👣 Cultural Sizing History
🇺🇸 US Sizing System
The US system uses the "Barleycorn" measurement (1/3 inch per size) dating back to English cobblers in 1324. Men's and women's sizes differ by about 1.5 sizes. The current numbering system was formalized in 1880 by Edwin B. Simpson using last measurements. Wide feet variations (+E, +EE) reflect America's diverse foot shapes.
🇬🇧 UK Sizing System
Developed from children's sizing (13 infant sizes starting at 0). Uses barleycorns (1 size = 1/3 inch) starting at 12/30 cm. The UK remains the only system where children's and adult sizes use the same scale.
🇪🇺 EU (Paris Point)
Based on Paris Points (2/3 cm per size). Modern EU sizing uses foot length in centimeters with formula: EU size = foot length(cm) × 1.5 + 2. Includes width codes (N narrow, M medium, W wide).
🇯🇵 Japanese Sizing
Uses centimeter measurements (1 size = 0.5 cm) with separate systems for genders. JIS S 5037 requires exact foot length labeling. Traditional "sun" measurements (≈3.03 cm) used until WWII.
🇰🇷 Korean Sizing
KS M 6681 standard uses metric measurements (1 size = 5mm) with narrow lasts. Military boots use unique 0.25 cm increments. Children's sizes (120-240mm) use 5mm increments.
🇮🇳 Indian Sizing
Blends UK sizing with +0.5 size adjustment for wider feet. Regional variations: Mumbai (narrow), Delhi (medium), Kolkata (wide). Traditional kolhapuri chappals use "mutthi" finger measurements.
🌍 Global Variations
Notable systems: Mexican "punto" (6.67mm/size), Brazilian "número" (4mm), Chinese "hao" (1cm), Russian GOST. Mondopoint system uses pure metric measurements.
