Every Limit on One Screen
Paste your caption once and see it against every ceiling: X 280 characters, Instagram caption 2,200 (bio 150, max 30 hashtags), TikTok caption 2,200, YouTube title 100 / description 5,000, LinkedIn post 3,000. Green means it fits; red shows exactly how many characters must go. Hashtags are counted separately with the Instagram 30 limit flagged.
The invisible limits matter more than the hard ones: Instagram truncates captions after ~125 characters behind "more", LinkedIn folds at ~210, X shows all 280 but engagement drops past ~100. Front-load the hook — the first line does the work everywhere.
Frequently Asked Questions
Do emojis count as one character?
Platforms generally count user-perceived characters, but some emoji are multi-unit under the hood; X counts most emoji as 2. Leave a few characters of headroom when an emoji sits near the limit.
Do links eat characters on X?
Every URL is wrapped to a fixed 23 characters regardless of its real length — budget 23 + a space per link.
