Body Type Calculator

Find your female body shape from bust, waist, high-hip, and hip measurements — hourglass, spoon, triangle, rectangle, and more — plus waist-hip ratio, in US or metric units.

This calculator estimates a female body shape from bust, waist, high-hip, and hip circumferences, then reports waist-hip ratio. The shape is a fashion category for outfit planning — not a health diagnosis or a target you have to hit. WHR is the more useful health figure of the two.

Fashion nicknames

Shape	Also called
Inverted triangle	Apple
Rectangle	Banana, straight
Triangle or spoon	Pear, spoon, bell
Hourglass	X shape, opposing triangles

Examples

Default 36 in bust, 24 in waist, 32 in high hip, 36 in hip

Bust and hips are equal, and the waist is 12 inches smaller, so the result is Hourglass. Waist-hip ratio is 24 ÷ 36 = 0.67.

36 in bust, 34 in waist, 41 in high hip, 42 in hip

Hips are 6 inches larger than the bust with a high-hip/waist ratio of about 1.21, so both the spoon and triangle rules match: Spoon and Triangle. WHR is 34 ÷ 42 = 0.81.

Formula

All difference cutoffs are in inches. Metric entries convert with 1 in = 2.54 cm, then the same rules run. Matching shapes are listed in this order and joined with "and" when more than one rule fits.

Hourglass          (bust − hips) ≤ 1" AND (hips − bust) < 3.6"
                   AND ((bust − waist) ≥ 9" OR (hips − waist) ≥ 10")
Bottom hourglass   (hips − bust) ≥ 3.6" AND < 10" AND (hips − waist) ≥ 9"
                   AND (high hip / waist) < 1.193
Top hourglass      1" < (bust − hips) < 10" AND (bust − waist) ≥ 9"
Spoon              (hips − bust) > 2" AND (hips − waist) ≥ 7"
                   AND (high hip / waist) ≥ 1.193
Triangle           (hips − bust) ≥ 3.6" AND (hips − waist) < 9"
Inverted triangle  (bust − hips) ≥ 3.6" AND (bust − waist) < 9"
Rectangle          |bust − hips| < 3.6" AND (bust − waist) < 9"
                   AND (hips − waist) < 10"

Waist-hip ratio is waist ÷ hip, rounded to two decimals.

The algorithm is from Lee, Istook, Nam, and Park (2007), International Journal of Clothing Science and Technology. There is a wide size range inside each shape, and some bodies do not match any of the seven.

Measure waist-to-hip ratio separately

For a dedicated ratio calculation with mixed centimeter/inch inputs and measurement guidance, use the Waist-to-Hip Ratio Calculator. Its health-screening measurement protocol is distinct from this page's body-shape classification. Neither a shape label nor a ratio is a medical diagnosis.

Frequently asked questions

What does the Body Type Calculator measure?

It estimates a female fashion body shape from four tape measurements — bust, waist, high hip, and hip — using a seven-category clothing-science algorithm. It also reports waist-hip ratio (WHR), which is a better health signal than the shape name itself.

How should I take the measurements?

Stand straight with arms at your sides. Keep the tape snug, not compressing the skin. Bust is over the fullest part of the breasts in a well-fitted bra. Waist is the smallest circumference at the natural waist, just above the belly button. High hip is the upper swell over the pelvis, about 7 inches (18 cm) below the natural waist. Hip is the largest circumference over the buttocks.

What are the seven body shapes?

Hourglass (bust and hips close, with a defined waist), bottom hourglass, top hourglass, spoon, triangle, inverted triangle, and rectangle. Some measurements match more than one rule and show both names (for example Spoon and Triangle). A few proportions do not fit any category.

Is body shape a health diagnosis?

No. Shape names are fashion categories, not medical advice or an ideal you must meet. Waist-hip ratio is the result to treat more seriously: the WHO threshold used here flags a raw female WHR above 0.85. A rounded display of 0.85 can therefore still trigger the note.

What is a healthy waist-hip ratio?

WHR is waist circumference divided by hip circumference. A 34-inch waist and 40-inch hip is 0.85. The WHO classifies women above 0.85 (and men above 0.90) as having abdominal obesity. This calculator only applies the female threshold.
