Shoe Measurement Methods Compared

Millimetres are the shared sizing axis, but the measurement method changes the error range. Compare Brannock, tracing, printable rulers and wall marks before buying online.

Key takeaways

Keep foot length in millimetres as the shared reference across US, UK, EU and CM systems.
Measure both feet while standing, ideally late in the day when feet are at their largest.
Use the larger foot as the buying reference; a shoe that is too short is harder to fix than a little extra volume.
After the formula, check the brand and model page because fit offset can move the final size by a half size or more.
