Body Shape Calculator – Find Your Body Type by Measurements
Body Shape Calculator
Find your body-shape proportion category — hourglass, pear, inverted triangle, rectangle, or apple — from your bust/chest, waist, and hip measurements. This is a descriptive proportion classification, not a health, fitness, or attractiveness score.

Shoulders and high hip are shown as extra reference ratios below your result. They do not change the calculated category in this calculator's current methodology.
This calculator uses one specific, documented set of proportion rules (see Methodology below). No body-shape classification system is universally standardized, and no category is better, healthier, or more attractive than another.
What is my body shape?
Your body shape is determined by the relative proportions of your bust or chest, waist, and hips. This calculator compares those three measurements using a documented set of rules and assigns the closest proportional category — hourglass, pear, inverted triangle, rectangle, or apple.
Is body shape scientific?
There's no single universally accepted body-shape classification system. Different systems use different measurements, thresholds, and category names. This page discloses exactly which rules this calculator uses, so you know what the result is — and isn't — based on.
Is body shape the same as BMI or body fat?
No. BMI uses height and weight; body fat percentage estimates fat mass. Body shape compares the proportions between bust, waist, and hip measurements — it's a different concept from both.
Key Facts
Body shape describes proportions, not size, weight, or health.
There is no single universal body-shape classification system.
This calculator uses one documented, transparent rule set.
Classification is based on bust/chest, waist, and hip measurements.
No body shape is better, healthier, or more attractive than another.
Body shape can change with age, weight, training, and other factors.
Body shape does not determine clothing size.
Measurements near a category threshold can be borderline.
What Is Body Shape?
Body shape, as used on this page, is a descriptive classification of how your bust/chest, waist, and hip measurements relate to each other — not a measurement of health, fitness, attractiveness, or worth. Two people can be the same height and weight and have completely different body shapes, because shape describes proportion, not size.
This is a body-proportion and styling reference, not a medical, diagnostic, or clinical assessment.
How This Calculator Works
This calculator uses one specific, fully documented methodology rather than blending rules from different sources. It classifies proportions using percentage differences between your bust/chest (B), waist (W), and hip (H) measurements, which makes the result unit-invariant — the same in centimeters or inches, as long as you're consistent within one calculation.
The rules, in order
Apple (torso-dominant): if waist is at least 90% of the larger of bust/chest and hips (W ≥ 0.90 × max(B,H)) → Apple.
Hourglass: otherwise, if bust and hips are within 5% of each other, and the waist is on average at least 25% smaller than both → Hourglass.
Pear/Triangle: otherwise, if hips are at least 5% larger than bust/chest → Pear/Triangle.
Inverted Triangle: otherwise, if bust/chest is at least 5% larger than hips → Inverted Triangle.
Rectangle: otherwise (bust and hips within 5% of each other, but the waist isn't substantially smaller) → Rectangle/Straight.
Results within about 2 percentage points of a rule's threshold are flagged as borderline, and the closest competing category is named.
Bust-to-hip difference = (Bust − Hips) / Hips
Waist drop = average of [(Bust − Waist)/Bust] and [(Hips − Waist)/Hips]
Provenance and honesty note: these thresholds are this calculator's own documented convention, informed by the kind of bust/waist/hip comparisons commonly used across apparel and styling contexts — they are not presented as a peer-reviewed medical standard or as "the" universally correct body-shape algorithm. Published apparel and anthropometric research (for example, systems that classify body shape from body scan data for clothing-fit purposes) uses various numbers of measurements and different thresholds; no single one of those systems is treated here as more "correct" than another. This calculator's specific rule set is disclosed above so you can judge the result on its own terms.
How to Measure Your Body
Stand naturally, without straining your posture.
Use a soft, flexible tape measure and keep it level all the way around.
Don't pull the tape excessively tight — snug is enough.
Measure over light clothing or directly against skin, consistently.
Bust/chest: around the fullest part of the chest/bust.
Waist: around the narrowest point of your torso, usually just above the belly button.
Hips: around the fullest, widest part of your hips and buttocks.
Optional — shoulders: shoulder circumference around the widest point (not shoulder-to-shoulder breadth); high hip: the upper hip area a few inches below the natural waist.
Don't hold your breath or deliberately change your posture while measuring.
Repeat any measurement that seems inconsistent — consistency matters more than pretending the number is exact to the millimeter.
Body Shape Categories
The five categories below are the only ones this calculator's methodology assigns. No category is described as better, healthier, or more attractive than another — these are descriptive labels, not a ranking.
