Body shape & waist-to-hip

Body Type Calculator: Shape, WHR & Styling

Q: How many body shapes does this calculator use?

Seven labels: Hourglass, Pear, Apple, Rectangle, Inverted Triangle, Spoon, and Diamond. They come from bust, waist, high hip, and hip circumferences compared with fixed inch thresholds (metric entries are converted internally). Shape is about proportions, not clothing size.

Q: What is the difference between high hip and hip?

High hip is around the upper pelvic curve, usually 3–4 inches below the natural waist. Full hip is the widest point at the buttocks, often 7–9 inches below the waist. The gap between them helps separate Pear from Spoon (Spoon needs a noticeable shelf: full hip minus high hip of at least about 1.5 inches in this tool).

Q: Can my body shape change?

Bone structure stays put; fat and muscle shift with weight, training, pregnancy, and menopause. You might go from a stronger waist definition to a straighter midsection, but you rarely jump from, say, Pear to Inverted Triangle without major proportion change.

Q: Is hourglass the ideal shape?

No. It is one of the rarer patterns in population surveys (often cited around 8% of women), which is why media overrepresents it. Rectangle is common (often cited near 46%). Dress for the shape you have; the labels are styling shorthand, not a grade.

Q: What is waist-to-hip ratio (WHR) on this page?

WHR = waist ÷ hip (same units). It describes where you carry circumference, not your fashion shape label. Pick female or male bands in the tool. This is a screening-style number, not a diagnosis.

Q: Can exercise change my shape label?

You cannot spot-reduce fat from one zone. You can build muscle (shoulders, glutes) so proportions look different. The calculator only sees circumferences today, not effort or genetics.

Q: How accurate is an online shape calculator?

It is only as good as the tape measure. Wrong level (belly button vs natural waist) is the usual error. Measure twice, average, and use the same time of day if you are tracking changes.

Q: Why might Pear and Apple talk about health?

Fat stored more around the waist (higher WHR) is associated with higher cardiometabolic risk in population studies than fat carried lower on the hips. That is separate from whether your outfit label is Pear or Rectangle. Ask a clinician about your risk, not this page.

Shape labels are for styling reference; WHR is a separate health-related number.

Measurements

Units

Bust

Around fullest part of chest

Waist

Natural waistline, above belly button

High hip

Upper hip over pelvic region

Hip

Widest part of buttocks

Sex (WHR cutoffs)

Used only for the waist-to-hip risk bands below, not for inferred shape.

Inferred shape

Rectangle / Banana

Bust, waist, and hips are similar in measurement. Athletic, straight silhouette.

Waist-to-hip

0.74

Low health risk

Female bands: low <0.80 · moderate 0.80–0.85 · high >0.85

Symmetry

Bottom heavy

Lower body is proportionally larger

Styling ideas, Rectangle / Banana

, Create curves with peplum tops and ruffled details
, Belts and layering add dimension to your frame
, Try off-shoulder and sweetheart necklines for upper body definition

Public examples (illustrative): Cameron Diaz, Natalie Portman, Kate Middleton

WHR and health

Shape typing is mainly useful for fit and styling. Waist-to-hip ratio (WHR) is sometimes used alongside BMI in cardiovascular risk discussions.

Female (common bands): low < 0.80 · moderate 0.80–0.85 · higher > 0.85. Male: low < 0.90 · moderate 0.90–0.99 · higher ≥ 1.00.

Low risk

Below moderate thresholds for your sex.

Moderate risk

Between low and high cutoffs for your sex.

Higher risk

Above high-risk cutoff for your sex. Discuss with a clinician.

Population shape estimates

Illustrative distribution from some anthropometric summaries (women-focused studies).

Rectangle

46%

Pear

20%

Apple

14%

Hourglass

Inverted Triangle

12%

Individual variation is normal; labels are not judgments.

