Snapchat has more length rules than most platforms because a single Snap, a Spotlight clip, an ad, and a non-skippable Commercial all use different windows. This checker converts your duration to total seconds and tests it against every format at once, so you know instantly whether your clip qualifies or needs a trim.
How it works
The tool converts your minutes and seconds into a single total, then compares
that total against each format’s official [min, max] second window.
total seconds = minutes × 60 + seconds
fits format = total ≥ format.min AND total ≤ format.max
gap = total − max (too long) OR min − total (too short)A green tick means the clip qualifies; otherwise the tool reports exactly how many seconds you are over or under so the fix is unambiguous.
Example and notes
A 12-second clip fits a single Story Snap, qualifies for Spotlight, and works as a Snap Ad, but it is too short to satisfy the Commercial format’s intent of a 6-second non-skippable open with a longer body. A 90-second clip fits ads and chained recordings but exceeds the 60-second single-Snap window, so Snapchat will split it — plan your cut points around the 60-second mark so each segment ends on a hook rather than mid-sentence.
