Formula Used
Shoe sizing schemes are not perfectly standardized across regions or brands, so this tool uses linear approximations that match commonly published size charts.
For adult Men, the conversion is US ≈ EU − 33. For adult Women, US ≈ EU − 31.5. For Kids, US ≈ EU − 32.
These relationships are near‑affine across typical ranges and yield close alignment to many retailer charts.
You can keep fractional values as entered or switch to rounding modes that snap to the nearest half size or whole size.
A rough foot length estimate in centimeters is provided via length_cm ≈ EU − 1.5, which is a practical heuristic.
Always check brand-specific charts when available. If you are between sizes, consider the rounding mode and intended sock thickness or activity.
