Ideally, all should aim to keep their waist measurement less than half that of their height, found the scientists. That means a 6ft (72 inch) tall man should aim to keep his waist less than 36 inches, while a 5ft 4in (64 inch) woman should keep hers under 32 inches.They have found that the easy-to-calculate ratio between the two is a better predictor of risk than the most widely measure of obesity, called body mass index (BMI).hat means a 6ft (72 inch) tall man should aim to keep his waist less than 36 inches, while a 5ft 4in (64 inch) woman should keep hers under 32 inches.

Waist to height ratio is less accurate than BMI for me. I'm a 17Â¾ year old male with a BMI of 24.4 (77th percentile â healthy), waist to height ratio of 0.52 (consider action), and body fat percentage of 6.7% (on the verge of underweight) â measured using skinfolds.'m a 20 year old female 5'7 about 127 with lbs with a 27/28 inch waist. My bf said I have a pudge since having my son so I wanted to get a 25/26 inch waist but no matter what I do it stays the same, and on the chart it says take care at 26 for my height.
