Getting started

Most shops can show their first size guide in a few minutes. Build a chart once, assign it, pick the placement.

Before you start

• WordPress 6.5 or newer
• WooCommerce active
• PHP 8.1 or newer

Install

1. Install WooCommerce and make sure it is active.
2. Install Sizer from the plugin directory (when live on WordPress.org) or upload the sizer folder to /wp-content/plugins/.
3. Activate the plugin.

First configuration

Open WooCommerce → Size Guides in wp-admin:

• Create a chart — a simple labelled table of rows and columns; build it once and reuse it.
• Display style — accessible <dialog> modal or an inline product tab.
• Trigger style — button or text link.
• Placement — after or before the add-to-cart button, in the product summary or meta area, or as a product tab.

Then assign the chart on a product (Product data → Size guide) or on a product category so every product in it inherits the chart.

Verify on the storefront

1. Open a product that has a chart assigned — the trigger (button or link) should appear in your chosen placement.
2. Click the trigger — the chart should open in the accessible modal, or show inline if you picked the tab.
3. Keyboard test — open the modal, tab through it, and close with Escape; focus should be managed correctly.
4. Open a product with no chart — nothing should render.

Category defaults

Assign a chart to a product category and every product in it inherits the chart, unless the product has its own assignment.

Free vs PRO

The free edition covers reusable charts, per-product and per-category assignment, modal or product tab, and configurable trigger and placement.

Sizer PRO adds per-variation charts, unit switching (cm/inch), a “find my size” calculator, import/export and more — not the basic size guide.
