What is the International Shoe Size Converter?
The International Shoe Size Converter is a professional-grade tool designed to eliminate the confusion and frustration of shopping for shoes across different sizing systems. Whether you're shopping online from international retailers, traveling abroad, or simply trying to understand the differences between US, UK, European, and other international sizing standards, this tool provides precise, reliable conversions.
Developed with input from certified shoe fitting specialists and based on official sizing charts from major footwear manufacturers, our converter takes into account the subtle but important differences in how various regions measure and categorize shoe sizes. Unlike simple conversion charts that often provide inconsistent results, our tool uses advanced algorithms that consider factors such as shoe type, gender, and regional fitting preferences.
The tool is particularly valuable for online shoppers who frequently encounter sizing discrepancies between brands and regions. With the global footwear market becoming increasingly accessible through e-commerce, understanding these conversions has become essential for making confident purchase decisions and avoiding costly returns.
How to Use the International Shoe Size Converter
Step 1: Select Your Known Size
Start by entering your shoe size in the sizing system you're most familiar with. Choose from US, UK, European (EU), or other international systems. Make sure to specify whether you're looking for men's, women's, or children's sizes, as the conversion ratios differ significantly between these categories.
Step 2: Choose Target Sizing System
Select the sizing system you want to convert to. This is particularly useful when shopping from international retailers or when traveling to countries that use different sizing standards. The tool supports all major international sizing systems including Japanese, Korean, and specialized athletic sizing.
Step 3: Specify Shoe Type (Optional)
Different types of shoes may fit differently even within the same size. Athletic shoes, dress shoes, boots, and sandals often have varying fits. Selecting the specific shoe type helps provide more accurate conversion recommendations tailored to that style's typical fit characteristics.
Step 4: Review Detailed Results
The tool provides not just the converted size, but also additional information such as typical fit variations, brand-specific recommendations, and tips for ensuring the best fit when ordering online. Pay attention to the fit notes and consider sizing up or down based on your personal preferences.
Step 5: Save or Share Results
Save your conversion results for future reference or share them when shopping with others. The tool also provides printable sizing charts that you can keep handy while shopping online or in stores.

Frequently Asked Questions
Professional Tips & Best Practices
Measure Your Feet Regularly
Foot size can change over time due to age, weight changes, or medical conditions. Measure your feet annually for the most accurate sizing.
Shop for Shoes in the Afternoon
Feet naturally swell throughout the day. Shopping in the afternoon ensures you get a size that accommodates this natural expansion.
Consider Sock Thickness
The type and thickness of socks you plan to wear can affect sizing. Athletic socks require more room than thin dress socks.
Check Return Policies
Always verify return and exchange policies when ordering shoes online, especially when using size conversions between different systems.
