WooCommerce has no built-in way to show a size chart on a product page. If you sell clothing, shoes, or anything else where fit varies by brand, that gap shows up fast in return requests. Four real plugins solve this without custom code: Sizor Product Size Chart For WooCommerce, Product Size Charts Plugin for WooCommerce, WPC Product Size Chart for WooCommerce, and SizeSync. The short version: Sizor gives you the most display placements, the Dotstore plugin lets you assign one chart to an entire category in a single action, WPC packs in the most granular placement options and lets you combine charts, and SizeSync skips chart-building entirely by shipping pre-made guides for 40+ product types.
This is a narrower question than “best WooCommerce plugins,” which is where most general coverage of this topic stops. A size chart is a specific product-page feature with its own setup quirks: some plugins build the chart per product, some assign by category, and one skips manual chart-building altogether. The comparison below is built from each plugin’s own WordPress.org listing, not a guess from its name or a marketing tagline.
| Plugin | Best for | Price | Last updated |
|---|---|---|---|
| Sizor Product Size Chart For WooCommerce | Most display placements (popup, tab, before add to cart, shortcode) | Free, Pro from $29 for 6 months (1 site) | August 22, 2026 |
| Product Size Charts Plugin for WooCommerce | Assigning one chart to a whole category at once | Free, Pro from $179/year | February 5, 2026 |
| WPC Product Size Chart for WooCommerce | Granular placement and combining multiple charts in one popup | Free, Pro one-time from $29 | September 13, 2026 |
| SizeSync | Pre-built size guides with no manual chart-building | Free | June 2, 2026 |
Sizor Product Size Chart For WooCommerce
Sizor Product Size Chart For WooCommerce, built by VillaTheme, is a straightforward chart-builder: you create a table with as many rows and columns as you need, style it, and attach it to a product or category.
- Price: Free, Pro from $29 for 6 months on 1 site (or $49/year)
- Requires: WordPress 5.0+, PHP 7.4+
- Last updated: August 22, 2026
The plugin ships with a handful of ready-made templates for common categories (T-shirts, dresses, shoes), which you can duplicate and edit rather than starting from a blank table every time. Its real differentiator against the other three options here is display flexibility: a chart can show as a popup, as a dedicated product tab, right before the add-to-cart button, or dropped anywhere on a page via shortcode. You can also import a chart from a CSV file, which matters if you’re migrating chart data from a spreadsheet you’ve already built or moving it off another platform.
Setup is standard WordPress plugin installation: upload the plugin folder to wp-content/plugins (or install it by name from the Plugins screen) and activate it. From there you build a chart, choose colors for the header row and alternating rows, pick which of the four display modes to use, and assign the chart to specific products or categories from the chart’s own edit screen.
The one caveat worth flagging comes straight from the plugin’s own readme: VillaTheme states the plugin “works based on WooCommerce 7.x,” which is a narrower compatibility statement than the other three plugins make about their WooCommerce support. If your store is running a much newer or older WooCommerce release, it’s worth testing this one on staging before committing to it.
Product Size Charts Plugin for WooCommerce
Product Size Charts Plugin for WooCommerce, built by Dotstore, leans into breadth: it ships with around 15 ready-made templates covering men’s and women’s shoes, shirts, jeans, dresses, coats, and more, styled in four presets (Minimalistic, Classic, Modern, Default).
- Price: Free, Pro (Personal) from $179/year for 1 site, Business from $399/year for 5 sites
- Requires: WordPress 5.0+, PHP 7.2+
- Last updated: February 5, 2026
The feature that sets this one apart from Sizor and WPC is category-wide assignment: instead of attaching a chart to products one at a time, you can apply it to an entire WooCommerce category in a single action, which matters if you’re running a store with hundreds of SKUs in the same size system. It also supports conditional assignment by product attribute, and lets you export a finished chart and import it on a second site, useful if you manage more than one WooCommerce install.
Installation follows the usual pattern: upload the plugin folder to wp-content/plugins or install the zip through the WordPress admin, then activate it. Once active, you build a chart from scratch or duplicate one of the built-in templates, decide whether it shows in an additional product tab or a popup, and assign it to a single product, a group of products, or a whole category.
The honest limitation here is price and update cadence. The Pro tier is billed annually and starts well above what the other three plugins charge for a comparable feature set, and the free version was last updated in February 2026, seven months before this comparison was written, the longest gap of any plugin on this list. It’s not stale enough to call abandoned, but it’s the one to watch if you need frequent WooCommerce compatibility updates.
WPC Product Size Chart for WooCommerce
WPC Product Size Chart for WooCommerce, built by WPClever, is the most actively maintained plugin in this comparison and the one with the most placement control.
