Foot Measurement Guide
- Stand on a sheet of paper with your heel lightly touching a wall.
- Mark the longest point of your toes, then measure from heel to toe in centimeters.
- Measure both feet and use the longer result when choosing a size.
- Compare your cm length with the chart above, then adjust for brand fit if needed.
Width Guide
Narrow
Feet that feel loose in standard shoes or need slim-fitting brands.
Standard
Most people fit best here. Start with regular width unless your shoes consistently pinch or slip.
Wide
Helpful if the toe box feels tight, the sides bulge, or you size up only for extra room.
Extra Wide
Best for very broad feet, orthotics, or all-day comfort when wide sizes still feel restrictive.
How to Use

Frequently Asked Questions
Is shoe sizing the same across all brands?
No. Brand sizing can vary slightly, especially between athletic, fashion, and work shoes. Use your foot length in centimeters as the most reliable starting point, then check the brand's own fit notes if available.
How do I measure my foot for shoe size?
Stand on paper, trace or mark your heel and longest toe, then measure that distance in centimeters. Measure both feet and use the longer one when comparing with a chart.
What is the difference between US, UK, and EU shoe sizes?
Each region uses its own scale, so the same physical foot length maps to different size numbers. That is why a converter or chart is useful when shopping from international brands.
Why does width matter when choosing shoes?
Length alone does not guarantee a good fit. If shoes feel tight at the sides, pinch your toes, or require sizing up just for comfort, you may need a wide or extra wide option instead of a longer size.
