Body Shape Calculator

What these shape categories mean (and don't)

Apple, pear, hourglass, and rectangle are popular, informal descriptions of where someone tends to carry proportion between bust/chest, waist, and hips — not a medical classification, a fitness level, or a body type with a fixed diet or training prescription attached.

The calculator compares the three measurements: a small waist relative to similar bust and hip measurements tends to read as an hourglass shape; hips noticeably larger than both bust and waist reads as pear; a waist close to or larger than the hips reads as apple; and measurements that are all fairly close together read as rectangle.

Waist-to-hip ratio (shown alongside the shape estimate) is a separate, more widely used measurement in health research, generally referenced by dividing waist circumference by hip circumference — run it through the full waist-to-hip ratio calculator if you want a risk-category read on that number specifically, or the BMI calculator and body fat calculator for other angles on body composition.

This tool gives a rough, non-judgmental estimate for anyone curious about the popular shape categories. It isn't diagnostic, doesn't measure body fat percentage or fitness, and shouldn't be used to justify a particular diet, training plan, or body-image conclusion.

Where these numbers come from

The formulas and default values in this calculator are based on:

• Common popular body-shape classification schemes (apple/pear/hourglass/rectangle) widely referenced in fashion and fitness media
• waist-to-hip ratio methodology from general health research conventions

These are planning estimates for training purposes. Check with a coach, trainer, or physician before starting a new program or maxing out.
