This body shape calculator tells you which of the five common body types you fall into — hourglass, pear, inverted triangle, rectangle, or apple — using three simple measurements: your shoulders or bust, your waist, and your hips. No visual guessing or comparing yourself to photos online. Just enter your numbers and get a clear answer, plus a quick styling tip for your shape.
What this result tells you:
Your body shape is about proportion, not size — a petite hourglass and a plus-size hourglass share the same underlying ratio between shoulders, waist, and hips. It’s a useful reference for styling decisions, and, as it turns out, it also lines up with some genuinely interesting health research around where the body tends to store fat. If you want to look at that side of things more closely, our Waist to Hip Ratio Calculator is the more clinical version of a very similar measurement.
What is a body shape calculator, and how does it decide your shape?
A body shape calculator compares three measurements — your shoulders or bust, your waist, and your hips — and looks at the ratios between them rather than any single number on its own. It’s not about how big or small you are; two people with very different measurements can land in the exact same shape category if their proportions match. What actually separates one shape from another is how much your waist narrows compared to your shoulders and hips, and whether your upper body or lower body carries more visual width.
This calculator sorts everyone into one of five categories that come up across most style guides and body-shape tools: hourglass, pear (also called triangle), inverted triangle, rectangle, and apple (also called round). None of them is “better” than another — they’re just different starting points for figuring out what fits.
How this calculator works
The math behind it comes down to two questions, checked in order:
- How much smaller is your waist than your shoulders and hips? A waist that’s 25% or more narrower than both points toward an hourglass shape. A waist within about 5% of your shoulders or hips signals very little natural waist definition, which points toward an apple shape instead. Anything in between reads as a straighter, less dramatically curved silhouette.
- Which is wider — your shoulders or your hips? If your hips run more than about 5% wider than your shoulders, the lower body carries more visual weight, which is the defining trait of a pear shape. If it’s the reverse — shoulders clearly wider than hips — that’s an inverted triangle. If shoulders and hips are close to even, the shape comes down entirely to how defined your waist is.
Put together, those two checks are what separate a rectangle (fairly even all the way down, without a sharply defined waist) from an hourglass (also fairly even shoulder-to-hip, but with a much more defined waist), and what separates a pear from an inverted triangle (same waist definition, opposite direction of imbalance). Like any measurement-based method, results near a threshold can read as borderline between two shapes — that’s normal, and worth knowing rather than something to worry about.
How to use this body shape calculator
Measure your shoulders or bust
Wrap the tape around the fullest part of your chest, under your arms, keeping it level and not pulled tight. If you’d rather measure your shoulders directly, measure straight across from the edge of one shoulder to the other and use that number instead — either works with this calculator.
Measure your waist
Find the narrowest point of your torso, usually just above your belly button, and wrap the tape around without sucking in or holding your breath. A relaxed, natural measurement gives a far more useful result than a tightened-up one.
Measure your hips
Stand with your feet together and measure around the widest part of your hips and buttocks, keeping the tape level all the way around.
Get your result
Enter all three numbers in centimeters and tap calculate. You’ll get your shape, a short explanation of what defines it, and a quick styling note to work with rather than against your proportions.
What to do with your body shape result
Use it to shop with more confidence
Knowing your shape narrows down what to actually try on, instead of guessing your way through a rack of clothes. A wrap dress that looks incredible on an hourglass frame can read completely differently on a rectangle frame, and neither is a flaw in the dress or the body — it’s just proportion. The styling tip in your result is a starting point, not a rulebook; the goal is fewer disappointing fitting-room moments, not a strict set of rules to follow.
Use it alongside your other body measurements
Body shape is about proportion, and it pairs naturally with other measurements that look at your body from a different angle. Your Waist to Hip Ratio Calculator result and your BMI Calculator Philippines result both use some of the same numbers you just entered here, so it’s worth checking both while you have your measurements handy.
Understand what your shape can (and can’t) tell you about health
Where your body tends to store fat isn’t purely cosmetic. A large review of 72 studies found that people who carry more weight around the midsection — the apple pattern — had a meaningfully higher risk of death from any cause compared to people who carry weight in the hips and thighs, the pear pattern, according to a Healthline review of the research. That said, body shape alone isn’t a diagnosis, and it isn’t the full picture — genetics, overall body fat percentage, and standard measures like blood pressure and cholesterol all matter more than shape by itself. If you carry more weight around your midsection, that’s useful context for a conversation with a doctor, not a verdict on its own.
The five body shapes, explained
- Hourglass: Shoulders/bust and hips are close in size, with a waist that’s clearly narrower than both — roughly a quarter smaller or more.
- Pear (Triangle): Hips are noticeably wider than shoulders or bust, with a defined waist in between. The lower body carries more visual width.
- Inverted Triangle: Shoulders or bust are noticeably broader than hips, with some waist definition still present. The upper body carries more visual width.
- Rectangle: Shoulders, waist, and hips are all fairly close, without a sharply defined waist. Reads as fairly straight up and down.
- Apple (Round): Waist is close to or larger than shoulder/bust and hip measurements, so the midsection carries more visual width than a defined waistline would.
Frequently asked questions
What body shape am I based on my measurements?
Take your shoulder or bust, waist, and hip measurements in centimeters and enter them above. The calculator compares how much smaller your waist is than your shoulders and hips, and which of the two is wider, to sort you into hourglass, pear, inverted triangle, rectangle, or apple. There’s no visual guessing involved — it’s the same three numbers every time.
Do I need to include my shoulders, or is bust measurement enough?
Either works. Shoulder width and bust measurement tend to move together for most people, which is why calculators (and this one) accept either. If your shoulder width and bust size are noticeably different from each other — broader shoulders with a smaller bust, for example — go with whichever feels like the true widest point of your upper body.
My result feels borderline between two shapes. Is that normal?
Yes, and it’s actually common. Body shape categories are built around thresholds, not hard lines, so measurements close to a cutoff can genuinely sit between two shapes. If you’re right on the edge between rectangle and hourglass, for instance, you likely have a body that reads as a bit of both depending on what you’re wearing — that’s useful information in itself, not an error.
Does my body shape change if I lose or gain weight?
The underlying proportions usually stay fairly consistent, since where you naturally carry weight is largely genetic. That said, significant weight changes can shift your numbers enough to move you across a threshold — someone close to the apple/rectangle border, for example, might land differently after a meaningful change in midsection measurement. It’s worth recalculating periodically rather than assuming your shape is fixed forever.
Is one body shape healthier than another?
Not on its own. Research does show that carrying more weight around the midsection (the apple pattern) is associated with higher cardiovascular risk than carrying weight in the hips and thighs (the pear pattern), but body shape is only one data point. Overall body fat percentage, activity level, diet, and standard medical measures like blood pressure and cholesterol tell a much fuller story than shape alone. Treat this as useful context, not a health verdict.
What’s the difference between this and the Waist to Hip Ratio Calculator?
Your Waist to Hip Ratio Calculator focuses specifically on the relationship between two measurements — waist and hip — mainly as a health-risk indicator. This Body Shape Calculator adds a third measurement (shoulders/bust) and is built around style and proportion rather than health risk specifically, sorting you into one of five recognizable shape categories. They use overlapping numbers but answer different questions.
Can men use this calculator too?
Yes. The underlying proportions — how your waist compares to your shoulders and hips — apply regardless of gender, even though some style guides use different names for men’s shapes (trapezoid, oval, triangle). The shoulder/bust field works the same way for a male chest or shoulder measurement.
