Facebook Feed Post Dimensions
Facebook supports several aspect ratios in the feed. The right one depends on what you're posting:
| Format | Dimensions | Use For |
|---|---|---|
| Square (1:1) | 1200 × 1200 px | Default — most mobile feed real estate |
| Portrait (4:5) | 1080 × 1350 px | Tallest format Facebook displays uncropped |
| Landscape (1.91:1) | 1200 × 630 px | Link previews, header-style images |
| Vertical (9:16) | 1080 × 1920 px | Crops to 4:5 in feed; full size only in Stories/Reels |
Square (1:1) and portrait (4:5) consistently outperform landscape on mobile because they take up more pixels and force a longer scroll past. Use them as the default for all organic posts.
Link Preview Size
When you paste a URL into Facebook, it renders the page's Open Graph image at 1200 × 630 pixels (1.91:1). Set this as og:image in your page meta:
<meta property="og:image" content="https://example.com/og.png" />
<meta property="og:image:width" content="1200" />
<meta property="og:image:height" content="630" />If Facebook caches an old image, force a refresh using the Facebook Sharing Debugger. Avoid placing important text smaller than 24 px in the OG image — Facebook scales it down significantly in mobile previews.
Image File Format
- JPG: Photos, gradients, scenery — smallest file, fastest load
- PNG: Graphics with text, logos, transparent overlays — sharpest edges
- GIF: Animated graphics only — Facebook's static GIF compression is poor
- WebP: Not yet recommended — Facebook may convert to JPG with quality loss
Always export in sRGB color mode. Adobe RGB and other profiles get crushed when Facebook converts to sRGB internally.

Multi-Image Post Behavior
Multi-image posts crop into a grid. Layout depends on image count:
- 2 images: side-by-side, both cropped to 1:1
- 3 images: one large left, two small right (1:1 + two stacked 1:1)
- 4 images: 2×2 grid, all 1:1
- 5+ images: 5 visible, "+N more" overlay on the last tile
Keep subjects centered. Anything in the corners gets cropped out of the grid view.
Tips for Better Facebook Feed Performance
- Upload at 1200 × 1200 (square) or 1080 × 1350 (portrait) for organic posts
- Reserve 1200 × 630 for link preview OG images
- Export in sRGB — never Adobe RGB
- Use PNG for any post with text; JPG for photos
- Add captions to video — most Facebook autoplay is muted
- Avoid GIF for static images — use JPG or PNG

Frequently Asked Questions
What is the Facebook post size?
The Facebook post image size depends on format: 1200 × 630 px for link previews (1.91:1), 1200 × 1200 px for square images (1:1), and 1080 × 1350 px for portrait images (4:5). Square and portrait take more screen space on mobile.
What is the size for a Facebook link preview?
The Facebook link preview size is 1200 × 630 pixels at a 1.91:1 aspect ratio. Set this as your og:image meta tag. Use the Facebook Sharing Debugger to refresh the preview if Facebook is showing an old cached image.
What aspect ratio should I use for a Facebook post?
For organic feed posts, use 1:1 (1200 × 1200) or 4:5 (1080 × 1350). Both take up more vertical space on mobile feeds than landscape, which boosts thumb-stop rate. Reserve 1.91:1 (1200 × 630) for link previews only.
What is the Facebook video post size?
Facebook supports videos up to 1080p in any aspect ratio: 1:1 square (1080 × 1080), 4:5 portrait (1080 × 1350), 16:9 landscape (1920 × 1080), or 9:16 vertical (1080 × 1920). Vertical videos cap out at 4:5 in the feed (taller gets cropped).
What is the maximum file size for a Facebook post?
Images are limited to 30 MB. Videos are limited to 10 GB and 240 minutes. For best quality, keep images under 5 MB and use H.264 video codec at 30 fps.
Why does my Facebook image look blurry?
Blurry posts usually come from uploading below 1200 px wide, using a non-sRGB color profile, or letting Facebook upscale a smaller image. Always export at the recommended dimensions in sRGB color mode and use PNG for images with text.
How does Facebook crop multi-image posts?
Facebook auto-crops multi-image posts to fit a grid. With 2 images, both crop to 1:1 side-by-side. With 3+, the layout shifts to a "1 large + grid" arrangement. Keep important subjects centered to survive the crop.
What size is the boosted post / Facebook ad?
Boosted posts use the same dimensions as organic posts (1200 × 1200, 1080 × 1350, or 1200 × 630). For dedicated ads, the recommended sizes are 1200 × 628 px for single image ads and 1080 × 1350 px for vertical mobile-first creative.
