F-Pattern / F-Shaped Reading Pattern

CORE DEFINITION

The F-pattern is a reading behavior identified by the Nielsen Norman Group through eye-tracking studies of web users. The eye first sweeps horizontally across the top of the content area, then moves down and sweeps horizontally again over a shorter distance, then scans vertically down the left edge. The shape emerges because readers scan for relevance rather than reading linearly, and they abandon a line once it stops promising value. The pattern is more pronounced on text-heavy pages and less so where visual hierarchy or subheadings are strong. Its practical implication is that placement on the page determines whether content is seen at all.
