No one reads a screen top to bottom; eyes jump to whatever pulls hardest and negotiate from there. Visual hierarchy is the designer's side of that negotiation, deciding in advance what pulls first, second, and last. When hierarchy works, users think the product is simple; when it fails, they think they are tired.
In this glossary topic:

What is visual hierarchy?
Visual hierarchy is the arrangement of design elements so that their visual weight matches their importance, guiding attention through a layout in the intended order. It is one of the core principles of visual design: the mechanism that turns a collection of elements into a readable sequence of first this, then that.
How do designers create visual hierarchy?
Six levers do most of the work. Size, since larger reads as more important. Color and contrast, which pull attention regardless of position. Position, because top and left carry weight in left-to-right reading cultures. Spacing, where whitespace isolates and grouping relates. Typography, from weight to case. And motion, the strongest and most easily abused lever of all. Skilled hierarchy spends these levers sparingly: if everything is emphasized, the design has no hierarchy, only noise.
Why does visual hierarchy matter?
Hierarchy is the difference between users finding things and users searching for them. Strong hierarchy lowers cognitive load, speeds task completion, and quietly signals what the product considers important, which is a brand statement as much as a usability one. Weak hierarchy shows up in analytics as hesitation: longer times on simple screens, missed primary actions, and support questions the interface was supposed to answer.