Hourglass
Typical pattern: bust and hips relatively balanced, with a noticeably narrower waist.
Illustrative proportion pattern — not a photograph or medical assessment.
What distinguishes it: the near-equal bust/hip measurement combined with a substantial waist reduction from both. Limitation: requires both the balance and the waist criteria — close on one but not the other typically lands in Rectangle instead.
Pear / Triangle
Typical pattern: hips measurably larger than bust/chest, giving a lower-body-dominant proportion.
Illustrative proportion pattern — not a photograph or medical assessment.
What distinguishes it: hip measurement at least 5% above bust/chest. This pattern is not equated with a particular weight, fitness level, or fat-distribution health category.
Inverted Triangle
Typical pattern: bust/chest measurably larger than hips, giving an upper-body-dominant proportion.
Illustrative proportion pattern — not a photograph or medical assessment.
What distinguishes it: bust/chest measurement at least 5% above hips. This pattern is not equated with athleticism, masculinity, or health status.
Rectangle / Straight
Typical pattern: bust, waist, and hips relatively similar, without a pronounced waist indentation under this methodology.
Illustrative proportion pattern — not a photograph or medical assessment.
What distinguishes it: bust and hips within 5% of each other, but the waist isn't reduced enough to qualify as Hourglass. Not equated with a lack of femininity, attractiveness, or fitness.
Apple
Typical pattern: waist measurement close to or larger than both bust/chest and hips — a torso-dominant proportion with less waist definition.
Illustrative proportion pattern — not a photograph or medical assessment.
What distinguishes it: waist at or above 90% of the larger of bust/chest and hips. This is a proportion label only — it is not a medical diagnosis and does not indicate visceral fat, disease risk, or metabolic health by itself.
Additional shapes (not implemented here)
Some body-shape systems include further categories such as Spoon (hips larger than bust with a defined waist and extra upper-hip fullness) or Diamond. This calculator's current methodology does not implement these as separate categories — measurements matching that general pattern are classified as Pear/Triangle here. A category is not added to this page simply because it's searched for elsewhere; it's only added when the underlying rule is actually implemented.

Worked Examples
Example 1 — Hourglass
Bust 91 cm, Waist 66 cm, Hips 94 cm Bust-hip difference: (91−94)/94 = −3.2% (within 5% → balanced) Waist drop: avg[(91−66)/91, (94−66)/94] = avg[27.5%, 29.8%] = 28.6% (≥25%) → Hourglass
Example 2 — Pear / Triangle
Bust 91 cm, Waist 71 cm, Hips 107 cm Bust-hip difference: (91−107)/107 = −15.0% (hips ≥5% larger) → Pear / Triangle
Example 3 — Inverted Triangle
Bust 107 cm, Waist 81 cm, Hips 94 cm Bust-hip difference: (107−94)/94 = +13.8% (bust ≥5% larger) → Inverted Triangle
Example 4 — Rectangle / Straight
Bust 91 cm, Waist 81 cm, Hips 94 cm Bust-hip difference: −3.2% (within 5% → balanced) Waist drop: avg[(91−81)/91, (94−81)/94] = avg[11.0%, 13.8%] = 12.4% (<25%) → Rectangle / Straight
Example 5 — Apple
Bust 97 cm, Waist 91 cm, Hips 102 cm Waist vs 90% of larger (max 97,102=102): 90%×102 = 91.8 cm; waist 91 cm is just under → not quite Apple by this measure, illustrating a near-boundary case Adjusting to Waist 92 cm: 92 ≥ 91.8 → Apple
This example also shows how a 1 cm waist difference can shift a borderline result — see Borderline Cases below.
These are hypothetical examples for illustrating the rules, not population data or medical reference values.
Borderline Cases
When a result sits close to a rule's threshold — within about 2 percentage points — this calculator flags it as borderline and names the closest competing category, for example: "Your measurements are close to the boundary between Rectangle and Hourglass." Categories are never assigned randomly; the rule order above is always applied the same way, so the same inputs always produce the same output.
Body Shape vs Other Measures
Body Shape vs Body Size
Two people can share the same body shape while having different heights, weights, clothing sizes, and body compositions. Body shape describes proportion, not size.
BMI uses height and weight; body shape uses proportions between bust, waist, and hip measurements. Two people can share a BMI value but have different body shapes, and two people can share a body shape but have different BMI values. See the BMI Calculator. This page does not use body shape to infer BMI, and doesn't use BMI to infer body shape.
