3D Body Visualizer: Explore Your Body Shape
Adjust your measurements in this 3D Body Visualizer to explore an estimated silhouette. The preview is educational and is not a scan or medical assessment.
These results are estimates for visualization only, not a diagnosis or prediction.

How body visualizers work
A 3D Body Visualizer converts measurements into a simplified 3D silhouette. It scales a base model for height, adjusts width and depth from weight or BMI, then changes proportions from waist, hips, chest or bust, inseam, and shoulders.
BMI and waist ratios are arithmetic outputs. The 3D preview is an estimate because measurements cannot fully describe muscle distribution, posture, bone structure, hydration, genetics, or real tissue distribution.
A 3D Body Visualizer is useful for comparing proportions and scenarios. It is not a clinical composition test, medical scan, or guaranteed prediction of future appearance.
How to use the 3D Body Visualizer
Start with height and weight. The tool creates an initial estimate and updates it as you add detail, giving you a fast visual reference without photos.
Open advanced measurements for waist, hips, chest or bust, inseam, shoulders, or body fat. Use goal comparison for a target scenario, and rotate or zoom the model while adjusting values.

What measurements can you enter?
Height and weight set the preview's overall scale. They create a quick estimate but cannot explain distribution; people with the same BMI can have different proportions.
Waist, hips, chest or bust, inseam, shoulders, and body fat refine the estimate. Separate goal values let you compare today with a possible future scenario.
Height and weight
Basic inputs for the initial estimate.
Chest or bust
Affects upper-body width.
Waist
Strongly affects visible shape differences.
Hips
Affects the lower-body outline.
Inseam
Helps estimate leg-length proportion.
Goal values
Compare current values with a target scenario.
How we calculate your metrics
These metrics explain the preview, not diagnose health. BMI is a broad height-to-weight reference and cannot distinguish muscle, fat, bone, water, or other normal variation.
Waist-to-hip ratio describes proportion and distribution. Estimated body fat uses a common formula based on BMI, an assumed adult age, and selected model type; direct methods may differ.

BMI visualizer
Adds visual context to BMI by showing how height and weight may translate into a rough silhouette.
Waist-to-height ratio
Compares waist circumference with total height and is often discussed around a 0.5 reference point.
Waist-to-hip ratio
Compares waist circumference with hip circumference to describe proportion and distribution.
BMI (Body Mass Index)
BMI = weight (kg) / height (m)^2A broad adult height-to-weight indicator that does not account for muscle mass or fat distribution.

WHtR = waist (cm) / height (cm)A ratio near 0.5 is commonly discussed as a simple adult screening boundary.
Source: Browning, Hsieh, and Ashwell systematic reviewWaist-to-hip ratio
WHR = waist (cm) / hips (cm)Describes proportion; lower values suggest more weight carried at the hips relative to the waist.
Estimated body fat %
BF% = 1.20 x BMI + 0.23 x Age - 10.8 x Sex - 5.4Deurenberg adult prediction formula. The 3D Body Visualizer assumes age 30; sex is 1 for male and 0 for female.

BMI uses weight divided by height squared. It is fast and consistent but cannot show distribution or distinguish muscle, fat, bone, and water.
A 3D Body Visualizer adds waist, hips, chest or bust, inseam, and sometimes shoulders to distinguish people with the same BMI but different proportions.
BMI is a simple screening ratio; a 3D visualizer is a proportion and scenario tool. One summarizes size, while the other shows how measurements may change a silhouette.
| Method | Inputs | Outputs | Best for | Limitation |
|---|---|---|---|---|
| 3D Body Visualizer | Height, weight, and optional measurements | Estimated 3D shape, BMI, body fat estimate, ratios | Visual proportion planning and goal comparison | Estimated silhouette, not a scan or diagnosis |
| BMI calculator | Height and weight | One BMI number | Fast adult height-to-weight reference | Does not show distribution, muscle, or proportions |
| DEXA scan | Clinical imaging scan | Measured composition and bone data | Clinical or laboratory measurement | Requires equipment, appointment, and professional context |
| Skinfold calipers | Manual skinfold measurements | Body fat estimate from measured sites | Field estimate by a trained person | Sensitive to technique and consistency |
How accurate is a 3D Body Visualizer?
Formulas are accurate when inputs are accurate. The 3D shape is approximate because a measurement model cannot directly measure muscle, fat distribution, posture, bone structure, or genetics. Review the entered units and repeat any surprising measurement before comparing scenarios or interpreting a small visual difference. A 3D Body Visualizer is most useful when the measurement method stays consistent.
Privacy: no photo upload required
This tool works entirely from numeric measurements.
Measurements are processed for preview only and are not stored.
Frequently asked questions
What is a 3D Body Visualizer?
v
It estimates a 3D silhouette from measurements. It is not a scan, medical test, or photograph.
How accurate is a 3D Body Visualizer?
v
Arithmetic metrics are accurate to the entered values; the 3D silhouette remains an approximate model.
Can I use height and weight only?
v
Yes. They create a basic estimate; additional measurements make it more specific.
Can I compare current and goal body shapes?
v
Yes. Enter target values to view a side-by-side scenario, not a guaranteed outcome.
Does this tool store my measurements?
v
No. The core preview uses current-session numeric values without storing a personal image.
Is this medical advice?
v
No. Do not use it for diagnosis or treatment decisions; speak with a qualified professional.
Do I need to upload a photo?
v
No. The 3D Body Visualizer uses manually entered measurements.
This 3D Body Visualizer provides a general estimate from user-entered measurements. It is not medical advice and should not be used for diagnosis or treatment decisions.
