What This Tool Does
Vintage Size Converter is a free, browser-based size conversion tool built for anyone buying, selling, or wearing vintage clothing. It translates sizes across three major historical standards — US, EU, and Soviet/USSR — and accounts for how those standards shifted decade by decade from the 1920s through the 1990s.
Everything runs locally in your browser. No sign-up, no account, no data sent to a server. Just pick your category, era, and size — and get the conversion instantly.
Categories Covered
- Women's tops — blouses, dresses, jackets
- Women's bottoms — trousers, skirts
- Men's clothing — shirts, suits, coats
- Shoes — both men's and women's lasts
- Hats — head circumference to size label
- Bras — band and cup across all three systems
Why Vintage Sizing Is Complicated
Clothing sizes were never globally standardised. The US, Europe, and the Soviet Union each developed independent measurement systems tied to their own manufacturing norms. On top of that, vanity sizing shifted label numbers upward over the decades — a dress labelled size 14 in 1955 fits closer to a modern size 8 or 10.
Soviet clothing followed GOST standards (государственный стандарт), introduced systematically from the 1960s onward. Earlier Soviet and pre-war Russian garments used a mix of pre-revolutionary measurements and European conventions, making era context essential for accurate conversion.
This tool surfaces era-specific notes alongside every conversion so you understand not just the number, but the context behind it.
How to Get the Best Result
Size labels are a starting point, not a guarantee. For the most reliable fit, take your body measurements with a soft tape measure and compare them to the centimetre charts shown after each conversion. Pay attention to:
- Bust — at the fullest point, tape held snug but not tight
- Waist — at the natural indentation, 1–2 inches above the navel
- Hips — at the fullest point, roughly 7–9 inches below the waist
- Inseam — for trousers, from crotch seam to ankle bone
Vintage garments were often constructed with less ease (extra room) than modern clothing, and natural fibres like wool and cotton shrink with washing. When in doubt, size up.
