Social media caption character counter
Paste a caption and watch it count against Instagram's 2,200, X's 280, LinkedIn's 3,000, TikTok's 2,200 and seven more limits at the same time. Color-coded bars flash before a network truncates your post.

Caption limits by network
Hard limits cost you readers
Cross a network's character limit and the post is rejected at publish, or truncated mid-sentence behind a 'See more' tap that 70% of feed users never trigger.
Hidden preview ceilings
LinkedIn and Facebook accept long posts but cut feed previews at 210 and 250 characters. Front-load the hook in the first two lines, before the truncation point.
Hashtags count toward the limit
Hashtags consume body characters on Instagram, X, LinkedIn, TikTok, YouTube and Facebook. Only Pinterest and Threads exclude them. Stack tags in the comments on Instagram if you need the room.
