TRIVIAL PURSUITS: How tall would Barbie be in real life?

By PS

While some calculations used to present Barbie’s proportions in life size have estimated she would reach 7’ 6”, most calculations put her at around 6’ tall.  

Most calculations also estimate Barbie would have a 22” to 28” waist, but one analyst who says these calculations are flawed, estimates Barbie’s waist at 55 ½”.
