Quick answer
The standard full-screen vertical-video canvas is 1080 x 1920 pixels at a 9:16 aspect ratio. It is a strong working size for Instagram Reels, Facebook Reels, TikTok, YouTube Shorts, Stories, and full-screen Pinterest video. Each destination still needs its own duration, safe-zone, caption, and cover check.
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
Vertical is a shape, not a strategy. A useful vertical video still needs one clear subject, readable captions, an honest opening, and a next step that belongs on the destination.
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
- Shoot or design in 9:16 from the start.
- Keep key content inside a central safe area.
- Review auto-captions.
- Choose a cover that survives smaller previews.
- Export a destination-specific copy when context or rights differ.
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.
