The four panes of the Johari Window will always remain the same size for all relationships or interpersonal encounters of a person.

The size of the panes in the Johari Window can change depending on the level of trust and communication within a particular relationship or group setting. As trust and communication increases, the Open area can become larger, while the Blind and Hidden areas can become smaller. Therefore, the size of the panes can vary depending on the interpersonal dynamics of each specific situation.
