The default choice
The default Miles option is usually the simplest place to start. Miles creates a custom theme foundation for your site, based on the brief and design direction you approve. Choose this when you care more about the result than about starting from a specific existing WordPress theme.When to choose a parent theme
Choose a parent theme when you already know you want the site built on top of one of the listed block themes, such as Ollie, Spectra One, Frost, Ona, or Twenty Twenty-Five. This can be useful when:- your team already likes that theme
- you want the site to fit an existing WordPress workflow
- you expect to keep editing within that theme’s patterns and style system
- a client or developer specifically requested it
