Performance

Performance is a design decision, not a final-week task

Most of a page's weight is committed the moment the layout is approved — long before anyone opens Lighthouse.

Speed work at the end of a project is mostly damage limitation. The decisions that set a page's weight — how many typefaces, how much imagery, whether the hero is a video, how many third-party scripts the marketing stack needs — are all made during design.

The four questions worth asking during design

  • 01How many typeface weights does this design actually use?
  • 02Does the hero need media, or does it need a strong idea?
  • 03What is the single largest image on the page, and how large is it really?
  • 04Which third-party scripts are load-bearing, and which are habits?

None of these are engineering questions. They are all answerable in a design review, which is the cheapest place to answer them.
