Thumbnail

Use thumbnails as a visual anchor and identifier for an object. They should be used along with text to provide context.

Use as the default size.

import {Thumbnail} from '@shopify/polaris';
import React from 'react';

function ThumbnailExample() {
  return (
    <Thumbnail
      source="https://burst.shopifycdn.com/photos/black-leather-choker-necklace_373x@2x.jpg"
      alt="Black choker necklace"
    />
  );
}

Best practices

On web, thumbnails should:

  • Be one of 4 sizes:
    • Extra small (24 x 24 px): use in tightly condensed layouts
    • Small (40 × 40 px): use when the medium size is too large for the layout, or when the thumbnail has less importance.
    • Medium (60 × 60 px): use as the default size.
    • Large (80 × 80 px): use when an thumbnail is a major focal point. Avoid this size in lists of like items.

On Android and iOS, thumbnails should:

  • Be one of 2 sizes:
    • Default (40 × 40): use as the default size.
    • Large (72 × 72): use when an thumbnail is a major focal point. Avoid this size in lists of like items.

Content guidelines

Any time you use an image to communicate a concept on Shopify, it’s important to use descriptive alt text. Doing this is important for accessibility because it allows screen readers to describe what’s in the image to people who may not be able to see it.

For thumbnails, we recommend using a format that describes what will show in the image:

  • On web, alt="Photo of {product}". For example, “Photo of black t-shirt with cartoon tiger”.
  • On web, an empty alt="" attribute ignores the image in assistive technologies such as screen readers, and may be used on decorative thumbnails.
  • On iOS, imageView.accessibilityLabel = "Photo of {product}". For example, “Photo of black t-shirt with cartoon tiger”.
  • On Android, android:contentDescription="Photo of {product}". For example, “Photo of black t-shirt with cartoon tiger”.
