Cheat sheet
Video ad specs, one honest table
Every placement in one table. Aspect ratio, resolution, max length and the sweet spot that actually holds attention, checked July 2026.
| Platform | Aspect ratio | Resolution | Length allowed | Sweet spot | Notes |
|---|---|---|---|---|---|
| TikTok In-Feed | 9:16 | 1080 x 1920 | 5s to 10min | 21 to 34s | Sound-on platform, captions still essential. UI covers roughly 130px top and 440px bottom, keep key content centered. |
| Instagram Reels | 9:16 | 1080 x 1920 | Up to 90s (ads) | 7 to 15s | Leave the bottom 35% and right edge clear of text, UI overlays live there. |
| Facebook Feed | 4:5 or 1:1 | 1080 x 1350 | 1s to 241min | 15s or less | 4:5 takes the most mobile feed real estate. 85% of feed video plays muted, design for sound-off. |
| FB / IG Stories | 9:16 | 1080 x 1920 | Up to 60s per card | 10 to 15s | Keep text inside the middle zone, top and bottom 250px get covered. |
| YouTube skippable | 16:9 | 1920 x 1080 | 12s min, no max | 15 to 30s | Brand and offer must land before the 5-second skip button. Front-load everything. |
| YouTube bumper | 16:9 | 1920 x 1080 | 6s fixed | 6s | Unskippable. One message, one visual, one brand frame. |
| YouTube Shorts | 9:16 | 1080 x 1920 | Up to 60s | 20 to 35s | Shorts ads interleave with organic, UGC-style outperforms polished creative here. |
| 16:9, 1:1, 9:16 | 1080p | 3s to 30min | Under 15s | LinkedIn's own data: sub-15-second ads see higher completion. | |
| Amazon Sponsored Brands | 16:9 | 1920 x 1080 | 6 to 45s | 15 to 30s | Autoplays muted in search results. Product in frame one, on-screen text carries the pitch. |
