Based on Dr. Fritz Klein's Sexual Orientation Grid, which is an expansion of the Kinsey scale, this grid attempts to measure sexual orientation. It also provides a different way of thinking about sexual orientation, as something that fluctuates and varies rather than remaining static.

The Fritz Klein Sexual Orientation Grid takes the original Kinsey scale, a 0-6 rating of sexual orientation, and applies it to seven different factors divided into three time periods.

The point of the grid is not to come up with an "answer." Unlike a mathematical problem, the grid is simply designed to explore orientation in a more complex and detailed manner.
