Sizer Pro
Sizer Pro is the planned premium edition for Sizer. It is an add-on that requires the free Sizer plugin installed and active; it is distributed through Freemius (licensing, activation and automatic updates), not the WordPress.org directory.
The 0.1.0 release is an early scaffold: it ships the licensing, bootstrap, activation and database-migration plumbing that the premium features will hook into. The features below are planned and not yet implemented.
Planned PRO features
Section titled “Planned PRO features”- Per-variation charts — show a different chart depending on the variation the shopper selects.
- Unit switching — toggle the chart between cm and inch with one control.
- Find my size — a calculator that suggests a size from the shopper’s measurements.
- Import / export — move charts between stores or back them up as a file.
What the scaffold does today
Section titled “What the scaffold does today”- Boots only after the free Sizer plugin has loaded and fired its boot action.
- Verifies the free plugin is present and meets the minimum version, with admin notices when it is not.
- Registers premium services and hooks into the free plugin’s container (registries are empty placeholders for now).
- Runs version-tracked PRO activation defaults and database migrations.
- Declares WooCommerce HPOS and Cart/Checkout Blocks compatibility.
- Integrates the Freemius SDK for licensing, activation UI and automatic updates.
Relationship with Sizer
Section titled “Relationship with Sizer”Sizer Pro extends the free Sizer plugin. The free plugin provides the core reusable charts shown in an accessible modal or product tab; PRO adds per-variation charts, unit switching, a find-my-size calculator and import/export that fashion stores ask for.
