What is a body type calculator?

A body type calculator takes your bust, waist, high hip and hip measurements and works out which body shape your proportions match, such as hourglass, pear, apple, rectangle or inverted triangle. This one is free, runs entirely in your browser, and pairs each result with practical styling guidance rather than any judgement about health or size.

What body types does this calculator use?

Women's results follow the seven-shape FFIT method — hourglass, top hourglass, bottom hourglass, spoon, triangle (pear), inverted triangle and rectangle — plus a round/apple reading when the waist is the widest point. Men use trapezoid, rectangle, oval, triangle and inverted triangle.

How is my body type calculated?

The calculator compares your bust, waist, high hip and hips in inches against published FFIT thresholds. A defined waist with balanced top and bottom reads hourglass, a fuller lower body reads triangle, spoon or bottom hourglass depending on the high hip, a broader upper body reads top hourglass or inverted triangle, a full midsection reads apple, and closely matched numbers read rectangle.

Why does the high hip measurement matter?

The ratio of high hip to waist separates a spoon shape, which has a pronounced upper-hip shelf, from a bottom hourglass or a plain triangle. Entering your real high-hip number makes those close calls accurate.

Is the hourglass the ideal shape?

No. In a study of more than 6,000 women the hourglass was the least common result at about 8 percent. The shapes are fit categories, not a ranking or an ideal.

What is waist-to-hip ratio?

Waist-to-hip ratio is waist divided by hips. Unlike body shape it is used as a rough population-level health indicator, shown with reference bands from the WHO and NIDDK, but it cannot diagnose anything on its own.

Can body type change over time?

Your underlying frame is fairly stable, but visible proportions can shift with training, age, hormones, pregnancy or weight change. Remeasure if clothing fit starts to feel different.

Compare all shapes

This is style and fit guidance only. Body shapes describe proportion, not health, worth, or an ideal to reach for. Every shape is complete as it is.

The lookbook

Every silhouette, explained

These are proportion groups, not rankings. The women's set follows the seven-shape method plus a round/apple reading; the men's set covers five common frames. The only question any of them answers: where does a garment need room, and where can it follow your line?

The numbers

How common is each shape?

A study of more than 6,000 US women at North Carolina State University sorted real bodies into shape groups. It's a useful reality check: the hourglass so often shown as default is actually the rarest result.

Read this loosely. These proportions describe one population at one point in time. Distributions shift with age, region, genetics and the measuring method, and many bodies sit between categories or fit none cleanly. The takeaway isn't a target — it's that every shape, including the most common ones, is entirely ordinary.

Under the hood

The method, in the open

Women's shapes use the FFIT (Female Figure Identification Technique) rules from a peer-reviewed clothing-science study. The calculator compares your bust, waist, high hip and hips against these thresholds, in inches, in this order. No black box.

Hourglass

(bust − hips) ≤ 1 and (hips − bust) < 3.6 and (bust − waist ≥ 9 or hips − waist ≥ 10)

Top hourglass

(bust − hips) > 1 and (bust − hips) < 10 and (bust − waist) ≥ 9

Bottom hourglass

(hips − bust) ≥ 3.6 and (hips − bust) < 10 and (hips − waist) ≥ 9 and (high hip ÷ waist) < 1.193

Spoon

(hips − bust) > 2 and (hips − waist) ≥ 7 and (high hip ÷ waist) ≥ 1.193

Triangle (Pear)

(hips − bust) ≥ 3.6 and (hips − waist) < 9

Inverted triangle

(bust − hips) ≥ 3.6 and (bust − waist) < 9

Rectangle

|bust − hips| < 3.6 and (bust − waist) < 9 and (hips − waist) < 10

Apple (Round)

waist ≥ bust or waist ≥ hips — the waist reads as the widest point

Seven-shape logic adapted from Lee, Istook, Nam & Park, “Comparison of body shape between USA and Korean women,” International Journal of Clothing Science and Technology, 19(5), 2007. The round/apple reading and the separate five-shape men's model (trapezoid, rectangle, oval, triangle, inverted triangle) are Duga additions for cases the original seven don't cover.

Beyond shape

Waist-to-hip ratio

Your result also shows your waist-to-hip ratio (WHR) — waist divided by hips. Unlike body shape, which is about styling, WHR is a number health researchers actually use. Here's the plain version, with the reference bands and an honest note on what they do and don't mean.

WHR is a rough, population-level indicator of where weight tends to sit, not a verdict on any individual. Health bodies including the WHO and NIDDK use higher WHR — more weight around the middle — as one signal among many that can correlate with cardiovascular and metabolic risk.

It says nothing about your fitness, and it can't diagnose anything on its own. A single measurement, taken at home, is a starting point for a conversation with a clinician — never a substitute for one.

Reference bands per WHO and the US National Institute of Diabetes and Digestive and Kidney Diseases. Thresholds differ by source and population; treat them as approximate.

Before you enter numbers

How to measure well

A silhouette is only as honest as the tape. Stand straight with arms at your sides, keep the tape snug but not compressing, and hold it parallel to the floor. Measure over close-fitting clothing.

Bust or shoulders

Women: the circumference around the fullest part of the bust, over a properly fitted bra. Men: the broadest line across the shoulders or chest — whichever you can repeat consistently.

Waist

The smallest circumference around the natural waist, just above the belly button. If it's hard to find, bend gently to one side — the crease marks it.

High hip

The upper swell of the hip over the pelvic region, roughly 7 in / 18 cm below the natural waist. This is what separates the close pear-family shapes.

Hips

The largest circumference around the fullest part of the buttocks, heels together so the tape stays level front to back.
