Unclear sizing costs sales and creates returns. A clear size guide removes doubt, increases conversions, and cuts support and shipping costs. This rewrite explains three simple ways to add size charts to WooCommerce: a free plugin, a premium plugin with templates and bulk assignment, and a page-builder approach for custom product layouts.

TL;DR: If you need a budget option, use WPC Product Size Chart (free). For template libraries, advanced rules, and bulk assignment, use Advanced Product Size Charts Pro. For full layout control and branded product pages, build size guides into templates with SeedProd.

Why add a size chart?
– Fewer returns and lower shipping costs from incorrect-sizing orders.
– Higher conversion rates because shoppers feel confident about fit.
– Fewer measurement-related support tickets.
– Better mobile experience when charts are responsive or shown in popups.
– Improved product detail that can help SEO.

Which method fits your store?
– Method 1: Free plugin — best for stores on a tight budget.
– Method 2: Premium plugin — best for stores with many SKUs that need templates and bulk rules.
– Method 3: Page builder — best when you want full control of product page layout.

Prerequisite: An active WooCommerce store with products already added.

Method 1 — Free plugin (WPC Product Size Chart)
1. Install and activate WPC Product Size Chart for WooCommerce from the plugin directory.
2. Open Size Charts » Add New and give the chart a name (for example, Women’s Shoe Sizing).
3. In Configuration, either upload a manufacturer image (Add Media) or build a responsive text table using Chart Table for better mobile readability.
4. Use the grid to add rows and columns and fill in measurements.
5. Assign the chart with the Apply dropdown: target categories to show charts automatically, or leave as None and assign per product under the Size Charts tab in Product Data.
6. Publish. The plugin adds a Size Chart button that opens a popup on product pages.

Tips: Prefer text-based tables for accessibility and mobile legibility. Add a short “How to measure” note and both metric and imperial units.

Method 2 — Premium plugin (Advanced Product Size Charts Pro)
Why use it: Includes ready-made templates, modal popups, and flexible bulk assignment by category, attribute, tag, or product.
Steps:
1. Purchase, install, and activate Advanced Product Size Charts Pro.
2. Go to Size Chart » All Size Charts and choose a template (for example, Men’s T-Shirt).
3. Edit the template: double-click cells to change numbers, use the + control to add sizes or measurement rows, and delete unused rows with the trash icon to avoid blank lines.
4. In Size Chart Settings set Position to Modal Popup and customize link title, icon, font sizes, etc.
5. Assign charts using the meta boxes: Assign Category to target whole categories or Assign Product for individual items.
6. Publish and test the button and popup on both desktop and mobile.

Tips: Use the bulk assignment controls to apply consistent charts across collections. Test popups on small screens to ensure legibility.

Method 3 — Page builder (SeedProd, Elite license required)
Why use it: Build a completely custom single-product template and place your size guide where it most influences conversions.
Steps:
1. Install and activate SeedProd and enter your license key.
2. In SeedProd » Website Builder add a new Single Product template and set Conditions (all products or specific categories by slug).
3. In the editor arrange WooCommerce blocks (Product Image, Title, Price, Add to Cart, etc.).
4. Add your size guide using one of these options:
– Image block: upload a chart graphic and place it near the price or description.
– Product Data Tabs block: create a Size Guide tab and paste a measurement table and instructions.
– Accordion block: add a collapsible “Check Your Size” section to keep the layout compact.
5. Save and publish the template. Enable the SeedProd theme and ensure Header and Footer templates are set so navigation stays consistent.

Tips: Prefer responsive tables or tabbed content over static images for mobile users. Consider adding a small icon or call-to-action next to size selectors that opens the guide.

Bonus optimization ideas
– Track conversions and product performance with MonsterInsights or Google Analytics to see if size guides change behavior.
– Use social proof (for example, TrustPulse) to boost confidence and conversions.
– Reduce friction at checkout with a slide-out cart or streamlined checkout (plugins like FunnelKit can help).

FAQs

3. Will a size chart plugin slow my site? Good plugins only load scripts when needed; choose well-coded plugins and test performance.

7. How do size charts reduce returns? Clear measurements help customers choose correctly, reducing returns caused by fit issues.
8. How do I add selectable sizes and filters? Use WooCommerce product attributes and variations for selectable sizes. Use a product filter plugin (for example, WPFilters by SearchWP or similar) to let shoppers filter by size across the catalog.

Uncertain sizing costs sales and creates returns. Adding clear, mobile-friendly size charts removes doubt, increases conversions, and reduces support requests. Below is a concise guide to adding size charts in WooCommerce using three reliable approaches: a free plugin, a premium plugin, and a page builder.

– Page builder: SeedProd (Elite) — full control over custom product pages.

Why add a size chart?
– Fewer returns: customers pick the right size the first time.
– Higher conversions: shoppers feel confident buying.
– Less support: fewer measurement questions for your team.
– Better mobile UX: responsive tables or popups prevent scrolling frustration.
– SEO benefit: detailed product info can help search visibility.

Which approach should you choose?
– Tight budget/simple catalog: use the free WPC plugin.
– Growing store/large catalog: use Advanced Product Size Charts Pro for bulk assignment and templates.
– Full design control or custom UX: build product templates with SeedProd and embed your own size guides.

Method 1 — Free plugin: WPC Product Size Chart
1. Install and activate WPC Product Size Chart from WordPress.org.
2. Go to Size Charts » Add New and give the chart a clear title (for example, ‘Women’s Shoe Sizing’).
3. In Configuration, either upload a sizing image via Add Media or build a responsive table in Chart Table. Responsive tables are better for mobile.
4. Use the Apply dropdown to choose where the chart appears. Assign to categories for automatic display, or choose None to assign per product in the new Size Charts tab inside Product Data.
5. Publish. The plugin adds a Size Chart button that opens a popup for customers.

Notes: keep tables clean and remove empty rows so the live chart looks tidy. Provide both cm and inches when relevant.

Method 2 — Premium plugin: Advanced Product Size Charts Pro
1. Purchase, install, and activate the Pro plugin.
2. Go to Size Chart » All Size Charts and pick a pre-made template (for example, ‘Men’s T-Shirt’).
3. Edit the Chart Table: double-click cells to change values, add rows/columns with (+), and delete empty rows to avoid gaps.
4. In Size Chart Settings, select Modal Popup for a polished popup experience and customize button text, icon, and size.
5. Assign charts using meta boxes: Assign Category, Assign Tag, Assign Product. Checking a category applies that chart to every product inside it.
6. Publish or update and verify the popup and table on desktop and mobile.

Benefits: templates and bulk assignment save time for large catalogs. The Pro plugin also offers more design and display options.

Method 3 — Page builder: SeedProd (best for fully custom product pages)
1. Install and activate SeedProd. An Elite license is required for WooCommerce blocks.
2. In SeedProd » Website Builder add a new template and choose Type ‘Single Product’.
3. Set template conditions to include all products or specific categories (enter category names or slugs).
4. Use the drag-and-drop editor to lay out product elements: Product Image, Title, Price, Add to Cart, etc.
5. Add your size guide using one or more of these options:
– Image block: upload a sizing graphic.
– Product Data Tabs block: add a ‘Size Guide’ tab and paste a table or instructions.
– Accordion block: include a collapsible ‘Check Your Size’ or ‘How to Measure’ section.
6. Save and publish the template. Enable the SeedProd theme switch to apply your custom templates sitewide, but first build header and footer templates in SeedProd so navigation isn’t lost.

Important: enabling SeedProd replaces your active theme. Create header/footer templates in SeedProd before switching on the theme.
