What should your waist measurement be? For men, a waist circumference below 94cm (37in) is 'low risk', 94–102cm (37-40in) is 'high risk' and more than 102cm (40in) is 'very high'. For women, below 80cm (31.5in) is low risk, 80–88cm (31.5-34.6in) is high risk and more than 88cm (34.6in) is very high.
Ideally, your waist measurement should be less than half of your height. (So if you're 5 foot 6, or 66 inches, your waist circumference should be less than 33 inches.)
The bottom line
The average American woman's waist size is 38.7 inches. Also, the average American woman is 63.6 inches tall and weigh 170 pounds. All of these numbers are indicators of health, but not predictors.
In general if you're a woman, you want a measurement that's less than 34.5 inches. If you're a man, a number below 40 inches is ideal. A measurement that's higher than those isn't a death sentence, but it has been strongly linked with a higher risk of several serious diseases including type 2 diabetes.
A waist circumference above 80 cm for women and above 94 cm for men is associated with an increased risk of chronic conditions. A waist circumference above 88 cm for women and above 102 cm for men is associated with a substantially increased risk of chronic conditions (WHO 2000).
Do at least 30 minutes of moderate-intensity activity five or more days per week. Better yet, strive to get 45 to 60 minutes each day. Even if you don't lose weight with aerobics, you can lose visceral fat as well as gain muscle mass.
A woman's health is at risk if her waist circumference is 32 inches or more. A measurement of 35 or more puts you at high risk for a heart attack or stroke. People with a high level of abdominal fat have a much higher chance of developing cardiovascular disease and type 2 diabetes.
Runway models must have precise measurements so they're able to fit the clothes that designers are going to be showing to their clients. Their measurements are usually no greater than 34 inches around the bust, 23 inches around the waist, and 34 inches around the hips.
Generally speaking, a 28-inch waist is on the small side and indicates low abdominal fat, a marker of good health. However, having a slim waist doesn't automatically make you healthy. And you must also consider other diet and lifestyle factors.
Causes of a High Waist Circumference
A larger waist circumference is often caused by intra-abdominal visceral fat. Visceral fat is fat that develops between and around internal organs. This type of fat differs from "regular" fat that sits just beneath the skin and can be pinched.
What should your waist measurement be? For men, a waist circumference below 94cm (37in) is 'low risk', 94–102cm (37-40in) is 'high risk' and more than 102cm (40in) is 'very high'. For women, below 80cm (31.5in) is low risk, 80–88cm (31.5-34.6in) is high risk and more than 88cm (34.6in) is very high.
Finally, the researchers question the current guidelines, “recommending that a single waist circumference threshold for white adults (men greater than 102 centimeters [cm]; women greater than 88 cm) be used to denote a high waist circumference, regardless of BMI category.”
Waist circumference measurement is an easy way to assess body fat levels in your midsection. However, it can't tell you your overall body fat percentage.
It depends what you means by “normal.” Medically, the advice these days is for a woman to have a waist less than 32 inches [81.5 cm] and 36 inches [91.5 cm] for a man. Above those measurements is regarded by the medics as indicating overweight and loss of control over diet, exercise, lifestyle generally.
The average waist size for American women is 35.6 inches. That means a 30 inch waist would put you in the 15th percentile among most females, which is quite a bit smaller than average. However, it's important to remember that 3 out of 4 adult women in the US are overweight or obese.
Remember, the CDC recommends pacing yourself at 1 to 2 pounds of overall weight loss per week. So, it could take 1 to 2 months before you notice your waistline shrinking.
For example: If you have a 32 inch waist, your size is a US-Size M or Euro-Size 42.
In women, the waist measurement should not be over 80 cm. Those at a very high risk include men with a waist circumference of over 102 cm and women with a waist circumference of more than 88 cm.
