Where the F-pattern shows up on dense text, the Z-pattern describes eye flow on sparse, whitespace-heavy screens like landing pages. It's a rule of thumb rooted in left-to-right, top-to-bottom reading habits — not one researcher's finding, but a convention the web design industry converged on.
A typical layout: logo top-left, nav/CTA top-right, eyes drop diagonally to supporting copy bottom-left, and land on the final CTA bottom-right — placing the conversion button exactly where attention naturally arrives.
The dot below traces the Z path, and the button it lands on lights up at the end.
When to use
Use this for sparse screens like landing pages and hero sections. Once the page gets text-heavy, the flow shifts toward an F-pattern — don't mix the two assumptions.
