What this calculator classifies
Body-shape labels such as hourglass, triangle, inverted triangle, rectangle and oval describe measurement proportions, not health, attractiveness or fitness. This calculator compares shoulders, bust, waist and hips using simple percentage thresholds.
The result is designed for clothing and proportion reference. It does not estimate body fat, medical risk or a “best” body shape.
Measurement consistency matters
Use the same measuring tape and unit for all fields. Measure around the fullest bust or chest, natural waist and fullest hip area. For shoulders, use a consistent circumference-style measurement around the broadest shoulder line if possible.
Because body-shape systems use different definitions, a person near a boundary can reasonably fit more than one label. The calculator therefore shows waist-to-bust, waist-to-hip and bust-to-hip ratios alongside the category.
Use labels lightly
Body proportions can change with posture, clothing, muscle development and measurement technique. Labels are only shorthand for pattern proportions.
For clothing, garment measurements and fit notes are often more useful than a general body-type label, especially across different brands and styles.
Important information
This calculator is for general education and planning. It is not a diagnosis, medical device or substitute for individualized healthcare advice. Measurements and formula estimates can differ from clinical assessments.
If the result could affect treatment, pregnancy care, medication, driving, military status or another safety-sensitive decision, confirm it with the appropriate qualified professional or official process.
Frequently Asked Questions
Does body type tell me whether I am healthy?
No. This calculator only describes relative measurements.
Why can two calculators give different body-shape labels?
Different systems use different thresholds and may emphasize shoulders, bust or hips differently.
Can I use inches?
Yes. Ratios are unit-independent as long as every measurement uses the same unit.
