TikTok Captions That Convert in 2026
TikTok's algorithm now weights caption hooks almost as heavily as the first 1.5 seconds of video. A weak caption can sink a great hook, and a strong caption can rescue an average one. Here are the formulas, hook templates and a free generator.
The 5 caption hook formulas that work
1) Contradiction: 'I stopped working out and lost more weight.' 2) Specific number: '$47 changed my entire morning routine.' 3) Open loop: 'No one told me this would happen at 28...' 4) Direct address: 'If you're an introvert, watch this.' 5) Question + payoff: 'Why are croissants flat now? (Answer at 0:14)'
Length: 100-150 characters wins
TikTok captions cap at 4,000 characters but watch-time data shows 100-150 character captions perform best. Keep the hook in the first line, drop hashtags below.
