You pick a clothing category, a source system and size, and a target system. The tool looks up the position of your size in the source system's ordered list, then returns the size at the same position in the target system. No measurement-based formula is involved — it is a direct positional mapping between standardized size charts.
They're approximate. Clothing sizes are not standardized globally, and brands within the same country often size differently. Always check the specific brand's size chart when ordering online.
The converter includes half sizes for shoes but uses standard whole sizes for tops and bottoms. If you fall between two sizes, try both and choose based on your preferred fit.
This tool uses a general unisex reference chart. Men's and women's sizing can differ significantly — for example, a US women's shoe 8 is roughly a men's 6.5. Check a gender-specific chart for precise conversions.
Japanese women's clothing traditionally uses odd-numbered sizing (5, 7, 9, 11, etc.) where the number loosely relates to body measurements in a Japanese industrial standard. It's a convention rather than a direct centimeter measurement.
