Blog featured image size guide
Recommended dimensions and aspect-ratio rules for article featured images that need to work on-page and across social previews.
Featured image pages work when they bridge editorial design and platform constraints. The right answer is not just a number; it is the relationship between the on-page crop and the social crop.
Good baseline
1600 × 900 px for on-page use
Social companion
1200 × 630 px when needed
Watch closely
Consistency across archive and detail views
Recommendation
Use a consistent on-page aspect ratio for the publication, with 1600 × 900 as a practical editorial baseline. Export a separate social card when the Open Graph crop differs materially.
Editorial workflow guidance
- Keep one consistent aspect ratio across archive cards and article headers.
- Do not let each article invent its own crop unless the design system supports it.
- Generate social-preview images separately when the platform ratio demands it.
Why it deserves a dedicated page
This query is not identical to Open Graph image size. Featured images are publication-system assets first and social assets second.
Checklist
- Pick one primary aspect ratio for featured images.
- Use a 1600 × 900 editorial baseline unless the design system says otherwise.
- Create separate social exports when required.
- Verify archive and detail-page crops together.
Common mistakes
- Using social-card dimensions as the only featured-image asset.
- Allowing inconsistent crops across the publication.
- Ignoring how the featured image appears in archive listings.
