Why this tool exists
Captions that exceed a platform's limit get cut off or rejected outright, and each network's limit is different enough (280 for X, 2200 for Instagram/TikTok, 3000 for LinkedIn) that it's easy to draft for the wrong one. Social Caption Counter exists to check length against the right network's limit before you paste into the app.
Problems it solves
Writing a caption in a doc or notes app gives no live character count against the target platform's actual limit, so the first sign of trouble is often the platform itself truncating or blocking the post at publish time.
Common use cases
- Agency social calendar: checking a batch of drafted captions against each platform's limit before scheduling.
- In-house social manager: confirming a long-form LinkedIn post still fits before publishing.
- Pre-launch: validating campaign captions across Instagram, TikTok, and X before a coordinated multi-platform post.
- QA before spend: checking a paid social caption fits the platform's limit before boosting a post.
Honest scope
This checks length against fixed limits for instagram, tiktok, linkedin, and twitter (X) — hashtags count toward the total. Platform limits can change; confirm the current cap in-app before relying on this for edge cases near the limit.
