  • 40px minimum padding from all edges
  • Some platforms crop edges or add rounded corners

Colors

Background TypeWhen to Use
Solid brand colorConsistent series, corporate
GradientModern, eye-catching
Photo with overlayBlog posts, editorial
Dark backgroundBetter contrast, stands out in feeds

Dark backgrounds outperform light in social feeds — most feeds have white/light backgrounds, so dark OG images pop.

Templates by Content Type

Blog Post

infsh app run infsh/html-to-image --input '{
  "html": "Engineering BlogHow We Reduced Build Times by 80%A deep dive into our CI/CD optimization"
}'

Product/Launch Announcement

infsh app run infsh/html-to-image --input '{
  "html": "Now AvailableDataFlow 2.0Automated reports. Zero configuration."
}'

Tutorial/How-To

infsh app run infsh/html-to-image --input '{
  "html": "TUTORIALBuild a REST API in 10 Minutes with Node.jsStep-by-step guide with code examples"
}'

AI-Generated Visual OG

# When you want a striking visual instead of text-based
infsh app run falai/flux-dev-lora --input '{
  "prompt": "clean professional social sharing card, dark gradient background, abstract geometric shapes, modern tech aesthetic, minimal, no text, 1200x630 equivalent aspect ratio",
  "width": 1200,
  "height": 630
}'

OG Meta Tags Reference

<!-- Essential (Facebook, LinkedIn, Discord, Slack) -->


<!-- Twitter/X specific -->


<!-- Image dimensions (optional but recommended) -->


Twitter Card Types

Card TypeImage SizeUse When
summary800 x 418 (small thumbnail)Short updates, links
summary_large_image1200 x 628 (full width)Blog posts, articles, announcements

Always use summary_large_image unless you have a specific reason not to — the large image gets significantly more clicks.

Consistency System

For a blog or site with many pages, create a template system:

ElementKeep ConsistentVary
Background styleSame gradient or brand colors—
Font familySame font—
LayoutSame positioning—
Logo/brandingSame placement (corner)—
Category badgeSame styleColor per category
Title textSame size/weightContent changes
