👗 Dress Size Calculator
Convert a women’s dress size between the US, UK, and EU sizing systems.
Why dress sizes differ by country
Women’s dress sizes are numbered differently around the world even for the same actual body measurements. A US size 8 is not the same number as a UK size 8 — it’s actually a UK size 12.
How this calculator works
This calculator uses the standard size chart offsets used by most Western clothing brands: UK Size = US Size + 4, and EU Size = US Size + 32. Enter your size and which system it’s in, and it converts to the other two using these fixed offsets.
These offsets reflect general industry sizing conventions, but individual brands often use their own size charts based on actual body measurements (bust, waist, hip), so fit can vary noticeably between brands even at the ‘same’ converted size.
Use this as a helpful starting point when shopping internationally; checking a specific brand’s own measurement chart will always be more accurate.
