How to find your body shape: a body shape calculator that actually works

Body shape calculator: three measurements, simple ratio rules, find your shape. Hourglass, rectangle, triangle, inverted triangle, or oval. 10 minutes.

If you've ever typed "what body shape am I" into a search bar at 10pm, frustrated with a wardrobe full of clothes that don't quite work, I want you to know something first. You're not the problem. The clothes are.

Knowing how to find your body shape isn't about labelling yourself or squeezing into a category. It's a styling tool, nothing more. The moment you understand the natural proportions between your shoulders, your waist and your hips, shopping gets dramatically easier. You stop buying trousers that fight your frame. You stop wondering why a dress that looked stunning on a friend looks lost on you. You start choosing pieces that actually work with your body.

How do you find your body shape?

You find your body shape by taking three measurements (your shoulders or bust, whichever is wider, your natural waist, and your hips at their widest point) then comparing them against simple ratio rules. The result is one of five canonical shapes: hourglass, rectangle, triangle (pear), inverted triangle, or oval (apple). It takes about ten minutes and you don't need a calculator app, just a tape measure, a mirror, and the ratio rules below.

If measuring isn't appealing, and many women don't fancy the tape, the body shape quiz does the same thing visually in about four minutes. Pick six silhouettes that match what you see in the mirror, and I work out your shape from there. Same five outcomes, no measurements. Either route gets you to the right shape-specific capsule wardrobe, which is what actually matters.

This guide walks you through the measurement route properly. Three measurements, a clear set of ratio rules, and a direct route to the shape-specific capsule wardrobe that fits you. Ten minutes. That's all this takes.

What you'll need

Before we start, gather these. It genuinely makes a difference to how accurate your result will be.

  • A flexible tape measure (the soft fabric kind, not a DIY metal one)
  • A full-length mirror
  • Underwear or close-fitting clothes: baggy jumpers and jeans will give you numbers that don't reflect your actual frame
  • Ten quiet minutes without being interrupted
  • A piece of paper or a notes app to write your numbers down

A small tip: measure in front of the mirror rather than looking down at the tape. Looking down distorts the position of the tape on your body, especially at the waist. Stand tall, relax your shoulders, and keep the tape parallel to the floor all the way around.

The three measurements you need

You only need three numbers to find your shape. Shoulders or bust, waist, and hips. I'll walk you through each one in turn.

Shoulders and bust: finding your "upper" number

You need one measurement for your upper half. For most women that's the bust. For some women with broader shoulders relative to the chest, it's the shoulders. Take both and use the larger of the two. That's the number we'll call your "upper" measurement.

For your bust: Wrap the tape measure around the fullest part of your bust, keeping it parallel to the floor. Wear a normal, supportive bra, not a push-up and not a sports bra. Breathe normally. Don't pull the tape tight; it should sit flat against you without digging in.

For your shoulders: This one's trickier solo. Stand with your back to the mirror and ask someone to measure across the widest point of your shoulders, from the outside of one shoulder bone to the outside of the other, around your back. If you're on your own, stand with your back flat against a wall and use the tape to mark the widest point of your shoulder line, then measure that span.

Write both numbers down. The bigger of the two is your upper number.

Waist: find your natural waist, not your jean line

This is the measurement women get wrong most often, and it matters hugely. Your natural waist is the smallest point of your torso, which usually sits around an inch above your belly button. It is absolutely not where your low-rise jeans sit.

To find it, put your hands on your sides and bend gently sideways. The crease that forms is roughly your natural waist. Stand up straight again, wrap the tape around that point, and keep it parallel to the floor. Breathe out normally. Don't suck in, don't puff out, just stand as you naturally do.

If you're unsure, try this: tie a piece of string loosely around your middle and move around for a minute. It will naturally settle at your narrowest point. Measure there.