28″ waist, 38″ hips → WHR about 0.74

Divide waist by hip and you get 0.74 on those numbers (under 0.80 on the female band in this tool). Shape label is a second step: bust and high hip matter too. With a 36″ bust, 28″ waist, 34″ high hip, and 38″ hips, you often land Rectangle because the waist is 8″ under the bust, not the 9″ the hourglass rule wants. Change the four tapes and both WHR and shape can move.

Four things worth knowing

Shape label and WHR are different outputs

The page shows a fashion-style shape from four circumferences and a separate WHR with low / moderate / high bands by sex. You can be Rectangle in the styling label and still have a low WHR, or the reverse. The calculator banner says shape is for styling reference; treat WHR as the health-adjacent number.

Order of rules matters

The tool checks Hourglass first, then Spoon, Pear, Apple, Inverted Triangle, Diamond, and defaults to Rectangle. Spoon needs hips at least 7″ larger than bust plus a hip shelf; Pear needs at least 3.6″ hip-over-bust with a 7″+ waist gap. Small measurement changes can flip the label if you are near a cutoff.

Tape placement beats brand size

Natural waist is the narrowest torso point (often above the navel), not where jeans sit. Bust is fullest chest; hips are widest at the seat. Two people the same weight and height can wear different sizes but share a shape label if ratios match.

Size and shape are independent

A size 4 and a size 14 can both be Pear. Losing weight usually changes size more than it changes which rule set fires. Styling tips in the results panel are the place for outfit ideas; this article does not repeat a full wardrobe guide.

Body type calculator: shape from four measurements and WHR

Bust, waist, high hip, and hip in → one of seven shape labels plus waist-to-hip ratio. Styling hints live in the tool; not medical advice.

What this calculator does

You enter four circumferences and optional sex for WHR bands. It assigns Hourglass, Pear, Apple, Rectangle, Inverted Triangle, Spoon, or Diamond using inch-based ratio rules, computes WHR, and shows brief styling tips in the results panel.

Outputs:

Shape label, WHR value with low/moderate/high band, symmetry note (balanced / top heavy / bottom heavy), and per-shape styling bullets.
Limits:

No body fat, weight, or age. Shape rules are approximations for styling, not clinical phenotyping. WHR is a population screening metric, not a diagnosis. All math runs in the browser.

The math

WHR is simple; shape uses several if/else checks in inch space (metric converted first).

WHR:

$\text{WHR} = \frac{\text{waist}}{\text{hip}}$
Example: 28″ waist ÷ 38″ hips ≈ 0.74.
Hourglass:

|bust − hip| ≤ 1″, hips not much larger than bust, and waist at least 9″ smaller than both bust and hips.
Spoon:

Hips ≥ 7″ larger than bust, waist at least 7″ below hips, and full hip minus high hip ≥ about 1.5″ (shelf).
Pear:

Hips ≥ 3.6″ larger than bust and waist at least 7″ below hips (checked after Spoon).
Apple:

Waist ≥ 90% of hip, or bust notably larger than hips with waist less than 9″ under bust.
Inverted triangle:

Bust more than 3.6″ larger than hips and waist at least 9″ below bust.
Diamond:

Waist larger than 75% of bust and 75% of hip, with bust-waist and hip-waist gaps both under 6″.
Rectangle:

Default when no other rule matches (common on the default 36″ / 28″ / 34″ / 38″ example).

Using the calculator

Use a soft tape, parallel to the floor, without sucking in the waist. Read shape and WHR together; do not treat the shape name as a health grade.

Measurements:

Thin clothing or bare skin. High hip is easy to skip; include it for Spoon vs Pear.
WHR bands:

Toggle female or male to match the cutoffs shown under the result. They differ from some textbook charts that stop male high risk at 0.95; this UI uses ≥ 1.00 for male high.
Styling:

See the bullet list in the results card for your shape. Population percentages in the UI (e.g. ~46% rectangle) are illustrative, not a census of users.
Privacy:

Nothing leaves your browser.
