Klein Sexual Orientation Grid

  The Klein Sexual Orientation Grid: A Modern View of Human Attraction

The Klein Sexual Orientation Grid (KSOG) is a psychological tool developed by Dr. Fritz Klein in the 1980s to better understand the complexities of sexual orientation. Unlike earlier models, which viewed sexuality as fixed or binary, the Klein Grid introduced a more fluid and multidimensional approach—acknowledging that attraction, behavior, and identity can evolve over time.

The KSOG expands on Alfred Kinsey’s original scale by evaluating sexual orientation across seven dimensions—including attraction, behavior, fantasies, emotional preference, and self-identification—each measured over three different time periods: past, present, and ideal. This model helps researchers and individuals explore how sexuality may shift based on experience, social context, or emotional connection.

Why the Klein Grid Matters Today

The Klein Grid remains an important tool for studying human sexuality because it challenges rigid labels and binary thinking. Instead of defining people as strictly heterosexual, homosexual, or bisexual, it recognizes the spectrum of sexual experience.

In modern discussions about gender and attraction, the KSOG supports a more inclusive understanding of identity. It helps illustrate that human sexuality isn’t static—it’s dynamic, contextual, and deeply personal. Whether used in academic research or self-reflection, the Klein Grid continues to inspire open dialogue about how attraction truly works.
