Use cases

  • Sharper visual assets

    Serve denser imagery or refined decoration when display density makes the extra detail worthwhile.

  • Print and output tuning

    Adjust styles for environments where output resolution changes the expected presentation.

Cautions

  • Resolution alone does not tell you everything about screen size or reading distance.
  • Prefer semantic responsive media features when they solve the asset problem more directly.

Accessibility

  • Sharper assets can help readability, but text should remain real text whenever possible.
  • Do not gate essential information behind image quality improvements that only some screens receive.
