Body Shape Calculator US
Find your body shape — hourglass, pear, inverted triangle or rectangle — from your bust, waist and hip measurements.
Enter all three using the same unit (cm or inches).
General estimate using standard formulas — not medical or dietary advice. For personalised guidance, speak to a qualified professional.
How it works
Enter your bust, waist and hip measurements using the same unit for all three. The calculator compares the proportions and classifies your shape as hourglass, pear (triangle), inverted triangle (apple) or rectangle, and shows your waist-to-hip ratio.
Frequently asked questions
How is body shape determined?
By comparing bust, waist and hip measurements — and sometimes the waist-to-hip ratio — to assign a descriptive type like rectangle, pear, apple or hourglass.
What is waist-to-hip ratio?
Your waist measurement divided by your hip measurement. It is used both for describing shape and, separately, in some health screening.
What are the common body-shape types?
Often rectangle, pear (triangle), apple (inverted triangle) and hourglass, based on the relative proportions of bust, waist and hips.
Is one body shape healthier than another?
Shape itself is natural variation. Some research links where fat is stored, especially around the waist, to health risk at a population level.
What is body shape used for?
Most commonly for clothing fit and styling, helping choose cuts that suit your proportions.
Does this assess my health?
No. It is for general and styling information. For health questions about weight or waist size, consult a healthcare professional.
How body shape is categorised
A body-shape calculator groups your figure into a descriptive type — such as rectangle, pear, apple or hourglass — based on the relative sizes of your bust, waist and hips. It is most often used for clothing fit and styling, and it describes natural variation rather than anything better or worse.
Measurements used
The tool compares your bust, waist and hip measurements, and may use the waist-to-hip ratio (waist ÷ hips). For example, similar bust and hip measurements with a clearly narrower waist is often described as an hourglass, while fairly even measurements are described as a rectangle.
Shape and health
Separately from styling, research links where the body stores fat — particularly around the waist — to certain health risks, which is why waist measurement and waist-to-hip ratio are sometimes used in health screening. This is a general association across populations, not a judgment about any individual.
Body shape is a normal part of human variation and is not a measure of worth or attractiveness. For any health questions related to weight or waist size, a healthcare professional can give guidance suited to you; this tool is for general and styling information only.