Body Shape vs Waist-to-Hip Ratio
Waist-to-hip ratio (WHR = waist ÷ hip) is a single numerical ratio, while body shape here is a broader classification also involving the bust/chest measurement. Two people can share the same WHR but have different bust/shoulder proportions and therefore different body shapes. This page does not interpret WHR as a medical risk score — that kind of interpretation, where used, should come from authoritative health guidance separate from a styling/proportion classification.
Body Shape vs Waist-to-Height Ratio
Waist-to-height ratio (WHtR = waist ÷ height) is a different metric entirely, sometimes discussed in cardiometabolic health contexts. This calculator does not use body-shape results to infer that kind of health risk — the two concepts are kept separate.
Can Body Shape Change?
Yes. Proportions can shift with age, puberty, pregnancy, weight change, muscle development, hormonal changes, and simply how consistently you measure. Strength training in particular can change shoulder, chest, waist, and hip/thigh measurements over time — but this calculator doesn't infer your exact muscle mass or body-fat change from a shape result; for that, see the Lean Body Mass Calculator and Body Fat Calculator. Weight change can alter your category, but which way it shifts depends on how different regions of your body change relative to each other — this page does not promise that losing or gaining a specific amount of weight will move you from one category to another. Body proportions can also temporarily change during pregnancy; this calculator does not use body-shape classification as a pregnancy-health measure.
How Body Shape Can Help With Clothing Fit
Some people find body-shape categories useful as an optional styling vocabulary — a starting point for thinking about fit and proportion, not a rule to follow. None of the ideas below are prescriptive, and body shape does not determine clothing size — sizing varies by country, brand, garment, fabric, and cut, so this calculator is never a substitute for an actual size chart.
Hourglass: garments that acknowledge waist definition may work well, along with balanced top/bottom proportions — entirely a matter of personal preference.
Pear/Triangle: some people enjoy balancing visual volume between the upper and lower body, though there's no requirement to do so.
Inverted Triangle: balancing upper-body proportions is one optional idea some people explore.
Rectangle: creating or emphasizing waist definition is an option if desired — not a necessity.
Apple: considering comfort and proportion around the torso is one starting point, entirely optional.
Body-shape categories are commonly used across fashion, styling, and personal shopping — but definitions vary between systems, and this page doesn't claim the fashion industry universally agrees on one set of five shapes.
How Accurate Is a Body Shape Calculator?
The arithmetic is exact for the rules this calculator implements, but the classification itself depends heavily on measurement technique, exact landmark choice, tape placement, and this methodology's specific thresholds. Calculation precision is not the same thing as an objective biological truth — a slightly different measuring technique, or a different published methodology, could reasonably produce a different category for the same person. This calculator does not claim a numerical accuracy or confidence percentage.
How to Use the Calculator
Choose centimeters or inches.
Measure your bust/chest, waist, and hips as described above.
Optionally switch on advanced mode to add shoulders and high hip for extra reference ratios.
Enter your measurements.
Select Calculate My Body Shape.
Review your body-shape category and the proportion breakdown explaining why.
If flagged, note whether your result is borderline with a neighboring category.
Explore the optional styling information if it's useful to you — or skip it entirely.
A body shape calculator estimates a descriptive proportion category — such as hourglass, pear, rectangle, inverted triangle, or apple — from body measurements like bust/chest, waist, and hips, using a defined set of comparison rules.
How does a body shape calculator work?
It compares your bust/chest, waist, and hip measurements to each other — looking at how close bust and hips are and how much smaller the waist is — and matches the pattern to the closest category under its documented methodology.
What measurements do I need?
This calculator's core classification needs bust/chest, waist, and hip measurements. Shoulders and high hip are optional and shown as extra reference ratios but don't change the category.
How do I measure my bust?
Wrap the tape around the fullest part of your bust/chest, keeping it level and snug but not tight.
How do I measure my waist?
Measure around the narrowest point of your torso, usually just above the belly button, without holding your breath or pulling the tape tight.
How do I measure my hips?
Measure around the fullest, widest part of your hips and buttocks, keeping the tape level all the way around.
Should I measure my shoulders?
It's optional. This calculator shows a shoulder-to-hip ratio for reference if you enter it, but the primary category is determined by bust, waist, and hips alone.
What is an hourglass body shape?
In this calculator's methodology, hourglass describes a pattern where bust and hips are relatively close in measurement and the waist is noticeably smaller than both.
What is a pear body shape?