Hips: the widest point around your seat

For your hip measurement, you want the widest point around your hips and bottom, not the bony part at the top of your pelvis. For most women that's about 20cm (8 inches) below the natural waist, but bodies vary, so eyeball the widest visual point in the mirror and measure there.

Stand with your feet together. Wrap the tape around the fullest part, keeping it parallel to the floor. Again, don't pull tight. The tape should rest against your skin without compressing it.

Write the number down. You now have your three measurements: upper, waist, hips.

The ratio rules: which shape are you?

Here's where the three numbers turn into an answer. Read through the rules below in order and stop at the first one that describes you. I've given the thresholds in both centimetres and inches so you can use whichever you measured in. And if you'd rather I did the arithmetic, pop your three numbers into the calculator below, which applies exactly the same rules.

You're an hourglass if…

Your upper number and your hip number are roughly the same (within about 5cm / 2 inches of each other), and your waist is at least 22cm (around 9 inches) smaller than both.

In plain English: your shoulders and hips are balanced, and your waist is clearly, visibly narrower. You have defined curves top and bottom with a strong nip in at the middle.

If that's you, your shape-specific guide is here: Hourglass capsule wardrobe.

You're a rectangle if…

Your upper number, waist and hips are all within about 5cm (2 inches) of each other. There's no pronounced waist definition, so the line from your shoulders to your hips is fairly straight, without a deep curve at the middle.

Rectangle shapes often have long, lean proportions, though this shape appears at every size. The defining feature isn't your size; it's the straightness of the line.

Your shape-specific guide is here: Rectangle capsule wardrobe.

You're a triangle (also called pear) if…

Your hips are more than about 5cm (2 inches) wider than your upper number. Your lower half is visibly fuller than your upper half, so you might carry fullness through the hips, seat and thighs, while your shoulders, bust and waist read as narrower.

"Pear" is the old informal name you'll see around the internet. On Capsule Chic Hub we call this shape triangle, because it more accurately describes what's going on visually.

Your shape-specific guide is here: Triangle capsule wardrobe.

You're an inverted triangle if…

Your upper number is more than about 5cm (2 inches) wider than your hips. Your shoulders or bust read as the widest part of your frame, and your hips are narrower by comparison. Many athletic builds, broad-shouldered frames and fuller-chested women fall here.

Your shape-specific guide is here: Inverted triangle capsule wardrobe.

You're an oval (also called apple) if…

Your waist measurement is equal to or larger than your upper number, and fullness is carried through the midsection rather than at the hips or bust. The waist isn't the narrowest part of your frame, so your shape reads softer and rounder through the middle, often with slimmer legs.

"Apple" is the informal name. We use oval because it's a kinder and more accurate description of a shape that's defined by a fuller midline rather than anything negative.

Not sure? That's completely normal

If your numbers don't fall cleanly into one category, please don't worry. Most women are a blend. You might be an hourglass with a touch of triangle, or a rectangle edging toward oval. That's not a failure of the system; it's just real human bodies, which refuse to be neatly boxed.

Here's what I tell my clients when they're stuck between two shapes.

Go with the dominant line. Look in the mirror in fitted clothing and ask yourself: what do I see first? If the answer is "my hips", you're leaning triangle. If it's "my waist cinching in", you're leaning hourglass. Your eyes will often tell you what the numbers nearly did.

Try both sets of advice. Read both shape-specific capsule guides. Whichever one has you nodding along more ("yes, wrap dresses always work on me" or "no, tops with volume on top actually swamp me") is your shape. Your wardrobe history is honest data.

Lean into the visual proportion. Body shape is about how you read in clothes, not just a spreadsheet. If your measurements say rectangle but you look curvier in fitted dresses than you think you should, trust what you see. Flattering clothes are the goal, not a perfect mathematical result.

And if you're still genuinely unsure, two options. Either take the body shape quiz, which is six visual silhouettes and four minutes, where I work it out from how you answer rather than from numbers. Or read the complete body shapes guide, which walks through all five shapes in more depth with visual cues for each.

