OG Image Size Guide: The Complete Guide for 2026
One size fits almost every platform. Here's exactly what dimensions you need, why it works, and how to get it right in under a minute.
The Quick Answer: 1200 × 630 pixels
If you only remember one number, make it 1200 x 630 pixels (1.91:1 aspect ratio). This is the recommended size for Facebook, Twitter/X, LinkedIn, Discord, Slack, WhatsApp, and virtually every other platform that uses Open Graph metadata.
File size: keep it under 5MB. Format: JPG or PNG.Minimum: 600 x 315 (but quality suffers).
Why 1200 x 630?
Facebook originally defined the 1.91:1 aspect ratio for link preview cards. Because Facebook was the largest social platform, every other platform converged on the same dimensions to ensure compatibility.
The 1200px width ensures the image looks sharp on retina displays (2x pixel density). The 630px heightkeeps the preview card compact enough that it doesn't dominate the feed while still being large enough to communicate the content clearly.
On mobile devices, the image gets scaled down proportionally. On desktop, it fills the full width of the link preview card. One image, every platform.
Platform-by-Platform Size Reference
| Platform | Recommended Size | Aspect Ratio | Min Size | Formats |
|---|---|---|---|---|
| 1200 x 630 | 1.91:1 | 600 x 315 | JPG, PNG, GIF | |
| Twitter / X | 1200 x 630 | 1.91:1 | 300 x 157 | JPG, PNG (non-animated GIFs) |
| 1200 x 627 | 1.91:1 | 200 x 200 | JPG, PNG, GIF | |
| Discord | 1200 x 630 | 1.91:1 | N/A | JPG, PNG, GIF, WEBP |
| 1200 x 630 | 1.91:1 | 300 x 200 | JPG, PNG | |
| Slack | 1200 x 630 | 1.91:1 | N/A | JPG, PNG, GIF |
| iMessage | 1200 x 630 | 1.91:1 | N/A | JPG, PNG |
Facebook recommends 1200x630 for the best quality on high-resolution displays. Images smaller than 600x315 will still work but may appear blurry.
Twitter / X
Twitter's summary_large_image card uses the same 1200x630 dimensions as Facebook. Summary cards (small image) use a 1:1 ratio at 120x120 minimum.
LinkedIn accepts images up to 7.6MB. While 1200x627 is recommended, 1200x630 works identically since the difference is negligible.
Discord
Discord's embed preview pulls from og:image and displays it at the full recommended size. No minimum documented, but smaller images appear pixelated.
WhatsApp link previews use the OG image. Images are cropped to roughly 1:1 in the chat preview, so keep important content centered.
Slack
Slack's link unfurling uses og:image. Large images render cleanly; small images get upscaled and look blurry.
iMessage
iMessage link previews display OG images prominently. Images are shown full-width in the conversation bubble.
Aspect Ratio Explained: 1.91:1
The aspect ratio 1.91:1 means the width is 1.91 times the height. For a 1200px wide image, the height is 1200 / 1.91 = 628 (rounded to 630).
This ratio is a compromise between landscape aesthetics and feed readability. Too wide (like 21:9) and the image gets too thin. Too square (like 4:3) and it takes up too much vertical space in the feed.
Width ÷ Aspect Ratio = Height 1200px ÷ 1.91 = 628px ≈ 630px
If you upload an image with a different aspect ratio, most platforms will crop it automatically. This usually cuts off important content — which is why starting with the right dimensions matters.
Common Mistakes to Avoid
Using a screenshot as your OG image
Screenshots of homepages are too small, poorly cropped, and don't communicate what the page is about. Create a purpose-built graphic with a title and subtitle instead.
Making the image too small (e.g., 400x200)
Platforms will upscale small images, resulting in blurry, pixelated previews. Always use at least 1200px width.
Forgetting to set og:image:width and og:image:height
These optional tags help platforms size the image correctly before downloading it, which speeds up link preview rendering.
Using animated GIFs
Most platforms don't animate GIFs in link previews — they show a static first frame. Stick with JPG or PNG.
Putting text at the very edges
Some platforms add slight padding or rounding to the preview. Keep your text and important elements inset by at least 40px from each edge.
Other Social Media Sizes (for Reference)
OG images don't need to match every platform's native image format, but here are common sizes you might need for other social media content:
| Use Case | Size | Ratio |
|---|---|---|
| Standard OG ImageRecommended | 1200 x 630 | 1.91:1 |
| Twitter Summary (small card) | 120 x 120 | 1:1 |
| Pinterest Pin | 1000 x 1500 | 2:3 |
| Instagram Post (for reference) | 1080 x 1080 | 1:1 |
| YouTube Thumbnail (for reference) | 1280 x 720 | 16:9 |

What is the best size for OG images?
1200 x 630 pixels (1.91:1 aspect ratio). This is the recommended size for Facebook, Twitter/X, LinkedIn, Discord, Slack, and WhatsApp.
What is the minimum OG image size?
600 x 315 pixels for Facebook, though images at this size may appear blurry on high-resolution displays. Twitter's minimum is 300 x 157 for large summary cards.
What aspect ratio should I use for social media images?
1.91:1 is the standard for link preview OG images across all major platforms. This ratio balances landscape width with feed-friendly height.
Do I need different OG images for Facebook and Twitter?
No. Both platforms use the same og:image meta tag and the same 1200x630 recommended dimensions. One image works everywhere.
What file format should I use for OG images?
JPG for photos, PNG for graphics with text. Keep the file under 5MB. Avoid animated GIFs since most platforms don't animate them in previews.
