Questions and answers
How is the difference calculated?
The absolute difference is the larger height minus the smaller height. Percentages use the first person as the stated reference.
Does the picture measure a person?
No. The silhouettes illustrate the heights you enter. They do not estimate height from photos or represent exact body proportions.
