Women's Clothing Size Converter
Use this women's clothing size converter to translate dress and top sizes between the US, UK, EU, Italian and French systems. International shopping is full of mismatched labels — a US 8 is a UK 12 and an EU 40 — so enter the size you know and see the equivalents at a glance.

Formula used
Women's sizing is matched from standard conversion charts rather than a formula, because each country uses a different numbering scheme for similar body measurements. As rough anchors:
US + 4 ≈ UK · US + 32 ≈ EU · EU + 4 ≈ IT
The calculator matches your input to the nearest standard row and shows every system. For the best fit, compare your bust, waist and hip measurements to the brand's own size chart.
Worked examples
US 8 ≈ UK 12, EU 40, IT 44, FR 40.
UK 10 ≈ US 6, EU 38.
EU 42 ≈ US 10, UK 14.

Vanity sizing means a label can vary by several centimetres between brands — measurements beat labels.
Who should use this converter
Anyone shopping internationally — from a UK site, a European boutique, or an Italian label — who needs to translate an unfamiliar size. It's also handy for gifting clothes when you only know the recipient's home-country size.
Why measurements beat labels
Numeric sizes only approximate body measurements, and “vanity sizing” means the same label varies widely between brands and over time. The reliable approach is to measure your bust, waist and hips, then match them to the specific brand's size chart. Use this converter to get in the right range, then confirm with the numbers.
How to measure yourself
- Bust: around the fullest part, tape level and not tight.
- Waist: around the narrowest part of the torso.
- Hips: around the fullest part, feet together.
Compare these to the retailer's chart for the closest fit.
Limitations of this converter
Conversions are matched to standard charts and rounded to the nearest size. Cut, fabric stretch, and brand-specific sizing all affect fit, and garment type (dress vs jeans) can size differently. Treat the result as a starting point, not a guarantee.
Frequently asked questions
What is a US 8 in UK and EU sizes?
A US 8 is approximately a UK 12 and an EU 40 (IT 44, FR 40). Always confirm with the brand's chart.
Why is my UK size different from my US size?
The UK and US use different numbering for similar measurements — UK numbers run about four higher than US for women's wear.
Are clothing size conversions exact?
No. They're matched to standard charts and rounded; vanity sizing and brand differences mean you should check measurements for a precise fit.
How do I find my size if brands differ?
Measure your bust, waist and hips and compare to each retailer's specific size chart rather than relying on the label number.
Do Italian and French sizes differ?
Slightly. Italian women's sizes typically run a few numbers higher than French/EU for the same body measurements.
