If you run an online store that sells clothing, shoes, or accessories, you already know the struggle. Customers buy the wrong size. They return items. They leave bad reviews. And worst of all, they don’t come back.
Size charts fix this. They give shoppers the confidence to buy the right size the first time. And in WooCommerce, adding size charts is easier than you think.
This guide walks you through everything, from why size charts matter to the exact steps to add them to your store in 2026.
WooCommerce does not include a built-in size chart feature. Store owners add size charts using dedicated plugins such as YITH WooCommerce Size Charts or Size Chart for WooCommerce, which allow charts to display as a popup, tab, or inline section on product pages.
Charts can be assigned to individual products or entire categories. Manual methods using HTML tables or custom product tabs are also available for those who prefer a code-based approach.
Why Size Charts in WooCommerce Are Important?
Size charts are not just a nice-to-have feature. They directly affect your store’s revenue. When shoppers can’t figure out what size to buy, they either guess (and return the item) or they leave your site entirely.
According to industry data, sizing issues are one of the top reasons for returns in online fashion retail. Adding a size chart reduces this friction and builds customer trust.
How Size Charts Improve Customer Shopping Experience?
A good size chart removes one of the biggest barriers in online shopping, the fear of ordering the wrong size.
When customers can compare their measurements to a chart, they feel more confident placing the order. This leads to fewer cart abandonments, lower return rates, and higher customer satisfaction. It’s one of the easiest ways to improve your store’s user experience without redesigning anything.
You don’t need a fancy design overhaul to see results. A simple, clear size chart does the job. Think about how much smoother the shopping experience becomes when someone can measure themselves at home and match those numbers to their chart before clicking “Add to Cart.”
Benefits of Adding Size Charts in WooCommerce Stores
Here’s what you gain when you add size charts to your WooCommerce store:
Fewer returns: When customers pick the right size upfront, your return volume drops. This saves you money on shipping and restocking.
Higher conversion rates: Shoppers who feel confident about sizing are more likely to complete a purchase.
Better reviews: Satisfied customers who received the right size leave positive feedback, which builds social proof.
Reduced support queries: Fewer “what size should I order?” emails or chat messages free up your team’s time.
The combination of these benefits directly impacts your bottom line. For WooCommerce stores focused on Google Shopping feed optimization, accurate product data, including sizing, also helps product listings perform better.
Which WooCommerce Stores Need Product Size Charts?
Not every product needs a size chart. But if your store sells any of the following, you definitely do:
- Clothing: T-shirts, dresses, jackets, pants, and activewear all vary widely by brand and country.
- Footwear: Shoe sizes differ between the US, UK, and EU standards. A size chart makes this clear.
- Accessories: Belts, hats, gloves, and rings all depend on measurements.
- Kids’ clothing: Parents need to match their child’s age, height, and weight to the right size.
- Sports equipment: Helmets, gloves, and protective gear often come in size-specific options.
If your store sells any of these product types, adding a size chart is non-negotiable.

Different Ways to Add Size Charts in WooCommerce
WooCommerce doesn’t include a built-in size chart feature. But there are several ways to add one:
- Using a dedicated plugin: The fastest and most flexible option. Plugins give you prebuilt templates, pop-up support, and mobile-ready layouts.
- Custom HTML/CSS shortcodes: A manual approach where you create a table using HTML and insert it into product descriptions or custom tabs.
- Page builders: Tools like Elementor or Divi let you visually design a size chart and embed it on your product pages.
- Custom code: Developers can create a custom WooCommerce tab using PHP and add a size chart directly to the product page template.
For most store owners, using a plugin is the smartest choice. It saves time, requires no coding, and gives you professional results right out of the box.
How to Add Size Charts in WooCommerce Using a Plugin (Step by Step)
Let’s walk through the full process of adding a size chart using a plugin. This method works for any WooCommerce store, regardless of your theme or page builder.
Step 1: Choose the Right WooCommerce Size Chart Plugin
Start by picking the right plugin. Look for one that offers:
Multiple chart templates, easy drag-and-drop table editing, category and product-level assignment, and responsive design for mobile users.
Popular options include YITH WooCommerce Size Charts, WooCommerce Size Chart Plugin by PluginHive, and Size Chart for WooCommerce by WP Moose. All of these offer free or freemium tiers to get started.
Step 2: Install and Activate the Size Chart Plugin
Go to your WordPress dashboard. Navigate to Plugins → Add New. Search for your chosen plugin by name.
Click Install Now, then Activate. The plugin will appear in your WooCommerce or WordPress admin menu once it’s active.
Make sure you’re using a well-maintained plugin. Check the last update date and user reviews before installing. A poorly maintained plugin can cause compatibility issues with your store, especially after WordPress or WooCommerce updates.
If you’re ever concerned about site health, a WordPress maintenance agency can help keep everything running smoothly.
Step 3: Create a New Product Size Chart
After activation, find the plugin’s menu in your WordPress dashboard. Click Add New Size Chart or the equivalent option in your plugin.
Give your chart a clear name, for example, “Women’s Apparel Size Chart” or “Men’s Footwear Chart.” This makes it easier to manage when you have multiple charts for different product categories.
Step 4: Add Size Measurements and Product Dimensions
Now, build out your size chart content. This is the most important step; accuracy matters here.
Add columns for each size (XS, S, M, L, XL, XXL) and rows for measurements like chest, waist, hips, and length. Include both inches and centimeters to serve international shoppers.
Use your actual product measurements, not just generic brand standards. If your supplier provides measurement specs, use those directly. Inaccurate charts are worse than no chart at all.
