Twitter Cards display preview images when URLs are shared on Twitter. The summary_large_image card type shows a large image preview at 1200x628 pixels (approximately 1.91:1 ratio), the same as Facebook's Open Graph dimensions.
To maximize engagement when your content is shared on Twitter, create a compelling 1200x628 preview image that includes your article title, brand logo, and an eye-catching visual. This image appears prominently in the Twitter feed.
With ImgTools, crop your image to 1.91:1 ratio and resize to 1200x628. Save as JPEG at 85% quality or PNG for images with text.
Implement the twitter:image meta tag in your HTML head pointing to this image URL, along with twitter:card set to summary_large_image.
