Free Clothing Size Converter
Convert clothing and shoe sizes between US, UK, EU, and Australian sizing instantly. Free international size converter for dresses, tops, pants, and shoes.
A clothing size converter translates garment sizes between international sizing systems so you can shop from any country with confidence. A US women's size 8 equals UK 12, EU 40, and AU 12. The European EN 13402 standard and ISO 8559 define how body measurements map to size labels, though brand-specific variations mean conversions are starting points, not guarantees. For a more precise fit, pair this converter with our Body Shape Calculator to find your exact measurements.

How Our Converter Works
Our Conversion Process
- 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
What We Assume
- •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
What to Keep in Mind
- •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
About Accuracy
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.
Important Things to Know
When Conversions May Not Match
- !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 to Double-Check Your Size
- ⚠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

How to Convert Your Clothing Size
Follow these six steps to find your size in any international sizing system. The whole process takes about a minute.
Know Your Size in One System
Start with the size you normally wear in any one country, whether that is US, UK, EU, or AU. If you are unsure, use our Body Shape Calculator to find your measurements first.
Select a Clothing Category
Choose what you are shopping for: dresses, tops, pants, or shoes. Each category uses its own conversion table because sizing systems differ across garment types.
Find Your Size in the Table
Locate your known size in the conversion table. For example, if you wear US 8, find the row that starts with US 8.
Read Across for Other Systems
Read across the row to see equivalent sizes in other countries. US 8 converts to UK 12, EU 40, and AU 12.
Check the Brand Sizing Guide
Scroll down to our Popular Brand Sizing Guide to see if the brand you are shopping from runs large, small, or true to size. Adjust your converted size accordingly.
Verify with the Brand Size Chart
Before purchasing, check the brand own size chart on their website. Our conversion gives you a strong starting point, but individual brands can vary from standard sizing.

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.
