OG Image Guide: Triple Your Blog Click Rate

The big image shown when you share a link on Slack, Facebook, X. Design quality of this OG image can swing CTR by 2–3Γ—. How to ship one in 1 minute.

⏱ What you'll learn
  • What OG images are and why they matter
  • The 1200Γ—630 universal standard
  • 1-minute PXLTool workflow

πŸ“Œ What is an OG image?

Open Graph (OG) is a Facebook-created standard from 2010 that defines preview-card information (title, description, image) when URLs are shared. Today, virtually every platform: Slack, Discord, X, LinkedIn, even WhatsApp: follows it.

If your OG image isn't compelling? Even great articles don't get clicked. Global data: posts with OG images get 38% higher CTR than without; well-designed OG images double that.

πŸ“ Size standard

1200Γ—630 (1.91:1) is the universal standard. This ratio renders perfectly on Facebook, Slack, X, Discord, LinkedIn: anywhere.

  • Minimum: 600Γ—315 (blurry on mobile)
  • Recommended: 1200Γ—630 (universal)
  • Maximum: 2400Γ—1260 (retina, < 8 MB)

🎨 3 design principles

Principle 1 Β· Title fills 50%

On mobile, OG images render 100–200 px wide. For readability at that size, title text must occupy 50%+ of the image. Photo + tiny caption combos = invisible.

Principle 2 Β· Brand consistency

Use the same font, colors, logo position across every OG image. Frequent sharers will recognize "ah, this blog again" instantly. That's branding.

Principle 3 Β· Legibility over beauty

Beauty is nothing without readability. 4.5:1 contrast ratio per WCAG. White-on-yellow = never. Dark background + bright text = safest.

πŸ›  1-minute workflow

Method A Β· LinkedIn post tool

The LinkedIn Post Image tool outputs 1200Γ—627: works as an OG image directly. Type title, subtitle, author, company, download PNG. 30 seconds.

Method B Β· Email header banner

The Email Header tool has a 1200Γ—300 wide option. Good for more compact OG images.

Method C Β· Gradient blur background + text

For premium Apple / Vercel vibes: use the Gradient Blur tool for the background and the Gradient Text tool for the title. Composite in Canva's free tier.

πŸ”§ HTML meta tags

Once you have the image, add this to your HTML <head>:

<meta property="og:title" content="Post title">
<meta property="og:description" content="Description, max 160 chars">
<meta property="og:image" content="https://yoursite.com/og.png">
<meta property="og:url" content="https://yoursite.com/post">
<meta property="og:type" content="article">

<!-- Twitter Cards (X) -->
<meta name="twitter:card" content="summary_large_image">
<meta name="twitter:title" content="Post title">
<meta name="twitter:image" content="https://yoursite.com/og.png">

πŸ’‘ Pro tip: after editing, refresh cache at developers.facebook.com/tools/debug. X / Discord update automatically but can take hours.

🎯 Platform variations

  • Facebook: 1200Γ—630 recommended
  • X (Twitter): 1200Γ—675 (1.78:1) preferred
  • LinkedIn: 1200Γ—627
