Body Visualizer 3D is a free set of tools for seeing a body by its numbers and for learning what is inside one. It opened in November 2026.
What you can do here
The 3D body visualizer draws a figure from a height, a weight and any tape measurements you know, in centimeters and kilograms, feet and pounds, or stone. You can compare two bodies or a row of weights at one height.
Around it sit smaller tools that answer one question each: the BMI visualizer, the body shape calculator, the body fat calculator, the waist to hip ratio calculator, the waist to height ratio calculator and the height comparison.
The 3D anatomy tools let you turn a body around, switch systems on and off, pick out a single bone, muscle or organ and read what it is.
The guides explain the ideas behind the numbers, each with its sources listed.
How the figure is made
The body figure is a 3D model, not a photo and not a scan. Its mesh and shape controls come from the MakeHuman project, which released them into the public domain under the CC0 dedication. The code that measures the model like a tape, fits it to your numbers and draws it was written for this site.
A figure built from a few numbers is an estimate. Two people with the same height, weight and waist can carry their weight differently, so the figure shows a likely body, never yours exactly.
Where the anatomy comes from
The anatomy models are from BodyParts3D, a model of one adult male body made by the Database Center for Life Science in Japan. The credit its license asks for is: BodyParts3D, © The Database Center for Life Science licensed under CC Attribution 4.0 International. The models were reduced in detail so they run on a phone.
What stays on your device
The tools run in your browser. The numbers you type are not sent to a server. The privacy policy has the details.
Who runs it
Body Visualizer 3D is an independent website run by a small team. It is not a clinic, a laboratory or a medical publisher, and what it publishes is not medical advice. The editorial policy says how pages are prepared and corrected.
