Most body shape quizzes ask you to eyeball a silhouette and guess. This body type calculator skips the guesswork and works from your actual bust, waist, and hip measurements to tell you which shape category you fall into, along with your waist-to-hip ratio, waist-to-height ratio, and an estimate of your frame size. Enter a handful of numbers and it does the comparing for you.
How to use this body type calculator
- Choose your unit system: Metric (cm/kg) or Imperial (in/lb).
- Select your sex: Female or Male.
- Enter your bust or chest measurement.
- Enter your waist measurement.
- Enter your hips measurement.
- Optionally add your high hip measurement (measured a few inches below the belly button, over the hip bones).
- Optionally add your height.
- Optionally add your shoulder measurement.
- Enter your wrist circumference, measured just below the wrist bone on your dominant hand, which the calculator uses to estimate frame size.
- Optionally add your weight.
- Click “Find my body type” to run the calculation.
- Review your results: body type, waist-to-hip ratio (WHR), waist-to-height ratio, bust vs hips comparison, waist definition, frame size, and somatotype tendency.
- Use “PDF report”, “Share”, “Copy report”, or the Export Excel/PDF/CSV buttons to save or send your results, or “Clear all” to start over.
What this body type calculator does
The calculator compares the relationships between your bust (or chest), waist, hips, and, if you provide them, your high hip and shoulder measurements. Rather than matching you to a single fixed shape based on one number, it looks at the ratios and differences between these measurements to work out which classification best describes your proportions. The more optional fields you fill in (high hip, height, shoulders, weight), the more detail the output gives you, but bust, waist, hips, and wrist are the core numbers it needs to produce a result.
Alongside the shape category, the tool also calculates your waist-to-hip ratio and waist-to-height ratio, both of which are simple proportion checks used widely in fitness and health tracking, and a frame size estimate based on your wrist circumference. It also gives a “somatotype tendency” reading, a rough indication of build tendency rather than a strict classification.
How the body type calculator sorts your shape
This body type calculator uses the differences between your bust, waist, and hip figures (and high hip, where entered) to sort you into one of nine descriptive shape categories. None of these categories is better or worse than another; the page itself is upfront about this, noting that “body shapes are descriptive proportions, not grades” and that every shape is normal.
| Body shape |
How it’s defined |
| Hourglass |
Bust is roughly equal to hips, with a clearly defined waist |
| Top hourglass |
Bust a little larger than hips, waist still defined |
| Bottom hourglass |
Hips a little larger than bust, waist still defined |
| Spoon |
Hips larger than bust, with a pronounced high-hip “shelf” |
| Triangle (pear) |
Hips clearly larger than bust, with a gentler waist definition |
| Inverted triangle |
Bust or shoulders clearly larger than hips |
| Rectangle |
Bust, waist, and hips are roughly equal, with a straighter waistline |
| Trapezoid |
Chest and shoulders taper clearly to the waist, with balanced hips |
| Oval |
Waist is the widest point on the body |
Waist-to-hip ratio and waist-to-height ratio
These two figures are shown alongside your body type result. The waist-to-hip ratio is your waist measurement divided by your hip measurement, and the waist-to-height ratio is your waist measurement divided by your height (which is why height is worth filling in even though it’s optional). Both are simple proportion checks rather than diagnostic tools, and the calculator treats them as general screening indicators, not a medical result.
Waist-to-hip ratio = Waist ÷ Hips
Waist-to-height ratio = Waist ÷ Height
Frame size from your wrist
Frame size is worked out from your wrist circumference, measured just below the wrist bone on your dominant hand. This isn’t related to your body shape category directly; it’s a separate estimate of whether your skeletal frame reads as small, medium, or large, which is useful context alongside your shape result.
Optional fields and why they matter
High hip, height, shoulders, and weight are all optional in this body type calculator, but each one sharpens the result. High hip helps distinguish shapes like Spoon, which depend on a hip “shelf” a few inches below the belly button rather than at the widest point of the hips. Shoulders help separate Inverted triangle and Trapezoid results, since both involve a wider upper body but taper differently. Skipping these fields still gives you a body type, waist-to-hip ratio, and frame size, just with slightly less nuance in the shape classification.
Reading your results without overthinking them
It’s worth remembering what this calculator is and isn’t. It’s a measurement comparison tool, not a fitness or medical assessment. The waist-to-hip and waist-to-height ratios it produces are general screening numbers, and the body shape label is descriptive rather than evaluative. If you use it more than once, the history table (with time, mode, result, and WHR columns) lets you track how your measurements and shape reading change over time, and you can export any entry to Excel, PDF, or CSV.
Whether you’re curious about your proportions for clothes shopping, tracking measurement changes over months, or just want a number to go with what you already suspected about your shape, this body type calculator gives you a quick, measurement-based answer instead of a guess from a chart.
Frequently asked questions
What measurements do I need for the body type calculator?
At minimum, you need your bust or chest, waist, hips, and wrist circumference. High hip, height, shoulders, and weight are optional but improve the accuracy of the shape category and give you the waist-to-height ratio.
Does the body type calculator work differently for men and women?
You select your sex (Female or Male) before entering measurements, since the calculator uses this along with your bust/chest, waist, and hip figures to determine your shape category, waist-to-hip ratio, and frame size.
Is one body shape category better than another?
No. The calculator’s own guidance is clear that body shapes are descriptive proportions, not grades, and that every shape it lists, from hourglass to rectangle to oval, is normal. The categories exist to describe proportion patterns, not to rank them.
How do I measure my wrist for the frame size result?
Measure your wrist circumference just below the wrist bone on your dominant hand. This number feeds into the frame size estimate shown alongside your body type, waist-to-hip ratio, and other results.
