How the F‑Pattern Shapes UI Design: Insights from Eye‑Tracking

Before the article begins, a quick test asks readers to choose the most comfortable reading order for a set of numbers, revealing a preference for the traditional left‑to‑right, top‑to‑bottom sequence (Image 1).

Next, an eye‑tracking heatmap (Image 2) shows that users spend the most time in the upper‑left area of a page, indicated by red zones, while blue zones receive less attention.

Based on a 2006 Nielsen Norman study of 232 users browsing thousands of websites, the "F‑shaped" reading model was identified: users scan horizontally across the top, then move down the left side, creating an overall shape resembling the letter F.

The article then applies the F‑model to UI design using the Fangduoduo real‑estate app as an example (Image 3). By mapping the page’s visual flow, designers can identify which elements convey the most important information, such as the highlighted "Start Searching" button placed in the prominent visual hotspot.

Analyzing the app’s homepage (Image 4) shows that the first eye‑catching element is the "Start Searching" button, which disrupts the typical F‑pattern but intentionally draws attention as a visual focal point.

The text explains that while users naturally read left‑to‑right and top‑to‑bottom, they are also attracted to standout elements—visual focal points—that designers use to guide actions. Emphasizing these points with size, color, or animation can significantly capture user attention.

Beyond static focal points, dynamic cues like the pulsing "hot" bubble in the news module or the shaking "promotion" badge (Image 5) further attract users and add interactivity.

In summary, understanding the F‑pattern helps designers categorize content according to user reading habits, place the most important information in high‑attention (red) zones of a heatmap, and combine visual focal points with motion, color, position, and size to create a clear visual hierarchy and improve the reading experience.
