Open Graph Placeholder Images — og:image Sizes

Open Graph images appear when your page is shared on Facebook, LinkedIn, Slack, iMessage, and most social platforms. A missing or wrong-sized og:image shows a broken preview that reduces click-through rates. This preset generates the three most important OG dimensions so you can test share previews before the real image is designed.

NameDimensionsDescription
og1200x630Standard OG image — 1200×630px, the required size for Facebook, LinkedIn, and most platform link previews
1200x12001200x1200Square OG variant — 1:1 ratio, used by WhatsApp and platforms that crop to square
800x418800x418Compact OG variant — covers older renderers and email client link previews

Why these sizes matter

The og:image spec requires at minimum 1200×630px for landscape previews. Facebook and LinkedIn display this as the main link preview. A 1200×1200px square image works for platforms that crop to square (WhatsApp, some Slack views). The 800×418 variant covers older renderers and email clients. Generating all three ensures your share preview looks correct everywhere.

Use cases

Pre-launch share preview testing

Drop a placeholder og:image into your meta tags and use the Facebook Sharing Debugger or LinkedIn Post Inspector to verify the layout before your designer finishes the real artwork.

CMS and blog post templates

Many CMS platforms auto-generate OG images. Use a placeholder at the correct dimensions to verify your template's text overlay and crop before enabling the feature.

Email newsletter link previews

Email clients that render link previews pull the og:image. Test at 800×418 to ensure the preview shows correctly in Apple Mail and Outlook.

FAQ — Frequently asked questions

What size should my og:image be?
1200×630px is the recommended minimum. Facebook and LinkedIn both display this size for link previews. Using a smaller image may result in blurry or cropped previews.
Why do I need multiple OG image sizes?
Different platforms render OG images differently. Facebook uses 1200×630, WhatsApp crops to square, and some email clients prefer a wider aspect ratio. Generating all three ensures broad compatibility.
How do I test my og:image before publishing?
Use Facebook's Sharing Debugger (developers.facebook.com/tools/debug) or LinkedIn's Post Inspector (linkedin.com/post-inspector) to see how your og:image renders. A placeholder at the correct dimensions lets you verify the crop before the final image is ready.
