OG image aspect ratio is appropriate for LinkedIn

LinkedIn crops OG images that fall outside its preferred 1.91:1 aspect ratio. A square 1200×1200 image is cropped to a horizontal strip; a portrait 600×900 image is cropped to a narrow band. The crop is center-based, meaning headline text or logos placed toward the edges of an image optimized for other contexts will be cut off. Per ogp.me, the recommended dimensions are 1200×628, which maps to 1.91:1. Developers who create OG images for general use at square or tall aspect ratios discover the cropping problem only when they check the LinkedIn post-publish preview — after the content has already been shared.

Use 1200×630 pixels for all OG images. This satisfies LinkedIn's 1.91:1 ratio and is accepted by all major platforms. For ImageResponse-generated images, set the dimensions explicitly:

return new ImageResponse(<div>...</div>, { width: 1200, height: 630 })

For existing static images at wrong ratios, resize them with an image editor or a build-time sharp script. When designing OG image templates, keep critical content (text, logos) within a centered safe zone that accounts for the 1.91:1 crop.
