Convert shoe sizes between US, UK, EU, and JP systems for men and women. Includes foot length in cm and inches.
The free Shoe Size Converter instantly translates shoe sizes between US, UK, European (EU), and Japanese (JP) sizing systems for both men and women. Just select your gender, choose your known size system, enter your size, and see all equivalent sizes instantly.
Shoe sizing varies significantly across countries. US and UK sizes use different starting points and gender offsets. European sizes follow the Paris point system (each size = 6.67 mm). Japanese sizes are measured in centimeters of foot length. Shopping internationally or online can be frustrating without accurate conversions.
Our converter accounts for gender-specific offsets: women's US sizes are typically 1.5 sizes higher than men's for the same foot length. UK men's sizes are roughly 0.5 less than US men's, while UK women's sizes are roughly 2 less than US women's. The tool also shows foot length in centimeters.
By calculating this metric accurately, professionals gain actionable insights that support smarter work habits, more realistic scheduling, and improved work-life balance over time.
International shoe shopping requires accurate size conversions. This tool handles gender offsets across all four major systems and eliminates guesswork when ordering from overseas retailers. Precise quantification supports meaningful goal-setting and accountability, ensuring that improvement efforts are focused on areas with the greatest potential impact on output. Data-driven tracking enables proactive schedule management, helping professionals protect focused work time and reduce the cognitive overhead of constant task-switching throughout the day.
Men: EU = US + 33 (approx), UK = US - 0.5, JP = (US + 18) × (2.54 / 2.54) in cm. Women: US_W = US_M + 1.5, UK_W = US_W - 2, EU_W = US_W + 31 (approx). Foot length (cm) ≈ (US_M + 18) × 0.847 (varies by manufacturer).
Result: UK 9.5 / EU 43 / JP 28
A men's US 10 converts to UK 9.5 (US minus 0.5), EU 43 (US plus 33), and JP 28 cm. The approximate foot length is 28 cm or 11 inches.
Modern shoe sizing originated in the 14th century with the barleycorn system in England. One barleycorn (1/3 inch) equals one size increment. The US adopted a modified version in the 1880s with a different starting point. Europe developed the Paris point system where one size = 2/3 cm.
Since sizing systems are approximations and brands interpret them differently, measuring your foot length in centimeters is the most reliable way to find your size in any system. Stand on paper, mark heel and longest toe, and measure the distance.
Shoe width is just as important as length for comfort. Standard widths are B (narrow), D (standard for men), and E/EE (wide). Some systems don't account for width, so check brand-specific width guides when ordering internationally.
A US men's 10 is approximately EU 43. The exact EU size can vary by manufacturer, so checking foot length in cm (about 28 cm for US 10) gives the best fit.
Women's US sizes are typically 1.5 sizes higher than men's for the same foot length. So a women's US 8.5 is equivalent to a men's US 7. UK and EU have their own gender offsets.
Japanese shoe sizing (JP or JPN) is based on foot length in centimeters. If your foot measures 26 cm, your JP size is 26. It's the most straightforward sizing system.
There is no universal standard enforced for shoe sizing. Each brand uses its own lasts (foot models) and may interpret sizing charts differently. Foot length in cm is the most reliable cross-brand measurement.
Shoe size converters provide approximate equivalents based on standard charts. Actual fit depends on the brand, shoe style, foot width, and arch shape. Use the converter as a starting point and consult brand-specific charts when available.
No. For men, UK sizes are about 0.5 less than US sizes (US 10 = UK 9.5). For women, UK sizes are about 2 less than US sizes (US 8 = UK 6). The scales are different.
