Quick answer
Use 1080 x 1920 at 9:16 for short vertical video, 1080 x 1080 at 1:1 for a square fallback, and 1920 x 1080 at 16:9 for landscape video. Those are production canvases, not universal limits. Duration, file size, codecs, and account-specific permissions still vary by destination.
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
Dimensions answer whether the frame fits. They do not answer whether the video has captions, a readable first frame, truthful claims, licensed media, useful audio, or a safe crop.
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
- Choose the destination and job before editing.
- Keep captions and logos away from interface controls.
- Export in a supported codec and file type.
- Check duration and file size in the exact account or tool.
- Watch the processed result with sound on and off.
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 current first look starts with a public website and returns up to six website-grounded talking points before email. Those talking points are not finished posts and do not prove that Boomp knows the owner's voice. Email saves the first look and continues into post ideas. Finished media and posts belong to paid work, with the customer's approval settings controlling what represents the business.
Give Boomp your public website and review the first talking points before email.
