How to Convert Vintage Clothing Sizes
Vintage clothing sizing is not standardised across countries or decades. A US size 14 dress from the 1950s is roughly equivalent to a modern US size 8, because manufacturers have gradually added extra room to the same size labels — a practice called vanity sizing.
This free converter maps US, European (EU), and Soviet (USSR) sizes for women's and men's clothing, shoes, and bras across three eras: early vintage (1920s–40s), mid-century (1950s–70s), and modern vintage (1980s–90s).
US vs EU Vintage Sizes
American women's sizing traditionally used even numbers starting around 0, while European sizing runs roughly 30–32 units higher. A US women's size 12 is approximately a EU 42. Men's jackets in the US use chest inches (38, 40, 42…) while the EU range runs from 44 to 62.
USSR / Soviet Clothing Sizes Explained
Soviet clothing sizes were standardised under GOST (the state standards body) from the 1960s onward. Garment sizes equal half the chest measurement in centimetres — a USSR 48 equals a 96 cm chest. Shoe sizes follow GOST 9135, essentially using Paris points like the European system. Soviet bra sizing matched Continental European standards exactly.
Why Vintage Sizes Run Small
Before the 1980s, garments were cut to the natural waist, which sits higher than the hip. A pair of trousers labelled "size 14" in 1960 may have only a 27–28 inch waist. Always measure before buying vintage pieces online.
How to Measure for Vintage Clothing
Use a soft tape measure held snugly (not tight) and record: bust at the fullest point, waist at the natural indentation (1–2 inches above the navel), and hips at the fullest point, roughly 7–9 inches below the waist. For shoes, trace your foot on paper and measure the longest dimension in centimetres.
