Baby & Kids Shoe Size Calculator
Result
Approximate a numerical EU children’s shoe-size index from measured foot length in cm. Not a UK/US converter or brand-specific fitting chart.
Formula
- Enter measured foot length in centimeters. The calculator displays an approximate EU-size index using (length + 1.2) × 1.5. Results may be fractional and do not guarantee a matching commercial shoe size. Check the specific manufacturer’s size chart and fit; this tool does not calculate UK or US sizes.
- The main inputs are Foot length. Enter them in the units and format shown in the calculator.
- Use the measurement units shown beside each field. The result is an estimate and should be interpreted in context.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Baby & Kids Shoe Size

What formula does this calculator use?
The calculator uses the following relationship: Illustrative EU-size numerical index = (foot length in cm + 1.2) × 1.5. This is a fixed approximation, not a brand-specific or standardized shoe sizing conversion; its fractional output is not a guaranteed available retail size. It does not compute UK/US sizes or check actual in-shoe allowance..
Why might my result differ from another source?
Results can differ because measurement methods, rounding and assumptions vary. This calculator is an estimate and is not a medical diagnosis.
Does the result update automatically?
Yes. Changing an input updates the result using the same calculation engine shown on this page.