Where to go next

Now you know your shape, here's exactly where to go for the styling advice made for you.

Once you've worked through your shape's capsule, the next step is colour. My complete colour palette guide walks you through finding the shades that genuinely suit your skin, hair and eyes. Shape plus colour is where getting dressed stops being a daily battle. And if you want to zoom out, my five-step capsule wardrobe guide ties everything together into a real plan.

A note on changing bodies

One last thing, because I think it matters.

Bodies change. Pregnancy, menopause, weight shifts, simply the passing of years: your shape today is not fixed forever, and nor should it be. I've had clients re-measure themselves every couple of years and find they've drifted from a rectangle to an hourglass, or from a triangle to an oval. That's not a problem. That's just life in a real body.

Re-measuring is kind, not vain. The clothes that worked five years ago may not be the clothes that flatter you now, and that's okay. Your wardrobe deserves to reflect the body you're actually in, not the body you used to have, or the body you're waiting to have. Measure when things feel off. Adjust gently. Keep going.

You don't need to earn the right to dress well. You already have it. The point of this guide is to hand you the tools to do it with less guesswork and more confidence, whatever shape you're in today.

Frequently Asked Questions

How do I know if I'm measuring in the right place?

The most common mistakes are measuring the waist too low (at the jean line rather than the natural waist) and pulling the tape too tight. Your natural waist is the smallest point of your torso, usually about an inch above the belly button. Bend sideways and the crease that forms is roughly where to measure. Keep the tape parallel to the floor and snug but not compressing your skin. If in doubt, measure each area three times and take the average.

What if my measurements don't fit any category?

Most women are a blend of two shapes, and the ratio rules above are guidelines rather than rigid boxes. If you're between categories, look in the mirror in fitted clothing and identify the most dominant visual line. Is it your waist cinching in, your hips widening out, or your shoulders leading the frame? Go with the shape that matches what you see first, and read both nearby shape guides to see which styling advice resonates more.

Do body shapes really change over time?

Yes, they absolutely can. Pregnancy, menopause, weight changes, muscle development and simply the passage of years can all shift the ratio between shoulders, waist and hips. It's completely normal to find you're a different shape in your forties than you were in your twenties, or after having children. Re-measure whenever your clothes start feeling "off", because it's the quickest way to understand why and adjust.

Is body shape the same as body type?

In everyday language the two terms are often used interchangeably, and that's what we do on Capsule Chic Hub. "Body type" and "body shape" both mean the same thing: the ratio between your shoulders, waist and hips (hourglass, rectangle, oval, inverted triangle, triangle). Strictly speaking, "body type" sometimes also refers to somatotypes (ectomorph, mesomorph, endomorph), which relate to build and metabolism. For styling purposes, though, shape is what matters.

Can I be more than one body shape?

You can be a blend, and most women are. You might be primarily hourglass with a slight triangle lean, or a rectangle edging toward oval. When you're a blend, pick the shape that describes your strongest visual line and follow that advice as a baseline, then borrow tips from the secondary shape where they apply. The goal is flattering, not a perfect label.

Do I need to lose weight before figuring out my shape?

Absolutely not, and please don't wait. Body shape is about proportion, not size, and women of every size fall into every shape category. An hourglass at a size 8 has the same shape ratios as an hourglass at a size 22. Dressing for your shape now is one of the kindest things you can do for yourself, and it works at any size. Waiting is just lost time in clothes that don't flatter you.

What's the difference between a triangle (pear) and an oval (apple) shape?

A triangle shape carries fullness in the hips, seat and thighs, with a narrower upper half and a relatively defined waist, so the widest point sits at the hips. An oval shape carries fullness through the midsection, so the waist is equal to or larger than the bust, and the hips are often narrower than the middle. The easy shorthand: triangle fullness sits below the waist, oval fullness sits around the waist.
