Body Shape Calculator

A Body Shape Calculator is a useful online tool that helps you determine your body type based on measurements such as bust, waist, hips, and shoulders. By analyzing these proportions, the calculator identifies common body shapes like pear, apple, rectangle, or hourglass, giving you a better understanding of your natural physique.

In short

Your body shape comes from bust, waist and hip ratios: bust ≈ hips with a defined waist is hourglass; hips wider is pear; bust wider is inverted triangle; similar widths is rectangle; a waist as wide as bust and hips is apple.

How it works

Body shape is a comparison of three measurements — bust, waist and hips — not a judgement about size. The calculator compares them and names the common shape that fits.

  1. Measure the bust at the fullest point, the waist at its narrowest and the hips at the widest, keeping the tape level.
  2. The calculator compares the three numbers.
  3. It returns the closest of the standard shapes.
How the shapes are defined
ShapePattern
HourglassBust and hips within about 5%, waist at least 25% smaller
Pear (triangle)Hips larger than bust by more than 5%
Apple (round)Waist larger than bust and hips
RectangleAll three within about 5% of each other
Inverted triangleBust larger than hips by more than 5%

Shape is useful for choosing clothes that fit without alteration. It says nothing about health — for that, waist measurement and body fat percentage are the numbers that matter.

Examples

Worked examples:

  • 36-26-37 inches: bust and hips close, waist 28% smaller — hourglass.
  • 34-28-40: hips 18% larger than bust — pear.
  • 36-34-35: all three within 5% — rectangle.
