Everyone says that Barbie has unrealistic proportions, but have you seen them? Denise Winterman at the BBC decided to make a visual, borrowing one Barbie doll, one real human woman, Libby, and the wonders of photoshop.

First, Barbie’s measurements:

  • bust 4.6ins (11.6cm)
  • waist 3.5ins (8.9cm)
  • hips 5ins (12.7cm)

Second, the transformation:

Writes Winterman:

If Libby’s waist size of 28ins (71.1cm) were to remain unchanged, then applying Barbie’s proportions to her would mean Libby shoots up in height, to an Amazonian at 7ft 6ins (2.28m) tall. That’s just two inches shorter than the world’s tallest woman, Yao Defen. She would also have hips measuring 40ins (101.6cm) and a bust of 37ins (83.9cm).

But what if, instead, Libby’s height of 5ft 6ins (1.68m) was to remain unchanged. Doing the maths, Libby would have an extraordinarily tight waist of just 20ins (50.8cm), while her bust would be 27ins (68.5cm) and her hips 29ins (73.6cm).  Even the famously slight Victoria Beckham reportedly only has a 23ins (58.4cm) waist. But neither are they unheard of — Brigitte Bardot was famous for her 20ins (50.8cm) waist.

Citing scholarship, Winterman reports that “the likelihood of a woman having Barbie’s body shape is one in 100,000. So not impossible, but extremely rare.”
