🧩 How to Use Metafields in Shopify: Customize Your Store Like a Pro

Shopify is a powerful platform, but sometimes you need more than what the default settings offer. That’s where Metafields come in — your secret weapon for customizing your store’s content, functionality, and design without the need for bulky third-party apps.

Whether you want to display extra product details, add custom fields for collections, or show personalized content on pages, Metafields let you go beyond the basics — and with Shopify’s native support, they’re easier to use than ever.

🔍 What Are Metafields?

Metafields are custom data fields that you can add to almost anything in Shopify — products, collections, orders, customers, and more. Think of them as extra storage for specific information that Shopify doesn’t provide out of the box.

Example Use Cases:

  • Product ingredients

  • Size guides per collection

  • Custom delivery messages per product

  • FAQ sections on pages

  • Technical specifications

🛠️ How to Create Metafields in Shopify (No Code)

Shopify’s admin now offers a visual metafield editor, making it simple to add and manage metafields.

🔹 Step 1: Go to the Metafields Section

  1. In your Shopify admin, go to Settings → Custom data.

  2. Select the type of resource you want to add a metafield to (e.g., Products, Collections, Orders).

🔹 Step 2: Add a New Definition

  1. Click “Add definition”.

  2. Enter a name, choose the namespace and key (like custom.size_guide), and set the content type (text, file, URL, boolean, etc.).

  3. Click Save.

🔹 Step 3: Add Metafield Values

Once you’ve created the definition:

  • Go to a product (or the relevant resource).

  • Scroll to the Metafields section at the bottom.

  • Add or update your value.

💻 How to Display Metafields in Your Theme (Code Method)

If you're using custom themes or Online Store 2.0, it’s easy to display metafields directly in Liquid:

🔸 Example: Show Product Metafield

l{{ product.metafields.custom.size_guide }} 

Replace custom with your namespace and size_guide with your key.

🔸 Render in Templates

You can place this code in:

  • product.liquid or main-product.liquid

  • collection.liquid, etc.

  • Or dynamically using Sections > Product information

🎯 Bonus: Use Metafields in Theme Editor (Online Store 2.0+)

If your theme supports Online Store 2.0:

  1. Open Customize in your theme.

  2. Navigate to a product or collection template.

  3. Add a block that supports dynamic sources.

  4. Click "Connect dynamic source" and choose your metafield.

✅ No coding needed — perfect for non-developers!

🚀 Pro Tips

  • Use namespaces like custom, details, or extra to organize metafields.

  • Stick to consistent naming for easier access and debugging.

  • Use list-type metafields for features like product highlights or bullet points.

🧠 When to Use Metafields vs Tags or Variants?

Feature Use Case
Metafields Structured custom data (ingredients, specs)
Tags Filtering and search
Variants When customers choose options (size, color)

🔐 Are Metafields Safe?

Absolutely. They’re:

  • Fully supported by Shopify

  • Stored securely

  • Editable from both admin and code

And unlike third-party workarounds, they won't break during updates.

🌟 Final Thoughts: Unlock Shopify’s Full Power

Metafields give you the flexibility to tell your product’s full story, improve user experience, and boost SEO — all without relying on third-party apps.

Whether you're a developer or a store owner with no coding background, metafields are a game-changing feature that lets you scale, personalize, and streamline your store like a pro.
