Size Guide for WooCommerce lets you create clean size charts and show them on your product pages in a popup or a product tab. Shoppers pick the right size with confidence, so you get fewer questions and fewer returns.
Build a chart once and reuse it: assign it to a single product or to a whole category. The plugin is lightweight, object-oriented PHP on standard WooCommerce hooks.
A simple chart editor
A Size guides screen under Products, with a spreadsheet-style table editor
Add or remove rows and columns, header row styled automatically
Optional note under the table, and a cm / inch switch for charts entered in centimetres
Up to 40 rows and 12 columns per chart
Shown where shoppers need it
A Size guide button above the Add to Cart button, right below the size options, opening a popup
Or a Size guide tab on the product page, or both
Responsive: the table scrolls on small screens
Accessible: focus stays in the popup and Esc closes it

A product's own guide overrides the category, and "No size guide" switches it off

Frequently asked questions
How do I create a size chart?+
Go to Products → Size guides → Add size guide. Edit the table (the first row is the header), optionally add a note and the cm / inch switch, and publish.
How do I show it on a product?+
Edit the product and pick the guide in the Size guide box, or assign a guide to a product category so all its products use it.
Which wins, the product or the category guide?+
The product's own guide. Choose No size guide on a product to hide the category guide for it.
Does it work with variable products?+
Yes. The Size guide button appears right below the variation options, above the quantity and Add to Cart button.
Can I show the chart in a tab instead of a popup?+
Yes. Choose Product tab, or Both, in the settings.
How does the cm / inch switch work?+
Enter measurements in centimetres and tick the switch option. Shoppers can toggle to inches and the numbers (including ranges like 86-91) are converted.
Can I place a chart anywhere?+
Yes. Use the shortcode [tqsg_guide id="123"] or link to #tqsg-123 on a product page.
Is any customer data stored?+
No. Only plugin settings and your size guides are saved.
