Formula
EU Size = US Size + 31.5 (men) or US Size + 32 (women)
EU sizes are based on the Paris Point system (⅔ cm increments). Men's US sizes add 31.5 to get EU; women's add 32, reflecting the different offset between US women's and men's sizing conventions. UK sizes subtract 1 (men) or 2 (women) from US sizes. Centimeter foot length approximates EU size × 0.667 (⅔ cm per Paris Point).

Understanding Shoe Size Systems
The world uses three main shoe size systems: US (traditional American), EU/European (Paris Point), and UK (British). The US and UK systems use barleycorn units (⅓ inch increments). EU sizes use Paris Points (⅔ cm per size). The conversion offsets differ by gender because women's US sizes were historically set two sizes higher than men's for the same foot length. When in doubt, measure your foot and use the centimeter result to check the brand's size chart.
Sizing Varies by Brand
Shoe size conversions are approximations. Even within the same size system, Adidas tends to run half a size larger than Nike. Luxury brands like Gucci and Prada may follow Italian sizing (same as EU but sometimes labeled differently). Always check the specific brand's size chart when available, especially for online purchases. Many brands publish foot-length-to-size charts in both inches and centimeters for the most accurate fit.
Tips & Insights
Measure in the Afternoon
Feet swell throughout the day. Measure foot length in the afternoon for the most accurate size — buying shoes sized for morning feet can lead to tightness by evening.
Check Brand-Specific Size Charts
This calculator gives a standard conversion. For expensive purchases, always cross-reference with the brand's own size chart and read customer reviews mentioning fit.
Half Sizes Are Common
If your US size ends in .5 (like 10.5), the EU result will also end in .5 (like 44). Many European brands do not carry half sizes — size up if between sizes.

Frequently Asked Questions
Are US men's and women's shoes sized differently?
Yes. Women's US sizes are about 1.5-2 sizes larger than men's for the same foot length. A women's US 8 fits the same foot as a men's US 6.5 approximately.
What is a Paris Point?
A Paris Point is the unit of the EU size system, equal to ⅔ of a centimeter (approximately 6.67 mm). Each EU size step represents ⅔ cm of additional foot length.
Why does the EU size not match exactly between men and women?
The offset differs (31.5 vs. 32) because US women's sizing starts at a different base than US men's sizing, even though the EU system is gender-neutral.
Do children's sizes use the same conversion?
No. Children's shoe size conversions have different offsets. This calculator covers adult US sizes only.
What if my EU size falls between standard sizes?
EU 41.5 is a real and common size. If a brand only offers full EU sizes, a US 10 men would fit EU 42 better than EU 41 in most cases — size up.
