First choose women’s, men’s, or children’s. Select the source system and enter the number you know. The result shows one shared table row; when the input falls between rows, the calculator clearly labels the nearest match as an approximation.
Body measurements before labels
Measure chest, waist, and hips with a level tape. Height is also important for children. Compare these measurements with the chart for the actual garment because a size label alone cannot describe fit.
Women’s, men’s, and children’s are separate
The three groups use different numbers and proportions. A women’s US 8 is not interchangeable with a men’s US size or a children’s age label. For children, the EU number generally represents body height in centimeters.
Example
A women’s EU 38 maps to US 6, UK 10, FR 40, and IT 42 in this general table. That is an international reference, not the centimeter measurements or fit of a particular dress.
Brand, cut, and fabric
A fitted jacket can run differently from a relaxed shirt by the same brand. Stretch, layering, product line, and preferred ease affect the choice. When measurements fall between sizes, compare both adjacent options.
Limits of the conversion
The calculator does not know brand-specific measurements, petite or tall sizing, cup sizes, unisex cuts, or individual proportions. Return and exchange terms also matter when shopping internationally.
Frequently Asked Questions
How do I measure chest, waist, and hips correctly?
Keep a flexible tape measure level. Measure chest and hips at their fullest point and the waist at its narrowest point without pulling the tape tight.
Why do sizes differ by brand?
Brands use their own blocks, target customers, and tolerances. Fabric, cut, and collection also change how the same size label fits.
How do I convert EU, US, and UK sizes?
Choose women’s, men’s, or children’s, then the known system and size. The calculator shows the corresponding or nearest table row in the other systems.
Are women’s and men’s sizes comparable?
No. Their numbers and proportions follow different tables, so always choose the appropriate size group.
What should I do if I am between sizes?
Compare chest, waist, and hip measurements with the brand chart. Cut, preferred ease, and stretch determine which adjacent size is more suitable.
Does this replace the manufacturer’s size chart?
No. The manufacturer’s measurements for the specific garment are more precise than a general international conversion.
