Understanding Shoe Sizing Systems
Different regions developed independent sizing systems before international standardization. Understanding these systems helps interpret conversion results and brand-specific variations.
US Sizing (Brannock)
Based on the Brannock Device invented in 1927. Each size increment equals 8.46mm (⅓ inch).
- Separate men's and women's scales
- Women's sizes ~1.5 higher than men's
- Includes half sizes
- Width designations available (N, M, W, 2E)
UK Sizing (Barleycorn)
Uses the historical barleycorn unit where each size equals ⅓ inch. UK sizes are typically 0.5-1 smaller than US for same foot length.
- One of the oldest sizing systems
- Similar increments to US
- Generally unisex (some brands differ)
- Used in UK, Australia, India
EU Sizing (Paris Point)
Based on the French Paris point where each size equals 6.67mm (⅔ cm). EU sizes are typically 30-33 higher than US men's sizes.
- Generally unisex system
- Smaller increments than US/UK
- Used across Europe
- Some brands add half sizes
Mondopoint (ISO)
The international ISO 9407 standard measuring foot length and width in millimeters. Most accurate system available.
- Direct mm measurements
- No conversion needed
- Used for technical footwear
- Basis for our foot length calculator
Conversion Accuracy & Limitations
What Our Calculators Do Well
- Follow ISO 9407 standard formulas

Frequently Asked Questions
Are these shoe size calculators free to use?
Yes, all 8 shoe size calculators on Yawteef are completely free. No signup, registration, or payment is required. Simply select a calculator, enter your size or measurement, and get instant results.
Which calculator is the most accurate?
The Foot Length to Shoe Size Calculator is the most accurate because it uses your actual foot measurement rather than converting between sizing systems. Direct measurement eliminates cumulative conversion errors and aligns with the ISO 9407 Mondopoint standard.
How accurate are shoe size conversions?
Our conversions are based on ISO 9407 standards and industry-standard sizing charts. Size-to-size conversions are approximations that work for most major brands. For best results, measure your foot length directly and verify with brand-specific size guides.
Do these calculators work for all shoe brands?
These calculators provide standardized conversions that work for most major brands. However, athletic brands (Nike, Adidas, New Balance), luxury brands (Gucci, Prada), and specialty footwear may have variations. Always check the brand's specific size chart when available.
What's the difference between EU and US shoe sizing?
EU sizing uses the Paris point system where each size equals 6.67mm and is generally unisex. US sizing uses the Brannock system where each size equals 8.46mm with separate scales for men's and women's footwear. EU sizes are typically 30-33 units higher than equivalent US men's sizes.
How do I convert between men's and women's shoe sizes?
In US sizing, women's sizes are approximately 1.5-2 sizes higher than men's for the same foot length. For example, a men's US 8 equals approximately a women's US 9.5-10. Use our Men's to Women's or Women's to Men's converters for automatic calculation.
When should kids switch to adult shoe sizes?
Children typically transition from youth to adult sizing around ages 10-12 when their feet reach approximately 22-24cm (8.5-9.5 inches). Youth size 7 is equivalent to Men's 7 or Women's 8.5. Use the Kids to Adult Converter to find the exact equivalent.
Which calculator should I use for online shopping?
For online shopping, use the Foot Length Calculator for best accuracy, or the International Converter to compare your size across multiple systems. For shopping from specific regions, use the appropriate regional converter (EU to US for European brands, US to UK for British retailers).
