Standing at 183cm, with size 13 feet, I am well acquainted with the "tall" label. According to statistics I'm a rare breed, falling in the upper 99th percentile for height for an Australian woman.

If you're 175cm (5ft 9 inches) tall, for example, then your waist measurement should be less than 87.5cm (34 inches) - or half your height. Measuring ... pregnant women or children under two.
