Body Visualizer: See Your Body in 3D
Enter your height and weight, and your waist, hips and bust or chest if you know them, then turn the 3D figure built from your numbers. It is an illustration, not a judgement.

How we got it
The figure is an open-source MakeHuman body with built-in shapes for weight, muscle and the circumference of waist, hips and bust. We scale it to your height, choose the weight shape so its volume matches your weight (about 1 kg per litre), then adjust the waist, hip and bust shapes until the tape measures taken on the figure itself match yours, within about 3 cm. It shows shape only: two people with the same numbers can look different, and the figure stops at its heaviest shape, around a BMI of 35.

The evidence
Every recommendation on this page links here. The badge shows what kind of source it is, so you can judge how strong it is.
- Model
The figure is a MakeHuman body: an open, CC0-licensed human model with built-in shapes for weight, muscle and the circumference of waist, hips and bust. We fit those shapes to your numbers; it is an illustration, not a measurement of your body.

- Guideline
For adults with a BMI under 35: 0.4 to 0.49 is healthy, 0.5 to 0.59 increased risk, 0.6 or more high risk; keep your waist to less than half your height. Measure midway between the bottom of the ribs and the top of the hips (just above the belly button), after breathing out, and use it alongside BMI.

Our own rules of thumb
These are our choices, not findings from a study. We list them so you know which parts are judgement calls.
- The figure's volume is matched to your weight at about 1 kg per litre, our approximation of body density.
- The figure stops at its heaviest shape, around a BMI of 35; above that it cannot show a body honestly.
- Tape measures are matched to within about 3 cm, or we say which one the figure could not reach.
- Soft, average and muscular builds are our own settings of the model's muscle shape.
Questions
How accurate is the body visualizer?
It matches your height and weight, and your waist, hips and bust within about 3 cm when you add them. Where fat and muscle sit differs from person to person, so it shows a likely shape for your numbers, not your exact body.
Why does the figure stop getting bigger?
The model's heaviest shape is around a BMI of 35. Pushing it further made the body look unnatural, so we stop there and say so rather than show something misleading.
Are my numbers saved or sent anywhere?
No. The figure is built in your browser; your numbers stay on your device.
Can I see what I would look like after losing weight?
Yes: enter your goal weight, and a smaller waist if you expect one, and compare the two figures. Real change also depends on where you lose first, which differs between people.
Is there a female body visualizer?
Yes. Pick the female figure for a body with hips and bust, or the male figure for chest and waist.
