The 3D body visualizer height and weight tool needs 2 numbers. The tool opens on a male figure of 180 cm (5 ft 11 in) and 80 kg (176 lb), which is a body mass index (BMI) of 24.7. A dot marks that body on a height and weight chart, and the dot moves as the numbers change.
How the 3D body visualizer height and weight tool works
The 3D body visualizer height and weight tool works in 2 steps. Height scales the figure from the floor to the top of the head. Weight sets the volume of the figure: the tool divides the weight by a body density and sizes the figure to hold that many liters.
For 180 cm and 80 kg the density is 1.052 kg per liter, so the male figure holds 76.0 liters. The model then estimates every tape measurement: a 100.6 cm chest, an 84.4 cm waist and 99.4 cm hips.
The chart plots weight against height. Each colored area is one BMI category of the CDC.
| CDC category | BMI | At 180 cm (5 ft 11 in) |
|---|---|---|
| Underweight | Below 18.5 | Below 59.9 kg (132 lb) |
| Healthy weight | 18.5 to under 25 | 59.9 kg to 80.7 kg (132 lb to 178 lb) |
| Overweight | 25 to under 30 | 81.0 kg to 96.9 kg (179 lb to 214 lb) |
| Obesity | 30 or more | 97.2 kg (214 lb) or more |
The CDC calls BMI a screening measure. BMI does not distinguish between fat, muscle and bone mass, so the category describes the 2 numbers and not a person's health. For your own health, a doctor or nurse can assess you in person.
3D body visualizer height and weight formula
The 3D body visualizer height and weight tool uses 2 formulas: BMI for the category and volume for the figure.
| Formula | For the opening figure |
|---|---|
| BMI = weight in kg ÷ height in m, squared | 80 ÷ (1.80 × 1.80) = 24.7 |
| Body fat percent = 1.20 × BMI + 0.23 × age − 10.8 × sex − 5.4 | 1.20 × 24.7 + 0.23 × 30 − 10.8 − 5.4 = 20.3 |
| Density in kg per liter = 495 ÷ (body fat percent + 450) | 495 ÷ 470.3 = 1.052 |
| Volume in liters = weight ÷ density | 80 ÷ 1.052 = 76.0 |
The body fat formula is the one Deurenberg, Weststrate and Seidell published in 1991. Sex is 1 for men and 0 for women, and the tool holds age at 30. The density formula treats the body as two parts, fat and everything else, and the US Navy's body fat reports credit the formula to Siri (1961). The tool uses both formulas only to size the figure. The body fat number is not a measurement of anyone.
In feet and pounds the tool converts first: 1 inch is 2.54 cm and 1 pound is 0.4536 kg.
3D body visualizer height and weight conversion chart
The 3D body visualizer height and weight tool lists, for the height entered, the weights that give a BMI of 18.5 to 24.9. The chart gives the same range for 10 heights.
| Height | In feet and inches | Weight at BMI 18.5 to 24.9 | In pounds |
|---|---|---|---|
| 150 cm | 4 ft 11 in | 41.6 to 56.0 kg | 92 to 124 lb |
| 155 cm | 5 ft 1 in | 44.4 to 59.8 kg | 98 to 132 lb |
| 160 cm | 5 ft 3 in | 47.4 to 63.7 kg | 104 to 141 lb |
| 165 cm | 5 ft 5 in | 50.4 to 67.8 kg | 111 to 149 lb |
| 170 cm | 5 ft 7 in | 53.5 to 72.0 kg | 118 to 159 lb |
| 175 cm | 5 ft 9 in | 56.7 to 76.3 kg | 125 to 168 lb |
| 180 cm | 5 ft 11 in | 59.9 to 80.7 kg | 132 to 178 lb |
| 185 cm | 6 ft 1 in | 63.3 to 85.2 kg | 140 to 188 lb |
| 190 cm | 6 ft 3 in | 66.8 to 89.9 kg | 147 to 198 lb |
| 195 cm | 6 ft 5 in | 70.3 to 94.7 kg | 155 to 209 lb |
To see more than one weight at a time, line up one height at five weights. To add tape numbers to the 2 numbers, open the figure with its tape lines on. The BMI visualizer shows one height at every BMI category.
