Twitter/X Ad Best Practices (2026)
Ultra-Short Duration
6-15 seconds is the golden length for Twitter/X. Users scroll fast — your message needs to land quickly.
First 3 Seconds
Videos auto-play on Twitter/X. The first 3 seconds must deliver a strong visual hook to stop the scroll.
Captions Required
Most Twitter/X users browse in public or transit with sound off. Always include captions or text overlays.
Bold Visuals
Twitter/X's fast-scrolling feed demands high-contrast, eye-catching visuals. Avoid subtle or slow-building creative.
