Percentile is the share of the group with shorter feet than this size fits. “1 in X” counts the rarer side: people at or beyond this value above the median, at or under it below. The size is converted to foot length in cm, then compared with a normal distribution of foot lengths.
What this means
- The average man's foot is 26.5 cm, about a US men's 10.5. The average woman's is 24.0 cm, about a US women's 8.5. A women's 10 is 1.4 cm longer than the women's mean.
- Measured against men, the same foot is longer than 20% of them. In US men's sizing it is about 9.
- Shoe sizes are not standardised. The same foot gets different numbers from different brands, usually by half a size, sometimes a whole one.
