Jonathan Scott and Zooey Deschanel are not the only celebrity couples with a significant height difference between them. Dax Shepard and Kristen Bell, as well as Sacha Baron Cohen and Isla Fisher, are examples of other celebrity couples with about a foot of difference in their heights.
A difference in height can be an important factor to some people on the dating scene. Sociologist Dr. Jess Carbino built her career focused on the world of online dating. Carbino posits that there may be a few psychological and biological reasons behind gravitating to someone of a taller stature. Typically, women who date men may choose a taller partner over a shorter one based on the assumption that they are healthier. And this may actually be true in some cases, according to a study published in the American Journal of Human Biology. Plus, a taller person may be more likely to be successful and make more money due to the confidence and perception of dominance that often comes with being a tall man.
Whether or not their height difference is one of the things that drew Jonathan Scott and Zooey Deschanel to each other, their relationship seems to be one that will last — even if they have to constantly adjust the driver's seat.
