OG Image Best Practices for Web Agencies

Correct Dimensions Per Platform

  • Open Graph / Facebook — 1200 x 630 px (1.91:1 ratio).
  • Twitter / X — 1200 x 628 px for summary_large_image cards.
  • LinkedIn — 1200 x 627 px for link posts.

Design Rules

  • Minimum font size 48px at full resolution. Below that, text becomes unreadable at thumbnail size.
  • High contrast between text and background. A 4.5:1 contrast ratio is the WCAG AA standard.
  • Logo in a consistent position. Top-left or bottom-left are conventional.
