Attractive Waist to Hip Ratio: What Research Actually Shows

Last updated: June 2026

The idea that a specific waist-to-hip ratio is universally attractive sounds like the kind of claim that wouldn’t survive scientific scrutiny. In practice, it has — at least partially. Since the early 1990s, evolutionary psychologists, anthropologists, and behavioural researchers have run hundreds of studies on WHR attractiveness across cultures, and the evidence consistently points to a relatively narrow range as most preferred. The reasons, the caveats, and the specific numbers are more nuanced than most summaries suggest.

The Classic Finding: Singh 1993

The foundational study in this area is Devendra Singh’s 1993 paper in the Journal of Personality and Social Psychology. Singh presented male participants with drawings of female figures varying in WHR and asked them to rate attractiveness. The consistent finding: women with a WHR of approximately 0.7 were rated most attractive. WHRs below 0.65 and above 0.80 were rated significantly less attractive.

Singh’s interpretation was evolutionary: a WHR around 0.7 signals both adequate fat stores (fertility) and low abdominal fat (health and non-pregnancy status). The shape itself — a defined waist relative to broader hips — is a secondary sex characteristic that appears at puberty and declines with age and menopause, making it a potential cue to reproductive age and health.

Subsequent Research: Refinements and Challenges

Singh’s 0.7 finding has been tested, replicated, challenged, and refined across several decades of follow-up research. The picture is more complex than a single number:

The preferred range is broader than 0.7

Karol Kościński’s 2013 study, published in Archives of Sexual Behavior, asked participants to rate computer-generated female torsos across a wider range of WHRs. The result: attractiveness ratings were highest for WHRs in the 0.65–0.75 range, with the peak often around 0.68–0.70. Values below 0.65 and above 0.80 showed sharp drops in ratings. The 0.7 figure held as a rough centre of the preferred range, but the band was wider than Singh’s original framing implied.

Very low WHR is not the most attractive

A consistent finding across studies — and one that surprises many people — is that a very low WHR (below 0.65) does not attract higher ratings than 0.70. Lassek and Gaulin’s research found that intermediate values in the 0.67–0.75 range were consistently preferred over extreme values in either direction. The attractiveness function is an inverted U, not a monotonic decline — getting the waist as small as possible relative to hips is not the goal.

Men’s actual preferences cluster around 0.65–0.75

Survey data from the fitness and coaching community (including Bony to Bombshell’s survey of over 1,000 men asked to rate female figures) consistently find the most attractive range is 0.65–0.75, aligning closely with the lab research. Men in these surveys typically rate a 0.7 figure as clearly more attractive than either 0.6 or 0.8 figures.

Cultural and Historical Variation

One of the most interesting complications to the “universal 0.7” narrative comes from cross-cultural and historical data. Bovet and Raymond’s work analysing depictions of female beauty across different historical periods found that the preferred WHR has not been constant. Their analysis of artwork and sculpture across cultures found preferences ranging from approximately 0.74 in ancient depictions to around 0.68 in contemporary Western contexts — a shift that suggests the preference is partly culturally mediated, not purely hard-wired.

Cross-cultural field studies — including research with populations in rural Tanzania, Peru, and Cameroon — found that preferences for WHR varied substantially across populations. In some non-Western populations, higher WHRs were rated as more attractive than in Western samples, and in some populations body weight carried more salience than WHR in attractiveness judgments.

The most defensible conclusion: there is a real biological signal in the 0.65–0.75 range for women, but cultural exposure, media, and local norms shift where within that range people find most appealing — and in some contexts, shift preferences outside that range entirely.

What This Means for Men

Research on male WHR attractiveness is substantially less developed. Studies on male figure attractiveness find that women generally prefer men with a V-shaped torso — broad shoulders, narrower waist — which in WHR terms corresponds roughly to a WHR around 0.85–0.95 in men (compared to the WHO health threshold of 0.90 for men).

A 2004 study found women rated male figures with WHR around 0.90 as most attractive, with ratings declining for both higher and lower values. Unlike the female data, male WHR preferences in women vary more with context and personal preference — muscularity, height, and shoulder-to-waist ratio (SWR) are often more salient attractiveness cues than WHR in men.

Does Attractive WHR Overlap with Healthy WHR?

The overlap is significant, which is likely not a coincidence. The WHO defines elevated health risk for women above WHR 0.85. The range rated most attractive in research (0.65–0.75) sits comfortably below this threshold. A WHR of 0.70 is both the approximate peak of attractiveness ratings in Western research and a number associated with low cardiometabolic risk in health data.

Lassek and Gaulin explicitly tested this in their research, finding that the WHR values rated most attractive by men also correlated with better health outcomes in women — lower waist circumference (less abdominal fat), better cognitive test scores, and lower chronic disease risk. Their interpretation was that the attractiveness signal is partly functional: a defined waist at a healthy weight is visible evidence of good metabolic health.

However, the health-attractiveness overlap is not perfect. A very lean woman with minimal hip fat may have a WHR in the 0.60–0.65 range — which is associated with lower attractiveness ratings in research but is not a health concern. And an athletic woman with large glutes from strength training may have a naturally low WHR that reflects muscle rather than fat distribution.

Summary of Research Findings

The Limits of WHR as an Attractiveness Metric

WHR is one variable in attractiveness, not a complete formula. Research consistently finds that body weight (or body fat percentage), facial features, height, and personality all carry independent weight in how attractive people find each other. Studies that control for body weight often find the WHR effect weakens or disappears — suggesting that in many contexts, people are responding to overall body composition rather than the ratio specifically.

The practical takeaway from the research is not “achieve a 0.70 WHR and you’ll be maximally attractive.” It is that a defined waist relative to hips — at a healthy body weight and fat percentage — is a reliable attractiveness cue across many cultural contexts. Chasing a specific number as a target misses the underlying biology: a WHR in the preferred range at a healthy weight is a byproduct of low abdominal fat and adequate hip and thigh mass, not something optimised directly.
