This checker takes a single video duration and instantly tells you which Facebook formats it qualifies for — Feed, Stories, Reels, Live and Ads each have their own minimum and maximum second limits, and this tool checks them all at once so you never upload to the wrong surface.
How it works
Facebook enforces a min/max duration window per surface, expressed in seconds. The tool converts your minutes-and-seconds input into a total number of seconds, then compares it against each format’s window. A format shows green when your duration is min ≤ length ≤ max, and red otherwise, along with how far over or under you are.
For example, Stories cap at 60 seconds, Reels at 90, and feed videos at 240 minutes (14,400 seconds). A 75-second clip therefore fits Reels and Feed but is 15 seconds too long for a single Story segment.
| Format | Min | Max |
|---|---|---|
| Feed video | 1 s | 240 min |
| Story (per segment) | 1 s | 60 s |
| Reels | 3 s | 90 s |
| Live broadcast | — | 8 hours |
| Story / Reels ad | 1 s | 60 / 90 s |
Tips
- Aim for under 15 seconds for in-feed video ads, where attention and completion rates peak.
- If your Story video exceeds 60 seconds, Facebook auto-splits it — re-edit into clean segments for better pacing.
- Reels under 60 seconds tend to be surfaced more aggressively than the full 90-second maximum.
