Method
Approximate retail formulas map foot length plus an allowance to EU, UK and US labels; Mondopoint keeps millimetre length directly.
Everyday worksheet
Foot-Length Shoe Size Guide
Estimate common adult regional labels from measured foot length and show adjacent half sizes as a fitting range.
The calculation runs locally. Results include the intermediate values, unit conversions and assumptions needed to audit the answer.
Method, assumptions and practical use
How the Foot-Length Shoe Size Guide works
Approximate retail formulas map foot length plus an allowance to EU, UK and US labels; Mondopoint keeps millimetre length directly. Inputs stay in this browser, and the result table exposes conversions and assumptions for independent checking.
Interpret the result
Measured foot length is the most portable result; regional labels are approximate starting points.
Check the assumptions
Brand last, width, toe room, socks, activity and grading vary. Measure both feet standing and use the larger foot with the brand chart.
Local calculation
Everything runs in this browser. Inputs are not sent to an external calculator.
Rounding
Displayed values may be rounded for readability while calculations use full floating-point precision unless the tool explicitly uses exact integers.
Scope
Brand last, width, toe room, socks, activity and grading vary. Measure both feet standing and use the larger foot with the brand chart.
Simple by design
