Shoe Size Converter — EU / UK / US / cm

For men's footwear: US ≈ EU − 33, UK ≈ EU − 34. For women's: US ≈ EU − 30, UK ≈ EU − 33. For example men's EU 42 is approx. US 9 and UK 8. These are indicative conversions — makers use slightly different numbering.

Stand barefoot on paper in the evening, trace the foot with a vertical pencil and measure from heel to longest toe in cm. Measure both feet, take the larger value and add 0.5–1 cm of margin.

Approximately EU size = foot length (cm) × 1.5 + 2. A 26.7 cm foot corresponds to EU 42. This is a simplified model — real maker charts may differ slightly.

Makers use their own lasts and charts, so size 42 in one brand may equal 41.5 or 42.5 in another. Differences also stem from fit, shoe type and country of origin. Check the specific maker chart.

Yes, at the same EU size women's and men's footwear have different US and UK conversions. A woman in EU 38 is approx. US 8 and UK 5, while a man in EU 38 is approx. US 5 and UK 4.

Children's feet grow fast — re-measure every 2–3 months. Add approx. 1–1.5 cm of margin. Avoid buying shoes more than one size too big, as they hinder walking.

Best in the evening or after walking, when the foot is slightly larger due to natural swelling. A morning measurement may be too small and lead to tight shoes.

A small difference is normal. Size to the larger foot. For a notable difference (over half a size) consider levelling insoles in the smaller shoe.

Leave about 0.5–1 cm of free space before the longest toe. Too little causes blisters, too much lets the heel slip. Running shoes need a larger margin (up to 1 cm).

The converter uses simplified standard conversions. Results are indicative and work well as a starting point. Before buying online, compare with the brand official size chart.
