The ideal TikTok ad length is 15-30 seconds, with the hook appearing in the first 3 seconds. Agent Wise X creates ads that capture attention immediately and deliver your message concisely. We test multiple lengths and find that shorter ads (15-21 seconds) often perform best for conversions, while slightly longer ads (24-30 seconds) work better for storytelling and brand awareness campaigns.
