Shoe Size Converter
Convert men's and women's shoe sizes between US, UK, EU, and centimeters.
So funktioniert's
This converter looks up your size in a standard sizing chart to translate men's or women's shoe sizes between the US, UK, EU, and centimeter (foot length) systems, which each use a different underlying numbering scale.
EU sizing (also called Paris point or Continental sizing) is based on foot length measured in a unit equal to two-thirds of a centimeter â this is why EU shoe sizes are larger raw numbers than US or UK sizes for the same physical foot length, and why they scale up in fairly fine, consistent increments.
US and UK sizing both use their own historical scales that don't correspond directly to a metric measurement, and men's and women's sizing charts differ within each country too â a US women's size is commonly about 1.5-2 sizes larger than the equivalent US men's size for the same actual foot length, which is why sizing charts specify men's versus women's separately.
Foot length in centimeters (or inches) is the most direct, brand-independent measurement â measuring the length from heel to the longest toe while standing (feet lengthen slightly with weight-bearing) gives a reference point that can be checked against any brand's own size chart, which is often more reliable than converting a size number between systems.
Shoe sizing charts are approximate because, similar to clothing, there's no single global manufacturing standard â actual fit also depends on width (which has its own separate sizing in some systems, like B/D/EE width designators in the US), the specific shoe's last (the foot-shaped mold it's built on), and the style of shoe itself.
When ordering shoes internationally or from an unfamiliar brand, checking the brand's specific size chart against a measured foot length in centimeters generally gives a more reliable result than relying purely on a size-number conversion, since brand-to-brand variation in how a labeled size actually fits can be significant.
Children's shoe sizing runs on its own separate scale from adult sizing in most systems, restarting the numbering from a small size and progressing until roughly the early teenage years, when a child's foot size typically transitions into the adult numbering scale â another reason to convert based on measured foot length rather than assuming a direct adult/child size relationship.
Are these sizes exact?
No â shoe sizing varies between brands. Use this as a general starting reference and try shoes on when possible.
Why are EU shoe sizes larger numbers than US or UK sizes?
EU sizing is based on foot length measured in units of two-thirds of a centimeter, producing a different (typically higher) numbering scale than the US or UK systems for the same actual foot length.
Is a US women's size the same number as a US men's size for the same foot length?
No â a US women's size is typically about 1.5-2 sizes larger in number than the equivalent US men's size for the same actual foot length, so men's and women's charts are listed separately.
What's the most reliable way to determine my shoe size?
Measure your foot length in centimeters from heel to longest toe while standing, then compare that measurement against the specific brand's own size chart rather than relying solely on a converted size number.
Does shoe width factor into this conversion?
No â this converts length-based size numbers between systems; width uses separate designators (like B/D/EE in the US) that aren't part of the standard length-based conversion.
Why might the same labeled size fit differently between two shoe brands?
Each brand designs shoes on its own "last" (the foot-shaped mold used in construction), so actual fit for the same nominal size can vary meaningfully between brands and even between styles from the same brand.
Should I measure my foot standing or sitting?
Standing â feet lengthen slightly when bearing weight, so a standing measurement gives a more accurate real-world foot length for sizing purposes.
Can this converter handle both men's and women's shoe sizes?
Yes â select the appropriate category, since men's and women's sizing scales differ even within the same country's system.
Does this converter cover children's shoe sizes?
No â this focuses on adult US/UK/EU/cm sizing; children's shoes typically use a separate numbering scale that transitions into adult sizing around the early teenage years.
Why does foot length in centimeters give a more reliable conversion than a size number?
A centimeter measurement is a direct physical quantity independent of any brand or region's arbitrary numbering convention, making it a more consistent reference point than converting between size-number systems alone.
