How to Use Our Size Charts
Step 1: Choose Your Category
Start by selecting the type of size chart you need. We offer comprehensive charts for shoes, clothing, bras, rings, and hats. Each category includes detailed conversion tables for different international sizing systems.
For example, if you're shopping for shoes, click on "Shoe Size Charts" to access brand-specific charts and international conversions.
Step 2: Find Your Current Size
Locate your current size in your local sizing system (US, UK, EU, JP, CN, etc.). If you're unsure of your size, we recommend measuring yourself first using our measurement guides.
For the most accurate results, use body measurements (chest, waist, hips for clothing; foot length for shoes) rather than relying solely on size labels.
Step 3: Convert to Your Target Size
Use the conversion table to find the equivalent size in your target sizing system. Each chart shows side-by-side comparisons across multiple international standards, making it easy to find your perfect fit.
Remember that sizing can vary between brands, so always check brand-specific charts when available.
Step 4: Consider Brand-Specific Fit
Different brands may have slightly different fits even within the same size system. Our brand-specific charts include sizing notes and fit characteristics to help you make the best choice.
When in doubt, size up for comfort, especially for items that can't be easily adjusted like shoes and rings.

Frequently Asked Questions
Why do I need to use size conversion charts?
Different countries and regions use different sizing systems, which can make online shopping confusing. For example, a US size 10 shoe is different from a UK size 10 or EU size 10. Size conversion charts help you find the equivalent size in your target system, ensuring you order the right size when shopping internationally.
Additionally, even within the same sizing system, different brands may have slightly different fits. Our brand-specific charts help account for these variations.
How accurate are these size conversion charts?
Our conversion charts are based on international sizing standards and official brand guidelines. However, sizing can vary between different models, styles, and even colorways. We recommend using these charts as a starting point and checking model-specific sizing notes when available.
For the most accurate fit, we always recommend measuring yourself and comparing those measurements with the size chart, rather than relying solely on size labels.
What if my size falls between two sizes on the chart?
If your measurements fall between two sizes, we generally recommend sizing up for comfort, especially for items that can't be easily adjusted like shoes and rings. A slightly larger size can often be adjusted with insoles, thicker socks, or resizing, while a size that's too small can cause discomfort.
For clothing, consider the fit style you prefer (slim, regular, or relaxed) and the brand's specific sizing notes when making your decision.
Can I use these charts for all brands?
Our general conversion charts provide a good starting point for most brands, but fit can vary significantly between different brands and even between different models from the same brand. We recommend checking our brand-specific charts when available, as they include brand-specific sizing notes and fit characteristics.
For brands not covered in our brand-specific charts, use the general conversion charts as a guide, but always check the brand's official size chart and customer reviews when possible.
