How Your Facebook Post Will Look
This preview tool shows you the exact layout Facebook uses for posts in the news feed. When you upload an image and add your post text, you see a realistic Facebook card with your page name, avatar placeholder, timestamp, post text, image (cropped to 1.91:1 like Facebook does), and the like/comment/share action bar.
Below the preview, you get detailed image information — your image's actual dimensions, its aspect ratio compared to Facebook's recommended 1.91:1, and a clear indicator of whether Facebook will crop your image. This helps page admins and social media managers catch problems before they go live.
If your image is not 1200×630, the preview shows you exactly how the cropped version will look — so you can decide whether to resize before posting.
Why Preview Before Posting?
Publishing a Facebook post without previewing it first is how broken images, awkward cropping, and cut-off text end up on your page. Here is what goes wrong without a preview:
Your image gets cropped and the main subject is cut off
Text overlaid on the image becomes unreadable after cropping
The post looks unprofessional to your audience
Link previews show the wrong image or a broken thumbnail
You waste time deleting and re-posting to fix the problem
A quick preview check takes seconds and saves you from posting content that hurts your brand. Social media managers running multiple pages especially benefit — previewing every post before it goes live ensures consistent quality across all accounts.
Facebook Post Image Best Practices
Size: Use 1200×630 pixels for optimal display in the news feed
Aspect ratio: 1.91:1 avoids all cropping on both desktop and mobile
Text overlay: Keep text to less than 20% of the image area — Facebook may reduce reach for text-heavy images
Contrast: Use high contrast between your subject and background so the image stands out in a busy feed
Format: JPG for photographs, PNG for graphics with text or sharp edges
File size: Keep images under 8MB — smaller files load faster especially on mobile
Safe zone: Keep important content away from edges since Facebook may crop slightly differently across devices
For link post previews (when sharing a URL), the OG image is even more important. Facebook pulls the og:image meta tag from your page. If that image is missing, too small, or the wrong aspect ratio, your link preview will look broken.
Common Facebook Post Preview Issues
If you have ever asked "why does my Facebook post look wrong?" — here are the most common causes and what to do about them:
Link preview not showing an image
Your page is missing the og:image meta tag, or the image URL is broken. Use the link preview debugger to validate your OG tags, or the thumbnail analyzer to check your OG image quality.
Wrong image showing in link preview
Facebook caches OG data aggressively. If you updated your image after the link was first shared, Facebook is still using the old version. Use the Facebook Sharing Debugger to force a re-scrape of your URL.
Image cropped awkwardly
Your image is not at the 1.91:1 aspect ratio. Facebook crops from the center, so tall or overly wide images lose content on the edges. Use the image size checker to verify dimensions, then resize to 1200×630 before uploading.
Image appears small or as a tiny thumbnail
Images smaller than 600×315 pixels display as small side-thumbnails instead of full-width cards. Always use images at least 1200×630 for the large, attention-grabbing card format.
How to Fix Facebook Link Preview
If your link preview is showing the wrong image, title, or description, follow these steps:
Check your Open Graph tags — Make sure your page includes og:title, og:description, and og:image meta tags in the <head>
Verify the image URL — The og:image URL must be absolute (start with https://), publicly accessible, and point to a valid image file
Use the correct image size — The OG image should be at least 1200×630 pixels. Smaller images may show as tiny thumbnails or not appear at all
Clear Facebook's cache — Go to the Facebook Sharing Debugger, paste your URL, and click "Scrape Again" to force Facebook to re-read your page's metadata
Wait and re-test — After scraping, paste your link into a new Facebook post to confirm the preview looks correct
For WordPress sites, OG tags are typically managed by plugins like Yoast SEO or Rank Math. Make sure the "Social" or "Facebook" image field is set for each page and post you share.
Frequently Asked Questions
How do I preview my Facebook post before publishing?▼
Upload your post image to this free Facebook post preview tool, enter your post text and page name, and instantly see how your post will appear in the Facebook news feed. The preview shows the full post card including image cropping, text layout, and engagement buttons — so you can catch any issues before publishing.
Why is my Facebook post preview showing the wrong image?▼
Facebook caches Open Graph metadata from your URL. If you changed the image after the link was first shared, Facebook still uses the old version. Go to the Facebook Sharing Debugger, paste your URL, and click "Scrape Again" to force Facebook to re-read your page. Also verify that your og:image tag points to a valid, publicly accessible image URL.
What size image should I use for a Facebook post?▼
The recommended image size for Facebook posts is 1200×630 pixels with a 1.91:1 aspect ratio. This size ensures your image displays as a full-width card without any cropping on both desktop and mobile. Images smaller than 600×315 may show as small thumbnails. Use the image size checker to verify your dimensions.
Why is Facebook cropping my post image?▼
Facebook crops images that do not match the 1.91:1 aspect ratio. If your image is taller (like a square or portrait), the top and bottom are cropped. If it is too wide, the sides are cropped. The cropping is centered. To avoid it, resize your image to exactly 1200×630 pixels before uploading. Use this preview tool to see exactly how the cropped version will look.
How do I fix my Facebook link preview?▼
First, make sure your page has correct Open Graph meta tags: og:title, og:description, and og:image. The image must be at least 1200×630 and publicly accessible. Then visit the Facebook Sharing Debugger and click "Scrape Again" to clear the cached preview.
