AI Video Specs for TikTok, Reels and Meta Ads: Aspect Ratio and Resolution

Quick answer: Generate 9:16 vertical video for TikTok, Reels and Stories, 1:1 or 4:5 for feed placements, and 16:9 for YouTube and websites. 720p is fine for testing; use 1080p for final ads. Keep key text and products away from the top and bottom edges, where app buttons cover the screen. Check each platform's current specs before launch.

Choose the ratio before you generate

Cropping a 16:9 video to 9:16 later loses most of the frame. Decide the platform first and generate in that shape.

Quick spec guide

1. TikTok, Reels, Stories: 9:16.
2. Feed ads: 4:5 or 1:1.
3. YouTube, website, presentations: 16:9.
4. Test drafts at 720p, final at 1080p.
5. Keep products and text in the centre 'safe zone'.
6. Short clips (5–15 s) usually perform and render best.
