Why Users Scan Pages in an “F” Shape and How to Design for It

Most users read from left to right and top to bottom, similar to Western habits. Analyzing browsing modes, paths, and page layouts can help optimize layout for better reading efficiency and experience.

1. “F”‑shaped Browsing Pattern

The F pattern appears when users scan long texts on web or mobile, moving horizontally across the top, then lower horizontal scan, and finally a vertical scan down the left side. Design tips:

Users scan, not read each word, so key information may be missed.

The first two paragraphs are critical; their quality influences continued browsing.

Place keywords early in titles, subtitles, and paragraph openings.

The F pattern suits most scenarios, allowing quick scanning for key information.

2. “Z”‑shaped Browsing Pattern

The Z pattern follows a left‑right, top‑bottom path resembling the letter Z, suitable for pages where text blocks are not the main focus. Important information should be placed at the start and end points (positions 1 and 4) to guide the eye naturally.

3. Commitment (Focused) Browsing Pattern

This pattern involves careful, thorough reading of most or all text, usually driven by a task or strong interest, such as studying for an exam or completing a work assignment.

4. Marking (Spot) Browsing Pattern

Users focus on highlighted keywords—bold, colored, or otherwise emphasized—creating a spot‑like heat map on the page.

5. Layer‑Cake Browsing Pattern

When an article contains headings, subheadings, or bold text, users concentrate on these prominent sections, quickly forming a layered‑cake‑like visual hierarchy.

6. Comparative Thinking

Comparing Z‑type and left‑aligned layouts shows that both guide users similarly: the first prominent image captures attention, then eyes move between text and images. Decorative images with little information are often ignored, while informative images retain attention.

7. Summary

The F pattern fits text‑heavy pages; the Z pattern suits general layouts; patterns may be nested based on context.

Pages with images attract more interest; informative images outperform decorative ones.

For informative images, both aligned and Z layouts work well.

Decorative images should be aligned to avoid distracting users; Z layouts can increase image exposure.

Place high‑information images on the left side of the first line; avoid decorative images at the top or left.

Align decorative images with text height to prevent eye‑capture.

Consider adding a “back to top” button for easier navigation after scrolling.
