Definition and Scope
A clothing size converter is a reference tool that maps equivalent garment sizes across different international sizing systems (US, UK, EU, AU) based on standardized measurement ranges.
Applies To
- ✓Women shopping internationally or from foreign brands
- ✓Converting dress, top, pants, and shoe sizes between regions
- ✓General guidance for online shopping from international retailers
Does NOT Apply To
- ✗Brand-specific sizing (varies significantly between manufacturers)
- ✗Custom or bespoke garments
- ✗Children's clothing (uses different sizing systems)
- ✗Men's clothing (different conversion tables)
- ✗Maternity wear (specialized sizing)
Edge Cases
- ⚠Vanity sizing practices vary by brand and region
- ⚠Vintage or pre-standardization garments may not conform to modern sizing
- ⚠Some European countries use country-specific variations of EU sizing
Methodology
How Results Are Derived
- Reference standard body measurement ranges defined by sizing authorities
- Map equivalent sizes across US, UK, EU, and AU systems using overlap in measurement ranges
- Present closest equivalent sizes (some systems do not have exact 1:1 mappings)
- Display conversion in an interactive table format for easy lookup
Assumptions Made
- •Sizing standards follow general industry conventions
- •User knows their size in at least one sizing system
- •Garment categories (dress, top, pants, shoes) use consistent sizing within each system
Simplifications Applied
- •Treats all brands within a region as using standard sizing (they do not)
- •Does not account for fit preferences (slim, regular, relaxed)
- •Presents single size equivalents rather than ranges for clarity
- •Does not differentiate between petite, regular, and tall sizing within a region
Uncertainty Declaration
Conversions are approximations based on standard sizing. Actual fit varies significantly by brand, garment style, and manufacturing. Always consult brand-specific size charts for best results.
Limitations and Known Issues
Failure Scenarios
- !Brand uses non-standard or proprietary sizing
- !User is between sizes in their primary system
- !Garment is designed for non-standard fit (oversized, cropped, etc.)
When Results May Mislead
- ⚠When shopping fast-fashion brands known for inconsistent sizing
- ⚠When purchasing from luxury brands with unique sizing conventions
- ⚠When body measurements fall at the boundary between two sizes
Version Notes
Conversion tables based on commonly accepted international equivalents. Individual brand sizing may differ substantially from these standards.

Popular Brand Sizing Guide
Even with standard conversions, brands size differently. Here is how popular international brands tend to fit compared to standard sizing.
| Brand | Region | Sizing Tendency | Tip |
|---|---|---|---|
| Zara | EU | Runs small | Size up 1 from your standard EU size |
| H&M | EU | Runs large (vanity sizing) | Size down 1 or stick with your standard size |
| ASOS | UK | True to UK size | Use our UK conversion directly |
| Uniqlo | JP | Runs small for Western customers | Size up 1-2 from your US/EU size |
| Mango | EU | True to EU size | Use our EU conversion directly |
| Nike | US | True to US size (shoes run narrow) | For shoes, consider half-size up for wide feet |
Sizing tendencies are based on general customer feedback and may vary by specific product line. Always check the brand's own size chart for the most accurate fit.
Frequently Asked Questions
Are clothing sizes consistent across all brands?
No, sizing can vary between brands and even between different items from the same brand. Our converter provides standard size equivalents, but we recommend checking the specific brand size chart when possible.
What regions does this converter support?
Our converter supports US, UK, European (EU), and Australian (AU) sizing for dresses, tops, pants, and shoes.
Do shoe sizes differ between countries?
Yes, shoe sizing systems vary significantly between countries. US, UK, EU, and AU all use different numbering systems, which is why a converter is helpful when shopping internationally.
Should I size up or down when shopping internationally?
If you are between sizes, it depends on your preference. For tops and dresses, consider how you like your clothes to fit. For shoes, many people prefer a slightly larger size for comfort.
What is vanity sizing and how does it affect conversions?
Vanity sizing is the practice of labeling clothes with a smaller size number than the garment actually measures. It varies by brand and region — a US size 8 today is larger than a US size 8 from 20 years ago. This is why measurement-based tools like our Body Shape Calculator give more accurate results than size labels alone.
How do I convert my US dress size to European?
To convert US to EU dress sizes, add 30 to your US size. For example, US 4 = EU 34, US 6 = EU 36, US 8 = EU 38, US 10 = EU 40. Our converter handles this automatically for dresses, tops, pants, and shoes across US, UK, EU, and AU systems.
Why do UK and US shoe sizes use the same numbers but fit differently?
UK and US shoe sizes share a numbering system but are offset by about 2 sizes for women. A US women's size 8 is approximately a UK size 6. The EU system uses a completely different scale (US 8 ≈ EU 39). Always use a converter rather than assuming the numbers match.
Can I use this converter for online shopping from Zara, H&M, or ASOS?
Our converter gives you the standard international size equivalent, which is a great starting point. However, fast fashion brands like Zara, H&M, and ASOS each have their own sizing variations. We recommend using our conversion as a baseline, then checking the brand's own size chart for the most accurate fit.
