This body type calculator (also called a body shape calculator) works out your body shape from four tape measurements — bust or chest, natural waist, high hip and full hip — and then shows its working. It does not just print a label: it evaluates all seven published shape rules independently, tells you exactly which conditions passed and which failed, measures how far you sit from every boundary, and reports whether a one-centimetre difference in how you held the tape would have changed the answer. When two rules are both satisfied it says so instead of picking one, and when none of them is satisfied it says that too, rather than falling back on a default category.

Enter a height to see the adult healthy-BMI reference range, the exact weight at any target BMI inside it, and how five historical ideal body weight formulas compare — with waist-to-height ratio as an optional extra check.

This calculator estimates lean body mass (LBM) — the part of your body weight that is not fat — from height, weight and sex. Lean body weight is the closely related term used in pharmacology and imaging, and one of the four equations here reports its result under that name. Because no single equation is agreed on, Boer, James, Hume and Janmahasatian are computed side by side, the gap between them is measured, and the arithmetic behind each one can be opened and checked. Lean body mass is not the same as muscle mass: skeletal muscle is only one component of the lean compartment.

This bra size calculator turns two tape measurements into a starting bra size in six sizing systems, tells you how much your own readings and the documented methods disagree, checks whether the bra you already own actually fits, shows sister sizes and international equivalents, and prints the whole calculation so you can check it.
