Pricing Sizer

Yes. Sizer extends WooCommerce single product pages and renders nothing without WooCommerce active. WooCommerce is declared as a required plugin. The plugin itself is free and GPLv2-licensed.

On the single product page, Sizer adds a “Size guide” button right after the add-to-cart button. Clicking it opens the chart in an accessible modal dialog. The button only appears on products that have a chart assigned.

Yes. You build a chart once under WooCommerce → Size Guides, then assign it on each product from the Product data → Size guide tab. The same chart can be assigned to any number of products. Assignment is done per product.

Yes. Sizer’s templates can be overridden from your theme by placing them in a sizer/ folder. The storefront stylesheet exposes CSS custom properties (accent colour, radius, dialog colours) you can re-theme. The stylesheet also ships dark-scheme and reduced-motion variants.

Yes. Sizer uses a native <dialog> element with a labelled heading, a close button and keyboard support. The dialog also respects the prefers-reduced-motion setting. It is screen-reader friendly.

Nothing is rendered. Sizer only adds the button and dialog when a product has a chart assigned. On products with no assignment the page is left untouched.

No. Sizer makes no external requests and loads no remote scripts or fonts. Charts and settings are stored in the sizer_charts and sizer_settings options, and each product’s assignment in _sizer_chart_id post meta. No data leaves your site.

Yes. Swatch shows variations as swatches and Shortlist adds a wishlist. Sizer complements the product page with a size guide.
