Options
Default (420×580)
Standard widget size. Works on most sidebars and blog layouts.
Compact (340×520)
Smaller footprint for tight layouts or mobile-first designs.
Wide (500×580)
More breathing room for full-width content sections.
Centred Wrapper
Includes a flex wrapper to centre in any container.
Note

The allow="cross-origin-isolated" attribute is recommended — it enables PerformanceResourceTiming inside the iframe, which is used for accurate ping measurement. Without it, ping may read slightly higher in some browsers.
