How the converter calculates shoe size
EU size is derived from the input system: from cm: EU = length × 1.5 + 2 from US: EU = US + 33 (men) / + 30 (women) from UK: EU = UK + 34 (men) / + 33 (women) From EU size: Foot length = (EU − 2) ÷ 1.5 US = EU − 33/30, UK = EU − 34/33
Example: men's EU size 42
Men's EU size 42: foot length = (42 − 2) ÷ 1.5 ≈ 26.7 cm, US = 42 − 33 = 9, UK = 42 − 34 = 8. The same shoe in the women's system would have different US and UK equivalents.
Frequently asked questions
How do I convert shoe size from EU to UK and US?
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.
How do I measure foot length at home?
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.
What is the relation between foot length and EU size?
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.
Why does the same size fit differently across brands?
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.
Do women's and men's shoe sizes differ?
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.
How do I pick a child's shoe size?
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.
What time of day should I measure my foot?
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.
What if my feet are different lengths?
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.
How much margin should I leave in a 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).
Is the shoe size converter accurate?
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.
