The F-pattern comes from eye-tracking research by the Nielsen Norman Group. When users encounter text-heavy pages, their eyes trace a shape resembling the letter F: a horizontal sweep across the top, a shorter horizontal sweep partway down, then a vertical scan along the left edge. Most of the right side of the page gets ignored.
This has direct implications for landing pages: your most important content belongs in the top-left area, key information should be front-loaded in each line of text, and the left margin is prime real estate for bullets, icons, or headings that catch the vertical scan. Burying your value proposition on the right side of a text section is asking for it to be missed.
F-pattern vs. Z-pattern: which applies?
The F-pattern dominates on text-heavy pages — blog posts, long-form content, FAQ sections. For visual landing pages with hero images, alternating image-text sections, and prominent CTAs, the Z-pattern is more relevant. Most landing pages are actually Z-pattern in the hero and F-pattern in the detail sections below.
Don't fight the F-pattern — exploit it. Put benefit statements at the start of bullet points (not the end). Use left-aligned headings, not centered ones, for content sections. And never put a standalone CTA on the far right of a text block without surrounding visual weight to draw the eye. The scan will skip right past it.
