# Shopify Metafields: Custom Fields Guide

Canonical: https://awsmcollections.com/glossary/what-are-shopify-custom-fields-and-how-to-utilize-them

**Metafields** (also called custom fields) let you store and display additional information in your Shopify store. If Shopify's standard fields don't capture everything you need—like product specifications, care instructions, or custom attributes—metafields fill the gap. This guide covers how to create and use them.

## What Are Metafields?

Metafields are custom data fields you can add to various Shopify resources:

- **Products:** Specifications, materials, care instructions
- **Variants:** Per-variant details like color codes or sizing charts
- **Collections:** Additional descriptions, featured banners
- **Customers:** Preferences, account notes
- **Orders:** Special instructions, internal notes
- **Pages and blogs:** Custom content sections

## Creating Metafield Definitions

### Step 1: Access Custom Data

1. Go to **Settings** in your Shopify admin
2. Click **Custom data** (or **Metafields** in older versions)
3. Select the resource type (Products, Collections, etc.)

### Step 2: Add a Definition

1. Click **Add definition**
2. Enter a name (what you'll see in admin)
3. Choose the data type
4. Add a description (optional but helpful)
5. Set validation rules if needed
6. Save

## Metafield Data Types

### Text

- **Single line text:** Short text like brand names, materials
- **Multi-line text:** Longer content like care instructions
- **Rich text:** Formatted content with headings, lists, links

### Numbers

- **Integer:** Whole numbers
- **Decimal:** Numbers with decimal places
- **Rating:** Star ratings (1-5 scale)

### Measurements

- **Dimension:** Length, width, height
- **Weight:** Product weights
- **Volume:** Capacity measurements

### References

- **Product:** Link to another product
- **Variant:** Link to a specific variant
- **Page:** Link to a store page
- **File:** PDFs, images, documents

### Other Types

- **URL:** Web addresses
- **Color:** Color picker with hex values
- **Date:** Date values
- **True or false:** Boolean toggles
- **JSON:** Structured data

## Adding Metafield Values

Once definitions are created, add values to individual items:

1. Edit a product (or collection, customer, etc.)
2. Scroll to the **Metafields** section
3. Enter values for your defined fields
4. Save

## Displaying Metafields on Your Store

### Theme Customizer (Recommended)

Modern themes (Online Store 2.0) support metafields natively:

1. Open the theme customizer
2. Navigate to the template (product page, collection page, etc.)
3. Add a section or block that supports dynamic content
4. Click **Connect dynamic source**
5. Select your metafield

### Liquid Code

For advanced customization, access metafields in Liquid templates:

### Collection Enhancements

Add metafields to [collections](https://awsmcollections.com/glossary/what-is-a-shopify-collection-and-how-does-it-work) for:

- Featured banners or promotional images
- Extended descriptions
- Category-specific content

**Enhance Your Collections:** [AWSM Collections](https://awsmcollections.com/) works alongside metafields to create dynamic, well-organized collections that showcase your products effectively.

## Metafield Best Practices

- **Use clear naming:** Names should be immediately understandable
- **Add descriptions:** Help staff understand what to enter
- **Choose the right type:** Use specific types (numbers, dates) rather than text when possible
- **Set validation:** Add min/max values or required fields where appropriate
- **Plan before creating:** Document your metafield structure before building

## Managing Metafields at Scale

- **Bulk editor:** Edit metafields across multiple products
- **CSV import:** Import metafield values via spreadsheet
- **Apps:** Third-party apps provide advanced metafield management
- **API:** Developers can manage metafields programmatically

## Conclusion

Metafields extend Shopify's flexibility, letting you store and display exactly the information your business needs. Start with a few key definitions for your most important custom data, then expand as you identify more use cases. Well-organized metafields improve both your admin experience and customer-facing content.
