Is body shape the same as body size?

No. Body shape compares proportions, while body size describes absolute measurements or clothing size. Two people can have the same shape estimate and very different sizes.

Should I use inches or centimeters?

Either is fine as long as all four measurements use the same unit. The calculator compares ratios and differences, so mixed units will produce a wrong result.

Why does my result differ from a clothing brand's guide?

Brands may use different thresholds, include shoulder width, or design around their own fit models. Use this calculator as a general measurement guide, then check the brand's size chart.

Body Shape Estimation Method

Body shape = compare bust, waist, high hip, and hip proportions

A body shape calculator compares the relative difference between bust and hip measurements, then checks whether the waist is clearly smaller than the bust and hips. The result is a practical clothing-fit category, not a health diagnosis.

Symbol	Variable	Description
Bust	Bust measurement	Measure around the fullest part of the bust while keeping the tape level.
Waist	Waist measurement	Measure around the narrowest comfortable point of the torso.
Hip	Hip measurement	Measure around the fullest part of the hips and seat.

How to Use the Body Shape Calculator

1
Measure with a soft tape
Keep the tape level and snug, but not tight. Use the same unit for every field.
2
Enter bust and waist
Bust and waist measurements help determine whether the torso has strong waist definition.
3
Enter high hip and hip
High hip and hip measurements help separate top-heavy, bottom-heavy, and balanced proportions.
4
Read the estimate
Use the category as a fit guide for clothing cuts, not as a fixed label or health measure.

What Body Shape Categories Mean

Common body shape labels describe measurement proportions. They are most useful for comparing garment cuts, waist placement, and how fitted clothing may sit on the body.

Hourglass estimates usually have similar bust and hip measurements with a smaller waist.
Triangle estimates usually have hips noticeably larger than bust.
Inverted triangle estimates usually have bust or shoulders visually larger than hips.
Rectangle estimates usually have bust, waist, and hip measurements closer together.

Example Measurements

These examples show how different proportions can lead to different estimates.

Bust	Waist	Hip	Likely estimate
38 in	28 in	39 in	Hourglass
34 in	29 in	40 in	Triangle
41 in	32 in	36 in	Inverted triangle
36 in	33 in	37 in	Rectangle

Measurement Limits

No body shape calculator can account for posture, shoulders, muscle distribution, fabric stretch, brand sizing, or personal fit preference. Treat the result as a starting point for choosing clothing silhouettes.
