We believe the majority—if not all—of your content should be capped at _____.

The correct answer is 15 seconds. Twitter's best practices suggest that the majority of your video content should be concise, ideally capped at 15 seconds. This length is optimized for quick consumption on a fast-paced platform like Twitter, where users scroll rapidly through their feeds. Shorter videos are more likely to be watched to completion, increasing engagement and message retention. Videos longer than 15 seconds (e.g., 30 seconds, 60 seconds) risk losing viewer attention before the key message is delivered, as users may scroll past. While 10 seconds is also short, 15 seconds often allows for slightly more complex messaging while still maintaining brevity.
