Waist Size Chart for Women: Healthy Measurements by Height

For adults, a simple waist-to-height target is to keep your waist below half your height. For example, at 160 cm (5'3"), that corresponds to about 80 cm (31.5 in); at 170 cm (5'7"), about 85 cm (33.5 in). The chart below shows the numbers by height and also explains how they compare with commonly used fixed waist-circumference thresholds.

Unlike BMI, waist circumference provides information about abdominal fat distribution, which is associated with cardiometabolic risk including insulin resistance and cardiovascular disease.

Average waist size vs. target waist size

A lot of people searching for a waist size chart are really asking what's average — but average isn't the same question as target, and it's worth keeping the two apart. Recent CDC data [3] puts the average waist circumference for adult women in the US at 38.5 in (97.9 cm).

Quick facts

Average U.S. adult woman: 38.5 in (97.9 cm) waist

This is a population average, not a recommended target. [3]

If your waist is close to the population average, you may still be well above your personal target — especially if you're on the shorter side. A rising average simply reflects where most people currently are, not where it's healthiest to be.

Common waist thresholds: 80 cm and 88 cm

Traditional waist-circumference guidelines use fixed sex-specific thresholds. For women, 80 cm (31.5 in) and 88 cm (about 35 in) are commonly used risk thresholds [4]: 80 cm is associated with increased health risk, and 88 cm with substantially increased risk. In the US, a waist above 35 inches (about 88 cm) is similarly cited as a risk marker for women [5]. These are useful screening cutoffs, but because they do not account for height, waist-to-height ratio offers an additional way to put your measurement in context. Our healthy waist size calculator is built around this exact idea.

Why height matters: the waist-to-height ratio (WHtR) method

WHtR is simply your waist circumference divided by your height. A 2010 systematic review by Browning, Hsieh, and Ashwell covering 78 studies [1] found WHtR to be a useful screening measure for diabetes and cardiovascular risk, and concluded that 0.5 could be a suitable global boundary value. A 2014 actuarial validation by Ashwell [2] supported the same boundary in large, diverse populations. Guidelines vary in how finely they categorize WHtR: NICE, for example, treats 0.4–0.49 as a healthy range, 0.5–0.59 as increased central adiposity, and 0.6 and above as high central adiposity [6] — broadly consistent with the target, increased, and high-risk zones used throughout this page. You can run the full calculation any time with the waist-to-height ratio calculator.

The table below shows how the fixed 88 cm (34.5 in) threshold compares with the height-adjusted target from waist-to-height ratio:

Height Fixed threshold
(88 cm / 34.5 in)
Height-adjusted target
(WHtR < 0.5)
Difference
150 cm (4'11")88 cm (34.5 in)< 75 cm (29.5 in)WHtR threshold is 13 cm (5 in) lower
160 cm (5'3")88 cm (34.5 in)< 80 cm (31.5 in)WHtR threshold is 8 cm (3 in) lower
170 cm (5'7")88 cm (34.5 in)< 85 cm (33.5 in)WHtR threshold is 3 cm (1 in) lower
180 cm (5'11")88 cm (34.5 in)< 90 cm (35.5 in)WHtR threshold is 2 cm (1 in) higher
190 cm (6'3")88 cm (34.5 in)< 95 cm (37.5 in)WHtR threshold is 7 cm (3 in) higher

The two methods can classify the same waist measurement differently, especially at shorter or taller heights. WHtR adds height to the calculation, while fixed waist-circumference thresholds use the same cutoff within each sex.

Waist-to-height ratio infographic comparing a healthy waist (170 cm height, 80 cm waist, WHtR 0.47, lower estimated risk) to a high-risk waist (170 cm height, 108 cm waist, WHtR 0.64, higher estimated risk), with WHtR risk zone key: below 0.50 lower risk, 0.50–0.59 elevated risk, 0.60 and above high risk
A waist under half your height sits in the target zone. A waist at 60% or more of your height sits in the high-risk zone.

How to measure your waist correctly

How to measure your waist correctly for women — 6 steps: find your lowest rib, find the top of your hip bone, measure at the midpoint, exhale normally, keep the tape snug, measure twice and average

Find the midpoint between your lowest rib and the top of your hip bone (iliac crest) — usually a couple of centimeters above the navel, not the narrowest point of your torso and not the navel itself. Stand upright, breathe out normally without pulling your stomach in, and wrap the tape horizontally around your body, snug against the skin but not compressing it. Measure in the morning before eating for the most consistent results, and take it over bare skin or a single thin layer rather than over clothing.

Waist size and hormonal changes in women

Fat distribution isn't static across a woman's life. Body-fat distribution often changes through midlife and menopause, with many women experiencing greater abdominal fat accumulation, sometimes without a large change in overall weight or BMI. This is one reason waist measurement is a particularly useful number for women to track through midlife: the scale and BMI can both stay flat while central fat quietly increases.

Waist size can also fluctuate around pregnancy, postpartum recovery, and hormonal conditions like PCOS, which is independently associated with central fat accumulation. None of this changes the underlying target — WHtR below 0.5 — but it's worth remeasuring periodically rather than relying on a single measurement taken years ago.

What if your waist is above your target range?

A waist above your target range is a signal worth paying attention to, not a diagnosis. It means your statistical risk for cardiometabolic issues may be elevated — it doesn't mean anything is currently wrong. If your waist measurement is elevated or you have other metabolic risk factors, consider discussing it with a healthcare professional. They may recommend tests such as fasting glucose, HbA1c, triglycerides, or HDL cholesterol depending on your individual risk profile.

Small changes matter. Reductions in waist circumference often accompany improvements in cardiometabolic health, so progress can still matter even before you cross a particular threshold. You don't need to reach the target in one move — any reduction toward it is beneficial.

Frequently asked questions

What is a healthy waist size for a woman?
It depends on your height. A commonly used target is to keep your waist below half your height (a WHtR under 0.5). For an average-height woman around 163 cm (5'4"), that's roughly 81.5 cm (32 in). A shorter woman's target is lower; a taller woman's is higher. Use the calculator above for your exact number.
Is a 35-inch (88 cm) waist too big for a woman?
A 35-inch (88 cm) waist is a commonly used risk threshold for women, based on WHO and NIH guidance. Height adds useful context: WHtR classifies 88 cm differently depending on how tall you are — at 160 cm, 88 cm gives a WHtR of about 0.55 (increased); at 180 cm, it gives about 0.49 (within the target range). WHtR doesn't replace the fixed threshold, it adds another way to interpret the same measurement.
Why isn't the healthy waist size the same for every woman?
Taller people have proportionally larger frames, including more torso length, so a larger waist measurement doesn't automatically mean more central fat. Waist-to-height ratio (WHtR) divides waist by height to correct for this, which is why the target scales up with height instead of staying fixed.
Does a healthy waist size change after menopause?
The WHtR target itself doesn't change, but body-fat distribution often shifts toward the abdomen through midlife and menopause, even without a large change in weight. This makes waist measurement a particularly useful number to track through perimenopause and beyond, since BMI or the scale alone can miss this shift entirely.
Is this chart different from a waist-to-hip ratio chart?
Yes. Waist-to-hip ratio compares waist to hip circumference and uses different cutoffs for men and women. This chart uses waist-to-height ratio (WHtR), which compares waist to height. WHtR uses the same broad adult thresholds for men and women in guidelines such as NICE, although it remains a screening measure rather than a diagnosis.
