Waist to height ratio

Waist to height ratio calculatorWaist to height ratio is a simple measurement for assessment of lifestyle risk and overweight. Compared to just measuring waist circumference, waist to height ratio is equally fair for short and tall persons. This calculator is valid for children and adults.

Instructions:
1. Measure your waist circumference at a horizontal line one inch above your belly button.
2. Enter waist circumference and height by turning the dials.

Ratio
0.47
OK
Waist
inches
80
Height
ft' in''
170

Background:

Measuring waist to height ratio is gaining popularity in the scientific society as several studies have found that this is a more valid measurement than BMI. Just measuring waist circumference is inherently biased for people taller or shorter than average population.

This calculator uses the criteria for interpretitation suggested by Ashwell.

this is not as accurate as BMI...this has me at .40, and if I loose one inch...it puts me in the "Take Care" category...HOWE VER, I am actually high on the BMI scale for normal. At 5'4" and 140 lbs, I am NOT at an ideal place for my body. I have very wide hips and large breasts, but a ridiculously tiny waist....I could stand to loose 14% of my body weight and am over 30% body fat.

I am a 16 year old teen male, and i have a waist size of 16, and i weigh 125 pounds, and my BMI is at a 40th percentile. I want to lose weight and get a six pack or at least a trim figure. I have extra fat around my stomach area, but to the outside world, it looks like i don't, but i know i have it. I am planning on cutting my caloric intake from 2000+ down to 1500-1200. I am planning on putting myself through an intense swiming workout(i was in swimteam this year but saw no improvment) and a hardcore abs workout. I'll try not to starve myself, howver, but it may comedown to that, becuase i have this girl that i really want to impress once i get the chance to ask her out, after she ends hopefully ends her current relationship.(i have not interrupted this yet, i'm friends with both of them, ask me some other time, this is a long, long story.) So i'm coming to the decison of rapidly cutting my caloric intake to next to nother if dieting dosen't work because i want to be skinny. PleaseAns

From the comments a lot of people are confused or at least worried. This is supposed to be an easy measurement. If you have a24inch waist you don't have to worry.

Please remember this is a tool to use as a guideline. If you are really worried about your body fat, see a Dr. They will measure some points on your body and use those numbers in conjunction with your height and weight to give you an actual body fat percentage to work from.

Wrestlers do this every season to get an idea of what is their optimal weight, and it is really the only (or, at least, best) way to see what your body composition is and what to do about it, if anything.

Quoting Syrena:
What is a healthy weight for a 5'5 sixteen year old girl? I weigh 98lbs and have a 22 inch waist, and it says to "take care".

At 5'5, under 100 pounds is crazy. Please, for your health's sake don't focus on your weight unless you balloon up to over 150ish, and even then edit till you're at least 21 to really worry about it. Before then your body will continually change and weight is not always an indication of health. If you're truly worried about it, see a Dr, but plz do NOT take the advice of a website that's set up for the general population, and mostly for adults at that.

According to this WHtR calculator you can only enter your waist and height in whole numbers. Also the ideal female WHtR is 38.2% and the ideal male WHtR is 44.7% (according to Adonis Index and Venus Index). So this calculator should be modified to allow waist and height in mixed fractions (e.g. waist=30.4, height=5'6.7") to get more accurate results. Also the normal range should be from 35

Measuring waist circumference is arbitrary sometimes. What is the best time to measure it? I have been comparing the reading and found it different between the early morning and evening by 1-2 inches. In the evening, my body is better hydrated, and the effect of the clothes (especially the belt) appears clearly in shaping my waist, giving a bigger reading. I don't know if studies have clarified more about the ideal timing of measurement/

I already eat like a horse and don't regularly do fitness classes or anything so i don't have a clue what I'm meant to do to be considered "healthy"....

I do not understand why so many people are freaking out about their results. In no way is this calculation supposed to be the only measurement needed to calculate lifestyle risk. Try calculating your BMI, your weight, the amount of visceral cavity fat you have, your total fat percentage and you will be able to get a better idea.

By the waist to height ratio I am considered a risk, yet my cholesterol is very low and my blood pressure low. Those say I am in excellent shape yet this ratio indicates I am in a problem mode. I recently had a tread mill test where the Dr said my chances of having a heart attack in the next 7 years was so small it could not be measured. In the end, all we have are a bunch of indicators and that is all they are is indicators but no absolute measurement tied to longevity is available.

However, according to this, any lower than 26" will be in the 'take care' range...so I'm at my ideal waist size for my height! Cool! Great to know that I don't have to feel pressured to lose another inch off my waist, all I need to do is maintain now. Thanks!

This measurement is not perfect either as it doesn't take into account frame size. I have a very small frame and am at a healthy weight for my height, yet this calculator tells me to "take care". I would have to gain almost 4 inches in my waist to be within the "OK" range. In other words, I would be overweight.

The waist to height ratio makes more sense to me. I have a long way to go but maybe I can still make it at my age. I am almost 60 and have a 44" waist. With yoga, I feel that I can accomplish it provided that I stay with a good healthy food and exercise program. Staying motivated has been the struggling point for me.

Just been listening to an article on the radio and found your calculator.

I've always thought that BMI system is flawed and a length to length measurement such as waist to height ratio makes more sense.

Abandon BMI as it becomes less relevant the further you are from average height.

Dividing weight (linked to volume - a 3 dimensional measurement) by height squared (area - 2 dimensional measurement)is flawed.

Comparing two people of similar build 5ft and 6ft tall.

The difference in height squared being being 44% more for the 6 footer yet the difference in volume(weight) is 72.8% more for the 6 footer.

Result a taller person may be classed as overweight or obese compared with a shorter normal BMI individual with exactly the same build.
