What formula does the Body Type Calculator use?

It compares the relative difference between bust and hip, plus how much smaller the waist is than both, using standard percentage thresholds to classify hourglass, pear, apple, rectangle, or inverted triangle shapes.

How accurate is this body shape calculator?

It is a general estimate from a widely used ratio-based formula, not a clinical or medical assessment. Real bodies often fall between categories, so treat the label as a helpful guide rather than an exact classification.

What is waist-to-hip ratio in the Body Type Calculator?

It is your waist measurement divided by your hip measurement (waist / hip). The calculator shows this alongside your body shape since the two figures are commonly used together in fitness and styling contexts.

Why does the apple shape depend on the waist measurement?

Apple shapes are defined by a waist that is as wide as, or wider than, both the bust and hip — so the calculator checks whether waist is the largest of the three measurements before assigning any other shape.

Can I use the Body Type Calculator in inches?

Yes. Switch the unit toggle to US units and enter bust, waist, and hip in inches — the calculator converts everything internally before classifying your shape.

Are my bust, waist and hip measurements uploaded anywhere?

No. The Body Type Calculator runs entirely in your browser. The measurements you enter never leave your device and are not uploaded to ArrayKit. This tool gives a general estimate only and is not medical advice.

About Body Type Calculator

Body Type Calculator estimates your body shape from three simple measurements: bust, waist, and hip. Enter the numbers in metric or US units and the calculator compares the ratios between them to classify your shape as hourglass, pear, apple, rectangle, or inverted triangle, alongside your waist-to-hip ratio. It is useful for choosing flattering clothing cuts, understanding how your proportions change over time, or simply satisfying curiosity about your silhouette. The classification uses a standard ratio-based formula that many stylists and fitness guides reference. This is a general estimate, not a medical or clinical assessment, and it is not medical advice. Everything computes locally in your browser — your measurements stay on your device.

Enter your bust, waist, and hip measurements
Read your body shape and waist-to-hip ratio
Copy the summary or adjust a measurement to see how the shape changes

Example

Input

bust 90, waist 65, hip 92

Output

Shape: Hourglass

A waist that is notably smaller than a similarly sized bust and hip is the hourglass pattern.

Common errors & troubleshooting

The Body Type Calculator shows 'Enter a bust, waist, and hip measurement greater than 0.' — Fill in all three fields with a positive number — the shape formula needs bust, waist, and hip to compare their ratios.
Result looks like the wrong shape for how you see yourself. — Make sure all three measurements use the same unit (all cm or all in) and that the unit toggle matches what you typed — mixing units skews the ratios.
Small changes to one measurement flip the shape between rectangle and hourglass. — This happens when your ratios sit right at a boundary between shapes — both are valid general descriptions of a similar figure, so treat the result as a rough guide rather than an exact label.
The waist-to-hip ratio seems high even though the shape looks like pear. — Waist-to-hip ratio and body shape are related but separate outputs — a pear shape can still have a moderate ratio if the hip measurement is proportionally larger.
