What are Metafields in Shopify?

If you’ve ever felt limited by Shopify’s default product fields, Shopify metafields offer a powerful solution. But what exactly is a metafield in Shopify? Simply put, a metafield is a customizable data field that allows you to store and display specialized information across your store.

Unlike Shopify’s built-in fields, metafields enable you to add unique attributes that enhance both store functionality and the shopping experience.

How Do Shopify Metafields Work?

Shopify product metafields serve two key purposes:

• Internal tracking – Store hidden data for backend operations, such as product SKUs, supplier codes, or custom stock details.
• Customized information display – Show extra details on product pages, collections, or orders, such as size charts, material compositions, care instructions, or personalized recommendations.

Shopify Metafields in Action

Let’s say you sell handcrafted candles. Each candle has a unique burn time, but Shopify’s standard product pages don’t include a field for this. With metafields, you can easily add and display this critical information, ensuring customers make informed purchasing decisions.

Beyond product-specific details, Shopify metafields support various applications, including:

• Color swatches for product variations.
• Downloadable files (user manuals, guides, or templates).
• Custom expiration dates for perishable goods.
• Product ratings or special attributes like eco-friendly certifications.

Breaking Down Shopify Metafields

Each Shopify metafield consists of four key components:

1. Namespace & Key – This combination serves as a unique identifier for the metafield.
   • The namespace groups similar metafields together.
   • The key defines the specific metafield within that group.
   • Example: products.expiration_date and products.rating
   • Only letters, numbers, underscores (_), and hyphens (-) are allowed.
2. Value – This determines the data type and format stored in the metafield.
   • Supported formats include plain text, numbers, URLs, booleans, and JSON.
   • Example: A metafield for a shoe size might store an integer (size: 42).
3. Description (Optional) – A helpful note within the Shopify admin to guide input and ensure correct metafield usage.
4. Validation (Optional) – Set restrictions to limit acceptable values, preventing errors when entering metafield data.
   • Example: Ensuring an expiration date follows the YYYY-MM-DD format.

Where Can You Use Shopify Metafields?

Metafields aren’t just for products — they can be applied across different Shopify store elements, including:

• Collections – Add category-specific attributes (e.g., “Best Sellers” labels).
• Customers – Store loyalty tier levels or preferences.
• Orders – Track custom shipping instructions or gift messages.
• Pages & Blogs – Include dynamic metadata or SEO enhancements.

By leveraging Shopify metafields, you can create a more dynamic, personalized, and data-rich shopping experience, improving both customer engagement and backend efficiency.

Different Types of Shopify Metafields

Now, let’s look at the different types of Shopify metafields. Each type is suitable for specific situations, as they accept a range of supported values. Below is a table showcasing the most common Shopify metafield types, their supported values, and example use cases:

This table provides a comprehensive overview to help you choose the appropriate metafield type for your needs.

How to Add Metafields in Shopify

Adding Shopify product metafields involves three main steps:

1. Create a metafield in the Shopify admin.
2. Assign it to specific products.
3. Display the metafield content on product pages.

Let’s walk through each step in detail.

Step 1: Create a Shopify Metafield

Before you can add Shopify metafields to products, you need to define them in your admin settings. Here’s how:

1. Navigate to Settings → Custom Data → Metafields.
2. Select Products.
   
3. Click “Add definition”.
   

Next, configure your metafield:

• Metafield name – Example: Material.
• Namespace & key – A unique identifier (e.g., product.material).
• Description (Optional) – A brief note for internal use.
  
• Metafield type – Choose the appropriate data format (e.g., Single line text, Integer, URL, File, etc.).
  
• Validation rules – Set restrictions like character limits or preset choices to streamline product entry.

Pro Tip: If you frequently reuse certain values (e.g., materials like “Wood,” “Metal,” “Glass”), enable “Limit to preset choices” in the Validation section. This allows you to select values from a drop-down instead of manually entering them each time — saving effort and reducing errors.

Repeat these steps to create as many Shopify metafields as needed.

Step 2: Add Shopify Metafields to a Product

Once you’ve set up metafields, it’s time to apply them to products. Let’s say you’re selling chairs and want to include material and designer details on product pages. Here’s what to do:

1. Go to Admin → Products.
   
2. Select the product you want to edit.
   
3. Scroll down to the Metafields section.
4. Enter the relevant values (e.g., Material: Oak Wood, Designer: John Doe).
   
5. Repeat for all necessary metafields.
6. Click Save.

Bulk Editing Tip: If you’re updating multiple products at once, consider using Shopify’s bulk editor or a CSV import for faster metafield entry.

Step 3: Display Metafields on Product Pages

Now that Shopify metafields are assigned, you need to display them on the storefront. Follow these steps to make your custom product data visible to customers:

1. Go to Admin → Online Store → Themes → Customize.
   
2. Select Products → Default product template.
   .
3. Click Add Block under the Product section.
   
4. Select Dynamic Source (Metafield Content) from the settings panel.
5. Choose the relevant Shopify product metafield to display (e.g., “Material”).
   
6. Save and preview your product page.

Customization Tip: You can position metafields anywhere on the page — under the product title, in the description, or in a custom tab. If needed, use Shopify Liquid for advanced formatting.

As you can see, Shopify metafields empowers you to go beyond Shopify’s default product fields, creating rich, informative, and engaging product pages tailored to your store’s needs. Whether you’re adding product specifications, care instructions, size charts, or downloadable files, Shopify metafields give you the flexibility to enhance both user experience and store functionality.
