Reading Your Results

The output produced by the Shoe Size Conversion gives you a precise baseline to work from. If you are comparing multiple scenarios, you can easily change a single input to see how it directly affects your overall Shoe Size Conversion.

Use this calculated figure to make more informed decisions moving forward.

How to use this calculator

1Enter the shoe size.
2Select the source sizing system (From).
3Select the target sizing system (To).
4Click "Calculate."

The calculator finds the equivalent size using the appropriate international shoe size conversion table.

Converted Size = Lookup(Source Size, Source System → Target System)

Where

Source Size = The entered shoe size
Source System = The original sizing standard (US, UK, EU, CM, etc.)
Target System = The sizing standard to convert into

Foot Length Conversion

Foot Length (cm) = Foot Length (inches) × 2.54
Foot Length (inches) = Foot Length (cm) ÷ 2.54

Example 1

Input Size = US Men’s 9
Convert To = UK
Using the standard conversion table: UK Size = US Size − 1
UK Size = 9 − 1 = 8

Example 2

Input Size = UK Women’s 6
Convert To = EU
Using the standard conversion table: EU Size = 39

Example 3

Input Size = EU 42
Convert To = US Men’s
Using the standard conversion table: US Men’s Size = 9

Example 4

Input Size = Foot Length 27.0 cm
Convert To = Inches
Foot Length (inches) = 27.0 ÷ 2.54 = 10.63 inches
