WPC Product Size Chart for WooCommerce: worth using, but premium is harder to justify

WPC Product Size Chart for WooCommerce is a useful utility, not a must-have upgrade. It solves one specific problem: showing customers a measurement table or sizing guide beside the products they are considering. For clothing, footwear, accessories, furniture, or any catalog where dimensions affect the purchase decision, that can be genuinely valuable. The plugin supports unlimited charts, popup display, shortcodes, custom rows and columns, images, text, units, and nine placement positions on single-product pages. Those are practical features rather than marketing decoration. ([wpclever.net](https://wpclever.net/downloads/wpc-product-size-chart/))

Its strongest feature is the distinction between global and individual charts. A global chart can be assigned across products using sources such as categories, tags, product attributes, shipping classes, visibility, and product type. Individual charts can then be added or overridden from a product’s own Size charts tab. That makes it possible to apply one general clothing chart across a catalog while giving a particular brand, shoe line, or garment its own measurements. The documentation also confirms that charts can be combined in one popup, which is useful when shoppers need both a body-measurement guide and a fit explanation.

The free version is therefore more capable than many basic size-chart plugins. If you have a small store and only need a table linked from the product page, it should do the job without forcing you into a paid plan. Shortcode support is especially helpful when the automatic insertion point does not fit your theme. The developer documents the [wpcsc_link] shortcode as a fallback for placing the chart manually.

The premium upgrade is less universally attractive. The main functional addition is the Combined source, which lets you build more complicated rules from multiple conditions. That matters for a large catalog, such as showing a chart only for products in a category with a specific tag while excluding hidden items. The official price is $29 for one site, $59 for up to five sites, and $99 for unlimited sites, while premium also includes customization support and lifetime plugin updates. ([wpclever.net](https://wpclever.net/downloads/wpc-product-size-chart/)) For a simple store, that is difficult to justify when the free edition already handles ordinary global and product-specific charts.

There are also signs that the frontend experience needs testing rather than blind trust. WordPress.org users have reported popup duplication after clicking the chart link repeatedly, slow popup opening, missing close-button icons, text-wrapping problems, and conflicts involving Divi and product tabs. One recent reviewer specifically reproduced the duplicate-popup issue on the developer’s demo and worked around it with CSS that disables pointer events while the button loads. The support forum shows that these are recurring integration concerns, even though the developer has generally replied to threads.

Compared with YITH Product Size Charts for WooCommerce, WPC offers similarly broad chart assignment and popup or tab display, but YITH presents more frontend styling, bulk editing, widgets, printing, and tabbed-popup controls in its feature set. Compared with WooCommerce Product Size Charts & Guides, WPC offers more product-source logic through its Combined source, while WooCommerce’s extension emphasizes user-role targeting, extra tabs, previews, cloning, and detailed design controls. ([yithemes.com](https://yithemes.com/themes/plugins/yith-product-size-charts-for-woocommerce/?utm_source=openai)) The verdict is simple: use WPC if you want flexible chart rules at no cost, but choose YITH or the official WooCommerce extension when presentation quality and structured support matter more than price.
