Use this free Body Shape Calculator to estimate your body shape from bust, waist, high hip, and hip measurements. It also shows your waist-to-hip ratio so you can better understand your overall body proportions.
Enter your measurements below and click the button to calculate your estimated body shape instantly. This tool is best used as a body proportion guide, not a medical diagnosis.
How to Use This Body Shape Calculator
Measure your bust, waist, high hip, and hips with a flexible measuring tape. Select your unit, enter each value, and click the calculate button. The tool compares these measurements to estimate your body shape and also shows your waist-to-hip ratio.
For the most useful result, keep the tape level around your body and do not pull it too tightly. The result works best as a clothing, styling, and proportion guide.
What Is a Body Shape Calculator?
A Body Shape Calculator is a tool that estimates body shape by comparing key body measurements. In most cases, it looks at the relationship between bust, waist, and hip size. Some methods also include high hip measurement to refine the result.
Common body shape categories include hourglass, triangle, spoon, rectangle, and inverted triangle. These labels describe body proportions, not health status, beauty standards, or medical conditions.
Why Use Our Body Shape Calculator?
This calculator gives you a quick estimate of your natural body proportion pattern. It can help with clothing choices, size comparisons, personal styling, and general body measurement awareness.
The tool also shows waist-to-hip ratio, which can give extra context about how your waist compares to your hip measurement.
Useful Benefits

- Supports cm and inches
- Uses bust, waist, high hip, and hip measurements
- Shows waist-to-hip ratio automatically
- Simple layout for mobile and desktop
Formula and How It Works
This tool does not use one single equation like BMI. Instead, it compares the differences between your bust, waist, high hip, and hip measurements. The result is then matched to a common body shape pattern.
The waist-to-hip ratio is calculated with this formula:
Waist-to-Hip Ratio = Waist ÷ Hip
The body shape result is an estimate based on proportion rules. It is best used for body shape guidance rather than medical interpretation.
Body Shape Categories Explained
| Body Shape | General Meaning |
|---|---|
| Hourglass | Bust and hips are fairly balanced, with a clearly smaller waist. |
| Top Hourglass | The bust is slightly fuller than the hips, with a defined waist. |
| Bottom Hourglass | The hips are slightly fuller than the bust, with a defined waist. |
| Spoon | The hips are noticeably larger than the bust, often with more curve through the lower body. |
| Triangle | The lower body is broader than the upper body, but the waist is less sharply defined than hourglass forms. |
| Inverted Triangle | The upper body or bust is broader than the hips. |
| Rectangle | Bust, waist, and hips are relatively close in proportion, with less waist definition. |
Example Calculation
Suppose your measurements are: bust 94 cm, waist 74 cm, high hip 92 cm, and hips 99 cm.
Waist-to-hip ratio = 74 ÷ 99 = 0.75
Because the hips are a little larger than the bust and the waist is clearly smaller, the result may fall into a bottom hourglass or spoon style pattern depending on the exact proportion.
Why Body Shape Can Matter
Knowing your body shape can be helpful for choosing clothing cuts, comparing size charts, and understanding how garments may fit around the upper body, waist, and hips. It can also help you track body proportion changes over time.
Still, body shape should never be treated as a health diagnosis. Many people have mixed proportions that do not fit perfectly into one category, so the result should be used as a practical estimate.
