Are Clothing Sizes Standardized?

No. Labels vary substantially by brand, country, garment and intended fit. Your body measurement and the product's own chart are more reliable than label conversion alone.

How Should I Measure?

Keep a flexible tape level and close to the body without compressing it. Measure over the undergarments you expect to wear with the garment.

What Is the Clothing Size Converter?

The Clothing Size Converter uses a body measurement rather than assuming that two printed size labels are equivalent. It provides a starting international, US, UK and EU range for women's tops, men's tops and unisex waist-sized pants, while keeping the source measurement visible.

How It Works

Select the garment fit, choose inches or centimeters and enter the requested full-bust, chest or natural-waist measurement. Use the result as a starting point, then compare it with the size chart for the exact brand and garment.

When to Use It

Use it when shopping across regional labels or when a store displays only one sizing system. It cannot account for a brand's fit block, ease, fabric stretch, cut or vanity sizing.
