I’m not excessively short in stature. Numerous people know, mostly women, are shorter. Still, I’m on the lower end of the adult spectrum. Generally, this doesn’t bother me. I barely notice it unless looking at pictures with tall friends. Or maybe trying to keep up with their long legs on a walk.
In school I remember feeling shocked to learn that some statuesque folks could have disadvantages from height. For instance, taller people suffer greater spinal issues as a rule than their shorter counterparts. Later in my professional life, I observed that regularly.
Nevertheless, I never wanted to be short. Sadly, our stance is not in our control. Worse, recently I came across a self-help test for which I felt a definite disadvantage. It might not exactly affect Aging with Pizzazz. But it may negatively influence quality longevity.
The WHtR Test
To start, I can’t say why a test called the Weight to Height Ratio is not abbreviated as WtHR rather that the accepted WHtR. Perhaps it’s a common nomenclature I missed in science class.
What I can say is that the WHtR is considered better at assessing general health than BMI, or Body Mass Index, so popular in recent decades. We all understand that carrying too much weight is unhealthy, but where we carry it is more revealing of the many jeopardies to our mortality.
Abdominal fat can negatively affect our bodily organs like heart, kidneys, and liver. In turn this adversely increases risks of cardiovascular incidents, hypertension, diabetes and lipid disorders among other ailments.
Occasionally, you will see the WHtR called the Wasit-to-Statue ratio (or WSR). Whether using either term, it’s a measure of fat distribution. Much of the large-scale research on this issue (some noted in the footnotes) which used significantly sizeable cohorts, also appears to confirm an old adage I’ve mentioned on this blog before. A pear shape is healthier than an apple shape figure.
The question emerged “does BMI, measuring general adiposity (fat) in the body evaluate our risks as well as the WHtR assessment.” The answer seems to be no, not really.
WHtR measures “central adiposity” (belly fat) as opposed to overall adiposity in a BMI. Central adiposity does a more thorough job of representing ‘metabolically-active visceral fat’. It’s proposed to be a better predictor of certain obesity-related diseases such as heart disease, stroke, and mortality perils.
The Goal
You may have read elsewhere that the rule-of-thumb for a healthy body is to aim for waist circumference less than half of your height (WHtR less than 0.5). That’s fairly accurate.
For some of us short people that becomes more difficult than it sounds. Further, you might wish to understand where the cutoffs are for different categories. 0.5 isn’t the entire story.
Exact rates of risks for different categories and diseases (lethal diabetes, cardiovascular, etc.) are not the same. Risk to what is known as “all-cause mortally” is a common average. The standard is often reported about 0.58 for men and 0.57 for women. (I’m not including the cutoff rate for children as the literature is less clear, and my personal POV is that they should not go over the higher “slim” level numbers.)
The more moderate the classification (Slim through Healthy in the chart with perhaps a point or two into ‘overweight’) the more likely one is to Age with Pizzazz. The average cutoff values (0.57 and 0.58) refer to mortality risk associated with diseases linked to obesity. We want to stay at – or preferably – below these values.
| WHtR Classification (Weight to Height) Body Status classification |
Adult women | Adult men | Children < 15 years old |
| Extremely slim | ≤ 0.34 | ≤ 0.34 | ≤ 0.34 |
| Slim | 0.35-0.41 | 0.35-0.42 | 0.35-0.45 |
| Healthy | 0.42-0.48 | 0.43-0.52 | 0.46-0.51 |
| Overweight | 0.49-0.53 | 0.53-0.57 | 0.52-0.63 |
| Very overweight | 0.54-0.57 | 0.58.0.62 | — |
| Obese | ≥ 0.58 | ≥ 0.63 | ≥ 0.64 |
Check Yourself
This is a fairly simple self-test. You can do it on your own if you don’t want to share your results, unless you’re afraid you might ‘cheat.’ Here are the few pointers for directions.
- Use a flexible tape measure (or fabric tape measure)
- Find a spot approximately 1 ½-2” above the belly button (specifically between the lowest felt rib and top of your iliac crest.)
- Measuer all around your waist (keeping the tape measure level).
- Use either inches or centimeters for both your height and waist. (For example, you can’t measure waist in centimeters and height in inches.)
- Find the ratio. Divide waist measurement (smaller number) by height.
- Check the chart.

FINAL THOUGHT
You may be disappointed in your ratio. I was too. Still, it may be incentive to either keep things in check or be truly motivated to drop down one category. Progress would also be recognized if you maintain the same weight but morphed from an apple to pear shape. Not sure I know tricks for creating THAT physique change.
“Looks” may no longer be an inspiration for you, but quality aging may be. Perhaps you’re lucky enough to have good genes. That’s a point in your column. Nevertheless, we could all benefit in making sure we don’t rise above the accepted healthy ratios of 0.57 or 0.58. Better yet, aim for that even more salubrious ratio of 50%.
I can confirm that if you aren’t there yet, you aren’t alone. Hopefully, we all think that reducing risks of diabetes, cardio problems, Alzheimer’s, respiratory disease or cancer are encouraging goals.
Then again…maybe “looks” and appearance is indeed your motivation. Go for it.

Quote from site above: “Within the realm of assessing body composition through anthropometric measurements, two prominent metrics have garnered increasing attention: the waist-to-hip ratio (WHR) and, more recently, the waist-to-height ratio (WHtR) [3]. These measurements have risen to prominence as potentially valuable indicators due to their capacity to provide insights into the distribution of body fat and overall health status. Their utilization holds significant promise in both research and clinical settings [4, 5], offering a comprehensive perspective on individuals’ body composition and its potential health risks [6, 7].”