Step 5: Customize the Design and Layout of the Size Chart
Most plugins let you customize colors, fonts, borders, and column widths. Match your chart’s styling to your store’s branding.
Use clear headers. Make sure the chart is easy to scan at a glance. Avoid cluttered layouts. For more complex design decisions, a solid wireframe guide can help you plan the layout before building.
Keep the chart simple. Shoppers should be able to find their size in under 10 seconds.
Step 6: Assign Size Charts to Specific Products or Categories
Assign the chart to the right products. Most plugins let you assign by individual product or by category.
For example, assign your “Men’s T-Shirt Chart” to all products in the Men’s Clothing category. This saves time — you don’t have to manually assign the chart to each product.
If different products have different size guides (e.g., tops vs. bottoms), create separate charts and assign them accordingly.
Step 7: Configure Popup, Tab, or Inline Display Settings
Decide how the size chart will appear on product pages. You have three main options:
- Popup: The chart opens in a lightbox when a shopper clicks a link such as “Size Guide.” This keeps the product page clean.
- Tab: The chart appears as a new tab alongside the Description and Reviews tabs on the product page.
- Inline: The chart is embedded directly within the product description.
Popup and tab displays are the most popular. They’re clean, non-intrusive, and accessible. Configure the trigger button text (e.g., “View Size Chart” or “Find Your Size”) and position it near the size selector for maximum visibility.
Step 8: Preview the Size Chart on Product Pages
Before publishing, preview the size chart. Most plugins have a built-in preview mode.
Check that the measurements are accurate, the design looks clean, and the chart displays correctly on the product page. Pay special attention to the trigger button placement — it should be easy to spot near the size options.
Step 9: Test the Size Chart Across Desktop and Mobile Devices
Mobile testing is critical. Most online shoppers browse on smartphones. If your size chart doesn’t render properly on mobile, you’re losing conversions.
Test the chart on both Android and iOS. Check that tables don’t overflow the screen width. Make sure popups are scrollable on smaller screens.
If you’re unsure about the difference between a mobile site and a responsive site, this can affect how your size charts display across devices.
If the chart breaks on mobile, adjust the column widths or enable a horizontal scroll for the table.
Step 10: Publish and Monitor Customer Engagement
Once everything looks good, publish the size chart. Your shoppers will now see it live on your product pages.
Monitor performance after launch. Track your return rates, conversion rates, and bounce rates over the following weeks. If returns decrease and conversions improve, your size chart is working.
You can also check heatmaps or click tracking (via tools like Hotjar) to see if shoppers are actually clicking the size chart link. If they’re not, consider adjusting the button placement or copy.
Best WooCommerce Size Chart Plugins for 2026
Here’s a quick overview of the top size chart plugins available this year:
- YITH WooCommerce Size Charts: One of the most feature-rich options. Supports multiple charts per product, pop-up display, and custom table design. Both free and premium versions are available.
- Size Chart for WooCommerce by WP Moose: A lightweight, easy-to-use plugin with template support and category-level assignment. Great for beginners.
- WooCommerce Size Chart Plugin by PluginHive: Supports drag-and-drop table editing, multiple display styles, and unit conversion between inches and centimeters.
Choose a plugin based on your store size, budget, and technical comfort level. Always check compatibility with your current WooCommerce version before installing.
For stores concerned about HIPAA compliance for ecommerce, also verify the plugin doesn’t collect or expose sensitive user data.
How to Create Custom Size Charts in WooCommerce Without a Plugin?
If you’d rather not use a plugin, you can add a size chart manually. Here’s how:
- Option 1: Add to Product Description: Create an HTML table directly in the product description. Use the Text/HTML editor in WordPress to insert a table with your size data. This is the simplest method, but it offers no advanced display options.
- Option 2: Create a Custom Product Tab: Use a free plugin like “WooCommerce Tab Manager” or add a custom tab via code. Place your size chart HTML inside the custom tab. This keeps your product description clean.
- Option 3: Use a Page Builder: If you use full site editing in WordPress, you can design a reusable size chart block and embed it on product pages. This works well for stores with consistent sizing across product lines.
- Option 4: Custom PHP Template: Developers can add a WooCommerce hook (e.g., woocommerce_single_product_summary) to programmatically inject a size chart into the product page template. This requires coding knowledge but gives you full control.
The manual approach takes more effort but offers greater flexibility. It’s ideal for developers or store owners with technical experience.
WooCommerce Size Chart Design Best Practices
A size chart is only useful if shoppers can actually read and understand it. Follow these design principles:
- Keep it concise: Don’t overload the chart with unnecessary columns. Focus on the measurements that matter most for your product type.
- Use clear labels: Label each row and column clearly. Avoid abbreviations that shoppers might not recognize.
- Provide both unit systems: Always include both metric (cm) and imperial (inches) measurements. This serves international customers and reduces confusion.
- Make it mobile-friendly: Use responsive table layouts. On mobile, consider a vertically stacked layout instead of a wide horizontal table.
- Place the chart close to the size selector: The size chart link or button should appear immediately next to or below the size selection dropdown. This is where shoppers are actively thinking about sizing.
- Add a how-to-measure guide: A short paragraph or illustration showing how to take measurements (chest, waist, inseam, etc.) dramatically improves chart usability.
- Update regularly: If your supplier changes sizing or you add new product lines, update your charts to reflect those changes. Outdated charts cause the same problems as no chart at all.
These best practices apply whether you’re building for a fashion brand, a sporting goods store, or a kids’ clothing shop.
Good content strategy, including how you structure your meta descriptions and product pages works hand in hand with strong on-page elements, such as size charts, to improve overall SEO and conversion performance.
