Designing from the smallest screen forces priority decisions that improve every size.

Principles#

Start each screen as a 375px single column. Every desktop affordance must survive the squeeze test. Thumbs own the bottom third: put primary actions there.

Applied#

  • Apply it to your next feature, not a mythical redesign
  • Encode the decision as a token or component
  • Write one paragraph of team guidance
  • Audit an existing page against the principle
