Speed & performance

Choosing a lightweight theme baseline without looking “cheap”

Updated 2026-04-11 · Practical guide for NZ small businesses

Short answer: Pick a theme with minimal required plugins, sane defaults, and active maintenance—speed and accessibility stem from structure, not only colours.

“Heavy” themes hide dozens of scripts behind demo imports that SMEs never disable.

Evaluation checklist

  • Demo with default assets disabled—measure weight.
  • Review changelog frequency and support responsiveness.
  • Check accessibility claims with quick keyboard tests.

Child themes

Preserve update paths—customise via child theme or CSS variables rather than hacking parent files.

Longevity

Favour themes that embrace block editor patterns you can sustain.

Frequently asked questions

Are free themes unsafe?

Not inherently—audit code source and update history like any software.

Can we switch themes later?

Yes—expect visual QA and possible block markup differences.
