What is the difference between summary and summary_large_image cards?
"summary" displays a small square thumbnail alongside the text, while "summary_large_image" features a prominent, full-width header image above the title.
If Twitter tags are omitted, does X fall back to Open Graph tags?
Yes. If twitter:title or twitter:image are absent, Twitter/X will fall back to og:title and og:image, but specifying twitter:card is still required for large image previews.
What image dimensions should be used for summary_large_image?
Use a 2:1 ratio with minimum dimensions of 300x157 pixels, though 1200x628 pixels is recommended for high-resolution displays.
