Your Sizing Queries, Answered.

What is the Universal Size Chart Converter?

It's an online tool designed to help you easily convert clothing and shoe sizes between various international sizing standards (e.g., US, UK, EU, Japan, etc.). We provide converters for men's, women's, and kids' footwear and apparel, including specialized converters for bras, belts, hats, and rings.

How accurate are the conversions?

Our conversions are based on extensive data collected from industry standards, official charts, and common practices across different regions. We strive for the highest possible accuracy. However, due to factors like "vanity sizing," brand-specific variations, and differences in garment fit, these conversions should always be used as a guide. For the most precise fit, we recommend checking the specific brand's size chart if available.

What is "My Fit Profile" and how does it work?

My Fit Profile is a personalized feature that allows you to save your key body and foot measurements (e.g., foot length, bust, waist, hips, underbust, inseam, sleeve length) directly in your browser's local storage. Once saved, these measurements can be automatically loaded into our various converters, providing instant, personalized size recommendations without needing to re-enter your data every time. You can find and manage your full profile on the home page.

Is my "My Fit Profile" data secure?

Yes, your measurements saved in "My Fit Profile" are stored exclusively in your browser's local storage. This means the data never leaves your device and is not transmitted to our servers or any third parties. It's completely private to you. If you clear your browser's data, your saved profile will be removed.

Why do clothing and shoe sizes vary so much internationally?

Different countries and regions have historically developed their own sizing systems, often based on different measurement units (inches vs. centimeters) or typical body proportions. Furthermore, brands may use their own interpretations of these standards, and "vanity sizing" (where a smaller number corresponds to a larger actual size over time) can further complicate matters. This site aims to bridge these gaps!

How do I get accurate measurements for optimal conversion?

For the most accurate results, use a flexible tape measure. Our site features dedicated guides on "How to Measure Your Foot" and "How to Take Accurate Body Measurements" (found on the home page under Informative Guides). We highly recommend reviewing these before saving your measurements to your Fit Profile.

What if I don't see my specific size or country listed?

While we strive to be comprehensive, some less common sizes or regional systems might not be explicitly listed. In such cases, using your actual body or foot measurements (in CM) and converting from those is often the most reliable method. We are continuously expanding our database, so check back for updates!

What is "vanity sizing"?

"Vanity sizing" refers to the practice where clothing manufacturers assign smaller sizes to garments that actually have larger physical measurements. For example, a "size 8" today might have the same dimensions as a "size 12" from a few decades ago. This is done to make consumers feel better about their size, but it contributes to inconsistency across brands and time periods.
