Instagram captions can be up to 2,200 characters long, but the feed shows only the first 125 characters before a More link. Readers who do not tap More never see the rest — so lead with your hook, call-to-action, and most important text in those first 125 characters. Hashtags, emoji, and line breaks all count toward the 2,200-character cap. Use this Instagram Caption Counter to draft your full caption, track total character usage, and spot exactly where the truncation will cut off. The Instagram preset is pre-activated below — paste your text to see how it fills the character bar in real time.
