Trapp family measurements

The family was officially measured back in December 2020 by Dr. Anna Sudo, an orthopedics doctor. In order to get an accurate measurement of Adam's height, Sudo had to stand on a step-ladder.

In order to get the most accurate measurement, each family member was measured three different times during the same day. Each time they were measured, they did so standing up and laying down. The numbers were averaged together to calculate the most accurate height.

While being tall has its advantages (each of the Trapp kids were recruited to colleges to play either basketball or volleyball), they say that being so tall has its downsides. For example, Savanna says that she had a very painful growth spurt where she grew about an inch-and-a-half in one month.

Also, shopping can be difficult, as well as fitting in most cars, the family told Guinness.
