Foot Length and Shoe Chart Guide

Measure both feet while standing, then compare the longer measurement with a current size chart you choose. This works with a brand, retailer or local chart you already trust.

Your measurements and pasted chart stay in this browser. They are not uploaded or saved.

Use the tool

Global length comparison · use a current chart for the exact brand, model and intended age group.

Paste your shoe chart

Paste 2–100 data rows, optionally with a heading row, one per line: size label, length in the selected chart unit. Use a comma, semicolon or tab. Example: Size 40; 258. Lengths must not decrease from smallest to largest. Use the exact chart’s age group and fit instructions.

Used only when the pasted values are shoe interior lengths; choose the amount recommended by the maker or your own preference.

Enter both foot measurements and paste a current shoe chart.

The ISO conversion standard is a guideline; its tables are not reproduced here.

How to use it

If your left foot is 252 mm and your right foot is 258 mm, the longer foot is 258 mm. Paste a chart with size labels and the corresponding foot or shoe-interior lengths to compare it locally.

Compare a chart you choose

The tool converts mm, cm or inches into millimetres, uses the longer of your two feet and finds the closest length in the chart you paste. A toe allowance is added only when your chart column describes shoe interior length. Mondopoint is shown as the measured foot length in millimetres; it is not converted into another system.

Common questions

Why do I have to provide a shoe chart?

Size charts and fit guidance differ by maker, model and sizing system. Use a current chart for the exact shoe instead of relying on a generic cross-country conversion.

Which foot should I use?

Measure both feet standing, and compare the longer measurement. Feet can differ in length.

Is the closest chart row a guaranteed fit?

No. Shoe shape, width, socks and personal fit matter. This is a length comparison, not a fit guarantee; follow the maker’s guidance and try the shoe when possible.

Does Mondopoint give a UK, US or EU size?

No. It displays the foot length in millimetres. This tool does not reproduce copyrighted cross-system conversion tables.

Scope and limits

No default country, adult/child category or brand size table is assumed. The chart is supplied by you and is interpreted locally. The match is informational, not a guarantee of fit. Official standard references are linked below; the conversion chart itself is not bundled.
