π― Body Shape Calculator
Apple, pear, hourglass, rectangle, or inverted triangle from your measurements.
A simplified classification for education and clothing fit, not a medical assessment.
Your body shape is just a description of where your measurements are widest: bust, waist, or hips. Enter the three numbers and this calculator classifies you as apple, pear, hourglass, rectangle, or inverted triangle, then explains what the shape implies for health risk and for clothes that actually fit. It is geometry, not judgment.
How to Use This Calculator
Measure bust, waist, and hips with a soft tape, add shoulders if you have them, and read your shape.
Measure bust at the fullest point, waist at the narrowest (or navel if no clear narrowest), and hips at the widest point. Keep the tape level.
Enter the numbers in inches. Shoulders are optional but sharpen the inverted-triangle call.
Read your shape and the waist-to-hip ratio. The ratio matters more for health; the shape matters more for the fitting room.
The Five Shapes and the Rules
These are simplified classification rules, not a medical taxonomy. Real bodies blend categories, and the boundaries are conventions from the apparel industry, which needed them for sizing long before the internet needed them for quizzes. The health-relevant signal inside the shape is really the waist: apple shapes carry more visceral fat, which is the fat most tied to metabolic risk. Pear shapes store more subcutaneous fat around hips and thighs, which is comparatively benign.
That distinction is worth more than the label. Two women can both be pears with the same hip measurement while one has a 28-inch waist and the other a 36-inch waist, and their health pictures differ enormously. So take the shape for fun and for shopping, and take the waist-to-hip ratio seriously.
Worked Example
Bust 36, waist 30, hips 40. Hips exceed bust by 4 inches and the waist sits 10 inches below the hips: pear. Waist-to-hip ratio is 0.75, comfortably under the 0.85 threshold where risk rises for women. Now change only the waist to 38: waist is now the widest measurement, so the classification flips to apple, and the waist-to-hip ratio jumps to 0.95. Same hips, same bust, completely different risk picture. The eight-inch waist swing moved everything that matters while the label just followed along.
What Your Shape Means for Health
Apple shapes deserve the most attention: central fat tracks with insulin resistance, higher triglycerides, and cardiovascular risk even at the same BMI as other shapes. If you are an apple, your waist-to-height ratio is the number to watch, and getting the waist under half your height is the goal that actually moves risk. Pear shapes get the better metabolic deal but are not exempt: overall body fat still matters, and hip fat is benign only relative to belly fat, not absolutely.
Hourglass, rectangle, and inverted triangle are mostly neutral for health; the waist number still rules. Muscle changes the reading too: a lifter with a thick waist from obliques and a small waist-to-hip ratio is not an apple in any meaningful sense. Shapes describe silhouettes. Risk lives in the waistline and the blood work.
Dressing Your Shape Without the Nonsense
The practical half of body shape is fit. Pears usually size up for hips and tailor the waist. Apples look for structure through the midsection and defined shoulders. Hourglasses need waist definition or everything boxes out. Rectangles create curves with belts and layering. Inverted triangles balance with volume below the waist. None of this is a rulebook, just pattern recognition from how fabric falls on geometry. Knowing your numbers beats knowing your label: bring bust, waist, and hips to any tailor and the shape sorts itself out.

Frequently Asked Questions
What are the 5 body shapes?
Apple (waist widest), pear (hips widest), hourglass (bust and hips balanced, waist defined), rectangle (all measurements close), and inverted triangle (bust/shoulders widest). This calculator assigns one from your bust, waist, and hip measurements.
How do I measure my body shape?
With a soft tape: bust at the fullest point, waist at the narrowest point, hips at the widest point. Keep the tape level and snug, not tight. Enter the three numbers above and the calculator classifies your shape from the differences between them.
Which body shape is healthiest?
The label matters less than the waist. Pear shapes tend to carry lower metabolic risk than apple shapes at the same weight, because hip fat is less harmful than belly fat. But a pear with a large waist still carries risk, so watch waist-to-hip ratio rather than the shape name.
Can your body shape change?
Partially. Fat loss and gain redistribute somewhat, and training changes proportions: lats and shoulders can build an inverted triangle, glute training fills out a pear. Bone structure does not change, so rectangles rarely become hourglasses through anything but weight change.
What is the difference between apple and pear shape?
Apples carry weight around the midsection with the waist as the widest point; pears carry it around hips and thighs with the hips widest. The distinction matters because abdominal fat is more strongly linked to metabolic disease than lower-body fat.
Is waist-to-hip ratio more important than body shape?
Yes, for health. Waist-to-hip ratio is a validated risk marker: above 0.90 for men and 0.85 for women signals raised risk regardless of shape label. Body shape is more useful for clothing fit than for health assessment.
What body shape do men have?
Men mostly fall into rectangle, inverted triangle (athletic builds), or apple (central weight gain). The same measurement rules apply using chest instead of bust. Male health risk follows the same waist-driven pattern.
I am between two shapes. Which am I?
Most people are. The categories have hard cutoffs but bodies do not, so landing near a boundary just means you share traits of both. Use the shape for shopping guidance and ignore the label for everything else.
Does body shape affect what clothes fit?
Enormously, which is why the apparel industry invented the categories. Knowing your shape predicts where off-the-rack clothing will pull, gap, or box out, and which alterations are worth paying for. A tailor works from your three numbers, not your label.
Can exercise change an apple shape?
It can shrink the waist and build shoulders and glutes, which visually rebalances the silhouette, but spot reduction is a myth: you cannot crunch away belly fat specifically. Overall fat loss plus muscle building is the only real lever.
