What Are OG Images?

Open Graph (OG) images are the preview images that appear when links are shared on social media platforms like Facebook, Twitter, LinkedIn, Slack, and others. They were originally developed by Facebook as part of the Open Graph protocol but have since been widely adopted across the internet.

These images serve as visual representations of your content and play a crucial role in:

  • Making shared links more visually appealing
  • Increasing click-through rates from social platforms
  • Enhancing brand recognition across the web
  • Providing context about the content being shared
  • Improving overall engagement with your shared content

Platform-Specific OG Image Requirements

  • Minimum size: 600 x 315 pixels
  • Aspect ratio: 1.91:1
  • File format: JPG or PNG

Facebook displays larger preview images for sizes 1200 x 630 or larger, and smaller thumbnails for images below the minimum size.

  • Minimum size: 800 x 418 pixels
  • Aspect ratio: 16:9
  • File format: JPG, PNG, or GIF

Twitter uses Twitter Cards for rich media experiences. For optimal display, ensure your images maintain the 16:9 aspect ratio.

  • Recommended size: 1200 x 627 pixels
  • Minimum size: 600 x 315 pixels
  • Aspect ratio: Close to 1.91:1

LinkedIn closely follows Facebook's specifications, with a slight variation in the preferred height.

  • Slack: 600 x 300 pixels (2:1 ratio)
  • WhatsApp: 300 x 300 pixels (1:1 ratio)

Different platforms may display your OG images in various ways. Creating a standard image that works well across platforms is recommended.

OG Image Design Best Practices

Visual Elements

  • High contrast: Ensure text is easily readable against the background
  • Simple composition: Don't overcrowd the image; keep it clean and focused
  • Brand consistency: Include your logo or brand elements for recognition
  • High quality: Use sharp, non-pixelated images and graphics
  • Relevant imagery: Choose visuals that represent your content accurately

Text Content

  • Keep text minimal: 1-2 short lines works best
  • Large, legible fonts: Ensure readability even when scaled down
  • Consider mobile viewers: Text should be readable on small screens
  • 5-7 word rule: Aim for headlines that can be quickly scanned
  • Safe zones: Keep important text away from edges that might get cropped

Technical Optimization

  • File size: Optimize images to load quickly (under 200KB is ideal)
  • File format: Use JPG for photographs, PNG for graphics with text
  • Compression: Use modern compression techniques that maintain quality
  • Color mode: Use RGB color mode (not CMYK)
  • Test across platforms: Verify how your image appears on different networks

Implementing OG Images Correctly

To ensure your OG images appear correctly when your content is shared, you need to add specific meta tags to the <head> section of your webpage:

<meta property="og:image" content="https://yourwebsite.com/path-to-image.jpg" />
<meta property="og:image:width" content="1200" />
<meta property="og:image:height" content="630" />
<meta property="og:image:alt" content="Description of your image" />
<meta property="og:title" content="Your Page Title" />
<meta property="og:description" content="Brief description of your content" />
<meta property="og:url" content="https://yourwebsite.com/your-page" />

For Twitter Cards specifically, add these additional tags:

<meta name="twitter:card" content="summary_large_image" />
<meta name="twitter:image" content="https://yourwebsite.com/path-to-image.jpg" />

Pro Tip

Use Facebook's Sharing Debugger or Twitter's Card Validator to test how your OG images appear before sharing them publicly.

Measuring OG Image Performance

Track these metrics to understand how your OG images are performing:

  • Click-through rate (CTR): The percentage of people who click on your link after seeing it
  • Engagement rate: Likes, comments, and shares your content receives when shared
  • Bounce rate: How quickly people leave after clicking through (indicates if the image accurately represents the content)
  • Social media reach: How many people see your content when it's shared
  • A/B testing results: Compare different OG image designs to see which performs better

Regularly analyze these metrics and refine your OG image strategy based on the data to continuously improve performance.
