Density
The amount of information presented per unit of screen space, set by type size, spacing, and how many elements share the view at once.
Example usage
“A trading dashboard earns its density — traders want forty signals on screen, not four cards.”
Editor’s note
Density is a contract with the user, not a failure of design. Power tools — terminals, spreadsheets, consoles — should be dense; onboarding should not. The mistake is uniformity: consumer airiness applied to expert tools, or expert density on a first-run screen. Density and whitespace are the same dial read from opposite ends.
