About the X (Twitter) link preview card size
The X (Twitter) large link-preview card, the summary_large_image card, is documented by X as a 2:1 image with a minimum of 300 by 157 pixels, a maximum of 4096 by 4096, and a file under 5 MB in JPG, PNG, WEBP or GIF. The size almost everyone actually ships is 1200 by 628, a 1.91:1 landscape. That is worth being clear about: 1200 by 628 is Facebook's OpenGraph recommendation, not X's published number. It works well on X because the card crops to its own ratio and one image set as your page's og:image tag then covers X, Facebook and LinkedIn at once. If you want to match X's documented shape exactly, 1200 by 600 is 2:1 at the same width.

Frequently asked questions
What size image shows when a link is shared on X?
Most people ship 1200 by 628 pixels, pulled from your page's og:image or twitter:image meta tag. X's own documentation asks for a 2:1 image with a minimum of 300 by 157 and a maximum of 4096 by 4096, under 5 MB.
What is the minimum X (Twitter) card image size?
300 by 157 pixels, per X's card documentation. The 800 by 418 figure repeated across many size guides, including earlier versions of this page, is not a number X publishes.
Is 1200x628 an official X card size?
No. 1200 by 628 is Facebook's OpenGraph recommendation. It works well as an X card because the card crops to its own ratio, and using it means one image serves X, Facebook and LinkedIn. X's documented ratio is 2:1, so 1200 by 600 matches the spec exactly.
What aspect ratio is the X (Twitter) link preview card?
The X (Twitter) link preview card uses a 1.91:1 aspect ratio at 1200 by 628 pixels. 1.91:1 is the label the industry uses; dividing 1200 by 628 gives 1.9108, which reduces exactly to 300:157.

How this spec was checked
Platform sizes change without notice, so this entry records what it was verified against rather than stating a number and hoping it holds. Last checked July 27, 2026.
ConventionX (Twitter) does not publish a size for this surface. The number below is the one the industry has standardised on, which is a useful answer but not a claim about X (Twitter).
X's card documentation gives a 2:1 aspect ratio, a 300 by 157 minimum, a 4096 by 4096 maximum and a 5 MB file limit for summary_large_image. It does not publish 1200 by 628; that number is Facebook's OpenGraph recommendation, which works in practice because one image serves all three networks. Earlier versions of this page called 800 by 418 X's minimum, which X does not document anywhere.
What changed on this spec
- : X (Twitter) link card: the documented minimum is 300 by 157, not 800 by 418, and the documented ratio is 2:1. 1200 by 628 stays as the practical recommendation but is now labelled for what it is, Facebook's OpenGraph number. The wrong minimum also shipped inside this page's FAQ structured data.
