CS Size Chart

CS Size Chart is a WooCommerce plugin that allows store owners to create and display clear size charts for their products. It helps customers choose the correct size and reduces confusion by providing structured measurement information.

The plugin supports manual charts, templates, and an optional AI assistant for size recommendations. All AI features are disabled by default and only work if the store owner configures their own OpenAI API key.

The plugin follows WordPress coding standards, uses prefixed functions and classes, and does not send data to external services unless optional AI features are explicitly enabled.

Key Features

• Unlimited Size Charts – Create multiple charts for different categories or product types.
• Smart Assignments – Apply charts globally, by product category, or per product.
• Visual Table Builder – Build tables without writing code.
• Pre-Built Templates – Start quickly with common apparel templates.
• Responsive Layout – Charts adapt to mobile, tablet, and desktop screens.
• Flexible Display Options – Show charts as a tab, popup, or via shortcode.
• Optional Analytics – Track non-personal chart interactions and recommendation events (stored locally).
• Optional AI Fit Assistant – Generate size suggestions using the OpenAI API when enabled.

All AI-related functionality is optional, disabled by default, and only runs after an API key is provided and the features are explicitly enabled.

How It Works

1. Create a Size Chart

   • Go to Size Charts → Add New
   • Use the table builder or choose a template
   • Add descriptions or measuring instructions
   • Publish the chart

2. Assign the Chart

   • Globally for all products
   • By product category
   • Per individual product (override)

3. Display the Chart

   • As a WooCommerce product tab
   • In a modal popup
   • Using the shortcode: [cssc_size_chart id=”123″]

4. Analytics (Optional) If enabled, the plugin stores anonymized interactions such as:

   • Chart views
   • AI recommendation requests
   • Recommended sizes and confidence values

   No personally identifiable information is stored. All data remains in your WordPress database.

5. AI Size Quiz and Photo Measurements (Optional)

   • Size quiz collects height, weight, fit preference, and body shape
   • Optional photo-based measurement assists recommendations
   • Requires an OpenAI API key provided by the site owner
   • Features remain inactive unless manually enabled in settings
