Quick answer
LinkedIn recommends 400 x 400 pixels for a Page logo and 4200 x 700 for a Page cover. For a Page post with a URL, LinkedIn gives 1200 x 627 pixels, or 1.91:1, as the display guideline. Use 1080 x 1350 as a practical portrait image-post canvas and preview it before publishing.
Source check: August 28, 2026. Platform apps, APIs, account types, and third-party publishers can change on different schedules. The final operational check is the preview and public result in the exact path you use.

What this page owns
LinkedIn Page art, post images, document posts, article covers, and URL preview cards are separate surfaces. A PDF carousel is not an image carousel; it follows document rules and should be checked as a document.
That ownership boundary matters. Boomp uses one clear page for each search job instead of publishing near-duplicate pages that give different answers to the same question.
A dependable production method
- Export logos without extra blank padding.
- Keep Page-cover text away from the edges and profile overlap.
- Set the linked website's preview image before sharing the URL.
- Use a PDF for a document carousel and verify every page.
- Add useful alt text or an accessible caption when the interface permits it.
The last check matters most. A design file, successful export, scheduler acceptance, or API response does not prove that the customer-facing artifact is correct.
Size is only one acceptance test
A technically valid file can still fail the business. Check these questions with the final media and caption together:
- Is every name, date, price, claim, location, and link current?
- Does the crop preserve the subject and the useful words?
- Are captions, contrast, and text alternatives sufficient for the content?
- Does the business have permission to use the people, customer material, music, footage, and marks shown?
- Does the call to action match the destination and what happens next?
- Did a responsible person approve this exact version?
For the full release gate, use the social media content quality checklist.
Where Boomp fits
Boomp fits when the recurring problem is larger than one pixel count. The free first look starts with a public website and returns ten finished posts, with images, a carousel and a short video, before asking for an account or a card. They are the software's reading of the public site and do not prove that Boomp knows the owner's voice. Publishing and the recurring month belong to the paid plans. Finished media and posts belong to paid work, with the customer's approval settings controlling what represents the business.
