How this list was compiled: Every name checked on 2026-10-02 and kept only where two of these use it. (1) Communication in the Real World: An Introduction to Communication Studies, section 6.4, Self-Disclosure and Interpersonal Communication, an openly licensed textbook read in the LibreTexts copy (a window with four panes; one axis is what is known to us and the other what is known to others; the upper left pane holds open information, known to us and to others; the bottom left pane hidden information, known to us but not to others; the upper right pane information known to others but not to us, the blind area; the bottom right pane the unknown area; its figure prints Known to Self over the window and Known to Others beside it; by self-disclosure, hidden information becomes open; the window is named after its creators). (2) Wikipedia, Johari window (four quadrants: open, known to self and to others; blind, others know it, self does not; hidden, self knows it, others do not; unknown, known neither to self nor to others; the second names arena, blind spot and facade; the name combines the creators' first names; the text gives no position for a pane). (3) Joseph Luft, The Johari Window: A Graphic Model of Awareness in Interpersonal Relations, a 1982 reprint of the article by one of the window's two creators (its Figure 1 prints Known to Self and Not Known to Self over the two columns and Known to Others and Not Known to Others beside the two rows, with the area of free activity upper left, the blind area upper right, the avoided or hidden area lower left and the area of unknown activity lower right; the text also writes the hidden area and the unknown area). (4) Ø. Kvalnes, Communication Climate at Work, 2023, an open-access book, chapter 5 and Table 5.1 (arena, known to the person and to others; blind spot, unknown to the person but known to others; facade, known to the person and not shared with others; unknown).

How it works

To label the parts of the Johari window, name its four panes, open, blind, hidden and unknown, and the two sides that sort them: what is known to self and what is known to others.

Read the full guide

Read the two sides

Over the columns, one person beside an open eye marks what is known to self, and the eye with a line through it marks what is not. Beside the rows, a group of people marks what is known to others and what is not.

Name the four panes

Each pane is where a column meets a row. Open: self and others both know it. Blind is known to others, not to self. Hidden: self knows it, others do not. Unknown is known to neither.

Print it

Print blank, under More options, gives the empty window to fill in.

The quiz also takes arena for the open pane, blind spot for blind and facade for hidden.

Questions and answers

What are the four parts of the Johari window?

Four panes: open, blind, hidden and unknown. Open is known to self and to others, blind: others know, self does not; hidden: self knows, others do not, and unknown is known to neither.

What is the blind spot in the Johari window?

The blind pane: what others know about a person that the person does not know. For example, others may see someone as a leader when that person is unaware of it.

What is the hidden area of the Johari window?

What a person knows about themselves and others do not. It is also called the facade. Self-disclosure, telling others about yourself, moves information from the hidden pane to the open pane.

Why is it called the Johari window?

The name joins the first names of its two creators, Joseph Luft and Harrington Ingham.