Pear (or triangle) describes a pattern where hips are noticeably larger than the bust/chest, giving a lower-body-dominant proportion.
What is an inverted triangle body shape?
Inverted triangle describes a pattern where the bust/chest is noticeably larger than the hips, giving an upper-body-dominant proportion.
What is a rectangle body shape?
Rectangle (or straight) describes a pattern where bust, waist, and hips are relatively similar in measurement, without a pronounced waist indentation.
What is an apple body shape?
Apple describes a pattern where the waist measurement is close to or larger than both the bust/chest and hip measurements, giving a torso-dominant proportion with less waist definition.
What is a spoon body shape?
Spoon is an additional category used by some body-shape systems, generally describing hips noticeably larger than the bust with a defined waist and extra fullness at the upper hip. This calculator's current methodology does not implement a separate spoon category.
Can men use a body shape calculator?
Yes. The same bust/chest, waist, and hip comparisons can be applied to any adult. This calculator does not make biological claims tied to sex — it simply compares the measurements you enter.
Can women use a body shape calculator?
Yes, this calculator is designed to be used by anyone entering bust/chest, waist and hip measurements.
Are body shape categories scientifically standardized?
No. There is no single universally accepted body-shape classification system. Different systems use different numbers of measurements, thresholds, and category names, which is why this page documents its own specific methodology.
Can my body shape change?
Yes. Proportions can change with age, puberty, pregnancy, weight change, muscle development, and hormonal changes, as well as simple measurement technique differences.
Does weight change body shape?
It can, but the resulting category depends on how different body regions change relative to each other, not on weight alone — this calculator can't predict how a specific weight change will affect your proportions.
Does body shape determine clothing size?
No. Body shape describes proportions, not size. Clothing size depends on the country, brand, garment, fabric, and cut — this calculator is not a substitute for a specific garment's size chart.
Is body shape related to BMI?
Not directly. BMI uses height and weight; body shape uses proportions between measurements. Two people can share a BMI but have different body shapes, or share a body shape but have different BMI values.
Is body shape the same as body fat percentage?
No. Body shape describes proportional patterns between measurements, not the percentage of your body that is fat. For that, see the Body Fat Calculator.
Is body shape a measure of health?
No. This calculator does not use body shape to diagnose, score, or rank health. It's a descriptive proportion classification, most commonly used for clothing fit and styling context.
What is the difference between body shape and body type?
The terms are often used interchangeably in casual use. On this page, "body shape" refers specifically to the proportion classification from bust/chest, waist, and hip measurements.
Why do different body shape calculators give different answers?
Different calculators use different measurement sets, thresholds, and rule orders. Because there's no single universal system, the same measurements can be classified differently by different tools.
What if my measurements are between two shapes?
This calculator flags results that are close to a category boundary and names the closest competing category, since small measurement differences can shift a borderline result.
Can I use inches instead of centimeters?
Yes. Switch the unit toggle to inches. Because the classification is based on proportions, the result should be the same whether you enter centimeters or the equivalent inches.
How accurate is a body shape calculator?
The arithmetic is exact for the rules used, but classification depends heavily on measurement technique, landmark choice, and the methodology's thresholds. Calculation precision does not mean there's one objectively correct body-shape answer.
Can I determine body shape from height and weight alone?
No. This methodology requires actual circumference measurements — bust/chest, waist, and hips — since body shape describes proportions that height and weight alone don't capture.
Does body shape determine what clothes I should wear?
No, it doesn't determine anything — it can offer optional styling ideas some people find useful, but what you wear is entirely your choice and preference.
Is one body shape better than another?
No. No body shape is inherently better, healthier, or more attractive than another. These are descriptive proportion categories, not a ranking.
Methodology & Sources
This calculator classifies body shape using percentage differences between bust/chest, waist, and hip measurements, applied in a fixed rule order (Apple → Hourglass → Pear/Triangle → Inverted Triangle → Rectangle), as documented in the Methodology section above. Thresholds (5% bust/hip balance, 25% waist drop, 90% waist-to-max ratio for Apple) are this calculator's own transparent convention, informed by common apparel/styling proportion comparisons rather than attributed to one specific peer-reviewed source.
For broader context, published apparel and anthropometric research has explored classifying body shape from body measurements or 3D body-scan data for clothing-fit purposes, using varying numbers of measurements and thresholds — this calculator does not claim to replicate any single one of those systems exactly, and readers seeking the original academic literature on apparel body-shape classification should consult that research directly rather than treat this page as a citation of it.
