TikTok Caption Character Limit (2025)
TikTok allows up to 2,200 characters per caption (expanded from 300 in mid-2023). Despite the generous limit, shorter captions (50-100 characters) with 3-5 strategic hashtags consistently outperform long-form captions on TikTok.
TikTok Hashtag Best Practices
Use 3-5 hashtags mixing popular (1M+ views) and niche tags. TikTok hashtags are case-insensitive. Avoid banned hashtags that can suppress your content.
