Typography Scale
Plain-language definitionA limited set of text sizes and line heights used to create consistent hierarchy. A good scale accounts for reading length, screen size, and content variation.
Why it matters
Use the term to make a better decision.
In practice, typography scale matters when a team needs to connect a technical or creative choice to a visible change in clarity, performance, discovery, or conversion. The useful question is not whether the term sounds sophisticated. It is what decision it helps the team make.
