US Men's Size vs Foot Length
How Shoe Size Systems Work
Each sizing system has a different scale based on foot length. This calculator converts using approximate formulas.
Approximate Formulas
EU = Foot Length (cm) x 1.5 + 2
US Men's and UK are based on barleycorn increments (1/3 inch) from reference points.
Always try shoes on, as sizing varies by manufacturer.
Example Calculation
Foot length of 27 cm.
- 01US Men's = (27 - 22) x 3 / 2.54 + 3 = 8.9
- 02UK = (27 - 22) x 3 / 2.54 + 2.5 = 8.4
- 03EU = 27 x 1.5 + 2 = 42.5, rounded to 43
