvement and stay motivated toward meaningful professional achievements. By calculating this metric accurately, professionals gain actionable insights that support smarter work habits, more realistic scheduling, and improved work-life balance over time.
Shopping internationally or from overseas brands requires accurate size conversion. This tool eliminates confusion between five major sizing systems and covers men's and women's garments. Having accurate figures readily available simplifies project planning, deadline negotiation, and workload balancing conversations with managers, clients, and team members. Consistent measurement creates a reliable baseline for evaluating personal efficiency and identifying the habits and practices that contribute most to achieving professional goals.
Women's Tops: US = UK - 4, EU = US + 30, AU = US + 4, JP = US + 5 (approx). Men's Tops (chest): EU = US + 10 (approx). Women's Bottoms: US_W(pants) = (waist_inches - 21), EU = US + 30. Mappings are approximate and based on industry-standard charts.
Result: UK 12 / EU 38 / AU 12 / JP 13
A US women's size 8 top is approximately UK 12 (US + 4), EU 38 (US + 30), AU 12 (US + 4), and JP 13 (US + 5). Sizes may vary by brand; always verify with body measurements.
The US system uses arbitrary numbers (0—20+ for women, S–XXL or chest inches for men). UK sizing is similar but offset by 4 for women. European sizing is metric-based, roughly corresponding to half the chest measurement. Australian sizing mirrors UK for women. Japanese women's sizing uses odd numbers starting at 5 or 7.
US clothing sizes have drifted significantly. A size labeled “8” today has measurements that would have been a “12” or “14” decades ago. This makes vintage shopping and international ordering especially confusing. Body measurements in cm are the only reliable constant.
Always check the brand's size chart before ordering internationally. Measure yourself with a soft tape in underwear. Compare your measurements to the chart rather than relying on your usual size number. Many brands offer fit guides and customer size reviews.
For women's tops and dresses, US 8 is approximately EU 38. For women's pants, it's also around EU 38. Men's sizing follows a different mapping where US chest-based sizes add about 10 for EU.
UK women's sizes are typically 4 numbers higher than US sizes. So a US 6 is a UK 10, a US 8 is a UK 12, and a US 10 is a UK 14.
Japanese women's sizes use odd numbers (7, 9, 11, 13, 15). Men's sizes often use S/M/L/XL or centimeter-based chest measurements. JP sizing tends to run smaller than Western sizes.
For women, AU and UK sizes are very similar and often identical. However, some Australian brands may differ slightly. Always check the brand's specific chart.
There's no legally enforced sizing standard. Brands target different body shapes and demographics, and vanity sizing leads companies to label garments smaller than their actual measurements to make customers feel smaller.
Measure your bust (for tops) or waist (for bottoms) in centimeters. Your EU size is roughly your bust measurement divided by 2, minus a small adjustment. For example, a 92 cm bust is about EU 38.
