Conversion chart around your size
The row matching your computed length sits at the top of the range.
Formulas are the standard linear approximations used by most conversion charts — but there is no ISO standard for US or UK sizing. Brands (Nike, Adidas, ECCO, Clarks…) routinely run a half size large or small, so treat results as a starting point and check the brand's own size guide.

Formula
US Men ≈ 3 × (length in) − 22 · UK = US M − 1 · US W = US M + 1.5 · EU ≈ 1.5 × (cm + 1.5)
Pro tips
- • Measure feet at the end of the day when they are largest, standing with weight on both feet.
- • If between sizes, size up for running shoes (toe swell) and down a half for dress leather that stretches.
