Start with the number you need. Measure waist and hips, read the ratio against the published thresholds, or go straight to the shape classification — each guide links back to the calculator so you can check the arithmetic with your own tape.
Landmarks, tape tension, breathing and the five mistakes that shift the ratio.
WHO thresholds for women and men, with worked examples in cm and inches.
The 0.85 and 0.90 cutoffs, what age changes, and why waist circumference matters too.
The placement and tension the U.S. Navy body fat formula expects.
Use chest, waist and hip measurements to identify hourglass, pear, apple, rectangle or inverted triangle shape — the exact ratios and worked examples.
No tape? Use a mirror, a fitted top and a photo to estimate your body shape — plus when a visual guess is good enough and when to measure.
Body shape is a ratio of chest, waist and hip; body type also covers frame, fat distribution and fitness. Here is how the terms differ — and why it matters.
WHO waist-to-hip ratio charts for women and men, with healthy ranges, risk thresholds and worked examples in cm and inches.
What counts as a healthy waist-to-hip ratio for women and men, how age affects the reading, and why 0.85 and 0.90 are the numbers to know.
Step-by-step waist and hip measurement at home: landmark, tape level, breathing, clothing and the five mistakes that shift the ratio.
The U.S. Navy body fat formula starts with a neck measurement. Where to place the tape, how tight, common errors and what changes the result.
The U.S. Navy circumference equations for men and women, a worked example, accuracy versus DEXA and when the estimate stops being useful.
Apple shapes store more fat around the waist; pear shapes around the hips. Compare measurements, health signals and styling logic — without the stigma.
Both have wider hips than shoulders, but the waist ratio separates them. Compare measurements, silhouettes and what each shape needs from clothing.
One has a clearly wider chest and shoulders; the other has little waist definition. Use chest, waist and hip ratios to tell which shape you have.
Weight loss, strength training and posture can change measurements and proportions — but not your bone structure. What is realistic at each stage.
These guides describe proportion and measurement. They are editorial references, not medical advice. For health decisions, discuss waist circumference, blood pressure, glucose and lipids with a clinician.
