Tip: For best accuracy, enter your size exactly as labeled on your garment (e.g., "M" not "Medium").
How to Use This Tool
Follow these simple steps to convert your clothing size:
- Select the clothing type (tops, pants, dresses, or shoes) from the dropdown.
- Choose the gender category (men's, women's, or kids') for the garment.
- Pick the source sizing system (the system your current size uses) and the target system (the system you need to convert to).
- Enter your size exactly as labeled in the source system (e.g., "M" for tops, "32" for pants).
- Click the Calculate button to see your converted size and fit details.
- Use the Reset button to clear all inputs and start a new conversion.
Formula and Logic
This tool uses standardized international sizing charts from major global apparel brands to map equivalent sizes across regions. Conversions are based on industry-standard measurements for chest, waist, and inseam (for pants) or foot length (for shoes). For example, a women's US size S top corresponds to a UK size 8, EU size 36, AU size 8, and JP size 7. The tool cross-references your input size against the selected clothing type, gender, and source system to find the matching size in the target system.
Practical Notes
Keep these lifestyle-specific tips in mind when using this converter:
- Sizing can vary slightly between brands, even within the same region. Always check the brand's specific size chart if available.
- For pants, inseam length is not converted here—only waist size. You may need to adjust inseam separately for a proper fit.
- Kids' sizes are based on age (e.g., 2T for 2-year-olds) but may vary by child's height and weight.
- Shoe sizes convert based on foot length in centimeters, so measure your foot for the most accurate result.
- When shopping for dresses, note that fit (slim, regular, oversized) can affect size selection beyond standard conversions.

Frequently Asked Questions
Is this converter accurate for all brands?
No, sizing varies between brands even within the same region. This tool uses industry-standard averages, so always check the specific brand's size chart if possible for the most accurate fit.
Can I convert shoe sizes with this tool?
Yes, select "Shoes" as the clothing type. The converter supports standard shoe size conversions between US, UK, EU, AU, and JP systems for men's, women's, and kids' shoes.
What if my size isn't listed in the results?
If your size doesn't appear, it may not be in the standard conversion chart. Double-check that you entered the size correctly, or refer to the brand's official size guide for specialty sizes (e.g., plus sizes, petite fits).
Additional Guidance
For the best results when using this tool:
- Take your measurements (chest, waist, hips, inseam) with a flexible tape measure before converting sizes.
- When in doubt between two sizes, size up if the brand runs small, or down if it runs large.
- Save your converted sizes for frequently shopped regions to speed up future purchases.
- Note that vintage clothing may use older sizing systems not included in this converter.
