OG Image Size: 1200×630 Pixels for Every Platform (2026)

The correct OG image size is 1200×630 pixels. That is an aspect ratio of 1.91:1. Save the image as PNG or JPEG and keep the file below 1 MB.

One image at this size works on X, Facebook, LinkedIn, WhatsApp, Slack, Discord, and iMessage. You do not need a different file for each platform.

OG image size by platform

Platform	Recommended size	Ratio	Limits
Facebook	1200×630	1.91:1	Below 600×315 the preview becomes a small thumbnail. Minimum 200×200. Maximum 8 MB.
X (Twitter)	1200×630	1.91:1	Needs twitter:card set to summary_large_image. Minimum 300×157. Maximum 4096×4096 and 5 MB.
LinkedIn	1200×627	1.91:1	1200×630 is displayed the same. Maximum 5 MB.
WhatsApp	1200×630	1.91:1	Keep the file small. WhatsApp can skip the image when the file is large, so stay below 300 KB if WhatsApp is important to you.
Slack and Discord	1200×630	1.91:1	Both scale the image down to fit the message.
iMessage	1200×630	1.91:1	Shows the full image above the title.

Why 1200×630?

Facebook set 1.91:1 as the ratio of its link preview, and the other platforms copied it. Previews are displayed at about 500 to 600 pixels wide. At 1200 pixels, the image has two pixels for each displayed pixel, so it stays sharp on high-density screens.

A larger image, such as 2400×1260, gives no visible gain. It only makes the file heavier and the preview slower.

The safe zone

Some apps crop the image. Small previews on X, WhatsApp, and iMessage can show only the center square.

• Keep text and logos at least 60 pixels from each edge.
• Put the most important content in the center 630×630 square.
• Do not put a logo in a corner if the card must work as a square.

File format and file size

• PNG for text, flat color, and screenshots.
• JPEG for photos.
• Do not use SVG. Platforms do not render it.
• Be careful with WebP and AVIF. Not all platforms read them. PNG and JPEG work everywhere.
• Keep the file below 1 MB. Crawlers have short timeouts, and a slow image is shown as no image.

Tell the platform the size

Add the width and height as tags. The platform can then draw the preview at the correct size on the first share, before it has downloaded the file.

<meta property="og:image" content="https://example.com/og.png" />
<meta property="og:image:width" content="1200" />
<meta property="og:image:height" content="630" />
<meta property="og:image:type" content="image/png" />

Common size mistakes

• A square logo as og:image. The platform shows a small thumbnail or crops the logo.
• An image below 600 pixels wide. You get the small layout, not the large card.
• A 16:9 screenshot. 1920×1080 is 1.78:1. The top and the bottom are cut off.
• Text at the edges. It is cut off in square crops.
• A 4 MB photo. It is below the limit, but many previews time out before it loads.

Check the size of your image

The OG image checker downloads your image and reports its real width, height, and ratio. To make an image at the correct size, use the OG image generator or the templates. Each one renders at 1200×630.
