What Is a Body Shape Calculator?
A body shape calculator identifies your body type from the proportional relationship between your bust, waist, and hip measurements. Enter your three measurements and it classifies your figure instantly, then offers style tips that suit your natural proportions.
It is built for anyone choosing clothes that flatter their figure — from picking the right dress cut or neckline to building a wardrobe you feel confident in. The result is not about fitting a category; it is about understanding your own proportions. The tool recognizes seven shapes, including the Top Hourglass and Bottom Hourglass variations for when your measurements lean slightly toward your bust or hips.
The Body Shapes Explained
Most figures fall into one of five main categories, with the hourglass splitting into balanced and slightly top- or bottom-weighted variations:
Hourglass
Bust and hips are balanced around a clearly defined, narrower waist — the classic proportional shape.
Pear (Triangle)
Hips are noticeably wider than the bust, usually with a defined waist and a slimmer upper body.
Inverted Triangle
Bust and shoulders are broader than the hips, giving an athletic upper body.
Rectangle
Bust, waist, and hips are similar in width, for a straight, streamlined silhouette.
Apple (Round)
The midsection is the widest area, often with slimmer hips and legs.
Hourglass Variations
Top and Bottom Hourglass keep the defined waist but lean slightly toward a larger bust or larger hips.
How to Use the Body Shape Calculator
Take your measurements
Use a soft tape and stand straight. Measure your bust at the fullest part of your chest, your waist at the narrowest point of your torso, and your hips at the widest part of your hips and buttocks.
Pick units and enter values
Switch between Metric (centimeters) and Imperial (inches), then type your bust, waist, and hip measurements. Results update instantly as you type.
Add shoulder width (optional)
Open Advanced Measurements and enter your shoulder width for more precise results. This helps the calculator distinguish an Inverted Triangle when your shoulders are broader than your bust.
Read your result
See your body shape with a visual silhouette, your key ratios — Waist-to-Hip, Bust-to-Hip, and Bust-to-Waist difference — and style tips tailored to your shape.

Frequently Asked Questions
How do I calculate my body shape?
Measure your bust, waist, and hips, choose Metric or Imperial, and type the three values in. The calculator compares the ratios between them and shows your shape — along with your key ratios and style tips — the moment all three fields are filled.
What measurements do I need?
You need three: bust, waist, and hips. Measure the bust around the fullest part of your chest, the waist at the narrowest part of your torso, and the hips at the widest part of your hips and buttocks. Shoulder width is optional and only sharpens borderline results.
Where exactly is my natural waist?
Your natural waist is the narrowest part of your torso, usually above the belly button and below the ribcage. Bend to one side — the crease that forms marks your natural waistline.
What are the body shape types?
The five main shapes are Hourglass, Pear (Triangle), Inverted Triangle, Rectangle, and Apple (Round). This calculator also splits the hourglass into Top Hourglass and Bottom Hourglass for figures that lean slightly toward a larger bust or larger hips, for seven shapes in total.
How does the waist-to-hip ratio work?
The Waist-to-Hip Ratio is your waist measurement divided by your hip measurement. A lower number means a more defined waist relative to your hips. The calculator shows it alongside the Bust-to-Hip ratio and the Bust-to-Waist difference to explain how it reached your shape.
Why should I add my shoulder measurement?
Shoulder width can differ from bust measurement, especially for athletic figures. Entering it under Advanced Measurements helps the calculator tell an Inverted Triangle apart from other shapes when broad shoulders are the defining feature.
Can my body shape change over time?
Yes. Body shape can shift with weight changes, exercise habits, aging, and hormonal changes. It is worth re-measuring periodically, especially after a noticeable change in weight or fitness level.
Is one body shape better than another?
No. Every shape is normal, and these categories are simply tools to help with clothing choices and understanding your proportions — not a definition of beauty. For borderline measurements your figure may show traits of more than one shape.