- Price: Free, Pro one-time payment from $29 for 1 site, $59 for 5 sites, or $99 for unlimited sites (lifetime updates)
- Requires: WordPress 5.9+ (PHP version not specified by the plugin)
- Last updated: September 13, 2026
Where this plugin pulls ahead is placement: it offers nine positions for where the size chart link appears on a single product page, versus the handful of fixed spots the other plugins offer. It also supports two chart types, global charts reused across many products and individual charts built for one product, and it can combine several charts into a single popup, which is useful if a product needs both a clothing size chart and a separate measurement guide shown together.
Setup is more specific than a generic install-and-activate: search for “WPC Product Size Chart” from Plugins > Add New, install and activate it, then go to WP-admin > Size Charts to build your global charts. When you’re editing an individual product, a “Size Charts” tab appears on the product edit screen where you attach one or more charts directly to that product.
The real limitation is that the free version’s global charts can’t pull from more than one source at once. WPClever’s own description lists “Combined Sources for global size charts” as a Pro-only feature, so if you need one chart to reference data assembled from multiple templates, that specific capability sits behind the paid tier. Its one-time pricing (rather than the annual billing the other paid plugins use) is worth factoring into a long-term cost comparison too.
SizeSync
SizeSync takes a different approach entirely: instead of asking you to build a chart, it ships with pre-made size guides for over 40 product categories across men’s, women’s, footwear, kids and baby, and accessories, in eight size systems (UK, USA, EU, Italy, France, Japan, Korea, China).
- Price: Free
- Requires: WordPress 5.8+, PHP 7.4+
- Last updated: June 2, 2026
The differentiator is auto-detection: rather than attaching a chart to each product, you map a WooCommerce category to a size guide once, in the plugin’s “Assign to Categories” screen, and every product in that category automatically shows the matching guide. For a store where sizing is consistent within a category, that’s a meaningfully faster setup than building or assigning a chart product by product.
Setup: activate the plugin with WooCommerce already running, go to SizeSync in the WordPress admin sidebar, set your store’s brand name and default size system under General Settings, then go to Assign to Categories and map each WooCommerce category to one of the built-in guides. No chart design step is required.
SizeSync is newer than the other three plugins here, first listed on WordPress.org in June 2026, so it has less real-world testing behind it. The tradeoff for its speed is flexibility: because it works from predefined templates rather than a blank table, it’s not the right fit if your products need fully custom measurements that don’t map to one of its built-in categories, a hand-cut leather good or a made-to-order furniture piece, for instance. For standard apparel and footwear sizing, that’s rarely a problem.
How to pick
- If your sizing is standard across a category (regular clothing or shoe sizes) and you want the fastest setup, use SizeSync and skip building a chart entirely.
- If you’re assigning the same chart to hundreds of products in one category and want to do it in a single action, use Product Size Charts Plugin for WooCommerce.
- If you need a chart to appear in an unusual spot on the page, or you want to combine more than one chart into a single popup, use WPC Product Size Chart for WooCommerce.
- If you want the widest range of display modes (popup, tab, before add to cart, or shortcode) plus the ability to import chart data from a CSV, use Sizor Product Size Chart For WooCommerce.
For a size chart that needs to pull live data (say, from a separate sizing database or a fit-recommendation engine you’ve already built), a plugin comparison stops being useful and it becomes a custom development question. Our WooCommerce Development team builds that kind of integration directly when an off-the-shelf plugin’s assignment model doesn’t match how your catalog is actually structured. That’s the same off-the-shelf-versus-custom line we’ve walked through before for WooCommerce product bundles, and it applies here too: most stores don’t need custom code for a size chart, but a few genuinely do.
FAQ
Does WooCommerce have a built-in size chart feature?
No. WooCommerce core has no size chart or size guide functionality. Adding one requires a plugin or custom development, the same way WooCommerce has no built-in quick view feature either.
Which of these WooCommerce size chart plugins is completely free?
SizeSync has no paid tier as of this writing. The other three, Sizor, Product Size Charts Plugin for WooCommerce, and WPC Product Size Chart, are free to install with an optional paid upgrade for extra features.
Can I apply one size chart to an entire product category instead of setting it up per product?
Yes. Product Size Charts Plugin for WooCommerce lets you assign a chart to a whole category in one action, and SizeSync assigns by category by default since it maps guides to categories rather than individual products.
Will adding a size chart plugin slow down my WooCommerce store?
All four plugins here only load their chart assets on product pages where a chart is assigned, not sitewide, so the performance impact is limited to the pages that actually show one. As with any plugin, it’s worth checking page load time before and after activation on your own store rather than assuming.
Do I need a size chart plugin if I only sell one or two clothing items?
Probably not. For a handful of products, a size chart built directly into the product description with a WooCommerce native table or image is usually simpler than installing and maintaining a plugin. These plugins earn their keep once you’re managing charts across dozens or hundreds of SKUs.
