Twitter/X renders link previews using Twitter Card meta tags. The image size determines whether your tweet shows a large image card, a small thumbnail, or nothing at all. This preset covers the three most-used Twitter Card image dimensions.
| Name | Dimensions | Description |
|---|---|---|
| card | 1200x675 | Large image card — 1200×675px, the standard size for summary_large_image Twitter Cards |
| square | 1200x1200 | Square variant — 1200×1200px, used in promoted tweet placements |
| portrait | 1080x1350 | Portrait variant — 1080×1350px, matches Instagram feed dimensions for cross-platform repurposing |
The summary_large_image card requires a minimum 300×157px image and renders best at 1200×675px (16:9). Square images (1200×1200) are cropped to a circle on profile tweets. Portrait images (1080×1350) appear in some ad placements. Using a placeholder at the exact required dimensions lets you verify card rendering in Twitter's Card Validator before launch.
Add a placeholder twitter:image to your meta tags and validate in Twitter's Card Validator to catch markup errors before publishing.
Technical blogs shared on Twitter benefit from a compelling card image. Use a placeholder at 1200×675 to test the layout before the illustration is ready.
The 1080×1350 portrait size matches Instagram feed dimensions. Generate both in one session to test cross-platform design consistency.
